Thanks. It took about a week of tinkering after work to come up with it. The cost wasn't that much. I think I may have $75 in it including all the twin force tranny parts, hardware, and aluminum stock I bought. So far I haven't broken a thing since I built it. Everything is holding up awesome. Only thing I have done is tighten up the drive cup set screws from time to time. All the torque they see tends to loosen them up even with loctite on them.

Thats a real nice rig you have there!!

What kind of speed is it going? How different are the ratios of the TF and the Emaxx?

I have no idea on the actual speed, but it seems to be as fast or faster than a stock savage 4.6. My overall gear ratio from the motor to the wheels is roughly 24:1.

What do you guys think about that gear ratio? Performance wise, when I peg it, the front goes skyward and the rear spins to the point that the tires balloon. It also seems to have no problem topping out. Do I need to possibly gear up some. I'm running a 10L/9918 on 14 cells. Keep in mind this truck is pretty heavy and it is a basher not designed for speed runs by any means. Could I possibly benefit by gearing up a bit?

No worries about that gearing ratio..

I did a 12 to 1 with a 2200 kv motor..

So you don't think my truck is geared too low? It's actually violent at a wide open start and tops out quickly like it could possibly use a "taller" gear.

If it runs fast enough for you then it good. If you got the gear to do it with you can try it. Keep and eye on your temps. If they drop or go up. If the drop you did good. I am running about a 20.5 to 1 on a 14 lb emaxx. I have first gear to. Mine does good. I only running a 1800 kv motor.

Gearing strongly depends on the diameter of tires ;) but I assume you're speaking about Savages.

Nice RC, BL_Force. I like it!

Smartass... ;)

dafni's a mod? When did that happen? Nice setup! get a vid of it!

A vid of Dafni? dancing naked on the table?

I'll get some vids when I get my video camera back from being repaired. I got it out this weekend, and it was broken.

LMAO
Serum, I never said naked. It's just Dancin onna table

BL Force, one question. This black thingy on the TF motor plate, right behind the tranny mount, where the motor sits. What's that for? I never ever installed this on my TF. It got in the way of my motorbrace.

It's just a pad that the motor can rests on to help support it when landing jumps. I decided to include it because the twin force motor mount is a little flimsy. One of these days I will get around to fabbing a beefier mount.

@dafni.. Must have been my mind, playing tricks on me...

I haven't posted much about my truck lately. I've been too busy bashing it. :) My design has proven itself to be very durable. I haven't broken anything to date, and I beat the poop out of it all summer. I bought some new monster gt wheels/tires off ebay Monday. They should be here tomorrow. My truck is geared just a tad low, so the taller tires should work great. I also just received my CNC wheel hexes for ACNCM, and they are very nice. They have an o-ring that retains the pin. I will take some new pics and maybe if it's nice Sunday, I will finally make some vids to post.

I always thought this was a cool project, but there's no way I'd tear apart my Twin just to make my Savage have a better driveline. :D

Not better Dabid, just different.. :)

The savage has got a near bullet proof drivetrain (exept for the 2nd speed) but HPI worked out that problem as well (it just takes so much time ..)

It would be nice to have a vid of your truck BL_force!

Thanks. :) Actually, I managed to find all the parts I needed on ebay really cheap. Now, it seems finding these parts is next to impossible since tower hobbies dropped kyosho. Glad I have a few extras just in case!

Well, as luck would have it....I will have Kyosho stuff available within 1-2 weeks, and have already ordered the twin force battery trays, as I know many folks are looking for them.

Sweet, Twin Force trays are the best out there!

I raced my Savage today, think I killed something in the tranny, gonna start looking on ebay to see how much this type of conversion would be.......just to kind of price it.

Let me know what died in the tranny, my guess is that the 2nd speed failed. that ring came loose or the pawl got stucked, or the pawl killed the 2nd speed gear. No biggy, HPI has got a heavy duty 2nd speed. The savage tranny is very reliable, in germany they use it with 24 cells and a 2240. (exept for that 2nd speed part)

The 2speed transmission is nice imo. It gives the truck a better acceleration and a higher topspeed.. So i would leave that on if i where you.

I recently got a Truckzilla Savage and I'm thinking of going brushless. I really like the mod. I thought about dropping a 3spd trans from a Mad Force in it with a nitro motor but seeing these brushless monsters in action I just have to make it electric.

The only question: what parts do I need to make this modification or is this modification not possible because its a Truckzilla version? (larger then stock Savvy)

Any help would be verry appreciated.

Thanks,

PWND from The Netherlands

Welcome to this forum PWND
And another dutch man.

The things you will need to go bruhsless
motor wandere 7, 8, or 9 XL
controller 9920 or 12020
battery's min14x and max20x
Ubec or reciever pack
Good battery loader
motor and battery brace make your own.(look on this site)
Or buy a conversion kit from germany

And just look around on this site because most qeustions are
already been anwer't

GOOD LUCK ANOTHER DUTCH SAVAGE BOY
;)

Heya Mack!

thanks for the welcome. Yup Dutch guys seem to have the strange habbit to turn there Savvy in to a brushless beast :L:

Thanks for the help with the brushless combo but I really meant the Twin Force tranny mod. If this would work on a Truckzilla Savvy. I'm sorry if I wasn't that clear.

Thanks for the help so far I appreciate it.

Welcome to the forum!!

Hey, is there a stock nitro Savy left in Holland at all?? :D

Way to go, mack. I would say the truckzilla is as easy converted as an ordinairy savage.

even with a Twin Force tranny? Sorry for being a noob :o

Sure. The center plate has to be custom made anyway. (truckzillas have wider TVPs, right?.

Hi pwnd, i happen to know you from the rc-racingcars, if you use the same username on those boards?

The most important thing to modify to your savage is to get your diffs beefed up. AND your drivetrain.. (depending on the amount of power your planning of using) FLM is currently making a bulkless setup for the savage.. About the transmission. i would use a savage 3speed. It's beefy for sure and it would make the conversion a tad easier as well. (shoot for yourself, i personall don't fear a bit of work...). Eversince it's a truckzilla, with bigger wheels as well, i would seriously beef up that drivetrain. Don't expect the 14mm truckzilla wheels to last forever though. They will die on you pretty quick.. 23 mm is the key to succes with a heavy BL powered savage.. (or good RPM rimms, though they won't last forever either)

I think Nitro offroad sucks because I already blow up two engine's on my savage that's why I am getting BL.
I got some on road nitro they are good tho
And I got a gasoline offroad that's a killer two, but it make's to much noise for the neighbourhood.

Rebuild time
 

Well, I'm nearing the completion of a total rebuild of my Savage. My diffs were both leaking fluid and I wanted to clean it all up real good and inspect everything. I'm also swapping all the hardware to stainless. During the teardown, I found about four teeth on the rear ring gear were in the process self destructing. :027: I've got all the parts on order to get it in like new condition again. I am also reconfiguring the battery trays. I am moving them about one inch forward to center them on the chassis. Hopefully this will get the wheelie problem under control, balance out the chassis better, and eliminate all the understeer I am getting while under power.

I finished up my rebuild tonight. I swapped from a 16T to a 18T pinion and added a savage x roll bar. I also re-engineered a few little things here and there. I'm ready for action this weekend. :028:

Looks like new now. Nice work.

Now all you need is some FLM extended LCG chassis plates and you'll be set! ;)

Well, I just wadded it up on a 8" iron drain that was sticking up about 6" out of the ground. :005: I took it to work today to show my bud with a stock emaxx what a real truck is, and caught this pipe which was hidden in a little grassy patch at around 30mph. It hit squarely on the left suspension, which immediately stopped the truck, broke the lower arm and treaked both tvps. LOL. Oh well. I picked up replacements on ebay, and I am in the process of tearing down again. :005:

dude you got to watch that stuff. Can't play long like that.

Yeah, no kidding. lol. All I can say is that I cringe to think what it would have done to my E-maxx. I'll have it running again next week. :027: Lesson learned. Don't go WOT across unfamiliar terrain. :005:

Well, I'm all back together again. I went ahead and installed my 17mm buggy style hex conversion kit, so I am waiting on my Savage X wheels/tires I bought off ebay. Hopefully, they will be here tomorrow. :027:

Got my wheels today. I'm ready to go again!
