Looking for F2G Throttle Control

[drigotti]

Hello Experts!
I'm looking to create a single channel proportional TX to control the ESC on an F2G setup. The control would be via a pot with a knob. Range would be minimal as far as R/C aircraft would be concerned. I've looked over the single channel and proportional forums and I can't figure out a clear path to take. Any help in choosing components would be great!
Thanks in advance!

Hi Dave,

Bruno here,

Can you fill me in on F2G? ( I never made it past F2B, OK - participated in some WChs, but still...)
I made a controller unit for my buddy's Basic Carrier Deck twin motor model and it works flawlessly.
Only thing is that the signal goes through the two (insulated) flying lines.

I gave the throttle a strong exponential for better control near idle position.
Later I upgraded this project to a two channel version in order to control the arrester hook release as well with a pico servo.
This version can be connected to a HF TX module (Lemon seems perfect, since you're not in the EU) and any micro receiver would do.
If you're interested, let me know...

You could use a pair of RF-Nanos - one as a transmitter (with the pot), and the other, in the model, as a receiver driving the motor ESC.
The transmitter one would need a small battery to power it, the receiver one would be powered via the motor ESC.

The RF-Nano has a built-in NRF24L01 radio transmitter/receiver, with plenty of range for control line operation. You can get them on AliExpress for less than £3 each. The RF-Nano is about 50mm long, by 18mm wide, and just a few mm thick. Best to wrap them in a bit of heat shrink tubing, or even insulating tape, after making the necessary connections, so that they can't short out against any metal parts. They have a built-in programming port (USB-C on the newer ones, or micro USB on the older type) for programming - something you only need to do once.

If you decide to go this route, let me know, and I'll upload some simple Arduino sketches (programs) for the transmitter and receiver parts. Or you could use PhilG's program that does frequency hopping, full multi-channel control for RC operation - you'd only need to connect up the throttle pot on the transmitter part, and the ESC on the receiver part.

Assuming the power for the model is a battery contained inside the body of the model and the control wires are metallic how about using the two control wires to the F2G model as gnd and pwm from a servo tester operating an ESC in the model?

Martin,
I'm interested. Can you post link(s) to the setups?
TIA
