Flapjack,
Carefull with those TT .36s. I used a pair on mine and couldnt put a big enough prop on to run them at a reasonable rpm. Didnt even think of 3 blade till the damage was done. But MAN, what a time I had with them. That twinstar would rotate 90 deg and go unlimited verticle as far as I wanted and was a real speed demon. Real crowd pleaser. I tacked them at around 14k rpm. Wore them out in about a season and a half. They still run individually, just not synced very well. Had to strengthen a lot of parts, mainly glassed the wing center section with 2 oz glass top and bottom and triangle stock on the firewall. Dual aileron servos also. Made a huge difference. Got about 9 minutes flying time on those 4 oz tanks. I set my timer for 8 minutes. I knew I had 1 minute to get down before the first engine ran out of fuel. You'll love it. But alas, think I'll try some GMS .32's next. Anybody have a comment?
