Engines were selected through OpenRocket simulations. I am going to rerun now that I have actual weight.
Help Support The Rocketry Forum:
Just ran new simulations on the 3 engine cluster.
Engine Altitude (ft)
A8-3 89.4
C6-3 259
D12-3 324
Hopefully there will be a June club launch so I can see how the reality matches up as there will be a FlightSketch Mini on board.

Pig Soooiiieee!!
Good stuff. 
Primed, ready for painting.
Painted and ready to go out to launch.
Not a perfect flight on 3 C5-3. I believe I can repair the upper half and will relaunch on D12-3s.

Link not working. Sounds like it was interesting. Can you fix?
It works for me. This was taken from the full movie of my launches that day. Try this link:

If you made one with two spheres side by side, would it be a buttnik?
This is my Sputnik. Also 12 inches in diameter. Started with a hollow 12" plastic ball. The antennas are removable for transport and repair. It weights 41 ounces. The motor mount is removable for display. It has a 29mm x 15 inch HPR mount. Thrust curve predicts 326 feet on a AT H-115 with a 3 second delay.

Thanks.Pretty cool
Has it flown yet?
Not yet. Waiting for the right audience.
But everyone will remember how cool it was.
