Hi Shannon and all....Finally screwed up my courage and trailered the plane over to my strip...did a few taxi runs in a nasty crosswind, and quit before I broke something....engines pulling good, but difficult to sync with one tach, and a lower sound, and me hard of hearing...I tried again about 7.30 in the evening...the wind had dropped a fair bit, but had swung from the w. to the n. still about 30 deg. off the runway....takeoff run longer than I expected..probably 200'...the field still fairly soft and uphill too, but a bit longer than the rotax's....climb out seemed good enough but the air was so rough and I was too busy flying, and trying to get the engines powered back to get a good handle on the real performance....it looked like maybe 43 mph at around 4200....I think I'm going to need trim tabs after all Shannon....flys a bit more nose heavy than before, and I'm going to adjust the stick ahead to give me a bit more room on back stick when flairing...that landing was a lot heavier than I would have liked and you can see in the vid full up elevator....wind speed a lot less at ground level and I stalled it on...
It appears these motors are quite capable of powering the Lazair....my all up weight would be about 430 lbs. or so.....I'll get some more accurate performance figures down the road
Josh got a bit of video of the plane flying on his site....everhill69....
Cheers ......Pete
