hell if they're 17 bucks i'll buy 2 (just in case). and yeah, i love my hyper 7 it runs like a beast and sounds good, i just hate the pull start, but a starter box will fix that. i mean it was 300 bucks, so why would i spend 800 building a losi 8 when i can buy an ofna thats rtr, i'm not looking to win any races, just finish them
