This article is the continuation of Part 1<\/a> of the Super Cub aileron upgrade tutorial.<\/p>\n

I finished installing the servos for my aileron upgrade today. Here’s what they look like in action:<\/p>\n

<\/p>\n

Thanks to the Spektrum DX6 radio, I can flip the “flaps” switch, and both ailerons go down (called flaperons). This supposedly will give more lift during take-off and landing, so I can keep my speed down without losing lift. To get the flaps to work, I had to set the travel adjustment on my radio to positive 0% and negative 100%. This wasn’t readily obvious to me at first, and it took some tinkering to figure it out. Otherwise, the ailerons would swing upward in non-flaps mode, and downward in flaps mode. That would not be desirable, though I’m curious to know how the plane would fly like this.<\/p>\n

Here’s what the servo and push rod look like installed:<\/p>\n

<\/a><\/p>\n

You can also see 5 of the 6 channels plugged into the receiver. This is because each servo needs its own channel to operate in flaperon mode. If I just used a Y-harness instead, then I could have saved a channel, but I wouldn’t get flaps, and we simply can’t live without flaps, can we?<\/p>\n

Here’s another close-up of the servo mount from the bottom of the wing:<\/p>\n

<\/a><\/p>\n

I connected the push rod to the servo control horn with DU-BRO EZ connectors. They make it so you can adjust the length of the push rod more easily by tightening and loosening a screw. The other end of the push rod attaches to the control horn on the aileron, with a simple dog-leg bend (two 90 degree bends, actually). I used two needle-nosed pliers to put the bend in the rod. This should<\/b> prevent the rod from coming out of the control horn during flight (yikes).<\/p>\n

I haven’t inserted the wires into the wing yet. I plan to cut a very thin slice along the bottom of the wing, and shove the wire in it without having to tape it shut. We’ll see if that works.<\/p>\n
