Replacing undercarriage suspension bands

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...

Re: Nipper composite fuel tank

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...

Nipper composite fuel tank

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...

Re: Fuselage Fabric

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

Re: Fuselage Fabric

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...

VW engine mounts

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...

Brize and Oxford airspace grab

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...

Re: Nipper trailer

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
Best Wishes

Re: Nosewheel , tyre , inner tube wanted .

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...

Re: LeBurg ignition installation

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...

Re: LeBurg ignition installation

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...

Re: LeBurg ignition installation

Hi Neil, Thanks for your post and apologies for the tardy reply but I have been smitten by the Christmas lurgy which hits in the week before Christmas when I still haven't been out to get presents or to post any cards! I am well into making the crankshaft adapters. I'm making a batch of three; one f...
