RE: How fast is fast?
I have the Nelson F1 motor on the Vector. I recored 177mph in a dive, turning 21,000rpm on the ground using APC 8x7. I haven't use 60% nitro yet.
Now on my Evo, from bigbruceracing.com, I use MB Profi, Bruce's prop combo and new tune pipe, I get 29,500rpm on the ground. its 210mph in level flight and 235mph in a dive with no wind.[>:]
