I noticed when seeing the 3Styla flys that it does some perfect harriers, and I was thinking that is this because the wing is below the thrustline?

If a wing is on the thrustline it would be still genrating lift wheras a low winger would genarate very litte and hopefully be more prone to stalling, which is what you need in a harrier right?

Also one of the RCWorld people mentioned they chopped the tips off and it wing rocked in the harrier, so a combo of these two elimnate it or is it something else?

Thanks
