Check the 4 stroke Briggs and Stratton conversions used by hovercraft people (and crazies that race lawn mowers :shock: ) Complete with belt reduction gear you are looking at 40HP at about 2200 propeller rpm and a weight of ~ 100lbs. This won't be much less thrust than a 1600 VW at 3400 rpm, if at a...

Once again tapping into the Nipper site knowledge base! I have the aircraft up on trestles as it makes it more stable for trial fits of the engine as I replace the Peacock style mags with a Leburg electronic set up. Consequently the undercarriage legs are 'dangling' so I shall take the opportunity o...

Hello ragson. That is a very interesting website, I'll certainly chase up some of their paint products. The specialist composite tank repair product isn't suitable for my purpose as it is essentially a sloshing sealant and I'm not happy with using sealants on a tank which has started to fail. I cann...

I've tried the LAA forum and even emailing LAA engineering with no response so I thought I try here. My fuel tank has developed a leak along a riveted seam. I've been searching for a composite system compatible with E5 mogas in order to lay up a fuel tank. The most likely candidate I've found so far...

That's one of the advantages with Oratex - significant weight reduction and no post covering finishing required.

If I were considering recovering my Nipper I think Polyfiber would be the process of choice. It is well proven and the materials seem more pleasant to use than the Ceconite process. I've not used Polyfiber but I have done several Ceconite covers, the only problem I have is that I now have a stock of...

Hi All, It is clear that the engine mounts on my aircraft aren't original Slingsby manufacture, they look as if they came with the Rollason Ardem which was originally flown on a Taylor Monoplane. Can anybody tell me the measurement from the engine mounting flange (not the gearbox locating ring) to t...

Just a reminder that it is getting to the last minute to submit an objection to the airspace applications by Oxford and Brize. A shortlist of information if you haven't seen it already: http://www.lightaircraftassociation.co.uk/2018/News/brize_norton.pdf https://www.ftnonline.co.uk/2018/03/19/courti...

Safer propswinging article already sent to LAA mag as a result of the two aircraft runaways described in December issue

That's the photo I saw many moons ago. It looks like the cover price of the mag has crept up a bit since then!

As it happens possible hangar space problems may force the re-incarnation of the Nipper Tipper to keep the floor area down.

Here's looking forward to 2018

My mk3, and the mk3 drawings, uses a 400 x 4 tyre and associated tube. This is a common size and aircraft tyres are readily available from the usual aircraft suppliers. TOST are the gold standard, and correspondingly expensive. I think the 'double rib' nosewheel tyre shown on the drawings is obsolet...

Hi Neil, Thanks for the information. I initially assumed that the Leburg drawings would just be a copy of the VW flywheel groove and O-ring but became confused when it came to cut the groove. Two things still confuse me! The O-ring inside diameter is given as 56.5mm which cannot be correct as that m...

Hi, and a happy New Year to Nipper forumites Can anybody tell me how they fitted the crankshaft O-ring seal in the Leburg crankshaft adapter? I've got this part on the lathe and cannot reconcile various dimensions given on the drawing which is supplied with the Leburg kit from Skycraft. The quoted O...
