I got a yama/xrc2 buggy a couple years ago now cheap of a friend. My issue is I have a couple of mods on it(air filter, cheap chinese exhaust). My problem is I've tried find some accurate information on what speed i should get out the Yama. I've seen all sorts from 30 mph to 45 mph(i don't think i would ever get 45 mph). I've used a couple off apps on my phone and sent it for a drive and the fastest a can seem to get is 27 mph. Does anyone know if I should be getting better speeds? It seems to run quite well I just think it's a bit slow. TIA
