Re: GATVC; seat & harness, wheels & brakes, & instrument panel

Neil, Thanks for the comment, it reminds me of a conundrum I haven't been able to solve. The discs I've used are unmarked but, if you look at any which are marked with the direction of rotation, they appear to put the spokes in compression which is very counter intuative. I would love to know why th...

Re: GATVC; seat & harness, wheels & brakes, & instrument panel

Well that was only partialy successful. I'm not sure why the reduced photo was still so large and drove the width of the post. Also some text and a picture was lost. missing text; To finish the seat back; trim the unfinished upstand edges drill the hole for the attachment bolts (same as original) cu...

Re: GATVC; seat & harness, wheels & brakes, & instrument panel

It's been over a year since I started this thread so a progress report is long overdue. Gider maintenance at Windrushers and life in general have thrown considerable delay into plan A but the end game is in sight. I'll put all my information in a file for anybody that would like it when the mods get...

Re: Nipper landing on a (french) car

Wonderful!

Note the expression on the young lady's face. It is exactly the same as I've seen from my wife many times and it translates exactly from any language as "You stupid man!"

Which is precisely what she said on watching the video.

Re: Undersized bolts?

Rob, I think we are in the business here of making things work in an acceptable manner, rather than trying to guess what somebody did many years ago! It certainly makes my head ache trying to imagine how your mechanism got assembled like that. I've been amused by the variety of bolts I've found used...

Re: GATVC; seat & harness, wheels & brakes, & instrument panel

Neil, thanks for the instructions on posting pictures - I hope to have something worth viewing soon! I am working as fast as I can on the LAA mod papers but they are not on the critical path as the aircraft can be flown for it's permit renewal unmodified. By far the most critical part is the wheelbr...

Re: Undersized bolts?

I stand corrected here. As Stuart has said the plans call for an A59 series close tolerance bolt rather than the A25 standard tolerance I had assumed. Unless the drawings call for a reamed hole it seems inconsistent to call up a precision bolt for a drilled hole assembly. But maybe I'm trying to sec...

Re: GATVC; seat & harness, wheels & brakes, & instrument panel

Progress report First a rather embarrassing error – I typo’d the registration of my aircraft in the thread title. It should read GAVTC, as it does in large red letters on the side of the aircraft! The seat back and shoulder harness mods were discussed with Francis at the LAA test pilot lecture and v...

Re: Undersized bolts?

Hi Rob, While early Nippers may have been metric I think that 4.5mm is very unlikely as it is not a preferred size. Also, on small, simple light aircraft, undersize or precision fit hardware is most unlikely, just too expensive or difficult to source. I guess this thread follows on from your previou...

GATVC; seat & harness, wheels & brakes, & instrument panel

I have, at last, enough time to sort out the permit renewal on GATVC and I thought I'd tap into the font of knowledge that is the Nipper Forum. There are a few issues I've been pondering and would appreciate comment from those that have experience and ideas, GATVC is a Slingsby Mk111 with no mods. S...

Re: Rudder pedal to nose wheel cable Nipper 36

I'm not sure about Neil's reply. My Nipper is, as far as I can tell, 'standard' and the geometry of the pedal pivot, rudder cable attachment and non adjustable stop does not allow you to reposition the pedal by adjusting the cable length. The gross cable length is set by this geometry with fine adju...

Re: Brake discs

I'd like a peek at the 'Halfords' solution as I think that within a couple of years I may have to go down the Tost hub /400x4 tyre route.

Re: New old Nipper

Can I double check that the belly panel bolts are 4BA? Just making sure that I'm getting the correct ones for the new set! #6 UNF is very close, close enough for it to be difficult to check if the nuts are a little worn. BA sizes are a little difficult to source and I may replace all the nut plates ...

MK3 drawings wanted

Does anybody have a set,or part set of drawings that they are willing to part with? ( I'm aware there is some problem with the fuselage drawings)
My aim is to build a set for my aircraft documentation pack. [GAVTC]
