"I have upgraded my 9X and I'm very happy with it! Sorry if my opinion upset you but thats why it's MY opinion. "

"I would highly recommend also getting the FrSky module/receiver, smartieparts.com board and change the firmware to er9x. The FrSky make setting up a fail safe easy and the er9x makes setting up the radio for the APM a whole lot easier. "

"The APM does not have a receiver but the 9X comes with one."

"No you can not with a stock 9x but if you get a FrSky module and receiver that do CPPM you can do it."

"No problem glad to help."

"Zachary, I just wanted to say thanks for all your help! I have installed the smartieparts board, flashed er9x and have everything working in CPPM finally. "

"We will see, I have sent three emails since last Wednesday without a response. I don't work in there business but if the company I work for handled customer service like that we would be out of business."

"I always have had great service with 3DRobotics, especially when I have to return a hardware for them to look. My primary contact was thru email and while it took them awhile to respond (I have to send a couple more emails), usually within that…"

"I' happy to say I really like my 3dr radios and they seem to be working great! Unfortunately 3DRs customer service is still sucking big time. Tomorrow it will be a week since I started emailing them and I am yet to get an email with a RMA!"

"I tried all of them last week and the only thing that worked was doing it the same as the APM1. Also if your using a FrSky receiver make sure you bind it before you install the jumper on it."

"Truthfully I don't remember but I will gladly look when I get home today. "

"The 9x is not new RC user friendly, I've changed mine over to a FrSky module and receiver so that I have a fail safe (be aware you don't have any fail saf with a stock 9x). Even with that change the stock programing is a royal pain so now…"

"I'm no where close to an expert at this but I had to plug channel 6 out of my receiver into channel 5 on my APM 2 to get it to work. I know someone here told me why but I don't remember. "

"Are you using the receiver that comes with the 9x? "

"If you don't want to wait you can get a 9X here. http://parkeflyer.com/transmitters/fs-th9x.html"
