On internet it is very difficult to find how really we can use it..
Every body can buy this ESC ( on EBay for example ) and to be abble to use it we must know theses informations.
The Esc will make a continus beep when you will supply it for the first time.
The Esc module must detect the middle of the servo pulse ( the middle rest position of the throttle stick ) and it needs to use a digital radio control...
This document explains you how to detect the origin of your actual problem.

We can find this FPV 5.8G 10-200mW Adjustable Audio Video Transmitter Module TX-58120.
it is a cheap module .
I found how to connect it on a chineese internet site :
Pins on module TX 58120 5.8G
From left to right :
Pin 1 : 塊 = masse = OV
Pin 2 : 視頻 = video signal

Pin 3 :音頻 = audio signal
Pin 4 : 3,3 to 5 V Li-po supply

This module is interesting because it uses one li-po 1S element , it helps to save weight on flying models.
My application is to use it in kite aerial photography !
If you put a clover leaf antenna, you can reach a comfortable distance of use .
Usually , I remove the antenna collector( to earn weight ) and connect directly the antenna on the printed circuit !

To make the electrical wiring on the module, it is better to use this :

Some Epp kits like Free Air Models kits help us to find and to concretise in a few hours one plane ready to fly for indoor applications !
The Easy model can help us to find a plane with real capacities in indoor flying !
This plane can use a brushed motor called Mig 28 , it can offer from 10 to 60 W and is 46 gr weight !
The flight configuration is programmed for a weight of 230 gr !
Wings and fuselage (41gr+ 36gr = 77 gr )
The best configuration will be done if the wing is sticked directly on the fuselage !
Some brushless engine can be used , this can help us to have a better equilibrium of the plane !
One of them is the EM2020-31 with 2500 kv 11gr and 16,5gr with 2mm connectors !
The power can reach 5O W !
We are going to use the classic motor handle .
