I use this charger for gymnastics of tail blades MS Composit of 107 mm and blades of basic rotor MS Composit of 680 mm. It would be desirable to note that for tail blades it too powerful 30mAh is too big current for the small accumulator better to load this charger with resistance 220 Ohm. We close resistance 220 Ohm on and - the plug soldered from old broken servo to wires which are connected to the blade accumulator (for gymnastics). And as there it is possible to put a light-emitting diode a current consuming at 4.2 volt approximately 5mAh. If so to load this charger that it gives out a charge current approximately 1.5mAh. It will prolong service life of these accumulators. And the gymnastics instead of 10 minutes (too small time of a charge too big current) proceed about an hour. But for the big blades the current 30mAh is too small. I have connected two blades MS Composit 680mm to this charger (having disconnected loading resistance and a light-emitting diode) and in 3 hours pressure on accumulators of these blades has risen all on 0.08 volts such current (30 mAh) them it is possible to charge the whole eternity. To a socket from servo which I have soldered to wires which connect to blades, (resistance 220 Ohm and a light-emitting diode we disconnect at gymnastics of the big blades) I connect charger TURNIGY MAX200W and I put a charge current 200mAh, (choose point gymnas
