How to convert a micro Servo in a mini ESC for a brushed DC motor: for FlySky FS-i6 with FS-iA6

ELECTRONICS:
- FlySky FS-i6 transmitter.
- Receiver FS-iA6.
- Micro servo (in this case, a TowerPro SG92R of 9 grams).
- DC motor (in this case, an 8520 motor that runs between 3 and 5 volts).
- Battery 1S of 3.7 volts running at full capacity (4.2 volts) or a 2S of 7.5 volts that runs at half voltage (less than 6 volts). The receiver accepts a voltage between 4 and 6 volts. Otherwise, it produces an alarm sound due to inadequate voltage.
- Two resistors of 2.200 Ω.
CONFIGURATION OF THE FLYSKY TRANSMITTER:
I have the transmitter in mode 2, that is, with the throttle in channel 3.
So, for channel 3, you should:
- Reverse the direction in the Reverse menu (if needed).
- Trim the neutral point in the Subtrim menu.
In addition, you have to adjust the throttle curve in the Throttle Curve menu. The curve must be adjusted by setting the value 50% at point L; 50% at point 1; 50% at point 2; about 60% at point 3 and 100% at point H.

I think there will be another problem when you customize the TX without "perfect ESC-ready" of the board for micro quadcopter. I'd prefer desolder the mosfet and modified it to be a DIY Brushed ESC. I use n-mosfet IRL520N + in5819 + Resistor 100 Ohm + Resistor 10K Ohm to build micro brushed ESC. (cheaper than ever and stable)

muito bom

Nos compartes el diagrama?

[@davidlombardi7295]

How did you figure out what resistors to use?

[@FisicayQuimicaCanal]

hi, i didnt really make any test to find the resistors; anyway, follow this steps: STEP 4

Funciona???

[@FisicayQuimicaCanal]

funciona pero muy mal, es mejor comprar un ESC

[@rastapezl]

Hello friend. 1S or 2S lipo on reciver???

[@FisicayQuimicaCanal]

los receptores funcionan entre 4 y 6 voltios, necesitas una pila 2s minimo, lo suyo es k uses un regulador de voltaje para alimentar el receptor

[@rastapezl]

@@FisicayQuimicaCanal probaste meterle 1s? Es que tengo un microproyecto

[@rastapezl]

@@FisicayQuimicaCanal en el video parece una lipo de 1s pero tu lo sabes mejor.
Meterle un 7806 para ese consumo serviria? Bueno igualmente lo voy a probar en 1s gracias y quiza te pregunte mas jejejeje

[@FisicayQuimicaCanal]

@@rastapezl las 1s sirven porque cuando estan totalmente cargadas, tienen un voltaje de 4.2 voltios, que entra dentro del rango admitido; pero no puedes usar una 1s por mucho tiempo pork en cuanto el voltaje baje de 4.0, el receptor no funcionara adecuadamente

@@FisicayQuimicaCanal el mio que es uno normal esta funcionando hasta 3,4 que ya se pone a temblar el servo y no se centra. Lo voy a poder usar finalmente a 1s
