If you want a setup which will support and allow rotation - make a second rotating ring at nose of model and suspend the engine between the two - I did this years ago working on YS emgines
The forward ring was attached to fuselage via four angled, tubular pieces of carbon fibre
the whole contraption worked very well but a pain to build
I made my own Rotomount for years -did same thing as the expensive mounts -
Dick,
Did you play at all with the front webs? I read on your thread that you have yours hard mounted so there would be little use to drill and tap the front webs. I am planning to use the area for some angle stock and rubber snubber to lock the nose softly. That is one approach to a solution for the nose ring.....
A more elegant solution could be built in at the factory: the front bearing housing could be made oversized such that a slot could be milled for the sensor to slide into. The outside diameter would serve the function of nose ring mount just fine without interfering with the sensor. Meat could be removed from the extra diameter to lighten, just like they did for the prop drive washer. This area then would be similar to a glow front bearing area for inserting the nose ring. An aluminum ring could be machined and fitted to the front bearing housing and could do the same thing, but is less elegant....
If the pattern community showed enough interest in using this engine, then the factory might be persuaded to do something about the nose ring installation. That's a very big IF
