There, you got my trivia of the day.
Right you are.

VG's


I forgot to post pictures of the VG's on my funcub, so here they are!

All i can say is, besides the metal motor mount upgrade, this is the single best mod iv done to this plane! The effetcs are great!

Please explain in detail what the plane does different? I have seen them on the 3DHS Big Foot and i thought i overherd Joe and Ben saying that it did not help that type of plane much. Would like to know what you found, and how you tested them? Thanks Scott.

did you find that they provided more control at just above stall speed?

The airplane now has a reduced stall speed, and will stall at a higher AOA (angle of attack) and now lacks the crazy wing rock you would normally get at high AOA's with the stock funcub. It takes off shorter with less power now. it takes off just as short at half throttle now with them, as it did at full power without them. I also mainly noticed a high increase in aileron effectiveness. These are the main effects that iv noticed with the VG's. I tested by flying the plane without them and noted the characteristic at stall, slow speed, take-off distcance, etc.. then i immeditately went on installed the VG's, waited for them to dry (that took like 5 minutes) then went and flew again doing the same tests. And then i began noticing the effects.

You just eyeball it. lol. Spacing is not so crucial as much as the angle they are relative to eachother which should be about 45 degrees (roughly).

You row the VG's up at the 1/3 mark between the tallest part of the airfoil and the Leading edge of the wing. That is also crucial.

I have an extra 300 and they tip stall. Have you tried this on a similar airplane? Do you have anything on stall fences as well?

As you speak, I am working on the ultimate Funcub/ Bushcub... stall fences are in the picture... Its gonna have it all.. stay tuned! and VG's work great for aerobatic planes! the get rid of nasty wingrock when harriering.

Would you buy a used airplane from that man?
