RE: RCGF Engines
Another satisfied 26 customer reporting in. Ultra RC Katana maidened today after only one tankful of gas on the ground. The Kat weighs in at about 10 lbs 80z weight. Getting about 7350 on a Zinger 18x6 that I cut down to 17.25". Dependable idle down to 1500 or so and starts within a few flips. Even at this early stage hovering is posible with a little power left for pullot. Run-time and a better prop should make this agile little plane a 3D beast (at least way more capable than the pilot).
The only mods made to the engine was flipping the carb over for my setup and soldering the hole in the choke plate shut to help the starting prime.
