Finally, an update!
I have been working on this, trust me! One of the most difficult tasks that I had to overcome was re-mounting the engine from the rear of the trans to the front. I had to do this so that the engine would not stick out of the back of the cab!!!
The main argument then becomes, get the trans far enough back from the front axle and yet far enough ahead to that it doesn't stick out of the back of the cab... and of course low to enough so that the front driveshaft doesn't bind.. and yet high enough so there's clearance... and on and on...
Here's where I sit now: 3 servos installed: steering, 4x4 shift, and 2 spd shift, ESC, and Receiver:
RC4WD Dig Trans:
Here's with my mods to mount the motor on the front of the trans:
I'll post a video of the front axle engaging/dis-engaging, but for now, here are a couple of pics. The 4wd servo barely travels at all:
Engaged in 4x4:
Dis-engaged:
Next up, mount the body, enclose the rear and do some bodywork!
