When I bought my Thermik Excel, it had already been badly bodged. There are a few areas that need some pretty severe fixing. It was cheap though The v-tail servo shoulders had been mounted on the top skin of the fuselage a foot from the tailplane, with the body of the servos hanging inside the fus. As it is now an electric model, the original place for the servos is taken up with batteries. So the obvious place to put some servos now, is in the tailplane surfaces themselves. This work has started in earnest (at last, so some good is coming of the poor weather / short days / dark evenings) and is progressing nicely. However, I don't yet have a plan in place for dealing with the two servo-shaped holes a foot from the tailplane. I suppose it might be possible to roll some 1/64" ply and cyano it in place inside the fus, but what should I use as a filler (to get the repair near invisible) if I can do that? Thanks in advance, Jef

Hi Kev
No the fuselage is a glass / carbon unit, if it were balsa I would not have a problem with re-sheeting / replanking it, or letting in a repair patch, and sanding it to a virtually invisible repair.
Sorry for the ambiguous previous post, I should post a pic of the fus really. Maybe tomorrow.
Thanks for the links. Will visit my brother in law on Friday (he manages some motor spares shops).
Have had an idea that will camouflage the repair, while typing this!
Thanks ever so much for your help!!
Jef

Have now mounted some different elevator servos in the tailplane of the Thermik Excel and flew it this afternoon (noted a major improvement in control - the 270mm-ish pushrods rigidity was very poor, so the trim was constantly changing previously!). It had occurred to me, that the holes in the fus would make a great place to access the plugs and sockets for the v-tail servos, so instead of filling and painting (and we all know what that would have ended up looking like) I popped some heat shrink on the plugs and sockets for security then made a tapered rolled (0.4mm) ply hatch and covered that with hologram film.
