Yes Wiker, It certainly does look like that was the front runner maybe.

Bob, Yes going to build another fuse with E-Power. Hence the blue decals.

That would be my first E-Glider, so im leaving it for now.

RE the stripes, i like them, its a european look. Ill lay them on and see how they look. I wont stripe the underside. I like a few high vis decals and i think the Alpina will need it as these models have a tendency to be flown in strange orientations...

Wiker, They are even better in the flesh. The quality is outstanding.

Heres her big sister the 'Vortex'. 5m and 6.75kg.

Wilker.......I had just tried to both slightly inward and then outward. Didn't notice much improvement but thanks I'll try bending the rear one like that. Never heard of the Condor. Another beautiful bird. Multiplex sure knew how to make'em !!! Love the MULTIPOXY fuse. You wouldn't happen to have a link for the auto lock stab mechanism, would you ? I've looked all over and can't find it.

Jimbo.......I agree but the vis strips IMHO should be on the bottom. When you get around to it, you'll LOVE the electro version !!!

Iíve looked through my boxes. If only I could find the set I bought, but no

Just google: multiplex 725137

http://www.modelmaniacsonline.co.uk/...Pendel+Lock%29
http://www.hobbydirekt.de/Pendel-Loc...137::1986.html

Came across a couple of links that might give some ideas/inspiration to other solutions:

Bending the rod, it doesnít feel very secure, no, but seems to create enough friction to hold the tail in place. After landing, my tail panels have never been more that maybe 1-2 mm out, and I suspect it happens at touchdown. A more secure solution would make me feel a bit more comfortable though.

I started on the wing install. Should take a few days at least. 6 servos to install which are all slightly too big for the bays. Oh well, i suppose i could of installed something skinny instead and made the job easier but i should get them in.

Regarding the covering, i was chatting to a very experienced local modeller about preparation before covering with oracover.

He mentioned sanding sealer and dope, with a preference for dope as this will dry stiff and provide some additional rigidity and crush resistance (albeit with the caveat that getting any on the foam will screw things up big time).

well I tried ( A LOT ) searching for it w/ google, but to no avail. Looks like they are no longer in production and I only found one place that had them, but they don't ship to US. WTH do T/D owners do that have a full flying stab?

I can't comment on the Alpina but on aeroplanes of mine that feature such a tailplane, the rear joiner (the one that moves in a radial slot) is a smaller dia to the front (pivot) one. This smaller joiner is glued into one tailplane half and the other end has a tiny bend in it (last 15ish mm). Don't go overboard on the bend - you don't need much at all. When I used to do such things, this proved more than adequate for big winch launches etc.

HTH,

S

There's a reason why these are so scarce: lack of demand. There are millions of models flying with AMT's held in place by simple friction (not even bends in the rods) with no problems ever. In fact, if you can shake a normally-mounted tailplane half free during flight, I'll eat my Alpina.

Soldered the other wing connectors. Wow was that tricky.

Also Had a look at the film hinges, again another tricky job. Manual says use a circular cutting disk, i made do with a craft knife.

RE Tailplane joiner, there is a clip on the Pro which secures the two tailplanes halves together.

Wing Install

Well ive done the 'First fix', ie a dry run of all the servos. Not quite sure how i managed to shoehorn those big hitec 5245s in there, but they all fit and the tops fit nicely. It was quite a squeeze. But the wings were thick enough.

The Hs85s on the brakes also fitted ok, i removed some foam to get them to fix.

Next step is the epoxy all the cases/mounting and loom wires in place.

I will also add a little glass in the bottom of each tray to give a little extra strength.

Heres the pic.
