Hi Rob, In addition and just in case you are wondering... "if excessive looseness is found in the hinge pins of ailerons, elevator or rudder, these pivot pins (ref. SP/4Z/B14-0 3/16" ) must be replaced by pivot pins of the same specification but of a larger diameter, which should not excee...

Hello Rob, I don’t like to be outspoken on the web but if you can feel this much ‘play’ in the control circuit then in my view this is seriously wrong and should be remedied straight away. I have experienced aileron flutter in a Nipper (caused by slack aileron cables) and it is not an experience to ...

Is there any significant difference between Mk1, Mk2, and Mk3 variants? Yes - The engine mounting on the MK II Nipper will not accept the VW engine directly mounted. On the MK II Nippers there is a transition casting between the airframe and engine on which the earlier, lighter engines were mounted....

Hi Tom,

Another photo - do you have any witness marks from the top forward fitting to help you?

Ref your search for VW 1834cc cylinder heads.

I have two ex-Nipper VW 1834cc single port heads which I would like to exchange for VW 1600cc single port heads for a Rollason Ardem engine which I am rebuilding.

Jim,

My Nipper has the standard pedals so I can give you the dimensions and a sketch. You have my contact details so give me a call. I found it quite simple to have mine returned to standard. I used Airweld (near Winchester) for the welding.

Gary,

Confirm R/H thread. Rollason used 0.002" interference fit on their engines. The prop hub was heated in an oven before being offered up.
