Also, i need a failsafe and i was looking at some cheap failsafes like the futuba and duratrax one and they say the you cant use certain batteries like alkalines or NiCd batteries with them. Is this true? ALso, with the Ofna failsafe, it does list any batteries that you shouldn't use with it so should i go with that? Because i normally use NiMh AA bateries but i recently got some alkalines... Also, will the S3305 break if i end up cartwheeling my ravager again? AND finally, will Duratrax LR3 T-Maxx glow plugs work on the ravager? Right now im using a glow plug from my bro's tool box and it owrks fine ( its a t-Maxx glow plug cause thats his only car). And thanks ahead of time.

EDIT: Another question, will the S3010 servo give me more braking power or is it probally a problem with the cars brakes? Becaue right now, the brakes work only when im going fast and i can hold the brake totally donw when its going pretty slow (less then 10 MPH) and it barely does nothing.
