Mono Nylon stabiliser legs.... Outrigger legs / Motor Gliders All outrigger legs on the Scheibe Motorfalke like SF 25C or on the Sperber type MG's like RF5 or RF4 the outrigger legs are shorter, so that the wings are dipping from one side to the others. I think it is good so that the wings are dipping, because when they are getting controllable, you will know that your baby is ready for take off. Always safe and happy flyings.

The intent was to match same to fuselage for purposes of rationalising feed-through sites for wiring and odd items. By the way, these and the other surfaces were beautifully finished by a local firm to a tough mirror finish. All was normal on the 30-minute trek back home, and we unloaded same onto brackets built to set them vertically (nose-down) prior to installing them. When we began the sequence, I noticed a discolouration on the port leading edge and discovered a smashed leading edge about two inches in diameter, right on the leading edge - right down into the blue foam. This corresponded to the position of the wing in the rubber strap (lined with bubble-wrap). I noted that the pip-pin for the strap structure hinge release sits dead-centre under the strap. Sure enough the strap was pure (?) rubber and I could stretch it downward with just my fist. There is no question that, given the odd bump neatly handled by the trailer, evolved into a surge of the wing down until the pip-pin punctured the wing. This is going to lead to at least a week's delay, in rebuilding the wing and then driving it about 70 miles on country roads to the now-retired re-finisher. He took the tools/fixtures with him to his home airport. So this is a belated warning: (a) reposition the clamp-folding pip-pin to another suitable site away from the wing leading edge, and (b) replace the rubbery slings with some (preferably white) rubber with cloth reinforcement to resist excess stretching. I'm still going to line same with bubble wrap as I have saved acres of it and it works. I will be canvassing McMaster-Carr and similar sources for same. If you are light years ahead of me and already possess same, please advise. All advice gratefully accepted.......

I might add my adventure here: The trailer i have has woven strings, from a material as used by lorries as strap-down. On my way to the painter i noticed in the mirror that a wing was moving around more then i would expect, so i stopped a few miles down the road. Then became clear that both wings had moved backward, and that there was only 2 inches of spar left in the clamps. It would not have taken very long anymore before a wing went flying! The wind force on the fairing, together with bouncing in the straps had been more then the friction of the otherwise tight clamps. Securing both spars with a rope around the aileron mechanism is really needed!

Mono Nylon stabiliser legs.... Bruno You are right about motor gliders and I used to think the short wing mon was the same but qyucker. IMHO its too quick to react with aileron so its better to have the outriggers firmly on the ground with the etunted wing Europa. Tinsfos as all glider pilots know.

Ferg Sorry to hear of your misfortune, you must be "gutted". Just for the record my wing carriers are made of spent conveyor belting lined with carpet attached by heavy duty upholstery glue. I don't tie the wings down but the carriers are about 12"/15" wide thereby spreading the load. However since my trailor weighs in, loaded, at about 3 tonnes and has a double axle linked weight transfer suspension nowt bounces! I do think though that to spread the load is very relevant since it reduces the psi point loading on the wing. They are also fixed laterally by the pip pins through the spar holes.

Turned crank a few times to keep things lubed. I took the cap off the cold air side of the turbo to feel a new turbo. In and out motion on the turbine was only a few thousands, but up and down motion was ~.016" at the turbine Pushing hard I can get the turbine to hit the housing. If 914 owners don't mind, please measure their up and down motion and if you can get the turbine to hit the housing and post results. Another request is for axial and radial limits for the Rotax 914 Turbo if someone knows. In all fairness up and down motion should be measured on the shaft between the hot and cold bearing, pushing just on the cold side, I suspect the cantilevered leverage is pushing the hot side of the shaft in the opposite direction. That said if all others have half what I do and can't get turbine to hit housing, I think I may have a problem and further investigation required. My 1983 Volvo Turbo had a Garrett turbo, oil cooled only, the turbine looked very similar and after many miles had less play than my new 914. Could not get turbine to hit housing. I have a 1992 745 Volvo turbo with 255K miles and a Mitsubishi water cooled turbo and play is way less than 1/2 of the 914. Can't get the turbine to hit the housing. Thx.
