A friend mentioned that he had an old Multiplex ASW 22 sitting at his parents' house and I said that I would like to have a look at it, somehow it has ended up in my shed!!

It was in reasonable condition but has some problems that need fixing:
  • Wrinkly wing covering
  • Broken airbrake link pin
  • Hole in rudder
  • Elevator drive horn broken

The damage is mostly from house moving and storage and a little bit from flying. I've fixed the hole in the rudder and the broken elevator horn but the covering is defying all attempts to tighten back up (though it is looking better than it was).

I struggled for hours trying to fix the airbrake but in the end I pulled it out of the wing fairly neatly and will be installing new Graupner double paddle units. Update:These brakes were eventually fixed and used in another glider, see here for how I did it!

It has a central aileron servo in the fuselage and I wondered about fitting wing servos but I'm not confident that I could thread any wires through. The linkages are fairly slop free so I'm going to use a servo for each aileron as shown in the instructions for the Multiplex Alpina Magic (ASW 22 and Alpina Magic instructions are downloadable from MPX).

I think this will go nicely on the slope but it does have a belly hook, just wondering whether you can bungee launch a 4 kg, 4 metre span glider safely? Maybe with a headwind!! I don't do aerotowing yet but must have a go this year.

Cheers
