Lasar Ignition came on my new Lycoming Engine from the factory. A screw on the distributor cap backed out of my left magneto and it took 364 hours of working back and forth to destroy the magneto. Unisons service manual doesn't even have you look at the points until 500 hours. After sending him pictures of the Magneto, the Service Representative at Unison said that it was beyond the warranty period and couldn't possibility be a manufacturing defect and they wouldn't pay for anything. This all started with a 300+ mag drop on the Left Magneto. While looking for the cause of the Mag drop, I removed the ignition lead caps and found the left magneto distributor cap moving up and down. Danny King and I took the magneto apart and found that one of the screws on the distributor had backed out and had been working in the hole in the case. There was plastic, carbon, and aluminum dust all over in the magneto. Lessons learned: Unison doesn't stand behind their top of the line Ignition System. None of their dealers stock the 4771 magneto meaning minimum of 3 weeks to get one. The only way you can get one sooner is say A.O.G. and the distributor can have it drop shipped from the factory overnight for another $45. Aircraft Spruce had the lowest price of $601 plus $150 core charge. I have bought my last Unison Product. If anything else goes wrong with the Lasar system, I will remove it from the airplane and install P-Mags. A P-Mag system is less than half the cost of the Lasar system and being a new company, I'll bet you they would be very interested in a premature failure of one of their components.

And now for the optional rhetorical whining question ... why does Van's have you run the pitot tube right next to the spar so that it slams right into the center section bulkhead ???

I have had nothing but excellent support from Unison of the LASAR's I have owned . My first LASAR was on a 1976 Grumman Tiger. I bought the Tiger with the LASAR already on it and it was about 4 years old. Somehting began making a slight ticking sound, kind of like a dry tachometer cable, and I thought it was coming form the mags. Unison sent me brand new mags without charge. This cured the sound problem. I have since purchased 2 other LASAR systems for other airplanes and have nothing but good things to say about Unison LASAR and their customer support. I suggest that you find another contact at Unison and try again.

Riveting the RV-7/9 side skins to the baggage bulkhead/bottom skin curve INNOCENT GLOBAL 0.0000 1.0000 -4.4912 --> RV9-List message posted by: "Merems" Fellow builders, I am going to be riveting the side skins on in the next day or so. I am a little concerned about the 5 or so rivets that attach the side skins to the bulkhead at the bottom skin of the bulkhead where you form the bend near the F-623 rib. I have bent the tabs as best I can and I know from experience this could be on of those areas that you may dent the skin during riveting. Any tips for riveting this area? How many of you used bind rivets in this area? Paul ________________________________ Message 6 _____________________________________ Time: 08:13:23 PM PST US From: "Douglas A. Fischer" "RV Matronics List" Subject: RV9-List: Chrome-plating for Gretz Heated Pitot? --> RV9-List message posted by: "Douglas A. Fischer" Does anyone know a source for vacuum-metalizing for retail customers? I was thinking that may be a safe way to put a chrome finish on the black plastic Gretz heated pitot to match the mount. I think the old chrome dip-in-chemicals route used to plate metal would damage the pitot.
