This is my first crawler build (actually my first RC build aside from a heli I built in college) so I have no idea what I'm doing. I'm attempting to install the R2D tranny in my R1 tuber chassis. I've seen bikerzee's install thread for the Stealth chassis and, as he noted, the Stealth chassis is a bit roomier. I ordered the R2D tranny before I even got the R1 Rock Buggy kit and have chewed my nails down to the quick as I've calculated and researched, wondering things like if the R1 chassis even had the width to accommodate the R2D transmission. I'm happy to report that it can and does. The other problem that I anticipated was interference between the rod end of the rear, upper, right suspension link and the endbell of the motor. As you will see, If I'd gone with anything longer in the can than the 55T Integy Lathe Motor, things would not have worked out.
I installed the transmission as far forward as possible on the delrin skid plate. Due to proximity to the preexisting mounting hole, I was forced to go with only 3 screws.
Doesn't get any closer than this! Rod-end barely touches the endbell! (rear, right, upper-link rod-end shot from above)
Same thing, but shot from below.
Front lower links have sufficient clearance.
Here's a shot of the rear from below and aft.
And the front.
I'm doing cytogen's battery tray mod, but I've had to trim the tray to accommodate the savox SC-1251MG that will be used to drive the disconnect. In this shot, you can see what I have to work with space-wise in the cockpit. I'm going to mount my receiver on the radio tray that I have moved to the rear of the cockpit (where the battery tray was.)
So. There it is. Assuming that I can shoe-horn the servo and mounting kit into the space between the tranny and the ESC tray, it is possible to cram an RC4WD R2D tranny into the stock R1 chassis.
I forgot to mention that I had to trim 12mm of of the front and rear drive-shafts.
