Hi, fellow rotary enthusiasts....just an update on my 13b powered SQ2000....Taxi testing at the airport have been very encouraging. Acceleration is very good. Got to rotation speed and lifted the nose at approximately 1000 feet of takeoff roll. Engine starts within one or two blades every time. Idle speed is: engine speed 800 rpm, with a prop speed of around 400 rpm's. (2.17:1 reduction ratio). After 4 taxi runs and aborted takeoff runs, the oil temp got up to 185 degrees. Oil temp was lower, but unfortunately I failed to write it down and forgot. I believe it was around 160 or 165 on the oil temp. Outside air temp was 75 degrees.
I have the Microtech ECU, and I am starting to become more familiar with it. I never actually did anything to it, as the engine fired up first blade after hooking up the ECU. I finally read the instructions on adjusting the mixture, and by leaning it 10 percent, it smoothed right out. I find a slight stumble when going from 800 rpm's to around 1000 rpm's, but then it really gets smooth. So happy I have a rotary instead of a Lycoming. Just an ignition switch, starter button and a throttle. (Did I mention I like things simple)?
One thing I did not like about the factory SQ2000 was it's ugly, draggy cowling. I installed a cowling from a Velocity, and it is obvious even to a non-pilot that it has been aerodynamically improved. No more unsightly bumps in the cowling, just a streamlined, low drag improvement.
Just waiting for the registration to come back from the FAA so I can have the DAR inspection, then it's time to fly. Thanks so much to all who shared their information and experiences to help me put this thing together. Paul Conner, 13b powered SQ2000 in Mobile, AL
