I wasn't going to post pics but decided to swallow my pride and do it.
Here is the bottom side. I used a dremel with a cutting disc to cut a channel for the servo wires to the fuselage. I couldn't figure out a good way to cut the holes for the servos so I just cut the outline with the dremel cutting disc, then just kind of dug out the rest with a round cutting tip. I also cut little slots for the servo arms so they could get a little more travel throw in them.
The servos are just cheap Spektrum S75's, but they work great for this application.
I decided to go all the way out to the end of the wing because I wanted as much lift as possible at the tips to make the ailerons more effective. The ailerons are 12" long by 2" wide. I used hinge tape to secure the ailerons to the wing.
This is the top of the wing. I'm still using the white plastic wing braces. Since I made the ailerons so wide I had to move the white plastic piece that holds the struts in a little. Unfortunately The wing was too thick to get it to poke through so I had to dig a little hole to recess it a bit.
You can see the carbon bar I used to remove the dihedral Again I used the cutting disc on my dremel to cut a trench for this. I laid the wing on a table and placed a heavy object on each end to flatten it out. I then used 30 minute epoxy to glue it in place. Once the glue was set I placed a strip of 2" strapping tape over it to make it more secure.
All in all I am very pleased with how well the ailerons work. I learned a little bit about cutting foam too.
Mainly, don't use a box knife to cut it. It pretty much just tears chunks out of it.
And just in case you missed it, here is a video of the ailerons in action.

, but the vid of your cub rolling is by far the best i've seen. Nice job.
Not bad at all. I have seen much worse. Glad you tried it out! Kevin
