Hello all from Ontario Canada: I am wondering if anyone has installed vortex generators on their X Air Hanuman/Hawk? I can install them myself, 10% of the length from the leading edge, (4 inches apart from one another) all across the top of the main wings and all underneath the horizontal stabilizer for about 240$ CDN.
The vortex generators are about 1 inch long and about 5/8 inches high and about 3/8 inches wide, made out of clear plastic.
All instructions are provided except what adhesive to use - any suggestions??
Some people inquire as to why an owner would install vortex generators on an aircraft that already has a low stall speed, but I guess my response would be making an effort to reduce stall even lower but more importantly to reduce total take off distance; even if it helps a mere 30 to 40 feet.?
I'm not 100% going ahead with this project but I am quite confident I will notice a difference if I do.
Any advice or suggestions is greatly appreciated.
Thanks,
Justin

That interesting. I wonder how they would stick to the fabric of an X-air, and if there would be any negative effect at higher speeds.

A few have tried with ZERO results....??? They dont stick and there
is too much movement in the fabric

That was my gut feeling on it as well. On an aluminum or traditional dope and paint I could see it working, but the mylar/dacron has too much flutter and flexibility. I guess if someone was willing to risk damaging things by using two part epoxy or a mechanical fastener, maybe? Doesn't seem worth the risk in an attempt to reduce the stall speed of an already very low stalling aircraft though.

Thanks for the prompt replies!
I decided I am going ahead with it.
I spoke to 4 others with these VGs on various fabric planes and they all wished they would have installed them years ago.
If they don't work worst case, I'll take them off and return the product, but I don't see why they wouldn't work, especially underneath the horizontal stabilizer.

Quite a lot of effort in my view - not to mention a thumb suck as where best and how far apart to place them given the marginal improvement on an already slow fabric covered aircraft. Of course those that have them swear by the STOL performance gain, which is human nature after all once you’ve paid your monies and spent the time – not so! ?? ?

Hi Bill,
I have tried multiple times myself to contact them as well.
I feel like 'we' (this x air community) are on our own with the X-Air. We help out each other when we can.
Sorry about your deposit.
Good news is - a Canadian company in Quebec makes X Air coverings:
.com?
Gary is the owner. He is A-1 with customer service.?
Hope that helps,
Justin

There was a company on the Isle of White U.K. made replacement fuselage covers that worked out lighter than the original and were more mould resistant.
