Every time I have tried a diverter, I've either a loss of power or had an engine that would not run reliably, or both.
If I'm flying glow, I'll take the clean up over the diverter. removing the muffler has always increased the power on the engines I was using, but at the cost of a higher noise level.
same here, most of the people at my field who have deadsticks....run those...once we take them off.....no problems. some engines run just fine with a small rpm loss, most dont.
despite the fast supertiger engines have a boat anchor of a muffler they are easy to adjust so you dont get slime all over your plane
