RE: MOKI RADIAL Care and Maintenence
I've made baffles out of formica and have not had any issues such as cracking or getting out of shape. They're wedge shaped of course and fit in front of the exhaust pipes. I attach them with stainless steel aircraft safety wire wrapped once around each cylinder at the top and bottom through drilled holes. Simple and effective although I speak shooting from the hip as I've not taken temp readings with and without. I figure it can't hurt though. My engine is mounted in a loosely cowled 30-% Waco and overheating has not been an issue for me.
Heat can be a problem with these engines I've been told. I remember seeing Dino and the FW 190 that had a cooling fan in the cowl. It made more heat due to the energy required to turn it! Full scale planes almost always use baffles. Mitch
