Rummy's Savage E-5SC
 
First some questions.

I want to run a 1717. I've been reading up about the Alza mounts for them. What do you guys think about using these mounts with the TCS TVPs? Will I have to do a lot of hacking on the TVPs? I plan to run a Mamba XL on 6S with the 1717. I have a 1520 right now but bigger is better right? :lol:

Got a Savage roller a week or so ago with the TCS plates already. It's basically just a Savage 25. I'm not upgrading anything yet. I'll break stuff first. haha

As of last night I had the battery boxes on and have a flux trans ready to drop in (with plastic spur). I also have the motor mounts hogged out for the 1520. Like I said, still thinking about just going to the 1717 depending on what you guys think.

This showed up yesterday.

Easier to pull all the parts I need and part out the rest than buying the parts individually. Heck the body alone is $210 and not in stock....

Working on assembling wheels and side body mounts so that'll let me mock up the body mounts and get an idea of ride height. I'm planning on using SS front shocks all around and have the HPI 24mm savage adapters. Probably have to go to XL stubs to get the right track width?

Feel free to give input. Good to be back on the board. Been a while since I've had an electric rig worth posting!

Rummy out.

Yes you will. I'm not even sure that the 1717 will fit length-wise with the TCS TVPs. The 1520 should be able to be mounted with a bit of grinding for to account for the length over the motor over the stock.

You can always grind out the Flux mounts to fit either the 1520 or 1717. I've got the GCM mounts for a 1520 as I was planning on mounting this up, but ended up putting it in my truggy.

FYI, I'd just go ahead and get the bulletproof Flux diffs, you *are* going to break the standard diffs very quickly.

NickRummy 06.21.2011 04:12 PM

The 1717 is actually shorter than the 1520 according to Castle's site. Not by much, 3/16" or so. I already ground the mounts for the 1520, you can see it sitting in the second picture in the OP. I'm just thinking about going to the 1717 now instead of spending time on the 1520.

thzero 06.21.2011 04:15 PM

I would just grind the mounts for the 1717 then.

NickRummy 06.21.2011 04:31 PM

Is there even enough room? I took off quite a bit for the 1520 and the 1717 is a lot larger in diameter.

How do you like the 1520 in your setup? Isn't that what you're running? What all did you have to mod on your TVPs to do it?

Actually I ran the 1800kv in the 5T as I put the 1600kv in my truggy. I was running the 1800 on 6S, thought it ran cooler than the standard 2200kv. I basically had to grind out the rear of the motor cutout area of the TVP (see attachment, the area where the red circle is).

Please do it with the 1717 - As this is what I want to do...

JasonB 06.21.2011 09:51 PM

1520 rocks!
 
I think the 1520 is more than enough to push that truck around. A 1717 would get less run time, wear out the truck faster due to excessive torque, heat up the batts quicker due to larger current draw, etc. Other than looking cool, it's a loose loose with the bigger motor. Just my opinion.

You have no idea what you are talking about.

A 1717 would be the logical choice as it produces more torque. It has a larger diameter stator so it will be able to procue the needed torque.

I have run both the 1520 and the 1717 and the 1717 is the clear choice winner for a heavier vehicle, and a longer wheelbase vehicle.

I ran both with a MMM and a zippy 5kmah 40c lipo. No heat issues on the esc or lipo with either but you could feel the torque difference with the 1717 and it ran cooler...

Nothing against the 1520 but it is a good 1/8 mt motor. Get much bigger and you need a larger motor. I would like to see a 1725 motor, around 1400kv for 8s use with the MMmxl.

But this is just my opinion too, sure I may have days of runtime with hundreds of brushless setups but what do I know...

NickRummy 06.21.2011 11:39 PM

I am picking up a 1717 tommorrow! I think I am just going to make my own clamp mounts. I have some 5/16"' aluminum plate leftover from another project that should work.

I can see the point in a larger motor wearing out a truck faster but the other points? A bigger motor with the same or equivalent kv rating is going to work a lot easier than a similar smaller motor.

I got the 5sc wheels on tonight and set the body on because i couldn't help myself. Internet is out at home so posting from my phone. Will have pics posted in the morning after I get to work.

NickRummy 06.22.2011 09:08 AM

Ok photo time. 5SC wheels and tires are mounted up on stock savage axles with the hpi 24mm adapters. Front track width is 16.25" and the rear is 16.75". It's not THAT far off really.

http://i736.photobucket.com/albums/x...r/IMG_3642.jpg

Flux tranny mounted with the motor plate in. Going to start drawing the 1717 clamps today. Pretty much just going to copy the Alza mounts.

http://i736.photobucket.com/albums/x...r/IMG_3643.jpg

I'm picking up the 1717 today at lunch and I'm hoping I'll have time to assemble the side rails from the 5SC kit so I can see how they'll attach to the TCS plates.

Interesting. Well, I have never run a 1717, so as linc suggested, I can't speak from experience on that motor, only based on everything I've read on other related forum posts, which is as I stated earlier, it is an amp hog. I do run a 1520, and can confirm that it is a torque monster, quite efficient, And total overkill for my standard length Savage - wouldn't have it any other way. Best of luck on your project, hope it goes well . . . Looking great so far!

NickRummy 06.29.2011 01:37 PM

It's nice to see some good progress FINALLY. Finished the plastic mock up channel and mounted up the side rail assembly with the stone guards too. Actually worked out really really well. Putting the flux battery boxes back on is going to take some serious thinking though.

http://i736.photobucket.com/albums/x...s/IMG_3654.jpg

http://i736.photobucket.com/albums/x...s/IMG_3655.jpg

I'm going to make a center skid. The stone guards cover up the sides nicely but the open bottom of the TCS conversion bugs me.

http://i736.photobucket.com/albums/x...s/IMG_3656.jpg

Some body on shots. Springs are really soft and the plastic channel for the body mounts is sagging but it's pretty close to the ride height I'm going for. Can't wait to get in the XL axles to widen out the track width.

http://i736.photobucket.com/albums/x...s/IMG_3657.jpg

http://i736.photobucket.com/albums/x...s/IMG_3659.jpg

http://i736.photobucket.com/albums/x...s/IMG_3660.jpg

Time to make the aluminum rails since the plastic ones worked out well then start assembling the front and rear bumper assemblies so I can get started on those.

thzero 06.29.2011 01:46 PM

You could also just put the batteries inside the TVPs. Granted it does raise the CoG a bit as they have to sit over the driveshaft; see my thread for what I did.

Seems that it needs to have a slightly wider track.

NickRummy 06.29.2011 01:47 PM

I've debated about the battery going in the middle. I don't think it's a bad option. The battery boxes will have to be raised slightly to clear the new side mounts anyway.

I posted in the pics that I have XL axles on the way. That'll give me 1/2" more width per side.

thzero 06.29.2011 03:34 PM

Yeah that will help then. Think you will still want to do something akin to my axle mod especially if using the XL axles.

NickRummy 06.29.2011 03:55 PM

I have a sleeve I'm going to try first. You know how on the adapters I made for you there is a shoulder in between the 24mm hex and the bearing in the knuckle? I think that's why the XL axles have a problem. They have nothing to support them when they flex and the weakest point is at the thread where they are tightened down. I'm going to make some of these beefy sleeves and try them out and see how it holds up.

_paralyzed_ 06.29.2011 05:34 PM

I don't know what the side pieces from the 5sc kit are called, but I'd just throw the batteries there, one on each side. Mount some straps and call her a day.:yes:

I'm not sure I'll want to rely on them holding the weight of the batteries when it's being bashed hard. It's just two plastic support arms that hang off the chassis. The stone guards that go under the side body mounts are just a thin flexible plastic that wouldn't support anything. I might split the side body mounts up into two pieces instead of the one long channel. That might give me some more room on the sides.

thzero 06.30.2011 12:00 PM

Yes, I'm pretty sure you hit on the head. Be interesting to see if beefy sleeves solves the problem; if it does, certainly a less of a hassle solution.

viction 07.05.2011 04:42 AM

Some FLM extended arms would fill in that body perfectly.

NickRummy 07.05.2011 09:08 AM

It was sloooooooow weekend in the RC shop. Way too much to do around the house and for the holiday. I got nothing done. Almost!

I did get one of the spacers done for the 24mm hexes. I'm hoping these will help beef up the axle flex.

XL stub with stock purple spacer and new larger spacer

http://i736.photobucket.com/albums/x...s/IMG_1682.jpg

http://i736.photobucket.com/albums/x...s/IMG_1683.jpg

Here it is in place. My thought is that since it's sandwiched in between the hex hub and the steering knuckle this will help cut down on the amount the axle can flex on hard landings, hopefully keeping the threads from snapping off like they're known for?

http://i736.photobucket.com/albums/x...s/IMG_1686.jpg

Overdriven 07.07.2011 07:58 PM

What you've created looks alot like an extended hex, except that it is in 2 pieces. What about taking an extended hex with an 8mm bore, and drill a hole for the drive pin in the correct location. It'll be all one piece, and might support the axle better. Only issue then is you might want to use a sleeve or something on the threaded portion of the axle. Just an observation, and throwing out an idea. Cool truck man, I love those bodies.

Exactly what I would want to do, build a one piece extended hex but there's a lot of machining time tied up in that 24mm hex with the threaded end. I'm hoping this will work well and it's way easier than machining a one piece part. Time will tell.

Alza motor mounts came in for the 1717.

Some clearance issues

"Trimmed" the TCS plates :lol:

http://i736.photobucket.com/albums/x...s/DSC_0015.jpg

Overdriven 07.14.2011 05:07 PM

I forgot about the 24mm hex size of the wheels and the savage 5t hexes you already bought. Yea I'd try my best to make them work instead of modifying something else and then wrapping them with aluminum tape for the wheels. Like I said, just an idea I was throwing out there. Back to the regularly scheduled build. Looking good btw!

Dj_Sparky 07.15.2011 04:09 AM

The Savage 5t chassis' motor mount area is almost as large as the normal Flux chassis mount area, which is sort of weird imo. They should have given the motor mount area way more space, since this is a 1/5 size chassis, and people might want to upgrade the motor as well.

It's identical. But yeah, they should have maybe moved it forward a bit, maybe not as forward as HPI did with the XL frames, but still. TCS really didn't do a great job of thinking everything through with it.

NickRummy 07.15.2011 04:24 PM

Plus it's a 5T conversion but there's nothing there for mounting a 5t body? I've always been one to build from scratch so it doesn't bother me but for someone who wants to do a bolt on upgrade, this ain't the kit.

I forgot that the top of the chassis plate needed trimmed more to allow the mounts for the 1717 to clear the chassis plate. Here's a few pictures before the chassis was trimmed for the motor mounts. I finished up the trimming today so now the motor can move front to back the whole length of the motor mount slots. I should have a 44t spur here next week.

NickRummy 07.21.2011 03:20 PM

Roll cage is in! Almost..... The chassis plates are just a hair too tall to get the front of the roll cage to attach. No big deal, I'll make some spacers or use something like this.

http://i736.photobucket.com/albums/x...e/DSC_0024.jpg

Not real happy with the current aluminum side mounts since I had to hack them up to get them to work but they do work. I'll probably remake them at some point but for now I'm sick of working on the middle of the truck......

FINALLY time to start tearing out the unneeded savage parts and getting these 5SC bumpers and body mounts mounted.

NickRummy 07.26.2011 09:20 AM

Finally some fun updates with good progress! 44t steel spur installed on the trans, 15 pinion installed on the 1717 and all meshes up well. Did some fitting with parts and came up with a game plan for the rear bumper assembly.

Couple new holes in the stock 5SC bottom plate.

http://i736.photobucket.com/albums/x...e/IMG_3787.jpg

Pretty nice fit! I need to copy over the outside lines of the stock savage plate so that this plate will fit inside the hinge pin braces and need to trim the front of it so that it'll fit inside the TCS plates but it's actually a really nice fit. I'll have to figure out a few more mounting points too. These 2 holes are all I used now just to get it in place and see how things fit.

http://i736.photobucket.com/albums/x...e/IMG_3788.jpg

Everything in place minus the stock savage tower. I'm going to try and modify the stock baja upper plate to tie into the TCS plates to stiffen it all up.

http://i736.photobucket.com/albums/x...e/IMG_3789.jpg

http://i736.photobucket.com/albums/x...e/IMG_3792.jpg

http://i736.photobucket.com/albums/x...e/IMG_3790.jpg

FFRC cage extenders put up front. Looks like this will work out well. They're not the right diameter (since they're meant for the back of the cage) and a little long on the bottom but nothing that a dremel and a few minutes won't fix.

http://i736.photobucket.com/albums/x...e/IMG_3791.jpg

Body on shots.

http://i736.photobucket.com/albums/x...e/IMG_3794.jpg

http://i736.photobucket.com/albums/x...e/IMG_3793.jpg

I'm gong to work on copying over the outside edges of the stock savage plates today. Once I get that done I'll mount it up and move to the front since I know the back is where it needs to be. I need to try and get the body out to paint here soon so I can get it back in time for the 1st run!

Don't think I haven't thought of that piece of the puzzle. It's just not a priority at this point.....

NickRummy 07.26.2011 03:18 PM

Got a little more done at lunch. Enough that I can now move on to the front and worry about details later.

Trimmed down the FFRC extensions and used a body clip. They work great now.

http://i736.photobucket.com/albums/x...e/IMG_3799.jpg

Some notches on the baja bottom plate and cut the sides off to fit inside the TCS plates. This was a bit of a pain......

http://i736.photobucket.com/albums/x...e/IMG_3795.jpg

Set in place

http://i736.photobucket.com/albums/x...e/IMG_3796.jpg

Should be a nice strong and smooth bottom. I think I'll be able to use a stock baja skid too.

http://i736.photobucket.com/albums/x...e/IMG_3798.jpg

NickRummy 08.05.2011 02:42 PM

Today was a good day for the 5SC! Figured out the front end after scratching my head for the last week.

Used the stock savage skid with the 5SC front skid bolted to the underside of it. I used all the stock shock tower/body mount parts from the baja but oriented them a little differently. The shock tower supports that drop down behind the tower had the front cut off.

http://i736.photobucket.com/albums/x...l/IMG_3806.jpg

Here's the back side with the modified supports. The white plastic is a mock up panel for my servo plate which will also have the tower supports mounted to it.

http://i736.photobucket.com/albums/x...l/IMG_3807.jpg

Shock removed so you can see where I trimmed the support. If I really want to I could use a long bolt and fasten this to the savage shock tower.

http://i736.photobucket.com/albums/x...l/IMG_3810.jpg

How the body sits on it.

http://i736.photobucket.com/albums/x...l/IMG_3809.jpg

Bumper clearance.

http://i736.photobucket.com/albums/x...l/IMG_3808.jpg

Finally the body mounts are all in place and figured out. Now I just need to go back through the whole truck and complete it and do the finishing parts and pieces. Going to take a little while to do the shock mounting since the body mounts are in the way but it shouldn't be too bad. Most of exciting of all, the body is shipping out to be painted monday!

NickRummy 08.18.2011 02:46 PM

Thanks for the replies guys! Funny thing is.... I parted out the 5SC SS kit and it ALMOST paid for itself. I think I ended up paying about $150 for the body, wheels and tires and all the pieces and parts I kept. If I would have bought the parts individually I would have dropped probably $600+

Been a while since an update. Been working on it every day at lunch break but it's been all piddly stuff. Here's some new pics.

17lbs without motor, batteries or ESC. Still lighter than a 2WD Baja but heavy none the less!

Went ahead and drilled through the shock tower and tied the shock tower braces in. This made a HUGE difference in the front end.

http://i736.photobucket.com/albums/x...s/DSC_0001.jpg

New setup for the rear end. Cut down the stock baja bottom plate and put the stock savage plate underneath. The savage plate fits like it should and has all the stock mounting spots so I know this will hold the truck together correctly. The baja plate has 4 matching holes that will be used to mount it plus the savage skid will go on top and have 2 more additional holes clamping it in place. Should be pretty solid.

http://i736.photobucket.com/albums/x...s/DSC_0002.jpg

Made a steering link using 8-32 threaded rod and Revo rod ends. I'll probably sleeve it with something to dress it up a bit.

http://i736.photobucket.com/albums/x...s/DSC_0003.jpg

Some over all shots of it sitting on it's own with complete 5SC dressings!

yesterdays progress (documented by crappy cell pics)

Chassis braces attached to chassis plates just over the center drive shaft. You can also see the new mounting setup for the aluminum angle. Countersink from the inside so the batteries can slide in.

Heat bent some ABS to make a basic tray.

Tray sits in as so. I'll probably have a few different sets of holes in the tray so that the pack can be moved front to back for weight distribution. I have about 3" overall of room front to back.

Overall shot showing batts in place. Just need to figure out a strap system over the top.
