Default H9 Cub differential ailes

Hi all;
Any experience with this airplane that'll tell me if I'm going to run into trouble if I don't use differential ailerons? I have a Futaba 7C, so I guess I can set it up, but at first glance it looks like a pain.

There's never been a Cub model flown that doesn't exhibit adverse yaw when using only ailerons. No problem if you kick in a tad of rudder.
No problem either to program in differential throw with the 7C, takes about 10 minutes. On Channel one, (aileron) adjust your end point so that you have more up throw than down throw, on Channel 6 (AUX) just do the same thing, plug the other aileron to that channel. Give about twice the throw up as you have down.

G'day Mate,
You could use differential ailerons, just program in some differential, in the TX, easy.
And/or you could program an amount of rudder/aileron mix, I'm sure the TX would allow that.
Be aware the plane will still fly, without any differential or Aileron/ rudder mix.
It just flys better, with them, all you may need to do, is use some rudder, in the same direction as the turn, ie, left turn, left aileron & some left rudder, & so on.
It's not such a big deal, so don't panic, it'll be fine.

You can also very easily add some differential by simply repositioning the servo arms. It's dead simple to do if you understand the principles. You are stuck with that solution when you've only got one aileron servo anyway. But it works just as well when you've got a two servo setup.

Learning to coordinate the rudder with the ailerons on a Cub is one of life's challenges.
It makes you a better flier.
