Not sure what type this is but looks like some kind of custom twins.

Model of Rutan/Pond Racer (2 min 16 sec)

Coolness.

Yikes!

yup... that was impressive.....!

Wow!!
High wing loading on that sucker.
How quick did it come in.

It looks like the wings are actually swept forward. That is some serious speed.

Those engines are called A^3 (A Cubed). I picked one up on RCU not long ago (a 140cc) because the price was good. I never did run it and just sold it locally a couple of weeks ago. I believe they use Sachs cylinders and machined from billet crank case. It was a very nice piece of work. They like to turn fast to develop their power (7k+ likely).

Although the plane looks cool and all, I dont think its hitting 250. Maybe being on film takes the effect away but when your there in person and see an actually 220-250 mph pass its much faster. I always loved the pawn racer.

Maybe some of the USRA boys can jump in here. Looks and sounds like they are running alcohol at minimum like the unlimited engines.

I don't know any exact details of this model but those engines are A-cubed for sure like DKJens mentioned. There was a time when these motors were pretty hot in USRA Unlimited racing but the only one I've seen in the past couple of years was on one of Keith Koeppels NA-50's. And since they were used in UL, they certainly used alcohol fuel. So I assume this Pond Racer does too.

Maybe some of our left coast USRA guys have seen this bird around and can give more specific details.

FYI- Years ago, I was at Scaled Composites (Burt Rutans "skunk works") and was taken into the hanger to see the full-scale Pond Racer. All I can say is that the hair stood up on my arms! That thing just "oozed" speed! Burt had designed it for a man named Bob(?) Pond as a Reno Unlimited racer (in the advent of aging warbirds that won't last forever). It had some turbocharged Nissan GTP race car engines as I recall. It flew at Reno but never got up to its true potential due to some engine-related issues. And, unfortunately, it utlimately crashed, killing the pilot. Again that was reported to be due to engine problems that led to an off-field landing.

What a cool plane it was....and the model does it justice!

You can see on the video that the engines have glow plugs installed, so definetely running glow. The A Cubed engine I had, had a single carb. crank case reed intake set-up and CH ignition.
Here are a couple of Pond Racer photos I had on my PC, Hello Dolly!!!!!!!!!!!

SWEEEEEEEEEEEEEEEEEEEEEEEEEEEET!!

I want one!

Very cool, and quick, doubting 250 myself. I saw a person at a jet rally accidentally break 212, and she was a honkin' now...
