Re: Leburg Honda alternator adapter

That would be very helpful! jimcrawford[DOT]oxford[AT]rocketmail[DOT]com should find me. I recently bought a boring bar to cut the O ring groove but the one I was sent wasn't the same as the one in the brochure and couldn't be used. Apparently the manufacturers had changed the design, an unintended ...

Re: Handheld radio - New purchase & Licence application

After reading the fairly extensive discussion on the Flyer forum re 8.33 handhelds, and in particular the ICOM/Yaesu debate, I bought the Yaesu. The one with VOR and Lithium battery. I have only ground tested it so far but with both the supplied antenna and the aircraft whip I had excellent transmis...

Re: Handheld radio - New purchase & Licence application

Not so, I bought a Yaesu handheld for my Nipper and got the refund (first tranch). The kit is regarded as a handheld, or transportable, radio, all you need is the handheld version of the licence, no aircraft registration is required as the unit could be transferred between aircraft or used on the gr...

Re: Leburg Honda alternator adapter

Hello Chris, A timely posting. I've had to attend to family matters since last March and these have been of such intensity that I decided to stop all aviation activity until they were resolved - just to get some breathing space. All is pretty well sorted now and I restarted my VW/Leburg work a coupl...

Re: Oshkosh 2018

Hi Sam, Thanks for your offer of help. I'd like to tap your font of knowledge but I'm afraid life has got in the way of aviation and I've had to delay my plans for a year. I've been sorting out aged parents, nursing homes and stuff. I haven't flown since March and don't expect to do any significant ...

Re: Leburg Honda alternator adapter

Hi Chris, Thanks for the information, I'll follow up the lead on the VW O-ring part number and see what I can discover. I do have a copy of the original Peacock drawings which show a cut down flywheel but the style used is that for a crankshaft that doesn't have and O-ring but uses a paper gasket at...

Leburg Honda alternator adapter

I'd like to contact anybody who has fitted a Honda 600 alternator to the crankshaft of a VW engine, as described in the Leburg paprework. I have an adapter half made on the lathe and have got to the point where I want to cut the o-ring groove for the oil seal. I cannot reconcile either the dimension...

Re: Lithium ion batteries

Hi Sean, I'm pushing on with this project, I have a set of three crankshaft adapters on the lathe and, when they are finished, I'll be rigging up my alternator test set. As I've mentioned in a previous post, plan A is to write up this whole exercise as a series of articles for the LAA mag and I've j...

Oshkosh 2018

I have a plan to visit Oshkosh with my aircraft in 2018 but have hit a snag which I hope can be solved by the members of the various forums which I shall plague with a shotgun approach to posting in my search for advice. I am a British Citizen with an ICAO compliant private pilot’s licence and medic...

Re: Lithium ion batteries

I’m submitting a mod for my Tipsy Nipper to utilise Leburg ignition with LiFePo batteries. This is outside the remit of SM 14337 (installation of LiFePo batteries) which excludes ‘electrically dependent systems’ such as electronic ignition. Consequently this must be a new mod with comprehensive anal...

Re: Tipsy Nipper C of G

Mike, I can't understand how you put those numbers together. The utility max weight of the Mk11 was always 725 lbs and the aerobatic weight 660 lbs. It was never increased from 660 to 725 to take account of a heavier engine. I find the difference in weight you state between the Stamo and Ardem engin...

Tipsy Nipper website

Any other Nipperists having trouble with the Nipper website? I'm getting an "Internal Server Error" whenever I try to access the site.

Re: Building advice sought

I'm interested (and surprised) by your comment; "Taylor Monoplane (seems to tick all of the boxes but people warn me that it is a dangerous aircraft to fly)" All the information I have, both from print and in conversations with owners, is that the Taylor is pleasant and safe to fly. Who are these pe...

Re: HVLP kit

The more comments the better is my opinion. I'm using the Ceconite system exactly as per the Ceconite manual, if for no better reason that I hear so many conflicting different ways of doing things that RTFM is a more consistant way to work. A few notes on Terry's post. One comment I've heard, and ca...
