the fiberglass fuselage has been snapped in half, not sure if it is repairable.

we did this owd bird at length in chat last night, its not a YT bird,(me thinks i should know ) but it IS a rarer beast, its a Turman models ME109, early kit designed by Roy Scott, great flyer, and the first super scale kit offered to the public, in its day, it was a BIGGUN, being 72inch, i think its well worth restoration, BUT, it has to be kept light, we discussed the way forward last night, the fuzz is polyester, i cannot remember if it is woven, or chopped mat, any input would be good, as said, the damage is around the CG, if there is enough mating parts there, then restoration is doable, the YT canopy will fit, the cowls there, the retracts are there, the wing is in one piece, What do you reckon? should Tony go for it? i have sent Tony a piccy of a flying one, something to salivate over, one thing, super glue will not work, but epoxy will,

Here are the pics as it stands.

air retracts.




flaps and ailerons work via bellcranks and single servo's in the wing center.
the wing looks to be built up and skinned with fiberglass sheet, lots of detail.




Hollow glass fuselage, tailplane and fin are also fiberglass (i think)
the break is clean with no bits missing.
no wooden formers left in the center of the fuse and the steerable tail wheel former has come unglued.
pull pull wires on the rudder and elevator are broken.

more info needed please.

Cracking looking model but probably a challenge to fly

due to the varying wing sections, the stall was benign, Roy knew what he was about, its most important that the lateral balance of the model,once completed, is correct, its most difficult trait is keeping it straight on take off, the undercart is further apart from scale, but still care is needed with the take off roll, once up, she is a pussycat, how do i know? i flew one for a while, until offered silly money for it, before this, Ian Redshaw made one that gained silver at the model engineer contest, stitch it together Tony, but watch the weight as for the detail, you wont save it, apart from the fuz, the wing needs flatting, remove all rads, bumps and blisters, and treat it as a new build, if the wing is glassed, then it will flat back with wet& dry very nicely, go for it Tony, bit of history there

Thats e-poxy suggestion, as long as you can get it thin enough to penetrate the fibres, cant see a problem, for me, it would be wing skinning epoxy, with thin cloth, i also have another ingredient, carbon fibre dust, its the produce of turning carbon fibre, put it into wing skinning epoxy, and the strength is incredible, i will send Tony some, if he is good,

how about using a wing bandage with the thin epoxy they supply.


i am never good.

Wing bandage is tooooooo thick, soak up too much epoxy, if the fuz is chopped matt, then use chopped mat, if its woven cloth, then use that, but it must be thin, multiple layers are ok, small enough to cover the repair, then bigger, then bigger again, this reinforces the join, and spreads the load down the layers, use a single layer of thick stuff, or several same size of thin stuff, and you create a shear point,

and i know you are not good, so, go stand in the corner for the rest of the night

but would the wing bandage epoxy be ok to use.

i can get that and thin mat from rc world.

Dont think so, its a tad thick,

i have been informed that is is an "emile" flown by Franz Von Werra. ( the one that got away)
shot down in 1940 over kent.

i must get round to looking at the fuselage soon.

Looking at a fuselage would be great, NOT THE 2 HALVES, gerrit done,
