nothing in the $200 dollar price range(if you are talking the complete package) is going to work if you want to rent them out. no ready to run kit will last. the servos that come with rtr kits dont last very long and neither will the parts.
kyosho makes a 1/10 nitro buggy for under $300 but i have never seen it in person. kyosho makes good product though. still the servos will not last long.
