RE: nitro rustler
I got one as a first truck, and I wouldn't recommend it. Start off a little smaller, maybe even on electrics. Go for a nitro sport for a 1st nitro. And yes, get a failsafe. My truck took off at full throttle once while I was still breaking it in, some servo wires got melted by something under there.
Also, I have a couple questions, on the OS website, it said that the LC3 glow plug was for traxxas trx 2.5 motors, and then I went to order it on tower hobbies and it said it was just for the t-maxx and shouldn't be used with a trx 2.5R. So a trx 2.5 and a trx 2.5r are different motors, correct? And is the LC3 a good choice for a nitro rusty?
