I'm a big fan of the LA .46. I think it is the most user friendly of all the glow engines. Under powered when compared to the AX and old FX OS engines but way easier to operate. Way cheaper too. Engines are one of those choice things and if I was buying a new glow two stroke and thinking in the long term it would be the AX. I'm a 4 stroke guy though and for someone new to them I would go OS. very user friendly. To me a Magnum is just a parts engine. That's just my thinking, I know they have a following but I'm not one of them.
