That's a new one on me! Postcuring raises the glass transition temperature...only. At any Tg, if fully cured (like after a couple weeks), adhesion is your basic "tooth adhesion," enhanced by abrasio
which second and at A transponder transmits for only 21.3 microseconds and only when interrogated by ATC. Therefore, even though high wattage, there's no harm even a foot away according to data publi
cryptic I think the problem is the worst-case assumptions they need to make, then in-house counsel add a foot ; then outside counsel doubles the result! In addition to making no assumption as to how
? if yes, were to find it ? For a 1/4-wave "whip" type transponder antenna, no. For a dipole type you buy (Archer, for example), no either, unless mfr says to. For a dipole you make, yes, but one is
It's a restriction when cold, so you can't put it in the line coming --From the sump. The only place to put it is in the supply line to the oil pump, but still a restriction when cold. For purposes
At comm frequency, the longest run of RG400 in this size aircraft will give you only 4% gain in signal. RG-400 is supposed to have greater longevity, but RG-58 should last about 20 years. IMO, a wast
That's where I connected the ground, but a good point on the stress in operation. Only one bolt, though, so maybe it untorques just a little. I drilled a hole in each head and nut anyway, and safety
Oh, my... How much boost is available beyond the regulated max of 39 inches? Good thing I have a digital MAP sensor + digital panel meter -- guess I should add an aural/visual alarm to that now! The
coated aluminum, (that means it's easy to solder and doesn't corrode) But you don't want green-turning, bare copper shielding in aircraft RF cable, or you'll need a gas-tight BNC connector. Also, dou
it? Appears no doubt their VHF antenna is a straight leg dipole, whose length has to be a compromise between COM and NAV frequencies. The straightness of the legs is also not what you want for best
A question I have is whether Europa's citing of only one incident involving a plane with several "landing mishaps" is to be taken literally and no more, or are they in retrospect concerned over the i
No problemo here in U.S. Our policy wording controls, but I'm sure at most they say you need only comply with FAA rules for amateur-builts. Those rules do not require any "mandatory" mod be made, bu
I can agree there, if one will be able to feel the friction. Especially if one doesn't fly a lot of hours, it seems the counterweight will be in a permanent, "frictiony" rust condition. I would have
I think I'm beginning to understand. There is considerable inertia in the counterweight, and a few good whacks to the tail in occasional hard landings would put the lower arm components in compressio
That will tell you whether the battery is being charged, but some may prefer reading only total load on the bus. However, reading the latter will not tell you if the battery is discharging because of
rectifier? Mouser.com does not have minimum order $$. You want computer-grade aluminum electrolytic; 22-25,000 uf, 25-35 volts. Order a chassis mount flange while you're at it. Fred F.
I will bet if you put an oscilloscope on it -- with battery connected and engine running -- you will see negligible difference. I believe the capacitor's purpose is to prevent Rotax regulator damage
of is It's common on PC-mounted caps to mark only the negative in some way, so black with a stripe sounds good for that. See if mfr has a web site with its data sheet. Failing that -- got muiltimete
alternator?) My method is to record test transmissions at home, using my scanner and voice-activated, digital recorder toy. In addition to mix/sub as Nigel suggested, try alternator on/off, low/high
Hmmm. We have 5.5 watts flat (impressive on the flat part) out the back of the box, into a dummy load. With antenna instead of the dummy, we have whopping watts on extremes, and a sharp dip over jus
