BloodClod's Twin Force (new chassis pics added)

My TwinForce has not seen action for many many years ever since my mtronics ESC died on it. A 14.4v ESC wasn't easily available here so the truck pretty much sat on the shelf. After running my brushless clod recently I remembered how much I liked "the force" and some ideas started churning.

Although the truck currently sports a custom chassis I made many years ago, I've some plans for a new chassis.

In the meanwhile, I wanted to get her running and decided to see how well this truck would run on a single brush less 540 motor and a single 2s lipo pack. I thought she'd be underpowered but boy was I wrong! Took her for a spin today and thought I'd share a video of the truck at the local buggy track.

I'll post more pictures of the truck later.

hey dominic! it's really nice to see so many familiar "faces" still championing RCMTs!

Sadly I sold my USA-1 a long long time ago. While the fully sassy-fied truck was awesome to look at and truly reflective of the designs and materials of that era, the USA-1 transmission was never as smooth or felt as "refined" as the clod's in my opinion. For me, I also bent a number of Sassy arms and axles for the USA-1 which made it hard to bash the truck with confidence.

You still have yours? I recall chatting USA-1s with you and Perry! :)

The RCMT world seems to have changed somewhat though.... lots of scale "monster jam" style racing these days eh?

I could not have been picked as USA-1 moderator and not keep my USA-1 lol =) i still have my original Usa-1 16 years later and i have one i picked up from BBeaty i rank it in top 4 best USA-1's ever done besides the one he kept for himself .. bent a sassy arm myself M.Hesse making custom arms for them .. and on axles only the 6mm ones resisted bending ..but to rare to bash at this point except going to run Bbeaty one at worlds next year it run really well and i have enough parts for 3 more usa-1's .. though don't run any of my trucks much i just caught the Quadcopter bug lately

My original in current condition


My BBeaty Usa-1

Here's a pic of the truck with my first custom chassis and a hummer shell




Spent the last week designing and cutting parts and here's how the truck looks now.



It's late now... more pics and info on the chassis tomorrow. :)

The chassis for the truck has been made from both carbon fiber and G10.

The suspension plates that run the length of the links are made from G10.



They serve a 3-fold purpose : first they provide the same reinforcement as the turnbuckle trick does, reduces the flex of the suspension arms to prevent the drive-shaft from ejection or damage, secondly, they serve as the mounting point for the shocks and lastly, they also act like anti-roll bars by increasing the axles resistance to "twist".

As a result of these plates, the overall flex in the truck is reduced. I think this actually improves handling in a race truck but I need to do more runs to confirm this. I'm thinking of experimenting with plates of different thickness to adjust the truck's roll.



Here's another picture of the plates and the chassis. The chassis has been machined from carbon fiber and has a very low center of gravity - the truck doesn't wheely now like it did previously. I am currently running a pair of 3.5" Losi big bore shocks which are very nice but the truck can be setup to use longer or shorter shocks. There are multiple adjustment options both for the upper and lower mounting of the shock for suspension tuning.

Currently masking the shell for painting. :)

Really nice! Are you still using the mad force tranny?

Thanks Yama-Bro. Yes I am still using the stock transmission as it is something I really like about the twin force. Center tranny is simple yet very reliable... Not to mention that chain just looks so nice and raw! Lol!

i love it...

if you ever do change the thickness of the plates, i'll be first in line to buy that chassis from you...

with a link-mounted shock setup, hows the torque twist? i know the braces you made act as swaybars, but are they enough to keep the torque twist controllable?

Thanks. Are you thinking I should go thicker or thinner on those plates?

To begin with the twin force in stock form already doesn't display much torque twist. If you check out the video above you can see the truck launches pretty much hard and flat.
