100cc YAK DA 100 question
My DA 100 seems to be acting funny, performance seems very low and I was wondering if anyone had a problem with airflow with cutting out the cowl like the instructions state and using MTW-75 canistor mufflers. I opt for the 3 blade mezjik 25X12 prop with the cans and boy they are silent 
My RPMs start out around 5700 to 5600 and seem to drop off to about 5500 after about 2 mins of flight, almost like its to lean, but if I richen it there is no power. Its got me worried hope something is not wrong with my engine. Im getting 38 pounds of thrust, but my friends 3W with a 2 blade is getting 48 pounds. Any ideas?
