this is what I did.
-I purchased a rocket canopy from Todd.
-Tried to fit the canopy to the RV-4 canopy frame.
-Spent over 2 weeks trying to make it fit. I cut every piece of metal that ran side to side on the frame (I also cut every weld after it was all said and done
-Got the width of the canopy frame to fit the airplane, then tried to make the canopy fit the upper side tubes of the canopy frame.
-Looked at it for about a week and decided to instead of cutting the bottom of the canopy to fit the frame, I would make the frame fit the canopy. I just wanted the best possible visibility out of the back seat for my wife. That is the main reason for the choice.
If you look at the pic below, you will see the canopy frame bulkhead (between the pilot and copilot). If you look at the upper corners, you can see the old location of the side tubes. Those side tubes used to be welded to the bulkhead. The bottom of the canopy is almost 4 inches lower at the lowest location (the rear).
The front section:
If you look at the pics below you can see that I lowered the side tubes considerably in the front as well. The tube that used to hold the front of the canopy was cut and welded to the actual frame. The reason was so I could extend the canopy forward and down. The canopy is approximately 4 inches forward of the original location per plans. I really like the look and think visibility would be a little nicer. But then again the original visibility was not bad. Hope that help, and not confused you more. Send me a PM with you phone number if you want to talk.
The next step is to make the skirts out of glass. That will be a challenge. I have not figured out how to make it flow nicely yet. I need to rivet the fastback prior to the glass work. Still waiting for a bucking partner.
