Predator 500 RIP. Some things are just not meant to be. After sawing off the tail and gluing it back on it was finally flying right. Ant then some kind of a control failure. I'll never know for sure becuase all that was left was littly bitty pieces. One brand new RX... gone. One 1600mah battery... mia. But almost everything else survived. The engine needs a throttle arm. But it seems OK. This part is, of course, back ordered.
The good news I bought a Sonic 500 last weekend. Had it's first second third and fourth flight today. I like it a lot. It may not be as fast as the Predator 500. Or so I've read. But I think it makes a terrific sports plane. And it's not a V-tail
Thanks again for the help.
