Yep, that's very true. I have a Goldberg Tiger 120 and it has flaps (I also have a Goldberg Wild Stick 40 and it too has flaps). Both of them have a Y connector and go into the AUX 1 channel as pointed out by opjose. This works fine. A bit of a pain to properly set up the linkage, but once done, it works fine.

Now with that said, I must add that I just about never use the darned things. With the Wildstick 40, all they do is enable me to do loops in just about the length of the plane.. with the Tiger 120.. well, I don't know what they do because when I use them, it seems that nothing happens. That is one big wing with a lot of wing area. Those small flaps are pretty insignificant.
