Cool thread! I wish I had seen this before my son built the version offered by Vonado. We just made a YouTube video about the whole experience. We also built a lever to toggle the on/off switch with the older style battery box. Here is a link to the spot in the video where we built the lever.
Like you guys mention in this thread (and worse with the Vonado version), the rotors put a lot of strain on the motor (you'll see how bad/slow it rotates in the video). Vonado's version comes with the older large power function motor. We ordered the newer Control+ motor which is a little more powerful.
We are going to attempt Ngoc Nguyen's gear mod to see if that will help out situation.
