That looks like the Graupner kit. I had one that flew with the brushed Speed 400's. A great flying bird and the sound of three motors (even electric) is awesome. As I recall, the build was a bit tough as the die-crushing was pretty bad.

Lost it when somebody snuck up behind me and tapped me on the should. I about jumped out of my skin and lost sight of the plane. There wasn't enough left to pick up )-:
