Yeah if you have JR, you can use SmartPro and make a cable yourself. 2 MONO jacks..I guess
There's a link to smartpro on FMS's site..you'll see it on main page.
2 wires for mono jacks...me thinks
There's a diagram and software for different TX...select the one you want ..I guess.

Just makesure the TX is set PPM

If you're brave, you can pop the return off of the throttle stick of a gamepad.
Just dial out the gain in window's gamepad menu.

But just to learn oriantations..FMS is fine.

CRRCsim is also a free ware.

RC Plane Master has a FREE demo..it just stops after every 5 mins.lol
But you just push fly again.lmao

You can also download Preflight DEMO for FREE...no time limit.
but only 2 channels
mmm...yeah i use to just turn controller upside down.

Just to get familar with oriantations. Out of zip file version is fine.lol

I'm posistive there's links to photoistic sceneries up the wazoo for FMS.
Some of them look just like Reflex and Aerofly.lol
I'm also positive there's links to a skybox converter pastes all over FMS's site.lol
