Thank you. I'll give a look at my charger on my next flight and will try carlrich second option. My charger has a display an it effectively shows how many mah's are beeing delivered. Unfortunately I have to wait two more weeks to give it a try because I'm going oyt on a trip and can't take the magister with me, but I'll let you know my results ASAP.

Carl, you should really try brushless on it, or if you want to feel something closer to how it performs (just on the climbing rate) then install an APC 12x6 SF. It really pulls!, we tried it and now my other friends have ordered them! (We fly at 4900 ft above sea level. I don't know how well they'll perform at lower heights)
