0 Graupner FLY-PROFI esc

For my HEIM EP Helicopter i bought this vintage brushed ESC called FLY-PROFI 50 sold by Graupner and released by Japanease propo.

It can be used up to 24volts. I will use it with original brushed vintage motor fitted in the original EP HEIM UNI- MECHANIC 40 Elektro

I will use 2x 3S li-po packs linked in serial for a final voltage of 22.2. I own also a NIB Graupner Lockheed 286 body and i'd want to use it in this project.
