I put an OS .25 FX on a Global Mini Magic Extra, and it unbelievable. It's really a .15-.20 size plane, but all I had was a .25 on hand. This is a Sport/3D type plane, and flies sort of like a mini Twist. Even with the larger engine, it flies slow very well, but it will haul ***** vertical anytime you ask it to. It has a hatch in the rear of the fuselage, and that's where I put the receiver and battery, and it balances out nicely with the .25 up front. The only downside is the fuel tank is tiny, 3oz or so, so I set my timer for about 5 minutes.
Here's a link to it on Tower's site:
