My name is Eddie
I have had a Kiwi kit for over 18 years started to build it to fine that i lost the plans.
I email Sig this is what thay had to say.
Hi Ed,

The Kiwi has been discontinued and gone for a few years now. We no longer have the plans left.
You might find them on-line at Ebay or on the R/C chat forums.

Regards,

Sig dose offer a Constrution Manual for the Kiwi.
Do you know where I can get a set of plans?

Yours Truly Eddie
