A 20cc engine is suitable for many entry-level models. Therefore, it is welcomed by many model hobbyists.
For a 20cc engine, it is recommended to use a 16×8 Nylon/plastic 2 blade propeller.
It should be noted that the gap size between the 20cc carburetor and the firewall is very small, so a larger hole needs to be drilled on the firewall facing the choke to ensure that the engine has sufficient air intake. Otherwise, it may be due to insufficient engine power and low engine speed.
