Magnum 57

[gasfreak]

Hey I just put a cc racing pro modified motor in a warehouse hobbies magnum 57 and man does it fly the problem I am having is the prop just blows out when you first get on the gas and in the corners once it catches up it flies I am running a 270 right now I tried a 275 but it cut the top speed and rpm quite a bit has anyone had any experience with a 470 I like the top end that the 270 gives I just dont like the slipping taking off I even tried to lower the strut does anyone have a better idea
