We offer custom-made wooden propellers for the T-27 Tucano 20cc Juniaer (sold separately). Always consult
the engine instruction manual to decide on the size and pitch of a propeller and consider the desired
performance according to the characteristics of your model airplane. 2 blade propellers are ideal for engine
break-in and flight tests, as they provide higher RPM and greater speed of response to engine acceleration,
while 3 blade propellers provide lower RPM, being very suitable for scale models, however, they present a lower
speed of response to engine acceleration.
The JC Super Props are factory balanced, painted and varnished, contributing to the good performance and
scale visual of your T-27 Tucano 20cc Juniaer.
Be sure to check the propeller balance to be used, always check the propeller for cracks or signs of fatigue
before use and check the general tightness of the spinner/propeller assembly to the engine.
