Well Ace,
After reading your post and all that you plan to do and how high you plan on jumping, and after careful consideration, I am going to have go with the other fellas and recommend the Arena. It is a much lighter truck and wont be as likely to destroy itself, the nemesis is one bad assed truck and would handle landings from those heights if you land it on the wheels, but if you happen to land on the top of the engine, Unless you have a cage that can take it, you could do this:
It might surprize a few here that I would recommend the Matrix TR over the Nemesis but if you think about it, and take into consideration what you plan on doing with it, then it just makes sense. The intended abuse you will put it thru WILL break it!! And there is no sense recommending something I know you will break!! A truck this size and weight will make a dent in the dirt if land wrong, but Arena wouldn't.
