Heli Head for cowled engine?
I recently bent a con rod for my os 46 fx. I am getting the replacement, and I noticed that a heli head is only $30. This engline is cowled with about 3/4 inch of head above the cowl, and is running a MCM, with 11-7 prop, so the load is quite high. Should I use a heli head for this to keep temps down?
