RE: Vortex Q500 Kit
AMEN to that!!!! I have built many vipers that's why I approached chuck about letting me do the vortex in 424 version also, it might cost a few more bucks, but the quality of construction, the quality of how it will fly will far outweigh the price tag in the end. You will have to go very far to make a viper race ready for 428, I wouldn't trust it at all with that kind of power in the nose.
