yeah. the xp3 radio is good for bashing but the spectrum radio's are more convenient......and a lot nicer to hold as well. they come in different grip sizes. 3 I think. the starter is ok. it's better than pull start. but a box is definitely the way to go. (not a must though)
the .28 mill won't get you turned away from the track either. I know two separate individuals that run them on the track around the corner from me. because it's an RTR, they don't care much.
