Desi Jugad Brushed ESC from servo motor control circuit is reversible if you keep POT centered.

For this model you can make it unidirectional by replacing the POT with a single qtr watt resister of same value between the two extreme pins and shorting the center pin to one extreme pins.

Nice build superb...... just becareful of auw, motor should not be underpowered....keep checking on weight and reduce as much as possible....wish you  all the best :hatsoff:

Thank you for that!

 :thanks: roman
The estimated auw is 35-40gram with 5" prop. Should give some nice thrust.  ;)

Yes Kiran I am asking about the esc.
The esc is quite simple. The control board from inside the servo motor is taken out with POT. The POT should be centered and it can be used as brushed esc. Only for micro pager motors. If connecting for a larger brushed motor 1 or 2 mosfets can be added. Current amp of this esc is less than 500ma

rcrcnitesh

Thanks bro.
From where did you get the 7mm pager motors?
