Re: New engine

Sven. You are welcome. Have a look through the tech gen, particularly the early Pitts articles. You will find a lot of similarities to the system used for the Acro. Aircraft Spruce used to carry useful generic parts that could be of use or adapted. As for the flop tube, it was a piece of fairly rigi...

Re: New engine

Sven, greeting. Well done with getting your Nipper back flying. Four area to concern yourself with if you want to think about when turning your existing VW into one with an inverted fuel and oil system: • Fuel system - engine • Oil system - engine • Fuel supply - airframe • Weight. You may not think...

Re: Nipper firewall

Jim Bending metal is not too difficult when it’s a straight bend, but bends on a radius you really need have access to a press and facilities to heat the material. However, for a cold bend, you should use the correct bend allowance for the material - preferably more than the minimum. To lose the exc...

Re: Nipper firewall

Hi Jim, I don’t have a drawing but in the past I have one. Ex RAF tin-basher so it was no biggie for me. Use gripper pins or bolts to secure the old firewall to your new material by drilling the 2BA size holes through the bracket points. Then mark around the firewall perimeter using a pencil (use of...

Re: Zentih carburettor - service or replace?

Jim, I would say the CD150 is well proven on the Nipper. Owners with 1835 VW tend to go for larger diameter induction pipes. I would imagine that may not be possible with the 1600cc unit? But what size jets to use?

Re: Zentih carburettor - service or replace?

Back in Alan Ayles’ day NK&C used to keep overhaul kits in stock. Don’t know if the new lot are worth a try.

Re: Engine removal

Malcolm. If that is the case, then not difficult to remove. The ACRO engine installation requires that the standard Nipper fuel filler cap and fuel contents float are both removed, and that the redundant tube that guided the float level wire is blocked off. The various new plumbing items on the modi...

Re: Engine removal

MGR. OK, a my 3 with a flop tube. Is the fuel tank modified as in the images below? If so, removal is easier than you might imagine. Slingsby did publish a mk 3 owners handbook, but I no longer have a copy. There is also a parts manual produced and supplied with kits. I think my copy was also publis...

Re: Engine removal

MGR. Hi, is it a mk 3, or is it a mk 2 with the attachment backplate? The top attachment is usually by studs that screws into the engine backplate, or in the case of the original mk 2 was rod end assembly. Between the engine and firewall there are usually 4 light alloy spacers. These sit ‘loose’ on ...

Re: Leburg

MGR - Hi. To remove the firewall requires the engine to be removed first. Photo is of the firewall for a Mk 2 Nipper - modified by a previous owner to accommodate a dual Bendix series 2000 magneto.

Re: Spar clamp material?

Surely this is just the sort of question that can be answered by Aeroweld? They should hold details of the current drawing for this part, as well as the history of any amendments to the design.

Mk 3 Nipper available.

I know of a Slingsby built Nipper Mk 3 that the owner wishes to sell. It’s dismantled and apart from having the turnbuckle x-brace mod. complete, it is in original condition. It has not flown or the engine been run in 30+ years. This aircraft will require a complete restoration and a new engine, so ...
