(Paul Rice) ________________________________ Message 1 _____________________________________ Time: 06:46:55 PM PST US From: "Bob-tcw" Subject: RV8-List: TCW Technologies products Fellow RV builders, Just a note to let you know that the new products we had on display at Oshkosh are now available and in stock. We introduced two products: 1) The Intelligent Power Stabilizer (IPS) which allows critical equipment in the plane, such as GPS, EFIS and engine monitors to be up and running before and during engine starting without the need to carry an auxiliary battery. Additionally, based on feedback from the show, we've introduced an 8 amp model of this product as well. 2) The Intelligent Lighting Controller (ILC) which allows remote, electronic switching of the primary aircraft lighting circuits and includes the wig-wag function as well as dimming control of 3 lighting circuits. All the details are available on our web site. www.tcwtech.com As always thanks for your support Bob Newman RV-10 (40176) TCW Technologies, LLC. ________________________________ Message 2 _____________________________________ Time: 06:48:31 PM PST US From: Matt Dralle Subject: RV8-List: Question On Low-Pressure Brake Lines... Dear Listers, I spent a lot of time staring at those plastic brake lines for the low pressure side and just didn't like a thing about them. Just imagine if one were to break and what a mess all the brake fluid all over the cockpit would be like. After some thought, I came up with the following system for the low pressure feed. I used standard AN 1/4" fittings and aluminum tubing to bring the fluid from the reservoir to a tee fitting and then to bulkhead fittings that connect to standard Aeroquip hoses to the master calendars. Yeah, it was a little more weight, but the peace of mind is worth it. But here's my question. Notice that on the back side of the second bulkhead, I kind of looped the tubing up and around the hole for the vent. This also positioned tee fitting nicely to feed the left and right sides. The top of that loop is maybe 4 to 5" higher than the top of the reservoir, though. Is the flow from the reservoir to the master cylinders suppose to be basically "gravity fed" or is the "pump" action from the master cylinders all that is necessary to keep the tube and master cylinders full?

Hey Matt=2C Your work looks great. To the best of my knowledge=2C the reservoir should be above the master cylinders. I have been using the small resevoirs that attach to the top of the master cylinders with no problems. Have you given them any thought?
