Re: Russian or Chinese Radial on F24W?

'For those of you who are bringing a derelict back from the grave, the experimental route looks pretty good. In this day and age, its not like the experimental category limits the usefulness of the F24. In fact, it increases the safety of operation. If you’re a die-hard purist antiquer and you absolutely need a certified airplane, you’ll just have to be satisfied with a Ranger or a Warner, I guess. No problem with that. But if it comes down to keeping these things flying with round engines, the Russian radials are a good choice. If the original designers were around and had a choice to replace the Warner, I’d bet it would be the Russian radials.

Ditto. The engineering and FAA conformity requirements would not make it worth the effort for one or two airplanes. Installing a Ranger would be easy. It's already approved; all you need is a FAA Form 337 Major Alteration using the Type Certificate Data Sheet as approved data.

I did not think its feasible to transfer an aircraft with a standard type certificate to an experimental amateur-built certificate. Changing engines will not create an experimental homebuilt that passes the 51% rule. You could register it as Experimental — Research and Development for the purpose of creating an STC but could only operate it under stringent restrictions.
