Default Graupner Race Rat

I've a NIB Race Rat. It is an older design and electric. I am planning on keeping it electric. Does anybody have a good suggestion for battery, speed controller, motor, and prop combo to pull this puppy into the 150mph range. I realize that the wing will have to be beefed up as this is where they usually failed. The fuse also.

I'm open for suggestions. Neu, Mega... It looks like it would have to be a smaller motor as the plane is fairly small. I think that it was designed around a 500 motor and claimed ~100mph.

Nice bird Evan. Looks a bit cleaner than the Race Rat.

An old slope soarer, started out as a modified Douglas Siloehette, 7 years ago I put a .061 on the nose, this year it got the Mega. It's 20 years old... Still flies fantastic.
