Aren't the 425 and 550 frames supposed to be the same?

I tried to install a genuine Gaui 550 fiberglass canopy on my 425, and it doesn't fit.

If I pop the canopy on to the pins, it doesn't come anywhere near hooking on the bottom.

It looks like the canopy mounting pins should be moved to the rear holes on the frame for the larger 550 canopy. The instructions for both the 425 and 550 are not clear on this.

Okay, so I moved them back. Now the canopy hits the swash plate linkages in front, and still won't quite fit. If I disconnect the linkages, the canopy fits perfect.

Do you have to hog out the canopy with a dremel and sanding drum to get it to fit?

425 and 550 frames are completely diffent. 550 is designed around 2x 3s packs while 425 a 6s pack in the nose.

I'm talking about the current 425 and the current 550. From what I gather there used to be a different version of one of them.

The 425 I have also calls for 2x 3S packs. It's supposed to be upgradeable to a 550 by simply replacing the tail boom, blades, and canopy.

425 can use 550 boom/belt and use longer blade. 550 can use shorter boom/belt to run 425. That does not make the frames interchangeble. These have two different sized frames.

I have a 550 plastic, 550 carbon, 425 carbon frames that I can compare. I also have 550 and 425 canopies to compare if you don't want to take my word for it.

Better yet, you can ask Kyle or Ray up in your neck of the woods.

I did. Ray seems to think it should work, and doesn't know why the canopy won't fit without modification.

The canopy fits perfect with the mounting pins in the rear holes and the swash linkages removed. Like it was made for it.

Screw it. I'm going to pick up some fresh sanding drums for my Dremel on the way home tonight, and MAKE it fit.

If you decide on grinding, you can make any canopy from any manufacturer work (within reason).
My 425 canopy came bare white so I tried the 550 canopy and gave up as it was not a perfect fit.

I have a 550 canopy on my 425. Was a little tight on the bottom so I just had to grind it a little bit. But all the hole line up on mine.

Carpe Diem!!!

The Plastic 425 frames are the same as the 550 Frames.

The Carbon frames are totally different.
