    Thanks Phil, Up to now I have used a brush! Can you recommend an air brush kit not toooo expensive! What sort of air supply? Mike.

    I have now completed the fuselage covering with tissue bonded with PolyC see pics. Next question do I continue using PolyC to fill the tissue grain or use 50/50 none shrink dope/thinners. Regards, Mike.

    Hi Martin, got round the problem by doing the edges first leaving a 10mm return, then cutting the 'blank' slightly smaller. I usually use thinned PVA but had 500ml of PolyC in stock. The trick is to insure tissue to be stuck down is not coated with PolyC by accident. The result seems quite good, but have noticed it takes a long time to dry certainly not the 20mins quoted. I use dope after the tissue is bonded. I could never get on with bonding down wet tissue with dope. Have noticed the scalpel blades loose their edge quickly cutting tissue!! Mike.

    Hi all, Help with PolyC and tissue application I am covering the Tucano airframe with tissue and PolyC. No problems with application to flat surfaces but to get a bond around the edges is proving difficult. What I am finding is once the tissue is coated at the edges and dried it does not like to bond around the edge. I have to apply around the edge first with a strip then apply tissue onto the flat as a second operation. Hope this makes sense!! Any way around this problem? Mike.

    The airframe has received 1 coat of 50/50 sanding sealer and 1 coat of 50/50 dope, before moving on to the next stage I will conduct a pull test using Solarfilm silver on a sample treated as above and a further sample on bare wood. Martin what are your concerns? I am a little concerned to apply a water based adhesive (PVA 50/50) directly on to large area of untreated balsa given the distortion risk. I use 50/50 PVA (brush through) to bond tissue then several coats of thinned dope before the final acrylic finish. Nose wheel, I see that this has a smaller diameter? Mike.

    Point taken BEB!! Martin I had not realised that these iron on films need to be applied to bare wood only. Thanks for that info - I will continue with tissue. It just goes to show how important these forum's are, we lesser experienced can tap into the knowledge of others who have a wealth of knowledge/experience. Mike.

    OK BEB - just contacted Solarfilm they say it contains an aluminium powder which 'may' affect radio signals, but not sure at 2.4GHz. They say best advised to put an antenna outside the airframe. - bit of a pain though. What is this Dawn Flyer? Mike.

    Hi BEB, Just one point, you state 'Solarfilm does affect radio signals' then you go on to say David 'He found it made no difference at all' bit confused here!! I have no problem with dope smell my shed is 17 miles from my partner's home!!. Have you rebuilt your Tucano? Mike.

    An interesting thought Martin, never thought of a composite solution - silver solarfilm on the flat panels and tissue on the complex shapes. one worry though with solarfilm the surface has to be 'prefect'. do you guys use an iron or hot ait gun to apply the film or both? I am Appling a sealing coat over the air frame comprising 50/50 sanding sealer rub down then a 50/50 coat of none shrink dope and final rub down, this provides a sealed surface to apply tissue using 50/50 PVA and water or silver solarfilm. Colin, I have had my fair share if warping on this particular project especially with the wing panels and that is just being left in the open for a couple of weeks!! Mike.

    Hi all, I am now in a position to cover the airframe (better late than never!!). I plan to use the Battle of Britain memorial flight colour scheme which means a paint job. As I see it (you master builders may differ) I have two routes - tissue and dope or fibre glass and PolyC. My preference is the tissue route because I have used this method many times. Some master builders on here have used the PolyC - I have the stuff but need to be convinced it is the better method. Your comments please. I am not a master builder so please be kind on the photo comments!!! Mike.
