Very nice model of a relatively forgotten type, look forward to seeing photos of the finished thing - and a vid perhaps ?

I have just done the first full assembly and control check on the MU28. Following the balance check I have calculated that I need 402gm of lead in the nose to get the CG where the calculations say it should be. With a bit of luck the maiden flight should be in the next few days, weather permitting.

Not sure about that 2gms, Brian, maybe 403 to be on the safe side ;)

Don't worry Chris, I cast the nose weight 100gm light but insert a bolt in the casting. I then cut a couple of 50gm slabs which bolt into place so that I can reduce or increase the nose weight after flying. Cunning, Huh?
Only semi scale Cliff, no retract - only a fixed wheel and fairing. No sustainer however, that would be a step toooo far! :D :D :D :D

The MU28 maiden happened this afternoon and I would like to say that it was totally uneventful, but it wasn’t. Launched into a fresh 15mph wind on my home slope it stuck its nose in the air almost to the point of stall. An application of down elevator saw it try to bury itself in the front of the slope. The following 10 minutes saw constant repeats of this behaviour before I eventual managed to get it back on the ground. The CG was waaaaaaaay too far rearward and the flight was almost uncontrollable.
When I got it home, and after changing my soiled undergarments, I checked my measurements and calculations and discovered that the CG was 20mm aft of the rearmost safe position (well I am getting on a bit and the brain is not what it once was). I did the maths again and cut a few lead disks which were bolted into the nose which gave a CG position a full 45mm further forward.
Once back up the hill the MU was now flying about quite happily in the manner that I had expected. Hey Ho, every day is a learning experience!
Brian.

I finished the Condor 2 weeks ago, did the maiden this morning. Also realized I'd not posted a photo of the previous build, a 1/3 Swallow from the SSUK free plan.

Not a build but a revamp. John watkins built jaskolka built in 1988.
