Today I first started my sj.91 with torque muffler,after about 1 liter of fuel(5%) the engine made 12.1k with an apc 12/8,the engine is also quite noisy but not these is the problem: because the end of these huge muffler is ver near to the wing's L.E. I nstalled a du-bro exaust diverter secured with a plastic tie zap, what happened? after 5 seconds a full military the ex. diverter is blown away and the (very )hot gases warm the monokote tht covers the wing,I also noticed that without the ex diverter the engine is more noisy. the question is :how can I secure the ex diverter to the muffler(cyano?)
