Hi Guy's i'm looking for some help on how to make the canopy open and close on my BVM F-100 any pictures of others would be great. Also locking mechanisms would be helpful.

Hey Greg
I have built three of them but they were all movable by hand not servo or air. Joe Grice has done this!! you could contact him

Here's a video of how I did it on a BVM F-100F model...

If you look at the aft hinge plate, you can just see the plywood horn that I added to it to lift and lower the canopy. The lower attach point of the lift cylinder is attached to a standoff on the fixed portion of the hinge plate. That way, when you unscrew the hinge plate, the entire canopy comes off as a unit, canopy, hinge and lift cylinder. You can see the Robart "quick disconnects" I put in the lift cylinder air lines so I can completely remove it.

There are hooks under the canopy rails that go into slots in the canopy "sill" on the fuselage. Just forward of the front canopy hoop inside the fuselage you can see the locking cylinders. These are operated with the lift cylinder with a sequencer.

More details are in this thread:

BTW, you can see that the hooks on the canopy face forward, which is scale, but its actually easier to do and lock more securely if you make the hooks face aft. That way, when the locks close, they tend to try and push the canopy forward, up against the forward hoop, instead of pushing it aft, possibly making a gap between the fuselage hoop and the canopy hoop.

Thanks Bob,

This is great info on how to do this, the only question is did you use bv's air cylinders or some other manufaturers cylinders. Also how did you attach the two locking cylinders to the inner brass square tubing.

Its not a BVM but a yellow F16 I did a canopy on. I just used the servo slow function in my radio and 2 servos. One servo to open and close and the other with a hook to latch it. They run off the same channel and was pretty easy to do. I am really glad I spent the extra time on it because it makes the model.

Hello:

I open my F-18 canopy,but I used another system for block, one servo and two links that entry in the windscreen. I put video and photos:

Greg,

Yes, I did use BVM cylinders for the canopy. one inch for the locks and I think it was a 2" for the lift. The ends of the locking cylinders were simply bolted to the square tubing.

Thanks Bob, i placed an order with them earlier and got two 1" cylinders and one 1 5/16'' cylinder so i will have to see if i can make that one work or i might have to order the 2 3/8" cylinder that they have.
