Returning to flying

       Remove this ad - become a site supporter!
I have decided to come out of retirement from flying, now I see the new 2.4 transmitters. I have the older Optic 6 on 72MHz. I can buy a transmitter but do I need to replace all my receivers or are they cross compatible?

Re: Returning to flying

Welcome back to is not absolutely nescessary that you swithch to 2.4 if your 72mhz is still in fine working order. But if you want to, you will need to change all your RXs to the brand of the TX you choose...the 72mhx RXs are not compatible with 2.4ghz.

I have two Hitec Optic 6 txs...I just bought the 2.4 TX module and it came with two RXs for 2.4. I did not want to change my TXs because the Optics are very easy to program and have been a solid transmitter for me. So I have one TX switched over to 2.4 with 8 planes and I have the other still on 72mhz with 8 planes.

You can fly Hitec or use the other "low tech" stuff!!

Re: Returning to flying

Sorry, but you need 2.4gigahertz receivers as well..... just the same as when 72 megahertz came out and everyone was running 27 mhz...

if your 72mhz equipment is still working, run it into the ground.

Re: Returning to flying

As long as they are in good shape, you can still use your old 72mhz.
You can also get module upgrades, i.e. or other than hitec and just switch modules to run 2.4ghz with the optic 6.

Just remember any module you buy requires a corresponding reciever from the same manufacturer. So, be sure to check reciever prices before purchasing any transmitter module.

Re: Returning to flying

Welcome back. There aren't many flying with 72 at the pgam field in Prince George . Just one person out of five had 72mhz. We are flying most days when the weather is good. Hopefully will see you out there. You can pm me if you want and I will let you know when the regulars are going to be out there. Phil

Re: Returning to flying

I only use 72 MHz, no issues at all (aside from my thumbs). The less people using it the better - don't have to worry about two people on the same channel. So long as you can still get the parts I won't change.

Re: Returning to flying

Sorry. You will need new receivers as well. It's like when you changed from 27 MHz to 72MHz or From AM to FM or PCM.
Lead, follow or get out of the way!
