In need of guidance for wireless servo control with analog joystick

Projects General Guidance

Hi there,

I'm fairly new to all things arduino so my apologies ahead of time for improper terminology or a slight bit of confusion. I've been able to achieve wired control of a servo with an analog joystick, but there seems to be a bit of a disconnect when it comes to wireless control.

The end goal here is to create a handheld, long range remote that will be able to control a continuous rotation servo motor attached to a UAV. This servo will raise and lower a vessel to take water samples out of a lake.

Equipment being used:

FrSKY DJT Transmitter Module DJT - FrSky - Lets you set the limits

FrSKY Receiver https://hobbyking.com/en_us/frsky-d4r-ii-4ch-2-4ghz-accst-receiver-w-telemetry.html

Arduino Uno

Feetech FS90R continuous rotation servo (plugged into receiver) Pololu - FEETECH FS90R Micro Continuous Rotation Servo

Analog Joystick https://www.lelong.com.my/arduino-3-axis-xyz-ps2-ps3-analog-joystick-controller-module-5-pin-robotedu-198727407-2019-11-Sale-P.htm

Here is a short YouTube video that is somehwat similar to what I'm trying to achieve: Arduino nano + RF transmitters FrSky DJT 2,4 - YouTube

Any input or guidance on how to generate a signal through the arduino for the transmitter to send to the receiver and ultimately control the servo would be greatly appreciated.

-Regards

If you look for iforce2d cheapass transmitter on youtube, he has a series where he builds an arduino rc system.
Think you will find the range may be limited but this would of course be governed by the transceiver modules you use as opposed to that which he uses.

Is this remote-control intended to be separate from the system that controls the UAV in flight?

How long is "long range" in yards or metres?

If this is intended to be a separate remote control then I reckon it would be easier to implement with a pair of nRF24L01+ transceivers - using a high-power version (with external antenna) for the hand-held unit. I can get over 100m range with a pair of low-power versions when there is clear line of sight.

That's what is used in the link.
