RE: GSP Spitfire ARF build
My maiden was a bit hairy too!! The cheap plastic throttle connector broke. Had to buzz around at full chat for 15 mins while I ran the tank dry. Thankfully I made sure I had enough height as the engine cut. So my maiden was a dead-stick too. Not what you want with a new bird - it's hair raising enough as it is.
Hgiles, you said in the initial post that you were thinking of a .91 FS as the review had a .91. Well don't forget that the review plain had an RCV .91 which is a geared motor (2:1) I just think a standard .91 is not enough motor for this baby. I have an ASP1.20FS which has plenty of grunt but I would say it's only adequate for a 10.5lb Spit. Also you want to throw a reasonable size prop (15" or 16") I first flew mine with a 16x8 - flew great and looked good too. One of our members uses a 14x7 3-blader and it just looks too small.
Just my opinion - please feel free to "shoot me down"
