Boeing Sonic Cruiser Parkflyer

This is a simple profile model of the Sonic Cruiser concept Boeing developed back in 2000-2002. It's built entirely of BlueCore foam and is powered by two GWS IPS motors mounted pusher-style on the back of the nacelles. Control is provided by ailerons on the aft wing and a full-flying canard. Despite its racy appearance, this model is actually quite docile and easy flying. And due to the very light wing loading, it can easily fly in a baseball diamond-sized field. This model has special appeal to me because I spent three years of my career as a design engineer on the Sonic Cruiser program.

Wing span: 30.9 in
Wing area: 242 sq in
Weight RTF: 10.5 oz as pictured
Wing loading: 6.3 oz/sq ft
Motor: Two GWS IPS with A gearing
Prop: GWS 8x6 slowflyer
Battery: 3s 1000 mAh Li-Po
Radio equipment: GWS R4P receiver, GWS Pico BB servos, 10 amp ESC

Sonic Crusier ESC question

I previously built the Avro Vulcan that was featured in the AMA Magazine. I want to build the Sonic Cruiser. What type of connector will I need to get to operate two motors off of one ESC?

Note you can only use one ESC for two motors if you're using brushed motors (like I did on this model). Brushless motors require one ESC for each motor.

That said, you can use either a standard Y-connector, or better yet do as I did and simply solder the wires together (which eliminates the need for a connector).

Good luck!

Outlet for GWS motors etc

Where can I go to find an outlet for the GPS motors and servos in the United States?

Good question--and I don't know. I haven't even seen a GWS motor in quite some time. The vast majority of the industry has gone brushless. I also don't know what an equivalent brushless motor would be for the GWS motors I originally used, either.....that would take some research. I'm sure there is one, though, just have to find it.

Might have to build one of these to compliment my Multiplex Sonic Liner
