Hi guys

I'm tarting up one of my old vintage free flight models and sticking some RC in it at the same time.

Got any tips for removing old dope tissue.

I've done the fuselage and tailplane but I still have the wing to do and I'm a bit worried about taking off too much of the old balsa profile.

Thanks

Bob

Try brushing cellulose thinners on to the ribs & areas where it is stuck. If it was put on using dope rather than tissue paste it should work.

Agree with that . If its pasted on then get out the sandpaper :)

It was definately doped on so I'll give the thinners a shot.

This is what it looks like at the moment....pretty sorry for itself.

The model is a pretty ugly beast, called Wedgy but it was always a good flyer as free flight.

I'll post more pictures later

Thanks guys

Bob

Ok

I finally got the tissue off the wing! What a pain that was! in the end I opted for sanding the top surface and using thinners on the under camber so I did not ruin the profile too much.

I've since covered the tail with Litespan. I must say this is a very impressive product. I wish it was around when I was in my hay day.

I'm a bit concerned about getting the Litespan to stick to the under camber of the wing. Anyway I was doing a bit of surfing to see if others had problems, lo and behold I came across PhilF chatting on a forum about just that :)

So I'm going to try a couple of panels using PVA and Clearcoat see what the options come up like. I'm not too concerned with fuel proofing the model as I 'm going to stick a brushless motor in it ( see picture).

Regards

Bob

Hi guys

I've finally finished the refurbishment. In the end it was all down to the sandpaper!

I opted to fit electric in it and Radio assist...all cheepies from Giant Cod.

The new litespan covering is pretty good, all I have to do now is see if the new motor can get it airborne.


The mount btw was made on my rotary table on my milling machine which meant I did not have to change much in the plane.
