This one isn't "just like his" but it's still a boxy trainer. This one is the Hangar 9 Alpha trainer RTF for $289.99 from Horizonhobby.com.

Or the Tower Trainer, which is almost dead on the Super Star with small differences. Comes with the same radio as the Super Star just relabeled with the Tower name.

There is no issue with the Evolution engines that I have experienced. Start easily, needle settings are preset from the factory to give the newcomer to glow a quicker learning curve. You can only adjust the needles so much until you hit the needle stops, which in turn helps prevent an over lean condition(too much air and not enough fuel) or too rich(too much fuel and not enough air). Great idea in my opinion.

Hope this helps out some.
