I have the Hanger 9 25% Cap that I am using a home made soft mount that I made. I had to built a nose ring box from c.f. covered spruce stringers and the put shear webbing in between the stringers. I then put 5 mil c.f. on the shear webbing.
It was a bit of a trip getting it all lined up but I finally got it all set and its working great. I am running an S.T.2300 and Bisson muffler. The muffler presented a problem in that I could only use 3 stringers instead of 4. I think the c.f covering on all the componants was the trick. If you are going to try this with a 4 stroke I have heard that it is difficult to keep mufflers on them. PLus I dont think there is enough room in the cowling area for the head to rotate. But experiment and if it dont work just cut off the stringers and go back to the hard mount. So far so good with about 100 flights. The only problem I had was the nose ring screws vibrated loose on me once. A little locktite and no more problems. Very little vibration thru the rpm ranges other then the usual low idle pulses.
I will try to get some pics othe the setup if anyone is interested.
