You are right its rougher than anything I would want to be in the air with for long. Generally clears up after a few seconds - no problems on warming mornings. It does sound like you could have an injector problem. I had one that stuck open intermittently and about drove me nuts over three months of trying to solve identify the problem. Boy, wish I could make a similar weight claim about my lead sled. I came in about 120 lbs over the Van's average for an Rv-6A - although I have seen those that do weigh more than mine. 44 lbs of batteries probably contributed to that a bit, heavier than necessary wiring, motor mount, exhaust system, AN-16 hoses, etc, etc. it adds up quickly. Hope you get the problem fixed soon.

My total empty weight (including approximately 1 gal of gas plus oil and coolant) is the same as Van's sample weight and balance number. I believe that is the number of their 9A with a 160 HP lyc. If that is the case then my weight is exceptionally good because the factory works hard to keep their weight to a minimum. The painted weight is 1072 and the CG is less than a ¼ inch aft of the sample. With 60 gal of gas and my 155 lbs fanny, the cg is still not too forward and I would probably always have some luggage if I'm loaded with fuel to push it aft to a better location. > > The bad news is that the run today still ran on one rotor for approximately 1.5 minutes. It is rough! When rotor 1 did fire up, I had to shut the secondary switch off to keep it running. This means that the injectors are running way too rich and it appears that rotor 1's primary is probably the culprit. Will pull the injectors tomorrow and see if I can determine anything, May just buy a new one and stick in that hole. The airplane is getting a real shake test when it is running on one rotor. Would be scary trying to stretch a glide by keeping one running! Don't think I will wait next time if it is only running on one rotor. > > Bernie > > >> Homepage: http://www.flyrotary.com/ > >> Archive: http://lancaironline.net/lists/flyrotary/List.html >
