My one flew very well it was faster then my habu with the p20" unfortunatly mine crashed on its 7th flight due to pilot error i stalled it on the turn slowed it down to much and pitched the nose up it has very small wings i did notice it was abit unstable flying at slow' speeds the bd5 is a fast jet with a p20 and can eat up the sky in seconds with a p20 however good for pilots that like fast stuff but not for those who like slow scale flying if you build one keep it light very light im sure it wil fly alot better i added stuff like retracts pilots in cockpit, lights this just added the weight up" altho nice model
