Battery, receiver, rotor gears and other things required to make the Roswell Flyer go. A list of component weights is at the bottom.

These are the 4 sets of assembled gears. Each one has 2 very small sets of ball bearings. They are light, strong and VERY nicely put together. The white nylon screws and nuts are used to attach the rotors.

Battery - eight 600AE cells and Sermos connectors.

Garrett receiver

The Garrett weighs 6 grams, 5 channels works very well with my Futaba 8UA transmitter. I modified it to the connector block shown here which is prefer to the stock version that dangles at the end of a pigtail. You can buy these from Dave Lewis at Homefly.com.

Component Weights

Complete carbon frame - 22 grams
Motors (stock) - 194 grams
Rotor gear assembly (4 pcs.) - 30 grams
"Brain" - 41 grams
Battery - 151 grams
Rotor blades (4 pcs.) - 24 grams
Black disk PCB mount - 4 grams
Clear dome - 8 grams
Motor screws (8 pcs.) - 5 grams

Future weight savings program includes:

1 - Relocating receiver to the top of the circuit board.
2 - Getting rid of the black disk and the plastic dome
3 - Replacing the screws with aluminum or nylon ones.
4 - ANYTHING ELSE I CAN THINK OF!
Feel free to send in any other weight-saving ideas.

I learned from working with blimps how the grams add up. Snip off an inch of wire here and here, change some screws, etc, and it quickly adds up to a better-performing, longer-flying craft.
