It's one thing to get the accelerometer and altogether another to make it into a useful device. They suffer from drift and zero error for a start... Rate gyros are worse. Even when you have a useful device, the real hard bit is turning the data into something meaningful... Believe me, I know. I'll l...

Nick - Actually it’s a six/nine axis device three linear accelerometers, three rate-gyros and three-axis magnetometer which keeps the rate gyro drift under control. It is based on this: http://www.xsens.com/en/products/machine_motion/mti_oem.php The only problem is that the sampling rate (30Hz) may ...

This post has set me thinking. I have access to some good quality 6-axis accelerometers with integral data loggers. I'll set one up in the Nipper and see what the output looks like.

Dare I ask what they are for?

Thanks for the sensible answer. Is there anything I can do to help?

Good news for my Jodel 1050 project and anyone else with a French 'orphan'. My letter from the CAA arrived today and it has been confirmed that it will be on a Permit. The interesting bit is a note on the back to say that, "A Permit to Fly may be issued with differing Flight Conditions or Maintenanc...

For simplicity, you can not beat a standard boat-outboard filler-cap type gauge (cork and wire excepted). It uses a piece of flat stainless strip twisted through 270 degrees with a needle fitted to the top. The needle is viewed through a window on top of the filler cap. A plastic float with a slot i...

As a more serious response, have a look at combining shorter finals with glide or low-power steep(er) approaches. There are lots of strip flyers who are still hooked on the three-degree drag-it-in type approach. This has the engine at higher power at a lower altitude than a steeper or glide approach...

I have Magnecor leads on my Nipper with Leeburg System (which utilise a coiled stainless steel core) and they work fine. No noticeable radio interference (though I do get a tiny bit from the alternator).

I know thi8s is not really very helpful, but you could always do what they do at Popham. Everyone bimbles around pretty much where they like coming in from all directions and by some miracle no one seems to bump into anyone else....

www.ignitionleads.co.uk can make what you need to order. I have a drawing and a set of lengths for a Tipsy Nipper set if that helps.

A dipstick and watch. The dipstick tells you how much you have to start with and the watch tells you roughly how much you have used. Simple, leak free, cheap, reliable and no less accurate than most light aircraft fuel gauges.

The definitive text on all things nuts-and-bolts is usually regarded as, “An introduction to the design and behaviour of bolted joints” by John H Bickford. At just shy of 1000 pages it’s not exactly light reading. Even in this book, the author regularly states that industry best-practice often remai...

You can buy those blocks ready finished from Barry Smith at Acro engines if he has any left in stock.

Mocal also do a Type J adapter for precisely this purpose, though it is not as neat as the Acro one.
