I've got four flights on my new Redwing model. But the canopy installation is a pain in the , since the canopy has to be removed for charging the batteries.
So, an alternative mounting was devised. The attached JPG shows how it was done. I happen to have a lathe for making the fuselage fittings, but this could be done with a drill press and a bit of work. The system consists of removing the two blind nuts that were on the canopy "Pegs" and drilling out the holes for clearance of a piece of 3/16 outside diameter aluminum tubing. The aluminum tubing was epoxied into the two canopy pegs.
Then a trip to the local hardware store for a piece of 1/8 inch diameter brass rod. One end of the brass rod was threaded with 6-32 threads, the other end was fitted with a little aluminum button for manually screwing the assembly in place. First used was a piece of 6-32 threaded rod, but it made a LOT of grinding noise while the the threaded rod was pushed down the inside of the aluminum tube.
Several club members indicated this would not work for a gasser model, since the brass rod could vibrate out during flight. So, one club member modified the design for his gasser with a very small hole in place of the threaded end. Next, a very small spring clip was used to secure it in place.
Now, just unscrew the single piece of brass rod, takes a few seconds and the canopy is free. And re-installing the canopy is just as fast, with the aluminum tube guiding the way.
Might replace the brass rod with a piece of 1/8 inch diameter aluminum rod from a local metal supply house some time.
Take a look a the attached photos to see how it worked out.
Retired and the days are just too short, busier than ever!
I have to say that magnets and similar aree often a dead loss on many of my models ... and I resort to blind nuts / hold down bolts ... pins and latches.
Adding a block to carry a blind nut or latch is my usual modification.
Neat Denny ...
I've got a Hanger 9 Kantana model that uses magnets. How this works is the canopy is slid forward, so two "Hooks or Catches" can engage the fuselage. Than the canopy is slid backwards against the magnets. No way this can come loose, it's worked very well.
To bad the Kantana is no longer available, it is a very good midsized model.
I pretty much always just put a single rubber band around the nose of my mini ultra stick, just incase the.battery comes loose or the hatch fails.
no modification necessary :p.
If you pass 2 BBQ skewers all way through fuselage, just below rim of hatchway .. harden area with epoxy, small plastic plates on inside or similar so they don't pull through ...cut of ends suitable to put a couple of office style rubber bands to ... easier than all way round nose band ...
I actually use 2 bands ... sometimes 3 ...
