The Super Cub was my first plane nearly 3 years ago. I think I’m on my 8th plane now. :-)

Thanks for the qucik reply! I’m acutally working on mounting them on the wings – i’ll verify that I have ~3/4″ down and up. You upgraded to a new plane or tested it’s impact force?

I don’t have the plane anymore but I think the travel from neutral to full down deflection was about 3/4″. That means about 1.5″ total travel from full up to full down. You definitely want an equal amount of down vs up travel.

What is the overall travel of your ailerons? from neutral to full up what is the distance covered at the trailing edge? (more importantly) what is the distance travelled in the down position? I’ve got a nice 45 where they butt up to the back of the wing, but am curious if photo 7 (showing how long they run over the wing) is the aileron in the extreme down position, and if so what is the distance between the trailing edge of the wing and the aileron?

Thanks =-)

Happy flying.

I took my stock Super Cub and removed the wing struts, and installed reinforced packing tape on the bottom of the wing. I now use a 3 cell Li-Po battery. I also removed the stock elevator, and installed a Trojan T-28 elevator. I can now hold a hover for 6 or more seconds, inverted flight is now possible, I can also fly very slow with ease. I have toyed with the idea of making the wing flatter and less of a V shape. I am hoping this will aid in a more stable inverted flight.

I’m am contemplating doing this to my Supercub as it’s either mod or but a different 4 channel plane.

Question is, how did you make your cuts so neat? Did you just use a very sharp craft knife ot did you use something like a dremmel cutting disc? Also how did you dig out the recess for the servos to get the bottom surface flat?

Excellent instructions btw!

Yes I know, I sell helicopters!!
But I do like flying my HobbyZone Super Cub as well. Which brings me to my point in time, I will be modifying my cub very shortly, with a BL-480 Brushless motor, 4 x Hitec HS-55 servos, and doing the aileron modification you just completed (quite well I might add):) Via a DX7 2.4Ghz Spectrum transmitter/receiver system, and 3 cell LiPoly battery source.
I will be using your photo instructional document in order to complete my task for the aileron modification (you did a marvellous job).

When completed, I will be happy for any interested parties to view my flying exploits on YouTube.
Thank you for the opportunity to add to your blog.
Cheers: Gary:)

If it was using only rudder before, you’re in for a treat. I know all about the aerodynamics involved, and not only is using rudder only a sloppy way to turn, it is a fairly unstable way. Hope your new mods work out!

Steve, what you don’t realize is that I did the same thing later, to the same wingtip. It’s been double-epoxied back together. Soon my whole wing is just going to be one flying mass of hardened epoxy.

I’m heading over to Some Dude’s today to pick up push rods, EZ connectors and servo extension wire.

Dave, that looks really nice! My favorite picture is number 7, a close up of the wing tip I tore off in that spectacular cartwheel landing. Gymnasts practice for years to get that kind of form.
