Hi Nigel, have some questions for you..
1) Did you have any problems with the OS55AX running inverted?
2) Did u use a pump or regulator to ensure smooth running?
3) What glow plugs did u use??
4) Standard OS Muffler being used?
I have always wanted a pattern plane to go with my 55AX too but held back cos I was afraid of potential inverted running problems.
Care to share how you avoided these problems?
Thanks

I had the 55AX on my previous pattern trainer, a TM Shadow. It was an inverted assembly with rubber engine mount, nose ring, Karl Müeller manifold and Asano pipe. Exellent running engine. Absolutely no problems running the engine inverted. I've heard the stock muffler is very noisy, but have not tried it myselff.
I used the standard Os#8 glow plug, 15/15 Aerosave fuel and a 12x6 APC prop. The planes' weight was ~2,4kg, and had unlimited vertical.
The attached photo shows the engine configuration.
As for the Osmose built, I have not had as much as a minute in the building room for a couple of weeks... (hence the heading "SLOW.."). I'm hoping to spend a couple of hours building in the end of the week or over the weekend.
