Re: Parachute
Hi Sven, I've looked into this and come to the conclusion that I can wear a parachute if I move the stick 70mm forwards and have schemed a mod for this but it's on hold while I get the aircraft back to service. You can get thin packs which carry the contents full length down the back and forward on ...

Re: engine temperatures
Hi All, My aircraft doesn't have any fit yet. My enquiry was prompted by disappearing down a rabbit hole whilst investigating a new exhaust system with silencers fitted. My current arrangement is four short exhaust stacks pointing down. This is the arrangement on the Nipper Mk3 drawings I have and i...

engine temperatures
Good Morning Nipper fans,
Can anybody give me an idea of the oil and cylinder head temperatures they see when flying their Nipper ?

Re: Exhaust arrangement
I won't be doing much bending, that will be sorted by Reef Exhausts, specialists working out of Bicester. My part will be withstanding the painful shock of opening my wallet. Other Nipper folk provided some very useful pictures earlier https://www.tipsynipper.com/forum/viewtopic.php?f=12&t=628 I...

Exhaust arrangement
Hi Nipper fans, I'm preparing a new set of exhaust pipes to replace mine which have probably only got this season left due to corrosion. My old set have the pipes as short open stacks pointing down out of the cowling and this is as shown on the Nipper Kits and Components GA drawing. However it looks...

Re: MK3 nipper bits
That photo explains everything. I wonder why the early units went to the complexity of such a casting rather than a 'Peacock' style installation. I have a very similar casting from a Revmaster conversion. It's about the same depth and has a very similar magneto attachment, although only a single mag...

Re: MK3 nipper bits
That engine confuses the heck out of me! Is that as fitted to a Nipper? That chunk out the back must result in the engine being located about 25mm forward of the Mk3 because all that metal casing won't get past the diagonal bracing tubes in the forward frame. This forward shift would mean the aircra...

Re: MK3 nipper bits
The Nipper is quite tender on the C of G position. The acceptable limits for flight, as laid down on the permit release, lie roughly about the position of the main spar. Fuel is well forward of the spar and the pilot well aft. There are three critical conditions which must be addressed; 1. with zero...

Re: Wing Bolts
Excellent result.
I never bothered to get my old bolts crack tested as they had been installed dry and had surface corrosion, enough to consider them scrap. The new studs were installed with liberal applications of JC54 jointing compound.
Good Luck
Jim

Re: Fitting a starter motor
If you are thinking of adding a starter to a VW engined Nipper then I suggest you investigate the weight and balance implications of the starter, flywheel, battery capable of turning over the VW (including it's mounting structure) and associated wiring. You may find the resulting weight and balance ...

Upper longeron dimension
Hi all,
I need to calculate the compressive strength to failure of the upper longeron. Can anybody tell me the gauge of the material of the tubing?

Re: Wheels
Just to add, my intentions to build a set of hubs was two fold: My 'old style' tyres are serviceable but I have no spares and I was concerned that I could get caught out with a damaged tyre away from base. That could become logistically rather tricky to sort out but the 400 x 4 is readily available....

Re: Wheels
Hi All, I guess this is to get away from the 4.95 x 3 1/2 tyres which are nearly unobtainable. I have been quoted £400.00 each :shock: for old/new stock. Maybe the price reflects the fact that this old size is a Hawker Hurricane tailwheel and anybody who can afford to operate a Hurricane can probabl...

A question for the IT competent
Over the last few years I've spent considerable time, treasure, blood, sweat and tears working GAVTC into the state I want, both by modification and by rectification. The mods will, in the fullness of time, be available via the LAA but that misses out a massive amount of information - including blin...
