It takes less than .75 inch of travel on the handle to start braking. It has a locking pin in the braking position allowing it to be used as a parking brake which is also very effective. It has enough grab to hold the plane in place during full power a run up. The lever just clears the knobs on the GNS430 when full forward though, no room to spare. -------- Lee N69XS A069 Read this topic online here: http://forums.matronics.com/viewtopic.php?p=494363#494363 Attachments: http://forums.matronics.com//files/brake_213.jpg ________________________________ Message 2 _____________________________________ Time: 04:13:44 PM PST US From: Martin Tuck Subject: Europa-List: Dipole com antenna I'm thinking of switching from an external monopole type com antenna (long rod sticking out at an angle with copper tape in a radiating pattern on the fuselage floor) to a Bob Archer SA-006 dipole antenna. The dipole appears looks like a '3' and made from thin sheet aluminum. This '3' shape is what you attach the coax shield too (ground). The core of the coax attaches to a small insulated aluminum plate in the middle of the 3 shape. Does anyone know how it works (the theory) and does anyone have one in their Europa? How is it?

The tailwheel springs were not very tight and if there was no differential braking it would make for interesting landings unless landing on grass or directly into the wind. Letting the bird sit outside, corrosion would develop on the caliper bore and rust on the rotor. A landing or 2 and the pads would wear, allow the seals to contact corroded bore and seals leak on the bore. If lucky you would get a little breaking with pumping before fluid was gone. What a hassle of changing calipers and pistons. Not exactly "blessed"l but we machined a new piston from 6160 after being frustrated but instead of 1 o-ring groves, machined 2 and put a little silicone grease between o-rings. That kept the o-ring bore for the real deal o-ring clean and worked for us for over 15 years without a glitch. It was a real hazard losing brakes. I always to try and use "blessed' components on type certificated aircraft,l but if something "blessed' endangers my neck, safety comes first. Cleaned and replace O-rings only a few times in 15 years and bore always looked great. My IA was completely impressed. If I have a problem with my Europa piston, that's going to be my plan. Ron P.
