300Kg single seat is the Brit/Euro microlight standard, along with the 450Kg twin seat. 544Kg single and 600Kg two seat is the AU/NZ Microlight standard.

Just visit Burnsco ( I think they have Aussie branches ) and get a RV/Motorhome dual battery isolator circuit. Pure Off-The-Shelf self contained electronics. hook two leads to the main battery/alternator circuit at the main battery terminals (to charge the secondary from the main), anything to be isolated and run separately off the second battery goes on the Other set of +/- leads where they attach to the second battery terminals. They allow a few dozen amps across from the main battery and nothing back the other way, enough to charge the secondary and run a few low draw devices. They're used so if you flatten the house lights in the campervan you don't flatten the starter battery, If the main battery voltage drops to a certain point they stop allowing current through leaving enough to run the starter motor, so you can still start your motorhome after falling asleep with the lights on rather than flattening both batteries. They also isolate the secondary batteries from starter draw since deep cycle house batteries aren't made to deliver lots of grunt for a short while like a car battery,but rather a low draw for a long time, so having them hooked into the starter circuit would kill them in short order. Exactly what you want, just hook the second set of wires to one DC Mag instead of your cockpit reading lights. The ones I have seen are about the size of a couple of packs of fags, and a couple of hundred grams at most.

But between the alternator and the electronic circuit is a rectifier. So all the electrical system sees is DC, pulsed DC, but still DC. http://www.bcae1.com/charging.htm

I'm guessing the stainless sheets are the thin cheap generic stuff the supplier had in stock for less hassle than ordering in airworthy known-composition reputable aluminium with the attendant pricing? The chromium steel used in kitchens as splashbacks there instead of tiles in low end homes? No point in using the good stuff for a Proof-of-concept mockup I guess. Not when those pennies saved can be used to buy a beer or ten.

At least it was a wasp, not a bee. wings, stinger, close enough for most "Journalists"

Ah well, that chokes off self service. Most standards for electronics just run on about voltage, emissions, permitted variances and the like. Nothing about who can service them, otherwise how would HAM radio guys be able to build their radios from kits...

If the CAR is right then, putting your own statement of battery fitness on it would count. Change the battery yourself and take it along to a trophy engraving shop and they can engrave the fitment date and new expiry date(+5years) neat as you please. If you're happy flying in a self-built plane with a self-maintained engine then why wouldn't you be happy with a self-rebatteryed PLB. It all fits in as part of the same Ethos.

Photoshop and a laserjet printer?

If you don't mind voiding the expired warranty, you can usually get kits to change the battery yourself. I have a SUUNTO Gecko dive computer for my SCUBA kit, battery died and they wanted it sent back to their HQ to have the battery changed at ruinous cost, $19 USD later and I had a kit of battery, grease, O-ring and specialised propriety screwdriver. The PLBs I have seen look much the same, do them carefully, set things in place properly, don't nick the seals when setting them, ensure the grease or sealant is applied correctly and you'll be golden. Still working fine years later. In fact it's about time it got another change.

Why do Aussies push sheep towards cliff edges? Because then they push back harder...

I've seen it for Turkey... which given there's a non-country namesake out there in common use, could explain it. Who wants to eat a country for thanksgiving? How many write about their cutlery with a upper case? Put the China on the table...? You'd need a big table.

I just came from HBA, same thread there, 2 pages... here 8 pages... A pretty garrulous lot here...

Looks like it's missing wings, delta or otherwise. I'd class it as a lifting body.

Poor dog! That was MEAN! Go give it a nice bone and apologise!

An interesting titbit about manufacturing pistons is the good ones are not machined round like on a lathe but oval like a camshaft lobe. Look at the underside and you will see where the pin travels from side to side has significantly more meat to the forging/casting while the skirts to the sides where the pins are not are much thinner. A good piston manufacturer grinds them oval so the wrist pin sides are ever so slightly narrower than the bare skirt sides. That extra volume of aluminium means those sides expand slightly more, so a round lathed piston would expand to become oval, while a cam ground oval piston expands to become round in the piston bore.

Is that better or worse than a Ladder Frame? I thought you were making a Plane, not a TARDIS.

Anything sold in Russia/CIS must by law be GLONASS capable. And a market of 130 million or so it worth sticking a few chips and an antenna in for. esp since the chips are already out there from third party sources.

I'm just waiting for my free trial beta test Flykea flatpack to arrive...

Yeah, it is intended to be funny, Like Bexr I have spent time in China, on more than just a tourist trip, with friends over there who I still keep in touch with and some who even visit here in NZ when work brings them this way. It might surprise you but I have tucked into chicken feet myself, with the right spices they aren't bad, a bit bland and with a geletinious texture, but even to foreign preferences they are quite edible. Even chinese I know will joke about them to foreign friends. Oh yeah, now THAT stuff is just plain inedible! You should get your hands on some NZ Marmite instead! Back to the original topic, Bexr... didn't the plan originally have diagonal bracing slipped into cutouts in the extrusions down the sides, not just around the join of the bottom fuselage bars? are they no longer needed?

Give them a reward!

Cat is cheap, met once a week should keep him happy, plus a bag of chicken feet on holidays.

Looks like one of the FREMM frigates? The radar looks like the french and italian shorter ranged unit that shares it's origin with the more powerful unit on the Type 45 before Britain pulled out of the common euro frigate project since it was ending up Med-centric (shorter ranged, shorter radars) than the world wide global roaming design the RN needed.

I went to the same primary school as the son of Max Clear of Micro Aviation/Bantam B22, Maxs wife was my Teacher of the Deaf who came to the school several times a week to act as a teacher aide. She got Max to take me up in a Bantam a couple of times.

The SH2 WAS bleeding edge when it was new, but it's an old fly-by-cable system dating back before computerised flight controls were evisioned. Remember the SH-2 first flew in 1959 and the SH2G of the late 80s is really only a better set of engines and a glass cockpit on the old strengthened airframe. The U/H/M/S-60 family is 20 years newer and has somewhere around 4000 made of the various different versions, compared to the approx 200 SH-2 helos made. Plenty of off the shelf upgrades to bolt into the SH-60's for the RAN tht have been funded and debugged by many previous users.

Sounds like the SH2 saga, Aussie navy wants a helo that can fly hands off in auto-hover with a crew of 2 and buys low hour second-hand copies of an old design made to fly hands on under pilots control with a crew of 3 and attempts to shoehorn in a non-supported autopilot off their own bat and find they can't do it meaning the airframes sit round for years doing nothing. Turn around, sell them to the RNZAF navy support Sqn for pennies on the dollar who proceed to rip out the botch job and fit the tried and true old system for 3 men as used in their new-built trouble free and now very high hour airframes to the low hour ex Aussie (and previous others) airframes and start racking up the hours in operational use. Meanwhile the RAN goes and buys a bigger more sophisticated design that has the desired capabilities built in from the factory. Imagine how much could have been saved if they had done that in the beginning?
