thanks for advice.dont know if it was a coincidence, but belt was definitely slipping today. never noticed it before but i could hear something clicking as it span round. i tightened it and it was ok, so hopefully that was the problem and not just a coincidence.

unfortunately the least of my probs as my test flight ended spectacularly badly. on a not particularly heavy landing upright on the skids, the whole head (incuding both blades etc) suddenly sheared off the main shaft just above the main shaft, and shot 15 foot across the lawn.

damage - the sheared off part at the top of the head that the feathering shaft goes through, 2 mangled esky digital servos, one missing turnbuckle linkage! my tail fin also snapped off- anoyingly lost its bracket in the grass.

not sure if accident was caused by the blades hitting the ground or not, but the blades were hardly damaged and the feathering shaft was not bent. might have just had a fracture from a previous impact or something

so anyway, thats me grounded for a while, loads to repair <br type="_moz" />
