I would like to know what turbine would be a good match for the Mark frankle Skyray , and some good pictures of them.

I think a P80 range should be good for it, here is the website:

Is it still available?

Hello guys
I have a Skyray, it is not the Frankel but the Liebetrau (no more in production).
It is the same scale that the Frankel.
I fly it with a P120, it is good with it, so you had some reserve. [8D]

Go with a P 120 sized thats is what Mark used to push his around. Mark might even have one or two kits in the shop.

I have a kit now, and have a new Rti 2800 that I could install.

He did the last time I was over there. Shoot him an email, he's pretty quick to respond.
