Default What kind of paint for my Canopy?

Hi:

I just got a clear canopy from Align. Now I would like to paint it. I know that most likely the paint will go inside, since the plastic is clear and it probably will act as protection for the paint. What type of paint to I need to paint this canopy and where could I get it?

Thank You.

I use the Tamiya lexan paint, normally sold for painting the inside of R/C car bodies. It bonds to the plastic without an undercoat and is quite flexible so doesn't crack or flake off (at least not so far).

I painted mine on the outside as I am too lazy to do it from the inside. I then used 3 coats of Tamiya clear coat after I applied the stickers.

Process:

1) Sand with 1200 wet+dry or grey scothbrite to remove all shine
2) Wash with mild soap to remove all dust and oil/grease from hands. Dry thoroughly.
3) Apply multiple light coats to build up the colour. No sanding between coats. Allow to dry 24hrs
4) Apply stickers. Allow to dry 24hrs
5) Apply 3 top coats, no sanding between coats. Allow to dry 24 hrs.

You let stickers dry for 24 hrs???????????????

And you are waiting a bit too long to apply the clear coat. 48hrs after color is quite a bit without scuffing it first. Lexan paint usually dries to the touch in 30 mins, and is cured within a few hours. You are far too patient LOL

Great looking canopy. Did you have to cut something from underneath the canopy? I noticed you cut a hole on the sides.

Also, I want to paint the inside, so the paint won't get scratch up. do I need to sand the inside first? or can I just wash the canopy and dry thoroughly before I apply the spray paint?

Thanks.

The white canopy is all I have ever worked on. It has grooves for those cutouts in the cheeks and under the chin. I don't think they are mandatory. They let some air flow through the canopy to help cool the battery/ESC. I'm not sure how effective or important that is. The chin cutout can also be used for getting access to the battery connector, depending upon your electrics layout and cable lengths.

I have never seen the clear canopy myself but I think that if the inside surface is shiny then the paint won't stick properly and it will need to be sanded. I guess at worst, if the inside paint job doesn't work out you can always do an outside paint job to cover it up. Painting from the inside does have the advantage of not getting outside scratches and having the natural gloss finish of the shiny plastic. I guess there is a small risk of scratches from the battery, cables/plugs or the mounting posts. Working with spray cans rather than an airbrush, I just don't have the skills or patience to paint on the inside, it's a rather small canopy after all.

If you end up painting from the outside on a clear canopy I imagine you will save paint if you put a white coat down (either on the inside or outside) to give a solid base for the colour. This isn't needed on the white or yellow canopies which are opaque anyway.

Be sure to post a photo back here when you are done so we can admire your work

Kenneth, it looks great.

How is the orietation of the blue canopy against the sky (or it is always cloudy in Mebourne). I'm going to try your painting system on the window section of my yellow canopy only with the blue flake. The yellow makes a huge difference on a cloudy day compared with the basic white + stickers.

I broke my original 1 year old canopy two weeks ago. I was going to paint it... and then there were too many pieces of it

It isn't good for clear canopies, but what works for me is the permanent marker approach.

First I color it in like my 3 year old daughter, then I go back and dab at it to remove all the streaks. Works lik a champ.

Cheeky bugger Orientation seems to be my biggest problem. It doesn't blend in to the sky at the distances I fly (< 30m). It's either a dark silhouette if against the light or sparkly blue with the light behind me. I try to always fly with the light behind me. Mosty though at the moment I tend to save the blue canopy for indoor use and fly my dayglo orange training canopy for outdoors.

I presume you are not going to cut out the windscreen section, just paint it, which should work fine. I used the Tamiya metallic blue. I don't think painting the smoky windscreen would work too well as it is so thin and flexible.

Cheeky??? At least didn't mention the wind or trees , oh. sorry...

I haven't cut out the canopy. I'll just paint it as you say (or use a marker). Especially now that I am throwing it around, I don't want to spend hours working on it to look pretty.... it still breaks...

They are home made from a design by Tonke. See this thread: http://helifreak.com/viewtopic.php?t=17877&highlight=

Note: Get his second set of plans from near the end of the thread, they have a correction.

Photos, well here it is. Still has original tail feathers from 12 months ago. I'll get the yellow set this week. Almost a stock XL HDE + 450TH.

It loops well Kenneth :glasses2:

Looks good Peter. Is that with a clearcoat or just au naturale ?

I see you chose not to cut out the cooling holes in the cheeks either. Is that an aesthetic choice, a functional one or just couldn't be bothered ?

Original tail feathers, now that's an achievement indeed. I gave up replacing mine. I have just the centre of a horizontal fin as the mounting point for the boom stay clamp and an aluminium-reinforced vertical fin that has survived many a tap on the ground now.
