Vintage RC Helicopters - Schlüter SX-81
SX-81 Build manual - German version in Hi-res only. Tail gearbox assembly - 1985 article with hints for assembling Schluter tail gearbox and tail rotors.
Head removed and stripped for inspection as ‘wobble’ noted on flybar pivot and main head pivots. Wear found in side cheeks as the pivot bush had worn the cheeks so bushes ‘epoxy’ glued in cheek plates and also the holes ‘closed up’ to grip the bushes by ‘centre popping’. Head now only ‘nipped’ up in order to keep it tight on the shaft but now have the movement inside the head block and not the cheek plates (can be reverse engineered if new parts found). Bearing on flybar pivot also had play due to being loose in the housing and the centre pin worn; again refitted with epoxy to close up the gaps. All other bearings OK and head rebuilt; checked and now no unwanted movement; main shaft checked and found to be straight so head refitted. Another heavy machine but quite sprightly and had good collective response. General figure eight flying and nothing too adventurous undertaken as it was quite blustery though nearly lost it in a large circuit as I allowed it to slow up when travelling downwind and with the rate gyro it spun round backwards; only judicious use of forward cyclic and full pitch got it moving forwards again and saved the day...!!!
