I plan on upgrading the aircraft to use this technique on the prop so that the 3D flight will be more realistic as well. For example, the way the helicopter fly's is by calculating the force on each blade based on the incidence of air hitting the rotating blade (which is angled according to the control positions exactly like the real model). The simulator uses approximations of force on physical surfaces, so in theory it should fly any physical geometry that is fed into it. I am working on an aircraft editor so that people can easily add planes, heli's and quad/tri copters in the future. So far I have 2 gliders and 2 3D aircraft, FT-22, FT-VersaWing, a simple Quadracopter, an EDF Viggen jet, and a TREX-450 Helicopter.
On android devices you use touch controls for left and right sticks. This simulator will work on Windows, Mac, Linux, and Android devices, pretty much anywhere that Chrome and Firefox run. It is a web based RC Flight sim that runs on Chrome or firefox and needs a USB game controller to work (XBOX or Logitech work fine on Windows, on Linux pretty much any controller works). I am making it free to use for everyone, and you can support development of it by clicking a few of the google ads that show up on the bottom of the screen. I wanted to add another free sim to your list, I wrote it and would like people to try it out as I continue to develop it.
