RE: Viper Q500 tips and techniques
another needed mod to the Viper . [ V- TAIL ] remove the center top block on the V-tail then remove about 2 inches of covering from both tail halves , top and bottom. add a 3 to 4 inch piece of light fibreglass cloth with epoxy or resin to the top and bottom surfaces. i say to do this as for no particular reason other than a poor build / glue job from factory my V-Tail halves separated , luckily the model was on the ground with engine idleing before take off.
