A few weeks back I was flying my Voyager E for the first time. I was practicing my hovering and had a few moderately hard landings. The tail rotor blades got a few little dings, but everything looked OK, until I brought it to a hover for the seventh time. After hovering for about 20 seconds at about 15 feet up the tail assembly exploded, and I had to make an emergency landing. The only parts at the end of the tail that seemed to be in fine shape were the two tail blade holders, the drive belt, the tail shaft bearings, and the plastic end that caps the boom. I had to replace all the other parts in the end of the boom. The rest of the heli was undamaged.
After waiting for three weeks for the replacement parts, I was able to give the heli another go today. Unfortunately, the heli spins quite aggressively in a counter-clockwise direction as it leaves the ground. Before each attempt, I was very careful not to have any tail trim set, or to apply any tail controls until the gyro light became solid. I tried centering the tail as per the direction that came with the Futuba GY401 gyro that is in the heli. They said to start the gyro in "head holding" mode and then switch to "normal" mode and adjust the trim settings. In both the "normal" and "head holding" modes the tail rotor blades looked right on the mark. Regardless of what I did with the trim in "normal" mode, the heli would spin counter-clockwise. I even maxed out the trim for clockwise movement, before attempting to take-off. No luck! (During several trials in "normal" mode I saw the tail blades strongly angled to produce a "clockwise" spin before starting, but the heli would still turn in a counter-clockwise direction as it left the ground.)
The heli is running a Hacker motor, so I had to create a gyro platform in the back of the heli to avoid interference with the gyro. This arrangement worked like a champ before the tail blew-up... The gyro is mounted straight and level.
There is no one that flies helis here, and I'm a real novice. Any help would be appreciated.
