The stock electronics in my RTR bomber did a great job of getting the truck around, but there are no adjustments available to fine-tune how it performs. I ended up swapping out all of the electronics with higher-end stuff to improve performance, tunablity, and durability. A Tekin RX8 speed control replaced the stock unit and can be fully tuned by using the mode button on the top or by connecting it to my computer through Tekin’s Hotwire programming device. I mounted it as low as possible in the chassis on a custom-made carbon-fiber plate mount. The RX8 is connected to a Tekin ROC 412, which provides the speed of a 35-turn motor but the torque of a 55-turn motor. The Vanquish aluminum wheels that I installed added some extra weight that would be hard on the stock servo, so I upped the game with a HS-7940TH servo; it puts out 222 oz.-in. of torque when powered by 7.4 volts. That will get the job done! For control, I stuck with Hitec and went with its Lynx 4S so that I would be able to adjust things like endpoint, expo, and so on. Power for it all comes from a Maxamps 2S Lipo battery, with a hard case for
Tekin’s RX8 is a smooth speed control, with lots of adjustments that will let me dial in my Bomber. I mounted it to a custom-made carbon-fiber plate.
