So recommendations for a first engine that will be a good second/third as well:
Magnum .46
Super Tigre .45
Super Tigre .51
OS .46LA (what I got by accident)
Those are four of the best values in sport engines on the market today, jerzdvt. You will be happy to fly any of them. Power for the dollar, I like the Magnum XLS .46A or the Super Tigre .45 ABC. With the O.S. .46 LA you'll be sacrificing a little bit of power for super easy tuning and dead solid reliability. The Super Tigre .51 is a little more expensive but can turn larger props well.
I'd be happy to own any of the four.
