Make a Sliding Warbird Canopy

Make a Sliding Warbird Canopy

Many scale modelers simply can’t leave well enough alone. They often find ways to improve their scale projects. With the VQ Warbirds  Corsair ARF as a base model, A complete makeover to add lots of details is fun, but to kick it up a notch, a sliding canopy is one of the several sub projects that add life to the model warbird.


Here’s the Starting Point of the ARF Corsair

The Corsair comes with a molded-in floor allowing for only a pilot bust but I cut it away to installed a full-depth depth cockpit. I used the parts from a Ty’s Models cockpit kit, available from VQ Warbirds, to add a little extra detail to Pappy’s “office.” With all that taken care of, it was time to work on the canopy.


I felt it was a shame to hide my scale Pappy under a full canopy so for this project I wanted the canopy to be functional. In the past I have only ever made canopies open manually, but for the Corsair, I went the extra mile and make the canopy open with my transmitter.

The canopy alone is very flimsy and brittle and running it under warm water before cutting helps ease trimming. I wasn’t confident that it would hold up so I ordered a replacement from VQ Warbirds which is identical in size and shape. I needed to stiffen the canopy frame so it would hold its shape while opening and closing. Using the original, un-cut ESM canopy, I taped it to the fuselage and made a simple external balsa frame to keep the canopy’s shape once I removed it from the fuselage.

I then removed the balsa cradle and canopy from the fuselage and sprayed the inside with some universal mold release. I then laid in two layers of carbon fiber cloth and allowed the epoxy to cure overnight. After popping it out of the canopy, it was trimmed to shape and became the perfect internal frame for my sliding canopy.


A little spray of mold release inside the canopy prevents the layup from sticking in place.


After the resin cures, the carbon fiber molding pops right out.


Nice and smooth and it fits the canopy shape perfectly.

For the guide rails, I used some slotted square brass rails and carefully installed them in the fuselage sides and along the inside edge of the cockpit opening. Ball links are used to capture canopy inside the rail and allows it to move with the use of a single, long-stroke air cylinder located forward of the instrument panel.

This arrangement gives a “push to open” and a “pull to close” operation. I cut the carbon fiber frame to shape with a Moto-Tool and a cut-off disc and then I glued the clear canopy to the inside of the frame. The canopy be removed from the rails by unscrewing the ball links which pass through the frames.


If I had more channels on my transmitter I’d put the canopy function on its own switch.  At the time I built the model, I only had an 8-channel radio so I slaved the canopy function off the flap channel with a Y-harness.

I set it up so canopy does not open during landings (with one notch of flaps dialed in.) The model doesn’t need full flap to land. After landing I add another notch of flaps and the canopy sides open. The flaps do move down a little bit more but it only on the ground and does not affect anything else. With a 10-channel radio, it would be simple to assign the canopy function to its own channel and open it on command.


Which way to the front!?

Having this bit of animation added to any scale plane greatly increases it realism and sends the “Wow Factor” right off the charts. For a little bit of work, you get a lot of attention. Give it a try, you’re buddies will be amazed!

Doesn’t look like an ARF anymore! Weathering helps a lot too!

  1. Zigi RC sells Phoenix 60cc Corsair – Sliding canopy and retracts included.

    1. Yes, i’m sure, but its more rewarding when you create,Versus buy. An entire generation seems to respond with a collective…”huh”?

      Okay, there have to be a few people under 40 that still build?

      If you didn’t build it, its really just kind of a toy?

  2. Nice job Sean.

  3. Amazing work.

  4. Nice little engineering job Sean! That used to be more common in the hobby…

    I may actually apply your ideas on a blow up of an old Corsair plan from .60 glow to 60cc gasoline size!

    While you’re at it, how ‘bout some help for all on creating a plug for a canopy different from original. My Corsair plan is “bubble canopy” and I’ll need to create a plug for vacuum forming the “Birdcage” variant.

    Ought to be interesting?

  5. I’ve read all the descriptions and processes which has my attention but for some reason none of the pictures are displayed. Do you have this on a different website or URL? I’m very interested in seeing your work.
