RE: SONIC 500
yes to be on the safe side i might add a couple of carbon fibre strips to the wing. going by my Viper wing which i must say is very strong and also quite heavy that little extra strengthening on the Sonic wont hurt. actually the way things seem i wouldn,t be surprised if the Sonic goes quicker than the Viper due to weight difference anyway. any other tips would be gratefull, thanks guys.
