here's what happened I tried putting and edf 40 on, and it would only fly for like 2 minutes, I was going to go lithium but decided not to after reading some horror stories. So I put the old tail motor back on after getting a new boom (had to shorten the boom for edf40) and now when I hit the throttle I get NOTHING...the servos work and I believe the speed control is getting some signal as when I push the throttle it goes from green to red. Also when I turn it on it blinks green 4 times, goes to red for a second and then back to green. any help would be appreciated. thanks!
