I actually have the REFLEX sim. It is a GREAT sim. Looks great and isvery realistic. Has alot of great options as well...Only down side isthere is no support for it. No updates no new planes/helis...but thatsfine for me. I bought this a few years ago, It was expensive then...not sure how much now.
I have my own buddy system too. I have the cord and the extra tx....both are futaba plugs...But for some reason they lose connection at times...I think they pull out just enough...It makes it really interesting when Im really low and I realize I dont have it...Luckly the instructor always acts as he is flying too
