RE: DHC-2 Beaver
The Saito FG36 pulls this plane up at about a 45 degree angle no problem.
It does, however, need an electric starter to get it going the first time of the day.
After that, there's enough fuel in the carb to hand start after 2 or 3 flips
15 minute flights use maybe 6 to 7 ounces of gas.
20-8 APC turns at 7800 RPM on the ground
