A fellow BRCF member is building his right now and told me today that he is going to put in some right-thrust.
He says space is so tight, he may have to drill the engine mounting holes offset a little.
He said somthing about clamping the mounts together and sanding down the bases on a belt-sander.?.
I'm using a TT Pro-46 and there isn't much room. The mounts are <1 mm from the cheeks.
My plane is tail heavy and needs some weight on the left wing-tip, but it flys just fine.. (Of course, I'm a newbie and wouldn't know the difference)
I didn't have to do much trimming today, just a little back stick for slow flying. I'm only flying 10 min flights so far.
