If you want to stick ( Pun intended) get the Etronix Pulse EX3GPro version it has plenty of adjustable and programmable features for low cost compared to Futaba/Sanwa prices. I've raced using one indoors and out with NO problems.
Worth getting a Transmitter Lipo from HobbyKing ~$20 inc delivery

Only need to top up charge every 3 or 4 weeks
