ENGINE
The prototype used the Quadra Q42. A Zenoah G-38 is also a good choice
for the following reasons; both have rear exhaust, both have good factory
mufflers and both fit inside conveniently. A Zenoah G-45 is recommended
for flyers that would like more vertical performance and higher speed.
The best choice for all out performance is the DA-50 swinging a 3-blade
prop.
Note: The plastic extension on the Q42 carb has to be trimmed to clear fuse
side.
Note: A simply way to prime the engine is to install a 1/8” dia. tube through
the fuse centered on the carb inlet. With 1/4” of the protruding outside, it is
a simple matter to prime with a syringe.
Note: Make your test flights without the cowl to insure adequate cooling.
After engine is broken-in experiment with the cowl cooling situation.
