| MX-400 Center T Problems!My MX-400 had a bad Center T from the factory!
I checked the blades before use for balance weight etc and they were ok. The heli shook on rev up and the blades were out of track about 5mm, but after the head speed came up the blades would then track and they would stay in track as long as the head speed stayed up. I got about 10 flights before the head pooped off during a flight. I made a turn and the heli lost some altitude, I poped the collective and pulled back on the stick and the head pooped. I was about 1 foot from the ground and forward speed was almost stopped. The T hub had broke, the blades were ok, the main shaft was ok but the T hub was broke and the levers and rods were broke. After the 5th flight or so the startup shake problem had stopped, probably because the plastic had stretched.
I replaced the head with a T-Rex XL head parts and used my Shogun 285 carbon fiber mah blades. I have over 60 flights on the machine now with no head problems. I also put a T-Rex SE tail box on it, I did not like the plastic tail blade holders, I have had this type of holder crack at the blade screw.
I called Hobbico about the Center T problem 10/31/2005 and they said they would send me a replacement. Hobby Services invoice date was 01/13/2006, I got the replacement part near the end of January 2006.
I had the MX-400 fixed after the head poped off within a week with T-Rex parts. |
