RE: GSP Spitfire ARF build
Hgiles,
My humble apologies, you are of course quite correct. The review plane did indeed have a YS91FS NOT an RCV. I was thinking of the GSP Corsair review, which is still in its box in my garage waiting for me to clear the building table (Flair Giles 202 3D).
Looking at the video clips of the review Spit, especially the take-off, it seems that the .91 had plenty of power. Although a 1.20 would give you some reserve. Mine will do big lazy loops, which I doubt would be possible with a .91 (somebody prove me wrong here)....
