I'm building a small electric powered aerobatic Depron model- a first Depron endeavour by me- light- about 28" span. Don't want to leave it white. What lightweight coloured covering marterials/ paint can anyone suggest? Don't know/ think that Solarfil woud be suitable, due to heat considerations?

I believe most cover their depron (and similar) models with a frugal ( light ) application of water based rattle can paint. Stencils and such are used if you want it nice.

I've used water-based acrylic paint on all my depron models. It then gets a thin spray of enamel varnish to protect it -- matt, satin, or gloss depending on taste.

20150220_105650[917].jpgHi Tosh, This is a Hawker Seafury I drew up and built about 6 year ago, it has a balsa frame but the ribs and formers are depron . the whole plane apart from the cowl and the last part of the fuse. is covered with 1/8th depron. It is 48" span and there is only paint on the depron it is mixed from match pots of emulsion paint from Wilko, the white is the unpainted depron the black lettering is maker pen as is the roundels. At the moment it is in the process of being repaired at the front end after a transmitter fault .

All depends on how much work you want to put in and what kind of finish you want.

Their are lots of options.

This is a tiny light weight indoor model made of depron and just a bit of trim to add color iron on so-light from solor film.

As is this one.

Or if you like tissue and Poly c .

This one is also made of foam and over 5 ft wingspan.

Or how about standard Solor Film .

Or Paint it as other have suggested.

Thanks for that guys. It looks as though Solarfilm may be an option- presumably applied with a warmer than usual heat?

Solarfilm works well,

Clean first with a damp cloth and mild detergent so no greasy marks are on the surface let it dry.

Set the iron to warm you will find that the film will stick very well but do not overheat and have a cold damp cloth ready to cool the surface down after application and make sure when applying the film to the surface it is as flat as possible you will not be able to pull sags out with heat you will probable melt the foam underneath.

But with careful planning it can be done .

This of course does raise the question "Does the finish actually make it fly any better?"

Unless you are into really high speed (unlikely in Depron) there is a school of thought that says the 'all over' slightly dimpled surface improves the consistency of the air flow breakaway point so improving the stall characteristics.

Works for me.

^ Another school of thought is that light models fly better: everything that you add detracts from lightness.

Depends on what you want. Some have built large models, using depron, or similar, for much if them - and ended up with nicely finished models that are still incredibly light.

My question was not to make the the plane fly better!  Rather, a) to make it more attractive, and b) for visibility. But  I don't want to add too much extra weight!

Thanks for the interesting and usefull replies so far.

Just had a thought- has anyone used the coloured vinyls used for decorating white vans (I'm thinking of the likes of the Sky vans that are highly decorated.)

It is just the weight Tosh, and wingspan

You can do very little more to a 50grm model

Even at 100 grams you can struggle with weight

Over 48" span you can relax a little

Thanks Dennis,

I'm looking partial trim for a 900mm depron plane, about 350g?
