Angle of Attack (AOA) Sensor for Small-and Mid-Sized Aircraft

Small- and mid-size aircraft can now benefit from lower power requirements and smaller size of the 4239-01 angle of attack (AOA) sensors from SpaceAge Control. Designed specifically to meet the needs of commuter, business, and general aviation aircraft, the 4239-01 AOA sensors provide:


100 W maximum power requirement (in-flight, continuous)
1 lb. (454 g) weight maximum
Deicing capability per TSO-C16A and BSI 2G-135 (Section 8.7.2)
Electrical angle of -30 to +45 degrees
User-specified electrical angles optionally available
Heated vane and sensor case

The products are a direct off-shoot of the SpaceAge Control's 30+ year heritage in producing angle of attack sensors for flight test aircraft.
"Customers asked us to supply an airflow sensor designed with smaller size, lower weight, and, most critically, lower power draw," stated Tom Anderson III, CEO. "To date, the 4239-01 product has exceeded the design requirements to include a severe deicing test."

Established in 1968, SpaceAge Control is an ISO9001:2000/AS9100B-compliant company leading the air data and displacement sensing industries with stock and engineered-to-order products. Located in Palmdale, California USA near Edwards AFB, the Skunk Works, and Mojave-based Scaled Composites, SpaceAge Control's high-precision and durable products are used by over 200 companies spanning the globe including aircraft manufacturers, racing teams, vehicle manufacturers, and motion control-oriented OEMs.

G2 Ergonomics Introduces New Version of Motorcycle Throttle Tube Design

G2 Ergonomics releases their latest motorcycle innovation - the G2 Delrin Throttle Tube which offers riders the proven G2 control cam options with new Delrin bushings. These bushings eliminate aluminum to aluminum contact for a throttle feel that rivals a ball bearing - yet won't corrode and freeze up like metal bearings.
With professional off-road champions like 8 time National Enduro Champion Mike Lafferty using G2 products, it's no wonder that others are catching on. The new G2 throttle tubes are a vast improvement over stock tubes - offering riders more throttle control resulting in faster times, improved rider stamina and smooth operation. Delrin is lightweight, low-friction, wear resistant and self-lubricating -- a far superior alternative to ball bearing tubes which degrade over time.

Sam Wancket, co-owner of G2 Ergonomics, says, "In the future, all our tubes will include the Delrin inserts, the response to them has been great."

G2 Ergonomics burst onto the motorcycle performance market five years ago when co-owners and riding buddies Sam Wancket and Gary Gibbs were discussing how to improve lap times on the track. They prototyped and developed the G2 throttle cam system which gives riders the option to change cams based on riding conditions. With overwhelming response from the base of riders out there, they have expanded their product line to other markets such as street, ATV, and Harley Davidson.

G2 has made their mark on the motorcycle performance market with constant product upgrades and innovations. With the G2 Quick-Turn Throttle tube and Quick-Turn throttles for Harley Davidson, they show no signs of stopping either.

Riders currently using G2 products are Mike Lafferty, Grant Langston, Paul Whibley, Broc Sellards, Yamaha Supermoto Team, Paul Edmondson and John Dowd. They are planning the release of more products this year and early next year. We can't wait.
