Traxxas EMaxx 3906 Servo hole cover - Passenger's side

thingiverse

I thoroughly enjoy fiddling with my trusty Emaxx 3906 and have been giving it a thorough cleaning to get it in top shape. Many enthusiasts, including myself, often opt to disable the shift system and remove the servo, which leaves behind a sizable opening in the chassis that can be quite unsightly. To keep my setup looking neat and organized, I designed two distinct types of servo hole covers: one with a receiver post and another as a plain slab to cover the gap. Incidentally, my Emaxx 3906's front and rear axles have been "RPMed" out with their a-arms, hubs, and bumper kits. The transmission case has been flipped over to balance the weight of the powerful 775 motor with a gearing system consisting of a 20t motor pinion paired with a 72t spur gear, all thanks to a Robinson Racing kit. To accommodate the transmission flip, I've connected the motor leads in reverse (red to black). Furthermore, I've modified the transmission itself for a brushless setup by upgrading it with metal gears and repining the crank gear, while also disabling the two-speed shift. All of the shafts have been upgraded to the newer 3.3 standard, and I'm using 3905 wheels. Finally, I'm utilizing a Kimbrough large heavy-duty servo saver paired with a high-quality servo.
