Invertmart - thanks very much for your post and pictures! What a superb machine . . . bet it sounds as good as it looks. Any more pictures and maybe video (with sound) ?Over here in the UK I have just found a LHS who reckon they will be able to get me a UMS 7-77 in the next couple of weeks so the TF GS Corsair may be getting its power plant sooner rather than later. Will keep the forum posted. Thanks all! Dave
Here is the complete build thread:

And some videos:

Engine runs-working on getting the prop sized correctly:

The Second flight. This one was marginally better than the first flight. When i say marginally better, it had about 10mph more flying speed than the very first flight.

The Fourth Flight: This one is substantially better and essentially how the airplane is configured today. I did a slight bit of re-profiling of the prop tip to taper them more and got an extra 100rpm more compared to what is in this video.
