Would sitting the sevo upright in the wing work also?

To upgrade to the Super Cub to use the Spektrum DX6 (or DX7), see my write-up here:

What all will I have to do to use a spectrum dx6 with my supercub? Thanks

I used the 4 servos that came with my Spektrum DX6 radio. I believe their model number is S75. Along with the AR6000 receiver, they too were included in the price of the radio ($199 retail).

What servos did you use? How much did they cost?

It plugs into the Aux channel, and you have to set the wing type to “flaperon” in the radio (I think it’s “FPN”). Search through the user’s manual for “flaperon”, and it will guide you through the steps. I am not terribly impressed with the DX6 user interface, but am unwilling to shell out the extra $150 for the improved DX7 interface. Good luck!

Dave,

I am in the middle of my aileron mod. I am also using 2 servos with the DX6. If you are not using a Y connection for the aileron servos, where does the second servo plug into the AR6000 RX?

Thanks,

Stan,

To insert the servos, I traced their outline with a pencil, then I dug out a hole with my exacto knife. I wrapped the servo in double-sided tape, and then covered it with clear packing tape (wish I had white tape).

You’ll notice that they aren’t exactly a mirror image of each other. The wire comes out of the trailing edge on one, and the leading edge on the other. If I could do it again, I would unscrew the servo arm, and reverse one of the servos. That way they would be symmetrical, but I think this is purely cosmetic.

I can’t tell any difference at all regarding center of gravity. I’m pretty sure the plane is a few ounces lighter, but I haven’t weighed it. There certainly is more room in the compartment now.

About 2.4GHz: Even if there are other devices transmitting on the same frequency, it doesn’t matter because the Rx is smart enough to ignore all data that is not prefixed with the unique number that’s hard wired in the transmitter. It’d just have to work harder to “drop” data coming from web cams, wireless access points, etc. Also note that the Tx and Rx work on 2 different channels, just to be safe.

Dave…
We’ll have to call it the “Super-Super Cub” now..!! Really great job on showing the “how-to” of it. Just not sure how you mounted the servo IN the wing. Is that tape in the servo pic or what..?? While doing this same upgrade “in my mind” this last few weeks… I really thought the dihedral in the SC wing would counter-act, or at least, fight the aileron action. You just proved me very wrong. So much for my “mind” engineering.
Really like that radio system as well. Will be doing some research on that baby. Been looking over the 2.4 Gig stuff… but I figured it would be getting “hit” by every home security cam and wireless phone in any given neighborhood. But reading the AdBlurbs on the system… it seems to search out the “free” 2.4 G channels at any given location. Still seems like you would eventually run into a “saturated” area sometime..??
Also… with that big black box out of the cockpit… what happened with the overall CG of the bird..? Have to add or move any weight around..?
Great job..!!! Thanks for the flight video as well.

Try using some strapping tape or 3M extreme tape on the underside of the wing. With this done you can run with the stock wing struts and have no issues with flexing the wing coming out of dives….just a thought.
