I am currently building a BB Diamond demon which features an undercambered wing. The recommended covering is Solartex but how do you secure it to an undercambered wing section without it pulling off when heat shrunk?? Any suggestions gratefully received.
than usual. Having completed the covering, I then give the Tx 2 x 50/50 coats of dope - which seems to help it keep its shape. CheersSteve

The knack is to iron the Tex to the undercambered part of the ribs first, using a cloth to make sure the Tex is glued to the rib as it cools. Then work along the ribs to the leading and trailing edges, again using the cloth. Then do the outlines then finally the rib bays. Be careful not to get too much heat on the ribs though or the adhesive may release the fabric. If it does, simply heat the the rib area again and reapply using the cloth. I've done lots of undercambered wings and never had to use any other method, unless of course real rib stitching was called for.Ian.
why would you want to dope your transmitter ??
This is all very encouraging. I've always chickened out of using 'tex or film on undercambered wings in the past and put up with tissue puncturing at the least excuse or the time and mess/smell of nylon. Next time. I'll take the plunge.Mike
