I am a 42 year old novice. I have a revo 3.3 which I love to just bash around. When it comes to a crash a good part of the time i can't even fix myself. Having said that, in terms of tuning it runs like a top! I seem to read a lot of complaints online about getting it to run right. I have mine dialed in and barely if ever need to make any adjustments. Seems extremely easy.
