CRRC Pro 40 cc Engine and AMSOIL

The CRRC Pro 40cc engine was tested on a Cermark 1/4 Scale Pitts biplane. The all up weight came in at a bit over 12 lbs. Even with the smallest propeller the thrust to weight ratio was more than 1. Since the engine was still breaking in, I limited the flights to mild aerobatics and general pattern work.

As you can see on the video I am using a heavy arc welders glove to start the engine. Starting the engine is not hard, but you do need to exercise caution around the propeller. Choke the carburetor and turn the ignition on. The choke is applied by closing the throttle and pulling the choke lever on the carburetor. Flip the propeller until the engine "pops". Then move the throttle to un-click the choke and flip the propeller until the engine starts. Above 70 degrees the engine would often start in 1-2 flips. When it was colder (like in the video) the engine would require 5-6 flips. If you don't flip the propeller hard enough when starting, it may start backwards. If that happens, shut the ignition off and restart the engine.
