[QUOTE=Rfisher30;93408][QUOTE=Rfisher30;93406]Flying in the Houston area is just "hot!" My solution is to replace the little door knob for a 3D printed knob that allows me to crack open the door about 1". Cruising ~100 mph, the doors are rock solid and the cabin is so much cooler.

Lesson learned: If the latch vibrates the knob and the door flies open, there’s a good chance the door will be seriously damaged. A Positive locking mechanism is Required. I removed the *.stl files from Facebook and continue to work the problem.
Built these over the last couple of weekends. It cracks the doors open about 1/2" and positively holds them in place.

What kind of damage was caused? The kitfox videos always show just unlatching the door and letting it go. Just wondering.

Coincidentally, I watched a youtube video from bowenaero.com 'Project Kitfox' today and he addressed this exact issue. He's using a latch that provides 2 positions, fully closed, or door held a 1/2 out open but still latched. I thought this was an elegant solution to this problem.
You can watch the video here; https://youtu.be/MUeRMN9m90Q?t=266. It will start at 4:26 into the video where he starts his discussion of this latch. Might be worth more research.

I love the airflow you get by using this method. One downside. I flew for an hour to San Diego with the door propped open a little. This was the first time I did this and I had about 10" of the door seal come loose from the adhesive that remained on the plexiglass. Now Im researching a different kind of door seal that might have a better adhesive. Sort of the same thing I am doing for the turtle deck foam seal.

I stuck the weather seal to the aircraft side of the gap. With the doors cracked the weather-stripping isn't in the airstream and you don't see the adhesive strip when looking at the door from the outside.
