After 4 toranados, 50-60 mph winds, rain, floods etc over the past 2 weeks the weather cleared to a bright 86 degrees with 2-5 mph winds this past Saturday
Engine: CRRCpro GF26I 26cc on 87 gasoline with 32:1 Penzoil Air cooled oil Prop used: Hawk 16X8 (looks like XOAR)
Airplane: Sea Gull
Laser 200 wing span 69" Wing Area 735 sq in
All Up Weight: 9 Lbs 15.6 oz (no fuel)
Arrived at the field and proceded tostart up the GF26I as usual on my test stand. Turned on receiver, cracked throttle just above idle, choked the carb and flipped 9-10 times with ignition off. Opened choke, turned on ignition flipped 4-5 times and engined started up but would not rev up to full
rpm even after a few minutes warm up. NOTE this is first time I attemped to run the engine with the cowl on. Since I didn't put any carb adjustment holes in the cowl yet , I had to remove the cowl to adjust the carb.
With the cowl off I again choked the carb and this time fliped 4-5 times with ignition off. Turned off choke, turned on ignition and fliped 2 or 3 times and it started right up and idled great. Advanced the throttle to wide open and engined reved up to high rpm.
Prefight checked all controls and taxied out. Took off and the engine died about 15 ft high. It sounded lean as it was starting to climb out.
Brought back and richend up the low end and the re peaked the high end. Took off again and this time engine ran good except for a little surge in low end. Flew out almost whole tank of fuel and landed . The engine had plenty of power. Vertical was good for my state of engine tune. Cruise was about 1/8 throttle. Plane handled very nice with this engine.
It appeas my optimum test stand tuning for the best idle and high end rpm left the carb on the lean side so much so that it would not run correctly when I installed the cowl. Then, my field retune was on the rich side and needs to be tweeked a little more leaner.
Sorry i didn't get any video. Just mangaged a couple snap shots. Next week end ( weather permitting as stroms are back today) I will fly again after retuning with the cowl on and switch to a XOAR 17X6 and get some video.
