I'm fortunate to NOT have purchased lights yet. I have been kicking around the idea (maybe out of ignorance) of purchasing an emergency vehicle strobe kit for my wing tips. Can anybody tell me why this would not work (flash rate, power usage, etc.) I am surprised I haven't seen mention of this. There is a small strobe that is mounted inside the headlight bucket on emergency vehicles that flashes. The electronics and capacitor can be mounted just about anywhere. Has anybody thought of this and shot down the idea?

In the nuclear industry we run into it all of the time with spare parts. The solution being we have procebures to take them out of storage and power them up every 6-12 months, to reform the capicitors. Do you have to, no but if you do you improve the odds that you won't have a problem. Electolytic capicitors are still generally considered to have only a 5-10 year life although many last much longer.

When he opened the cowl to check the oil, there it was. Lot better than adding another device or opening on the aircraft.

I found the center of bend of the skin lined up correctly with the centerline of the rib rather than the center line of the radius of the nose as in the manual and drawings. Everything worked out fine apart from this deviation. Anyone else have the same problem? Could there possibly be an error in the manual and plans, or did I just bend the skin in the wrong place?

Results are great, hope to have it flying Jan or Feb. Happy New Year to All!

Ya, like it will be a new year tomorrow... You have probably got the bend a little off. I would not worry about it, it sounds like you are close enough.

What you should do is to put the rear spar channel 7F5-3SP of the fuse prefectly horizontal, then try to offset a little the holes of the rudder hindges to have the rudder perfectly vertical, depends in the twist, in ours making the holes 2 mm to each side of CL was enough. Same happens when you install the stabilizer, one side holes of the angle supports will be a little higher than the other side (no one will see both sides at the same time :-), just keep the stab level with the rear spar channel. Remember, acording to the photo manual, we squared the fuselage in the luggage area with the piece of wood, the tail part should be squared by the aluminum pieces 7F1-3 and 7F1-4. I dont think that your fuse is to twisted to be a problem, only if offsetting the holes doesnt help with the squared tail surfaces, then check the amount of twist in the tail section (degress or distance off vertical) and ask advise to ZAC... maybe in some cases, is needed to make "offset" hindges 7F4-1 & 2 for the rudder, but I dont think any fusselage will end that twisted... Happy New Year to you, your Family and ALL in the LIST! Saludos Gary Gower.

How long should we make them work every time... we have a start booster box from JC Whitney (the one that has the cables in the side) I can make them work mean time the wings are in storage, looks great inside the shop with rock music :-) Thanks once more for the advice. Saludos Gary Gower PS. The ones still in the box, should recieve the same 6 month treatment? Do you advice to make a fake instaltion to make them work twice a year?

I caught this in the cleco stage. I layed out another skin and made sure it was exact. the twist can be due to any of the skins ,sides not being exactly the same, top or bottom skin not congruent, or the ends not properly in line. Once it is rivited it is extremely stout axially and a small ammount can be compensated for by rudder hinge placement and horizontal stab bracket adjustment. Level the fuse at the rear wing attach points and drop a plumb bob from the top rudder hinge to see where you're at, if the hinges wont attach safely to the longerons and maintain a purpendicular relationship to the wing then look closely at the skins. hope this helps.

The position lights consist of an Aviation Red on the left side, an Aviation Green on the right, and an Aviation White tail-light (REF. FAR 23.1389). The anti-collision lighting system is required under FAR PART 91.205(c). There are different requirements affecting different aircraft. These aircraft are categorized by the date of application for type certificate. Home built aircraft are determined by the date of issuance of the Experimental Operating Limitations. The different categories are as follows: ... Aircraft for which type certificate was applied for after July 18, 1977: These anti-collision systems must produce a minimum of 400 effective candela in Aviation Red or White (REF. FAR 23.1397), 360 around the aircrafts vertical axis, 75 above and below the horizontal plane (REF. FAR 23.1401). *The position lights must be wired independently of anti-collision lights. --- > >> Scott,I don`t know about the ones you refer to but I > >> have heard of useing unites salvaged from school > >> buses.Also Great Planes Aircraft sells a neat strobe > >> kit for about $30.One needs to come up with a mounting > >> box (Radio Shack) and a houseing for the bulb.This > >> unit uses a gang of 6 caps rather than one large > >> one.Veary easy to assemble.

So the normal circuit would be in series via the 24 volt buld and when the strobe switch is turned on it would be in parallal . Why a light globe it is just for resistance and cheap. Untried, but as the strobe manufactures have poorly designed products it may be worth a go. If I remember Jim Weir published a strobe design a few years ago . A few years ago there was a stolen formula a huge amount of pc board manufactures were caught with the faulty caps, maybe the same capacitors? You can read a little about it here in adobe pdf file. http://www.ec-central.org/magazine/nov_dec_02/taiwanese_cap.pdf Tony ---------------------------------
