love the Kyosho st-rr. and before people say they are pricey and parts are not easy to find..... for one you get what you pay for and you have to break a part to buy one. Besides Amain carries everything for them. Handle like a dream and tough as nails. But i hear the Hyper ST pro Kit is very good as well and i will be picking up one of those to compare to the kyosho.(just dont know when yet, funds are low)
