I actualy did tape the bottom right after i took the picture

I do have a problem with the paint though , when flying in damp weather the paint have a tendency to peal of , specialy when landing in high grass , the paint i used is "fascolor waterbased paint" , could i use a clear coat or does that melt the foam ?
i think "fascolor" makes a water based clear coat but wouldent the problem remain if i used that ?

this is a bit off topic i apologize

I believe straight acrylic paints (especially the cheapo craft paints) will probably peel or chip off of the depron if used on any large areas without a seal coat.

I've painted straight on with Krylon Fusion. You do have to be careful because it will eat the foam. The trick is to apply light coats. It works well and adheres well.

It is often recommended to wipe the pieces of depron down with alcohol before painting or gluing to remove the release agent from the manufacturing process. Others "prime" the depron with minwax clear polycrylic before painting. I used a finish coat of the minwax poly on the bottom of mine to protect the paint and decals...so far so good.

Yes, you can clearcoat it to protect it, but you must use Polycrylic from Minwax. It's water-based so it won't eat the foam. It comes in the spray can or you can get the pint and brush it on.

This also gives it a hard shell that protects the foam as well.

Since you are in Sweden, I'm not sure what products are available to you. But what you want is a water-based polyurethane or polycrylic as a clear coat. You may have to go to a hardware store and ask, but you should be able to find something.

Look at the very start of this thread as well, on the first page someone built a wee raptor... looks nice.
About paint, I personally would never use paint on any material for rc planes, ever again, it just can't compete with covering film, most covering films are lighter anyway... I would recommend covering depron with a low heat film (eg. solar film) it makes it very hard to snap if covered properly! But if you want to go really light I guess dye is your best option.

So the guys are out with their Me109's , P51's and Corsairs and they are QUITE !

I drag out my F22 to go mix it up with them and what a racket !

I presume it's due to the prop in slot.

Has anyone figured out a way to quiet this effect down ?

Cut the slot in a bowtie shape. That's about it. Reduces the noise a little, but not a lot.

I like the noise. It lets everyone know I'm in the air!
