Question
Converting a Futaba 7C from FM to 2.4ghz

Long story short, a couple years ago I wanted to get into helis, found a crazy deal on a brand new Futaba 7CHP, but never bought a heli so it collected dust. Unfortunately, this is not the 7UHP, so it doesn't have a module. I'm now picking up a heli so the radio will hopefully see some use.

Since then people have found a way to take the Spektrum DM8 transmitter module and solder it into the transmitter directly in place of the FM transmitter board. As my luck would have it I can not find the DM8 module for sale anywhere, it's not listed on Spektrum's site unless you search for it on Google, and it's not in stock anywhere.

Then I found the FrSky DIY 2.4 module. I hadn't heard of them until I started researching the conversion of a Futaba 7C to 2.4ghz. From what I've read is people have no problem with these modules as long as you avoid connecting it through the trainer port, which I wouldn't be doing.

Ideally I'd like to find a Spektrum DM8, but worst case is I'd try out the FrSky module. Thoughts, opinions?

I've converted my 7C to FrSky and it works perfectly. All my planes are now on FrSky. It's worth putting the switch and light on the front so you can see the light.

You know the 7chp is not just a heli radio... In any case I converted my 7CHP to Frsky. I left the 72mhz board in and put it on a switch, now I can switch back and forth.

That's what I was hoping to hear, thanks guys! Yep, I know it can do airplanes and helis, I like the throttle that doesn't have the notches in the movement.

I'd like to convert/upgrade my futaba 7c 72mhz to 2.4ghz...

Is it easy to do? just follow the instructions?

I'd like to have a switch where in I can switch to 72mhz or 2.4ghz. I have lots of 72mhz receivers and I dont want to replace them.
