I make these flared tubes at just over material cost plus shipping and packaging.

I have a couple of the rings available.

Louver set for Rabbit radiator installation protects the radiator & provides negative draft to increase cooling efficiency.

Just ask and I'll email you the drawing, no charge, and you can build them yourself.


Inspection panels with spider & disk, optional safety clip at edge for fwd of wing spars. Set of 6 for 601 series or as required. A drawing has been provided so you can build these yourself. Click on the drawing for a printable size.

Nylon bearing set, for 601 & 701 tri-gear struts. These are now part of Zenith inventory and so I have discontinued making these. They are a good way to reduce wear of the landing gear and not too hard to make.
