RE: tower hobbies glow engines
Endemic with most of the cut rate and rebranded engines has always been a lack of consistancy. Thats just another way of saying poor quality control. Some will be fine and many more will not. Reducing quality control standards is simply an easy way to reduce costs. So you pay your money and take your chances.
Since the poster seems to be a relitively new flyer the OS engine makes a lot of sense, these are the people who will benefit most from very consistant and just about the best user friendlyness out there and in particular the AX series.
I could care less about absolute max power and to brhinaz The 65AX will indeed make your sixty sized trainer set up and sing. And you will experiance outstanding reliability.
