if you want to be able to pull out of a hover and not want it to look like a OLD man getting out of a broken down chair,don't use a DA 50 on a 18lb. plane! use a larger engine or a lighter plane,like a QQ yak, EF yak ' or a Ultra RC yak all can be built at 16 lbs or less. i have a Double Vision at 17lbs. it needs help out of a hover with a DA 50.
ENJOY!
