My batteries, 2 off EarthX ETX12A, are mounted on the aft face of the seat bulkhead of my Tipsy Nipper. This is effectively in the cabin and I didn't get a peep from the LAA when I submitted all my documents (I think you may have a copy). I believe there is a reference in one of the LAA tech sheets ...

Visiting by road - camping Friday to Sunday
Nipper unlikely to be ready by rally

Thanks Neil, will do.

The LAA have seen all my paperwork for mods and annual inspection and I now have to arrange a visit from my inspector to get everything signed up. Once the permit to test is issued then I'll be confident to make all my stuff generally available.

I have the same engine and carburettor and, although it is working fine, I had great difficulty in finding anybody who recognised the part (including Zenith!) and no success in sourcing a set of spares. The only response I had was on a call to a specialist who said " I haven't seen one of them ...

Smashing video.
Do you mount the camera using the wing tip fixing that holds the tie-down fitting?

Hi RiP, seasons greetings. The high volts warning on the Leburg units is set to 15.5 volts so that's getting into an area where battery damage is possible, depending on the exact battery type. Some avionics may be stressed, although most modern kit is 12 & 24 volt compatible I've measured the ou...

Could be well worth looking through this very involved discussion:

I find the information helpful and thought provoking.

Just looked it up on the web https://marskeaircraft.com/composite-design-manual $80.00, I don't recall it being that pricey, also there is the postage which was $37.00 in 2021 so you are looking at probably $130 now. However the information it contains is invaluable and very practical and I'm glad I...

Neil, Yes, flight line not attitude. I must have had a senior moment to have forgotten that. Especially as it was a particularly tricky issue competing in glider aerobatics where the flight line defines the entry speed into the next manoeuvre so has to be set up on exit from the previous right throu...

Hi Neil, The flaps I suggested aren't for stall modification but for pitch attitude control during aerobatics to keep the aircraft datum horizontal whether erect or inverted for aerobatic competition scoring. The Gusty and the Acro Advanced both use a beam type of undercarriage. I wonder if it would...

Hi Neil, Well that's a hell of a rabbit hole you've set for me to fall down! I should be doing other stuff but this is much more interesting! To summarise; you would like to investigate a carbon wing to get the benefit of reduced weight and the possibility of incorporating a section better suited to...

Paul, thanks for posting that Gusty article, very interesting. I agree that getting rid of the nosewheel is probably the single most effective weight reduction path for a Nipper. I also believe a tailwheel Nipper wouldn't be any more of a problem than a Taylor monoplane, Turbulent or Jodel, all of w...

Hi Neil, Is it the spar or the whole wing that you can only just lift - which would make it ~ 50lbs? I ask because I am engaged in the same exercise, although with a different aircraft, a Flitzer variant 'K' Goblin. Weight is of course the primary driver. If the spar is 50lbs (which seems a lot) the...

Noticed an advert on gliderpilot.net for this Danish parachute manufacturer
https://www.cahoma.aero/?lang=en
they seem to do tapered packs which move either your shoulders or your bum forward to suit pilot shape and space around the seat.

Jim

Yes, weight is a concern. perhaps the outer tubes could be rolled light gauge aluminium, there's no necessity for them to be stainless the same thickness as the exhaust pipes. If it proves too heavy then the tubes can be stripped off and I'd end up with the RF4 style you have in the photograph. Do y...
