Unit specifications: Manufacturer: SKF Model: CATL 33X150X1/C12C Part number breakdown: L: Motor mount -Left but can be switched to right - 2 screws 33: Aluminum tube, sliding screw 150: Stroke length in mm (5.9") 1: Gear C12C: Motor 12v DC Specifications: Closed length: 300mm (11.81") pin centerline to pin centerline Extended length: 450mm (17.72") Mount: 12mm clevis on motor end, 12mm hole thru shaft on actuator end Max current draw: 18A Weight: 5# Dynamic load: 3000N (674.4lbf - that's right - 674.4lbf) Speed: 13-10mm/sec (0.51-0.34"/sec) Source: Surplus Center 1015 West "O" Street P.O. Box 82209 Lincoln, NE 68501-2209 1-800-488-3407 Part number: 5-1228 (Page 119 catalog 271) Pricing: $59.95 + 1.95 handling + shipping from Lincoln, NE (Shipping weight: 6#) For those who want to use a linear actuator on their landing light (or possibly roll trim, or ....) another source has surfaced. A friend sent me a couple of linear actuators from a '98 Honda Accord seat vertical adjustment. They have 1-1/4" travel, small & compact, weigh about 2#, and are powerful little buggers (far more than you will ever need). A fellow builder and I are mounting them below the seat and controlling the landing light with them (light per plans). The units I got were pulled because of an unrelated warranty issue, he saw them, liked them, grabbed them (he works there), told me about them, sent them to me. I guess they are a high dollar item, but auto recyclers are all over the place and maybe they, or something similar, are readily available. Like I said, for what it's worth -- Steven D.

Better idea, fix (not moveable) lights in nose. Date: Sun, 17 Jan 1999 13:48:54 -0500 From: Bill Theeringer Subject: COZY: Linear Actuators Thanks to Steve for the post with the alternate source for linear actuators. I might buy one just to dissect it. They seem to be cheap enough. I checked my builders log for the source of my actuator and for the information archives it was: Motion Industries 858 E. 5th St. Oxnard, CA 93030 805-487-4877 P/N S12-17A8-04 At $151.11 each in 1992.....Its travel is 4 inches which makes it a drop in replacement and it has embedded limit switches on each end. I built a little sensor box to monitor its position. The panel LED is off when fully retracted, red when in transit and green when fully deployed. I have the same scheme for the electric nose gear and both mains. They are clustered and you better have 4 green on final!

If this is for any of the two options I have listed can someone tell me how the correct way to install them would be. Or tell me where I could get the correct instructions for them Thanks Brian Cozy # 94 .....90% done ready for wires
