Ritewing Mini Drak TBS Unify Pro HV/RMRC 1.3ghz VTX Hatch & Duct by zanthor

UPDATED!
There was a design flaw with the original version of this... the leading edge caught the wind, and it worked it's way free... I ended up EJECTING my VTX/Antenna doing 85MPH... 285ft above the ground in a dive... needless to say I'm building a new drak.
This new revision is designed to be printed with a TPU hinge that is glued to the airframe and a rigid filament hatch that does the job of keeping things in place. With the leading edge glued in place there should be no problems with this design, I'll be testing it soon and will keep a close eye on it for wear and tear. (In my prototype I'll also be tethering the VTX to the airframe so if it comes loose it won't be an epic failure.)

I stuffed my TBS Unify Pro HV into one of the hatches on my Mini Drak and it was fine when it was 50F out... but at 75F I had it overheat and nearly lost my plane because of it. So I fixed the issue.
The hatch is printed out of a solid filament, and then once installed you heat the front end with a heat gun to allow the duct cover to form to the planes contours. Once it sets, use a hot wire to melt out the appropriate amount of foam to allow the duct to work.
Open to the top with a duct to run air under, this should solve the overheating issues. I ran this static on the bench at 200mw without overheating for 10 minutes...
Edit: Added a hatch without a VTX mount but still the front tongue for a naca duct intake with rear exits. This was simply because I wanted symmetry on my plane hatches!
Edit: Added a hatch for the RMRC 1.3ghz vtx uncased with a 20x20 heatsync attached!
