Hey all,Two questions.Firstly, I glassed my cowling over a waxed mold and now want to add a layerand glass some stiffners to the inside, but there is a fair amount of waxresidue on the inside of the cowling from the mold. I've tried mineralspirits, MEK and Formbys furniture refinisher and nothing really removes itwell. Was going to get some acetone, but thought I"d send it out to seewhat you guys would suggest.Secondly. What do you guys think is the minimal size a trim tab on theelevator could be to work? Don't think it takes much.Thanks,Douwe________________________________________________________________________________Date: Sat, 22 Jan 2011 19:18:35 -0800 (PST)

Douwe:I agree with chuck's post on the quarter wave calculations and the need to mountyour antenna at the center of the "ground plane". There are ways to overcomethe length issue (nearly 2 feet) such as coiling a portion of the wire (thatis essentially what they have done in your handheld's rubber ducky antenna),or by folding it back onto itself (without touching itself), but you will likelydegrade the effectiveness of the element if you do (create directivity, reducerange, etc.). You may or may not know, but your hand held is likely feeding your signal througha BNC connector. You will want to get a BNC cable in order to feed your antenna...don't convert from one connector type, to another, then to a cable, thento another connection in order to get a signal to your antenna. The fewerthe connections the better as each additional connection results in some levelof signal loss, known as a bump in the electronics world. Also, keep your feedline(cable between your radio and antenna) as short as reasonably possible.I'm not suggesting that you run a tight line straight to your antenna, butdon't coil a 50' cable under the seat either. Aside from the obvious weight considerationand the chance that it flop around, it will also attenuate (reduce)your signal unnecessarily. You should be able to make this connection witha 6, 8 or 10 foot cable, which are readily available from a variety of sources.I've inserted a couple of BNC type connectors below so that you know what we aretalking about. If you need any help at all, feel free to shoot me a note.--------Mark ChouinardWings, Center Section and Empannage framed up - Working on FuselageRead this topic online here:http://forums.matronics.com/viewtopic.p ... ttachments: http://forums.matronics.com//files/bnc_ ... ___Subject: Pietenpol-List: Re: wax solvent and trim tab size

All of my turnbuckles are in line with the slip stream - not crosswise. What can we do to reduce the drag on those?----- Original Message -----
