Acrylic plastic transmits about 92% of the visible light and polycarbonate transmits about 89% (and most glasses are in the same range) so whichever material is in the windscreen (and it is very like
A common misconception is that fuses or circuit breakers protect devices. Not so. The protection is for the wire, or more precisely, the insulation on the wire. A given wire-insulation combination ca
An additional assist comes from altitude. The boiling point decreases with altitude so, for example, at 6000 msl pure water boils at about 94 deg C, at 8000 msl 92 deg C, and at 10000 msl 90 deg C. O
No, no, not deliberately, but ONLY if the coolant manages to get into the oil - I should have made that clear. Atmospheric moisture, as you clearly understand, is quite pure, except here in the LA Ba
First for the easy part. Bolts through the firewall, especially when a washer is used on both sides of the firewall so there is a tight seal, will not allow any flame to penetrate. I consider this go
Jeremy, you apparently have a more recent version of the manual. My version, and I suspect Dave's version may be the same, has no mention of this minor detail. The first two PAGES in Chapter 9 of Iss
While I don't think that this "trick" would cause any harm, and it certainly is relatively effortless, a dent is by definition deformation beyond the elastic limit of the material, ergo, the dent is
I heartily agree with Fred. I've mentioned before on this forum my experience with the plastic hydraulic clutch line on my long gone Lotus Elan - plastic line ruptured, fluid leaked on exhaust, car c
Murphy's Law: If anything can go wrong, it will. Corollary: At the most inopportune time. Probably the best example of how Murphy's Law works is aircraft vacuum pumps. These evil devices are guarante
Something is suspicious here. According to Rotax the engine must be up to 1200 RPM in order to start, so let's do some math. 1200 RPM divided by 2.43 (the gearbox ratio) is 494 RPM at the prop. If we
In re: reamers I suggest that you use an adjustable reamer such as McMaster Carr (http://www.mcmaster.com/) part number 2987A12. Best regards, Rob Housman Europa XS Tri-Gear A070 Airframe complete Ir
That's exactly what I did (but I'm not yet flying). This duct is relatively well sealed against CO intrusion but of course without actually flying I can't be certain that his is a valid assumption. N
Acrylic, chemical name polymethylmethacrylate, (trade names: Plexiglass, Lucite) will yellow with age but polycarbonate (trade name: Lexan) will remain clear and colorless, assuming you start with th
Ever since Erin Brockovich (the person and the movie) hexavalent chrome has had an extremely bad reputation so you may find it impossible to purchase the zinc chromate. It works, if you can get it. A
Mod 72 provides added strength, in particular in bending, by adding thickness to the wall of the tube. It is the added thickness that provides the additional strength and because there are no forces
Being a Tri-Gear builder I can't comment on the mono, but I can correct a minor misunderstanding regarding aluminum (aka, aluminium and, rarely, Dural). Aluminum alloys work harden; that is, when def
Ah yes, but if one REALLY does the math, there can be only one conclusion, viz., this can not work as suggested by Steorn because it violates the (universally accepted and so far absolutely inviolate
You are on the right track because Alodine and zinc chromate each provide a good basis for making coatings stick to aluminum. Do not try painting aluminum without pre-treatment because the naturally
Agreed, Ron, there are several ways to do the job. My main point was that aluminum MUST be treated in some fashion in order to make any paint adhere. In your link to dplf-p-196 the footnote for paint
Jos, you might be right about the TCU software but for those who want to try running it under Windows XP (I haven't) the attached file tells how to go about it. This file is a few relevant pages copi
