2 channel radio control
 
Hello. I'm trying to resurrect an old "Gentle Lady" sailplane, including updating it to an electric motor. I'm having trouble finding a simple 2-channel transmitter/receiver/servo system. Any suggestions? Thank you.

Most brands have stopped selling the 2 .. 3 .. 4ch sets now ... basically the price of producing a 2ch set is not so much less than producing a 6 or higher. Most people are looking for a 6ch or more nowadays anyway - with the idea to get as many ch's at start - so when time to move up the models - radio is there already.

Its also rare to see a box set now as well ... unlike before - very few Tx's are sold with Rx's and servos. Today - there are so many servos out there and Rx's are in various sizes to suit what model you are kitting out.

I would suggest getting a current radio with as many ch's ... radios really are not that expensive anymore ... you can get multi-protocol radios with 16chs now for budget price - less than you would have paid for a 4ch a few years ago. That multi-protocol then allows you to save money by buying Rx's that are not 'tied' to one brand.

That's what I needed to hear, especially since I haven't been able to find any low channel option. And multi-protocol sounds like a good idea for flexibility. I will look in that direction. Thank you.

You may need 3 channels: rudder, elevator, motor. Most stand-alone radio systems have at least 4-6 control channels, and will be easier to find.

He's right actually .. if you are adding e-motor to the GL - you will need a minimum of 3 ch's ...

Throttle
Rudder
Elevator.

Keep us updated - very interested to see results.

Note that there are lightweight receivers like this. Likely 6 channel but they are very small, only weigh a few gms and you don't have to use all the channels.

As Q shows ... there are some incredibly small light Rx's now ...

I am using the 4ch FrySky compatible ones .. so small and light ...
