Hello after 30 year break I'm getting back into flying R/C planes. So much has changed. I've managed to wrap my head around the new 2.4 radios, Foam planes, and even electric motors. I really like the flight test planes and will be mostly flying those for the near future so most of my batteries will be 3s. I am one of those "buy it once not twice" guys , so I would like o get a battery charger that won't limit me. I have looked at a bunch of them Imax B6, Turnigy Reaktor 250 w/Reaktor 240PS, and bangood has the ISDQT Q6 pro w/300w PS. I am pretty confused by all these chargers, and a bit hesitant, as I don't want to burn my house down. Ideally I would like a good charger that I can charge 3-4 batteries , will not require electrical engineering to assemble, and costs between $30-$75. I'd appreciate any help and explanations.
