New Trial Truck WIP

[z3_2drive]

Hello everyone, and Merry Christmas! I'm back with a new idea for a trial truck- large scale 4 link suspension, powered by a buggy motor coupled with an xl motor for high torque and high speed, from there a driveshaft runs to the 'transfer case' and then to a telescopic driveshaft going to the axle. Need to figure out a good steering system to fit on the axle (suggestions welcome). Made pictures and a video. I used simple adder so I can use the torque of the xl motor with the speed of the buggy motor, seemed impossible to stop with fingers. Pics:

shortly after video I added in a 'model' (sounds better than fake) v8 engine:

Everything is nice, but i don t understand why you use xl and buggy motor together.

So then you get speed and torque at the same time... good concept

Called an Adder. Check out Sariel's book explaining transmissions and motors.

Looks fery promising

One buggy motor gives u also a lot of torque and also speed.

But when there is too much torque required, the XL motor can just spin the RC motor instead of the driveline.

I think the xl would spin the axle instead of spinning the rc motor because the rc motor is turning with it as well. I cant wait to see how the whole truck comes out, great concept!

UPDATE: New pics of nearly-finished axle, braced/reinforced-now just need to figure out what to do for steering... Looks good, clearance: 7 studs under axle and 11 studs under center of chassis Made BL order for some parts like wishbones and pulley wheels for rear suspension/driveshafts, and got myself (finally) some wheels from the 8448 super street sensation, since they have good design for steering geometry and realistic tread. Pics of trial truck progress:

left front tire(underneath buggy motor) will rub against the buggy motor if steered under full flex, but I can just avoid that...

Hope everyone likes it so far and I REALLY hope this works out ...wish me luck!

Looking good!
