canopy mounting methods

Yeah,
rattly canopies can be the loudest thing on the plane.

When I did my EMC and Dave Funk built his Hydeaway, we were amazed how much 
stiffer the fuse was if the canopy base was securely tied to the fuse versus 
a pin and a quick release mechanism. On an E powered plane it may not be as 
critical since there is no vibration but on a glow shaker it surely makes a 
difference. I ended up with 3 - 440 aluminum screws and 3 pins. There are 2 
screws on the side of the fuse towards the front of the canopy, one on each 
side, these screws run in the same plane as the wing tube ( side to side ) . 
The 3rd screw is at the rear most top of the canopy and is oriented 
perpendicular to the wing tube ( top to bottom ). The 1st pin is in the 
front center of canopy and the other 2 are between the front and rear 
screws, all 3 pins are oriented perpendicular to the wing tube ( top to 
bottom ). I copied and modified what Dave Lockhart had done on his EMC's but 
used 1 less screw, used aluminum screws and the overall mounting method was 
a bit lighter. My ready to fly EMC canopy as it sits on the plane is 4.6 
ounces with screws and is painted silver w/black fogging and it clear 
coated.
I use a Hanson rotomount in my EMC w/an OS140 RX, I have absolutely no fuse 
side to side wobble with the engine running.

Hi Jay,
The neatest thing I have seen in many moons is what George Asteris does.
It's a quick release, with pins at the front, and a single sliding hatch pin 
at the top of the back.
The sliding hatch pin is made of music wire and brass tube, but attaches to 
a foot-long or so piece
of flexible throttle cable and plastic tube that loops down and forward and 
ends in a pull
tab that is under the wing or on the bottom of the plane. I have no 
pictures, but
you could probably do the same thing with one or two Violett quick-release 
hatch pins,
and kevlar cord running back to a pull tab on the bottom of the tailcone.
That would be E-light!

Hi all,

Before I start my new Impact, I was wondering what kind of canopy mounting
methods were being used out there? Pics are worth a thousand words, if
you've got them, or have a site with them on there.

Mine is a 10/32 nylon screw in the front and a 1/2" carbon pin at the rear.

Thanks,
Jason
