so a few weeks back I flew my 300 heli in the backyard and it went berzerko, rather the signal had been interrupted and the heli went sideways into a stand of raspberry shrubs before coming to a rest. What does this have to do with multis and flyaways? Let me tell you I was astonished when the heli turned back on but was in a position only to wreck itself, fortunately it found some gear teeth that had been damaged earlier as the motor spun again, dodged a real close on if it was in the air I'll tell ya.
Take the heli inside and go to power the tx lipo which requires removing a rubber foam soft back I made for it. Guess freaking what? as I remove the foam I see the antenna is slightly loose, ohh no, and can you deduce where the signal cut outs were coming from? Yup, LOOSE ANTENNA. Mines a screw in type just like the dji ones, other manufacturers use them also, MAKE SURE, ABSOLUTELY CERTAIN, IT IS TIGHTLY
fastened on the tx, OTHERWISE,
