hey everyone, I'm trying to fab up a new pushrod for my navik. I dont have one to work from, so can anyone tell me how long it is supposed to be from ball link to ball link, and if anyone knows the size of the balls, looks to be about 7mm, that would be good to know too. Some of the online hobbystores have 6mm and 7mm ball links for r/c helicopters. Has anyone done this and what did you make them out of? Thanks so much.

I think I have my Navik at home somewhere. Can you be a bit more
specific and I will try to measure the stuff for you. Trevor (V2915)

Sure thing. I am missing the pushrod, that runs down the vertical tube, between the actual windblade, and the lever at the bottom. there is a ball link on each end, not sure how big. I just need to know how long that pushrod is, so that i can make one up. I think its made of fiberglass with two small ball quick connects on the end. Thanks again
The overall length of the rod, the extreme measurement , is 38 3/8 inches. From base of socket to base of other socket is 37 ½ inches. The upper socket is fixed to the shaft but the lower appears to screw onto a bit of threaded rod that protrudes from the end of the shaft. A nut on the threaded rod locks the socket in place. This may be to allow some minor adjustment. The ball is between 6 and 7 mm, perhaps it is 7 worn down. I assume you have the ball ends but are missing the sockets. The shaft is fiberglass but, it seems to me that a length of small diameter Allthread could be used, perhaps wrapping it in fiberglass tape. The OD of the shaft is 10 mm but I don\'t think that is a critical dimension.
I had taken pictures of the ends and tried to upload them but was not successful, or perhaps I was but don\'t know where they went. If the description is not clear I will try to upload again.

Just a thought to add to Craig's thorough description:
I suspect the weight of the rod might be critical to the balance of the whole rig. It takes a very small amount of force to change the water paddle direction. The wind paddle should stand vertical when released, using the lead counter weight to ahieve this. A heavier piece of Allthread might weigh the whole works down.
There's a selection of fiberglass rods available, both hollow and solid, at plastics shops and kite building suppliers such as
I don't know if the Navik rod is hollow ... my guess is that it would be.
Good luck with your project!

Karl, turns out my Navik has either gone for a walk or is in my boat locker - I hope Craig\'s info is helpful. I am going up to the boat on the 20th of Feb. Trev (V2915)

I added 4 photos in an album called "Navik Windvane" on the Yahoo site. This link may work, if you're logged into Yahoo:

I measured my rod from center-to-center of the socket holes and came up with 955mm, or about 37 9/16", just about the same as Craig's.
I believe the socket that's adjustable should go at the top, as it's easier to access there.
The sockets themselves are identical to the socket on the plastic linkage that gets connected when the paddle is installed. If you had a couple of those you'd be half way there!
