Air Compressor Repair Tip

When I finally got around to firing up my new air compressor, the drain valve wouldn't open. You're supposed to be able to open it with just your fingers, but I couldn't get it open even with a pair of pliers and destroyed it in the process. And, of course, no receipt, no warranty. Someone suggested that instead of just replacing the valve, I should put the new one on an extension so that it would be easier to get to than it had been at the original location on the bottom center of the tank. So, after a trip to the home improvement store to get all of the parts, including a new drain valve, I was ready to repair it for less than what the manufacturer wanted for a replacement valve.

Sensenich Introduces New Rotax 912 Prop, Small Lycoming Version Coming Soon

Sensenich Propeller announced a new composite three-blade, fixed-pitch, ground-adjustable propeller last month that uses an innovative pitch-setting "slug" said to greatly improve blade angle accuracy. Called Precise Pitch, the replaceable cartridge sets the individual composite blades' angle in the two-piece hub. The composite blades have a full-length metal leading edge for abrasion protection.

The three-blade is intended for the Rotax 912, 912S, and 914, but Sensenich continues development of a larger version intended for the Continental O-200 and IO-240 as well as for the Lycoming O-235. Sensenich is also expected to announce a version of this prop for the Lycoming O-320 at next month's Sun 'n Fun Fly-in in Lakeland, Florida.

Prices for the three-blade have not been set, but the smaller versions of the two-blade prop with the new pitch-change mechanism start at $2556.

Kuntzleman LED Landing Lights

Kuntzleman Electronics introduces the latest addition to its LSA and Experimental line of aircraft lights called LTR, which stands for landing-taxi-recognition. The LTR consists of nine bright LEDs, focused through special lenses, resulting in a white beam of light that has been measured at 2.5 times the brightness of a 55-watt halogen lamp (while drawing a third of the current) and 1.5 times the brightness of an HID lamp at about the same current, the company says. Powered by 12 to14 volts DC, the LTR draws only 1.35 amps. Its dimensions are 3 inches in diameter and 1 inch deep, and it weighs less than 6 ounces. If you want it to flash on and off, you can use an LED flasher from your local auto parts store.

The price is $234. For more information, call 610/326-9068 or visit Kuntzleman Electronics
