Going BL on my Savage
 

I just fell onto you guys. Any advice on set ups? I am into crawling but would still like to bash a bit. I have reverse and a 3 speed installed. Lots of aluminum due to my nitro bashing days. Extended Chassis and MIP CVD's all around.

I just ordered the brushless conversion kit from Kershaw Designs with the 13T pinion and I ordered a 9T pinion.

Any suggestions would be great.

Thanks,
John

I would go with like a 9xl. You could run on 14 cells with good power and still have a fair speed.

What is a 9xl? I purchased a conversion kit from Kershaw Designs. It comes with a 13T Mod1 Pinion and I ordered a 9T. I am new to this. What would be my best setup for brushless. Like I said I have the 3 speed in it. I would like to be able to do some minor crawling and have the speed for bashing.

Thanks for your help.

John

Please read the sticky in the brushless section, i think it will offer you help.

Thanks Serum

I appreciate your help.

Anytime!

If you have got another question, please feel free to ask.. It's not my intention to scare you off with pointing you to that FAQ, but i think it's a relative easy to understand story with useful info for 'starters'

I'll tell you what...I got into rc rock crawling about a year ago and am active on rccrawler.com. It is amazing the willingness people are to help people through a hobby. It is so great to say that I am part of this interest. Most of the people I talk to are very willing to help or point you in the direction you need. My excitement is doing the research and picking other peoples brains.

Thanks again,
John

Great!

I think with the help of Brians speed calculator you can find your way in choosing a motor and the right pinion. if you need any confirmation, just post your choice.

OH BTW. Welcome to the forums.
I thought that may have been you on the rccrawler forum.
You have the same sig on there.
Do you have a txt as well?

TXT and TLT

What is your name on RCC?

I am not a member on there.
I was there looking around some.
I just purchased as txt myself.
I got a thread around here some where on it.
I was thinking of joining over there.

They are great guys over there also.

Here are my rigs...

The orange one is a TXT...

OK here is what I am looking at:

1) Brushless…not sure yet…probably Lipo

2) Currently running 40 series Moabs tires.

3) She weighs in at a wopping 13 lbs. That is with all the nitro stuff still on it.

This truck is hopped up with a lot of aluminum and HD drivetrain. It has the 3 speed tranny and reverse. I would like to rock crawl a little but mainly backyard bash. I am out of the nitro scene and tried to sell it. Too much into it to sell so I thought I would go this angle.

I do have some of the plastic stock parts that I could put back on to lower the weight.

How about this setup:

Feigao 9L with a Castle Creations Phoenix 80 (not sure if I am going Lipo)

Any thoughts.

Thanks for the input.

John

They nice man. Thanks for posting them.
I haven't got mine yet. I got some for buying purposes.
It is stock for most part. I don't want an all out crawler.
Something more like you have planned on savage.
I was wonder if could put a 3 speed on a crawler with 4 link suspension.
I think that be kind of tight.

I wouldn't go phoenix for it is a airplane contoller.
4s lipo 10L motor and a castle mamba maxx with ubec would get you going
nicely. It wouldn't be a speed demon.

You will see a lot of guys put the emaxx tranny on a TXT. You need a servo for changing gears but set up the right way will give you the crawling and then shift to some wheel spinning fun.

I kept the TXT tranny. It is strong and smaller than the emaxx

Ok. I have a trans and the truck comes with a new kit for it.
I have a few servos laying around for shifting.

And can you shoot a pic of your savage. she needs a diet! aluminum is nice, but useless.. the savage in stock form is beefy as it is. Only thing you need in aluminum is the diff-housings.. the FLM bulkless is too heavy IMO.

OK here is where I am so far. Buddy had an HPI Low CG CF Chassis for a good price...free. I have aluminum diff cups that I never installed.

I took the nitro stuff off and the tires and it dropped the weight to 8lbs.

What do I do with the brake? Will I use it or the esc brake?

Should I get lighter tires?

In the RC-monster store they show a servo plate to get rid of the box. Is that worth doing to lighten up and open it up?

Should I eliminate the stock motor plate and just put aluminum spacers?

I am also going to replace my uprights with the stock ones.

Thoughts so far???

If you run a two speed the mechincal brakes have to stay. You will need a y harness for servo and esc to run off same channel.
Cf chassis is a great deal. hard to bea the price.
The servo plate is up to you. Not necessary but a preference.

Now you have me really confused. I am using a three speed. Why can't I just use the esc brake? How would I wire it?

I am guessing that Reverse would be a third channel function.

Thanks,
John

It is cause of the one way bearing.
It is needed as well for when it shifts to 2nd and 3rd the shaft spins faster than
the gear it is on does. When you apply the esc brake the motor will only stop
spur. The truck is like in free wheel mode. Yes the reverse would be on 3rd channel.
You only need a y connector for like a revo steering servos.

UPDATE:

I have got the rig down to about 6 lbs before wheels and tires. I ordered Proline Wabash 40's and Crimefighters for the weight savings and an extra 1/2 inch offset.

I am dealing with Kershaw Designs on the motor plate and he has a Nemises 6XL with a Castle Creations Phoenix 125. Is this a good combo?

My question is what would be a good Spur Gear/Pinion combo? I am looking for backyard bashing and speed to smoke the nitro guys. :dft012:

I will probably run 14 cells for now...going to LiPo in the future.

Let me know your thoughts.

Thanks,
John

the 6XL is too hot for 14 cells. better of with a 7 or 8XL.

PS Mike has got a template for the motorplate as well. you can shoot him an email about it. he has got a warrior 9920 controller for 150 bucks, which is fair priced.

with the phoenix 125 you need to use the mechanical brakes, and most likely a stick transmitter.. It's got some issues with pistol grip transmitters.

It's possible that Mike has got a singlespeed conversion for the savage soon. (fixing it in 2nd speed)

You have my head spinning now.

I was told that they Phoenix 125 would be the way to go especially if I decided to go LiPo. The Nemesis 6XL I am able to get at the price of a 8XL so I thought that would be the way to go.

I have already ordered the BL conversion from Kershaw...I have no problem with that. He is designing me a Low CG mount.

My confusion is in the Motors, ESC and Batteries.

If you were building a BL Savage basically as a Backyard Basher and occasionally kicking some Nitro Ars, What would be the best combo?

Motor:
ESC:
Batteries:
Spur:
Pinion:

Note: Truck will weigh about 8 lbs loaded...Three speed tranny...lowered suspension...Spektrum DX3 Radio.

Thanks to all that respond.

John

:032:

I not sure how well the phoenix will do. It is made for planes not mt.
The 6xl I would rather have a 7xl. You could look at a 9920.

It is obvious that you guys know a heck of a lot more than I do. I got into this because I wasn't going to run nitro anymore.

I really need someone to point me in the right direction. Buying a motor and esc is not a cheap investment and I would like to do it the correct way.

Can you tell me:

Motor:
ESC:
Batteries:
Spur:
Pinion:

I know everyone has different ideas of what is the "best"...I just want something to bash.

I was originally going to go with a Phoenix 125 with a 7XL. That is when you stated that I would need to use the mechanical brake with a "Y" to the servo. Are you saying that I need to go a different direction?


HELP...:032:

If you keep the 3 speed trans you will need the mechical brake.
I just don't know how well the phoenix will do.
If it was my truck. I would buy the 9920 and a 8xl feigao.
Gearing would start at the 15 52 and see how it does on temps.
For batts the 8000 mah lipos are great. You would need a lvc for 9920.

You could go with a mamba max as well with a ubec but I personally have no
experence with them yet.

Thank you that is what I was looking for. I have know experience with this and a wrong purchase can be an expensive mistake.

I will see about getting something more like what you are stating.

Thanks,
John

Can I run NiMH with this set up until I jump into lipos?

Yes the nimh would be good. Get a temp gun if you don't have one.
You may get few pinions for the up and down movement of your gearing.

What did you mean by the last sentence?

Confused????

I ran the selection thru the calculator. I think I told you to slow on pinion.
15 49 will put you in the 28 mph range on 4s lipo. So you can go up on that.
I am not sure how fast you are shooting for either.

I want to be able to beat Nitros. I am thinking 40-50 mph. Is that asking too much?

Why do you feel the Phoenix will not work? I understand that the 6XL may be too much motor. Would a 7XL be more in line or should I go to the 8XL?

Thanks for being patient with me.

John

Well for the cell count you running it will require more amperage.
If you want alot of speed and power up the cell counts.
6s will get you there alot faster than 4s will. Rene on here is more of a
savage man than me. I have only built one. It was with the 3 speed to.
It is easier to get higher speeds with more voltage. A 9xl on 6s is a power
house that will get you there fast to. I wasn't sure on speed you wanted.
It is not problem man. I just want to make sure you get the proper system.
Hate to give wrong advice. If you shooting for that speed I would step it up
on voltage.

Who is Rene? I cannot find a User Name...

This truck is only for fun and to try something different. Should I be so concerned with this or what?

I am doing more thinking on this rig than my two crawlers.:035:

Oops. Serum is rene. sorry.

OK guys here she is.

I put her on a diet and dropped a wopping 4.5 lbs off her.

She now sits at 7 lbs in the pic. I will be running 40 series Dish 23MM with Crimefighters. That ads another 2 lbs.

To keep the lower CG I have softened the springs so I have more droop. I will adjust once running it.

Any thoughts.

Looks really good! You should have one sweet truck when its brushless. If someone hasn't already said it, you really should run a plastic spur. The pinions get all chewed up on a metal spur due to the massive torque they produce...
