Neil has been hard at work getting the wings sorted out.

He has bull-nosed all the surfaces, made the corresponding trenches in the wing and together we glassed the radius to hold the skins together and give the hinges a little better purchase. He has done a really nice job of getting the fit just right.

We cut out the hinges from a material that is sold as wet wall sheet. It is a baker-light style base with an epoxy or plastic coating. as strong as circuit board, but much nicer to machine.

In the meantime, I have painted the fuse and started to mount all the items. Tail feathers are mounted with the tailplane magnets holding on like troopers. I have redone the throttle linkage to convert it to a pull rather than push action... its just more positive.

Hi Henryk and team,

Almost done with the SA Pawnee.

Starting to look the part, teh plug in tails on yours us a great idea Henryk. You say you have magnets holding them on? That sounds brilliant.

Must try that myself.

Cheers

We have had a bit of an update - a change of heart!

The new DA100L has gone in without a hitch - nice motor!

Another long evening and some good results.

The new motor is all plumbed and all the wiring loom is ready. I also managed to cut some vinyl tonight and get a start on the decals... a bit more still but almost there

Neil has done some mighty nice work on the wings - servos are now mounted, worked out the linkages and all holes cut ready for gluing after the covering is done.

A little tidy-up and filling, then covering.

Not much left!

undercarriage arrived today - not exactly what was expected - but will do the job

that now means lots to do tonight with axles, hubs and mounts to make - and possibly a motor run tomorrow???
