Welcome to the wacky world of the Trex!!! Its a great heli, mine is going well...I was doing loops with it on Christmas Eve...and then did some piro/stall turn type moves...and ended up crashing...glitched at low level.
Walked up to where she lay, landed on long grass which cushioned the blow...Heli was unbroken save for a slight bend on the flybar....blades were folded back.
2 minutes later,,,up again but with some more careful flying
I use the 325 plastic blades, quite heavy but very tough.
I added an extra o ring either side of the feathering shaft, this stiffened the head up a lot...tracking stays put and response is a little bit more crisp.
I fly mine a lot, a light to moderate breeze is ok. I fly at work...football pitch...in the evenings...the only improvement I can think of is..get another couple of chargers and an extra battery...to take it up to 4 batterys
