Well it would seem the the general consenceous on the Hyper Viper is that it is not bad. Does have fuel tank problems and the .049 that comes wiht it is some what lacking in the power department due to a restrictive air intake. The plane seems to be a good size 1/2A and for $50.00 it would seem you can't go wrong. Sounds like I will pick one up if my baby lightning suffers from a leathal case of gravity poisening. I would rather spend the money for the Viper and bang it up than put my OS .15 and JR. lightning in and have to pick up the pieces. Even though it is not painted up it is still my first real plane.
