I've been watching Youtube and noticed that the Leopard 1 is quite a speedy thing. there is a great clip of a Canadian one leaping off a ramp and firing while in mid air. Trouble is I cant work out if I should get mine to go a bit faster. Actual speed of the real beasty is 40.6 MPH, scale that down to 1/16 and that equates to a pawltry 2.5 MPH. I'm thinking perhaps a bit of poetic justice to get it a bit faster, perhaps 4 MPH would be nice.

What would be acceptable for you lot? do you stick to correct scale speeds?
Thanks!
