That's awesome Max-U52! I'll go check your youtube channel. Again, I didn't know there was a choice of high-low and medium-low gearboxes. I guess that's the reason why the upper hull of my Leo2A6 doesn't fully fit on the left side where the high motor is located. :-/ I just saw it on eBay and asked my friend to order it for me. I'll try to order these motors ASAP. Will get 4 - 2 for the Leo2A6, and another pair for the coming M1A2 which I asked my friend to order for me today (hoping to get it in June or July). BTW, was it just a straight installation, or did you have to solder a resistor or other stuff (whatever that yellow-brown thingy is that I see on the motor)? Also, I just subscribed and I see you have videos on slip ring installation. Will be watching that so I can install the same in mine.
