This Gee Bee R-3 I'm building I expect to have for a long period of time. Well, maybe. Especially if I don't fly it. LL~
Yes I'm kidding.
Canopies sometimes take a beating over time, even when cleared with a good 2K auto clear. So, I'm thinking of having mine removable so I can refurbish it if need be. That is, simply replace it.
At 4.00 each, I purchased two canopies anyway, one for the fit then the second one that actually gets glued and finished in place.
Has anyone else done this? Yes, I have a few ideas, but I'm looking for other methods of easy attachment?
For those that don't know, here's a photo of an ARF R/C model that is like the model I'm building.
Thanks in advance.

I've never done it but maybe you could have a hole in the bottom of the fuselage so you can access a screw?

Not an answer but recently I was bored and read all the articles here
http://flyinglines.org/Scale.html
lots of red meat for a guy of your skills
Made me think perhaps a NON RC actuated/commanded, simple mechanical sliding canopy might be a reasonable effort to design in

The only removable canopy I've ever seen on a stunt model is here: http://www.outerzone.co.uk/plan_files_03/3540/334-G.pdf
I think the idea was to give access to the control system for lubrication.

Thanks guys.
The model in the above photo actually has a removable lid, extends from the canopy rear to the back of the cowling.
I thought about a lid, even a small one but that would require more work than I'm up for.
Fredvon4,
I took a look at the sliding canopy article, Part 2. I felt like I was disarming a bomb. ???
Thanks for the replies.

I know I am going to regret this, but yes, this has been done. Either a removable canopy, or a canopy that opens and closes with a slide like a real thing has been done. For the latter you sure need to have two to start with, cut the first one along the split lines, and then make the sliding portion out of the remainder. I mocked it up using a very similar arrangement to Bart Klapinski's Tempest but I didn't actually put it on the airplane because I ran out of time, and I didn't quite work out how to maintain the rigidity with the canopy cut out of it.

I think Windy did this with one of his last stunters. The plane was a take apart plane, the cockpit came out through the bottom of the of the canopy area and then the canopy was a bolt on item from the bottom as well. It pretty complex, but then it was Windy's thing.

Let's backtrack a bit.
Am I being overly concerned or is canopy replacement not a bad idea?
Thanks,
Charles

lots of airplane models out there with thousands of flights and no need to replace the canopy. I am totaly not sure why you feel this is needed.
but hey, you have your own agenda so do what you want,,
Me, I am more concerned about building a solid control system and a straight light airframe
I only had one airplane where I needed to get inside the canopy and that was because the pilots head fell off,,

Hi Charles. I only ever needed one canopy removed and that was because of an unplanned inverted maneuver! I would think that barring that, if the canopy becomes scuffed, etc., one could simply sand it in place and refinish. Besides....your ships are too pretty to land badly! %^@ H^^

To land, one first has to take off.

Brett,
I totally understand that comment.
Yes, one by one each and every model I have will be flown.
Absolutely!
Thanks for the reply

You should consider molding your own bubble canopy with a flange that fits the fuselage contour. Perhaps add some extra thickness to the flange areas with more PET (I think that's the kind of sheet plastic used), glued on with CA. That would allow you to bolt it on with about three dozen 00-90 flat head machine screws. Would look awesome, and you'd get hundreds, if not thousands of screaming fans on Stunt Hangar. S?P Steve

Take advantage of modern technology- eight small super magnets mounted in pairs at each corner of the base would do it. Leave a small crack to slip and exacto knife in and pop the magnets apart. Some of the local RC guys use that system to hold the battery in place.

Gentlemen,
Thank you for the suggestions and replies.
Here's a shot of the canopy area. The ink line is where I have the canopy trimmed. I left room in case I decided to use small machine screws.
I was thinking along the same lines as Steve, however, I would like a liminated amount of fasteners.
