Thanks for all this great information. I've been flying RC now for about 8 years or so. I am putting together a Super Star 120. The engine I have selected, so far that is, is the OS 1.60 FX. The engine is new.

I have been considering using a flex mount for this installation and have read your posts with interest.

I have read, on several different posts as well as other places on the net, about the nose rings. It may be real simple to most of you, but I am somewhat confused about how this is installed and how it works.

I presume that, being a nose ring, that it goes on the prop shaft or on the spinner. Is that correct? Or does it go on the Drive Washer? I've not seen one, so I am both interested in curious.

Thanks.

CGr.
