I just did this and it worked out great! I'm sure I am not the first to do this but I Just thought I'd pass it along.

1. oil up the pushrod with a light oil (i used after run oil) to stop the shoe goo from adhering to the pushrod. a thicker oil may work even better...
2. put a glob of silicone rubber (Shoe Goo) on the end of the tube, so it is on the pushrod and on the tube covering the opening.
3. let it dry completely!
4. Move the pushrod to free it from the Shoe Goo, and re-oil the pushrod. (carefully as not to place too much stress on parts)
5. You can then put vaseline on the end of the goo on the pushrod to further seal the tiny gap.

Hope this helps!

I'd be concerned with the pushrod tightening over time (Dirt and grime etc)

I just put a big blob of vasaline in the hole.

I havent had any problems yet...
all this does really is make the hole smaller, so you dont need a huge glob of vaseline...
If there are problems, it is not hard to remove.

Dan,

You'll have to bring that thing up to Willmar sometime now that the lakes are liquid again!

That would be fun, I think I just may... I am on the final steps of mounting up the floats and then I still need to make the rudder. Still trying to decide on whether or not to use the ventral fin. As of now I don't think I will unless on the first few flights I think it needs it. I made panel lines and rivets (with a pen) and sprayed the floats with Flat clearcoat Lustrekote to get a simulated aluminum float finish. (my dad's idea... He used to be a painter at Whipline floats)... yeah, When are you guys haveing a Float Fly? just PM me with any info...

I am assuming this refers to NyRod-type pushrods.
I am a proponent of nyrods, particularly for float-flying.
They are inherently pretty tight. The water has to go a long way before any gets inside the airplane. Even with the throttle pushrod.
Before I worry about anything to get them any tighter, I'm going to assign priority to other places where water will get in first:
1. the holes where the fuel lines penetrate the firewall
2. the wing saddle
3. Window openings (if applicable) or other cockpit openings.
4. Switch opening (or switch pushrod)

If you dunk it, all these places are going to be leaking/pouring in water while the plane floats nose down with the pushrod tubes two feet in the air. This is assuming it's a minor dunking with no damage. If the fuselage is damaged, all bets are off.

The tip about silicone sealer is one I will file away for whenever I build a radio-controlled submarine.
