Hey Cap, Francis Person and I flew that .46 on an RCM 40 trainer, we came to the conclusion that there is a fuel tank issue to deal with but while the tank was full it flew and ran quite well. I think a smaller tank will be the fix. We also flew my Sig Rascal 40 with an inverted PAW 40 turning a 12x6 three blade a 8,200, what a pleasant surprise, it leapt of the runway in about 4 feet and flies like it is on rails, the PAW ran flawlessly, my first inverted Diesel. We also flew his Goldberg Tiger 60 with a Fox Eagle 60 and Davis Diesel head. It would make very long verticle runs, all in all we had a great Diesel day. I greatly appreciated his invitation and hospitality. These were also my first ever flights off of asphalt and DCRC.
