Hello Im building a Blackfoot ReRe and wonderings the best mods for this model. This is going to be a runner, so want to get the best of it. Here is my list so far, any other suggestions? 1. Ball Bearings 2. shimmed diff or MIP 3. included TBLE-2S with a 13.5t-17.5T sensored motor (stock gearing) 4. Savox 1258 Servo 5. Centered Servo Mount (https://www.ebay.com/itm/274123441523) and a heavy duty servo saver that zeros back out. 6. Round Style 4000-5000mah Lipo
