It will fly,

I am a Scale Builder of Giant Warbirds and all my planes weigh more than there supposed to because I make them true to scale and this adds weight. Just fly it like the other Gentleman said, like a real airplane. Not everyone wants a rocket. Real normal planes don't go vertical or hover and I know this because my full scale Piper PA-28 140 will barely get off the ground on a hot day with a high Density Altitude and full fuel with three people inside. If I only fill it half way it will get off nicely. Don't use a huge fuel tank or at least don't fill it up and conserve weight.

JMHO,

Gibbs
