Then I realized #1 that I had already drilled the inside flashings to the canopy frame. I don't know how I could manage to hit those holes with a new flashing; and #2 I studied the back side of the top flange and it was nearly as ugly as the top! I really had to pound those flanges to get the curve I needed. I have now coated the mangled flanges with JBWeld and sanded them down to an acceptible appearance. There really must be a better way!

My current plan is to use a steel anchor, possibly bolted to the tunnel with a doubler (larger than the zenith mod), and with the doubler being larger, it is riveted to the tunnel in addition to being bolted to the anchor. This would spread loads over a greater area on the tunnel and I am thinking the bolts would be less likely to pull out. What say ye, list? The other day I bought a cheap lawn tractor battery and hooked it up to my electrical system. I flipped the battery master expecting smoke, and heard my turn coordinator spool up. I flipped the strobe light switch, and that worked. I turned on the ICOM A200 expecting smoke for sure, and tuned in Milwaukee approach control. I heard transmissions coming in loud and clear. Even though the 701 will be vfr day only, I hooked up the lights to the gauges and put them on a dimmer, and that worked. I was quite please, as you builders know, it is not that common for that many things to go right in a row. By the way, if any of you are going to install the ICOM A200 (which in my opinion is about the best deal in a panel mounted radio out there), if you want to use the internal intercom and the push to talk features, you need to request a more detailed wiring diagram from ICOM technical support. The instructions that come with the radio are not detailed enough on how to wire these features. The additional instructions also tell you where to get the right PTT switch.

After that the beast had a personality and was a living force. Only increased when the engine coughs to life and the purring power of combustion and movement engenders living and supernatural energy. When she flies and lifts you up and around the ground you feel like you now have a partner in defying the natural powers of gravity. Sounds all boogie woogie voodoo right ? Course maybe not; Best to you and congratulations on this big step.

What really has blown my skirt up over these failures is the fact that I HAD a crash in an RV3, the restraint system did NOT "give" (as has been suggested by some that this system is designed to do, BS I say) and aside from some world class bruises from the seat belts, I was uninjured. I DIDN'T hit the panel. I demand the same thing from this airplane. Everything can be improved and this area has shown it can stand some. MY belief is the tunnel is NOT the place to bet your life,or your daughter's pretty face. It's a piece of 025 alum that does have some shape to it making it more suitable BUT it does not match the "robustness" (is that a word?) that the gear tunnel has and THAT part is VERY close so that's what I'm using. To answer your question, a larger doubler and bolts improves the situation but to what degree is unknown. Worst case I guess is 2 guys that are each over 200#, that will put a LOT of load on the tunnel and how IT is attached. I have a test fixture left over from an amphib design project I did a long time ago that I'm rigging up to do some pull tests on a few pieces of 025 in the shape of the tunnel. In the pictures I post showing the results I'll have some various colors of Scotchbrite in the background so everybody feels included and I remain politically correct.

I installed this radio in my airplane and it works very well . Dr. Ed will get some use from this link you posted as he is cosidering the A200 also. I used a PS engineering intercom and it works very well with the A200. I thought the A200 intercom function was very limited and I didn't really ever figure out how to hook it up.

I don't believe the heat of the engine is the problem.

I have an item on my Annual Condition Check List to remove the bolt. clean all the wire terminals at that location every year. No continuing problems. I did have a later problem where the engine would not shut down. After much trouble shooting, it was decided that the problem was an OPEN in the ground wire inside one of the very expensive Ignition Units. Kerry at Lockwood Aviation suggested breaking into one of the hot leads to the faulty ignition unit and run it through a switch in the cockpit. It worked great and continues to do so. Cheaper than buying one of those expensive Ign units.
