Indeed, there is some good learning in everyone's posts. Thanks!

Gaz, I am thinking about it for the 1640mm 1/6th scale VQ clipped wing J3 that I will be building soon (as soon as I get the little Cub I killed last year off the repair bench).

It has fairly tiny (even in comparison to my small models) ailerons at the extremities of the wings. The wing structure is as such that flaps simply can't be cut and hinged, it's mostly hollow where they should be and would require more destruction and reconstruction than it would be worth.

As for why? A security blanket until I see how short I can pull it up from drag alone, and now I have a radio with servo speed and stuff, and the never ending desire to mess with stuff Spoilerons would be just a mix, adding flaps probably would result in new wings being ordered I now have my MPX Funcub (in Hobart) with flaps on a DX6i, with no servo speed control, and to be honest, I'm not a fan of of full speed flap deployment, the instant ballooning is more tricky to deal with than just landing a giant docile block of foam.


Oh, another point you raised, Garry, the effect of "crows footing"... I have just seen something like the result of that... Tasmanian Phil's new trick with his MPX Funcub: Slam the flaps down full and basically kill any forward motion, so the plane just hovers stationary and level from the prop thrust alone. That just looks freakish.
