OK, well after allot of personal turmoil I've finally returned to modeling and more specifically my 4 stroke experience. Stock TF SCORE and Saito .56, Master Airscrew 12-6 3 blade. this is the exact setup Mike Alimov let me fly at the Cleveland meet several years back. I got about 10 flight in yesterday with varied results. The airplane itself flys quite well and I did get a bit of trimming in but in all those flights I managed only 1 good run. I had started out with a 2 oz suction tank which no matter how I played I could not complete the pattern. I calculated the fuel consumption and ended up making a 3 1/3 oz tank. Even at that I could not quite finish the pattern, obviously something was wrong. So I decided I'd try muffler pressure and ended up with 8 minute plus runs so I presume my earlier issues were NV adjustment finis', I've never run a 4 stroke before and I'm still on the steep part of the learning curve. Still not running consistently I tried cleaning the NVA and spraybar and after that is when I got my on excellent run. The flight after that when I started it acted rich so I touched the needle lightly to lean it, not even 1/8 turn. Took off and about a half lap in it cleared its throat and really ran strong, and too lean to maneuver with. the last flight, richened back to the original position did the same thing. I am going back in and clean the fuel system and replace the fuel filter, if I could get back to that one run quality I could really start some serious practice.
