In reply to GTX Slotcar, I dinged up the baldes alittle and lauched the tail rotor blade. I decided to put the $23 plastic blades that I got at www.Hobby-Sports.com on. That's when I had the big one that I didn't get on vid.. The plastic blades snapped the tail boom in half and shot the training ping-pong ball across the yard. After I put the new Bell/Hiller upgrade on I noticed that the main shaft is slightly bent. It's not to bad though, VERY little wiggling. With the Bell head, this heli really flies like the choppers on AFPD. BTW I put the woodies back on. I can't wait to get the nuts to try the aerobatic paddles on and really screw around. I'm going to wait untill I can afford it though
