This is for a scale ship that is gaining weight as I build it.... the "no-carb diet" is NOT working! I fear it may not even be able to hover!
I did the search here on RR about putting an OS91 SXH into an XCell ST mechanics. stacked frames. I have the new style (no set screws) bevelled clutch bell. The OS91 seems to fit like the posts state it would.
PERCEIVED PROBLEM: the lower collet fits perfectly, but the UPPER COLLET does NOT go far enough down the engine shaft to fit into the fan housing so that it is flush with the top of the fan core. Obviously this top collet has a smaller inside diameter but it does not side down as far over the base of the output shaft as it does when installed with the OS61. The top of the fan is able to rock back and forth, as the upper collet does not contact it. The collet sits about 4 to 5mm away from it.
Is there a part number for the Upper Collet, or a part number for the set, etc. to make this new engine installation work?
All help is greatly appreciated, THANKS!
