RE: New .90 gas engine (15cc)
Well we redid the tank today and hope to fly it again tomorrow. With the 15x6prop its running about 8000. The transition is good but at full throttle it does fluctuate from 7800-8300. Its got a good idle and has power all the way though. Yesterday when it would stall in flight it would slowly start to loose power. We richened it up 2x and didnt matter and she still would dead stick. Then when we tested it on the ground it would run great. Each time it stalled in flight it was in level flight at full throttle.
