Dang rudders on 2960s are small.

As Pete says, 2960s are very long floats. I seem to recall noting at one point that they are longer than 4580 and maybe even 4930 Beaver floats. They are great floats in lots of ways.

2960 vs 4930.jpg

From the 1975 Edo brochure: 2960's = 20 ft 10 in; 4930's = 22 ft 3 in. I just pumped two sets of 4930's and the 2960's on my 185 this morning after a couple days of rain. 4930's are longer but the 2960's (at least my version) have 8 pumpouts per side vice the 6 on the 4930's.

And I just looked and my attach points are both incorrect... :roll:

Makes sense, all I've ever had are a single rudder. Yes I have rudder envy :roll:

Someone in Alaska offers a rudder enlargement option. I have one on my 1320's and had two on a previous model. Not sure of the source of parts. With two it becomes almost dangerous to turn them in a crosswind. They want to sink the outside float unless careful.

I'm already pushing it with the one I have. Already have climbed the wing strut to bring the opposite tip back up :oops:

Yeap, here is my old PA-11-90 with the one over-sized rudder in some snappy winds.
I did this two or three times while my oldest son was supposed to be taking photos for my old training manual back around 2003.
I finally looked over and there he was talking to somebody and not paying one bit of attention.

Good example Alex. Al Wright told me the same when I had my PA-11 on 1320's. Watch crosswinds especially with the bows up and when turning into the wind. He suggested turning to the right so if the left float goes down the pilot can scramble to the right strut like Glen mentioned.

I was trying to show a comparison between the EDO style water rudders and the PK style water rudders. Of course you can never find the photo you are thinking about....

Good grief, Alex! Wind? Look at the tiny little waves on that pond. No wind there, just a freshening breeze........

The PREVIOUS photo of the 800 pound PA-11 was shot when the wind was only 15-18 knots. That plane was a pure delight to fly.
She would leave the water at 38 miles per hour. (34 knots) and climb at 45-50 mph (43 knots)

With a C-185 you can start your slide at one end of Beluga lake and be at about 500- 600 feet at the other end while climbing out.
In The Dragon-Lady you would be at 800-900 feet if you played your cards right.

I was referring to the wind in the previous photo. The glassy water pic might have been on Rocky Lake. Not sure... I just like to add pics when making a response...

The previous owner had the cables connected to the wrong holes on the rudder tiller. . ( I hate it when that happens) Skywagon Pete guessed that and photos proved it. So I changed to the correct location per EDO drawings and obtained more rudder deflection. The 20 knots winds have died and now it is raining buckets... So I have not seen how much it helps while underway just yet. ODDLY ENOUGH... All the other EDO 2960s in town are rigged incorrectly.
Reviving this old thread as I have had issues with steering with my 2960's. Noticed during turns to the right that the right water rudder was partially coming up out of the water. Pulled my water rudder springs and found them deformed.dc387de14b12463f96917880.jpgSo ordered a new pair from Kenmore and they came looking like a normal spring. Installed them and they helped significantly with the steering and keeping the water rudders down. I did verify previously based on this thread that the cables are in the correct holes. So here are my two questions:1) I look at the picture of Alex's water rudders and his look to have the same deformation as the ones I took off. Does that come from the design of having the spring come up through a hole in the steering arm which bends the spring at an angle when the water rudders are up?2) The floats in Alex's pictures shows two springs per water rudder, one on each side of the post. This doesn't appear to be standard from what I can see in the 2960 parts list and diagrams. Anybody else use two springs on 2960's?Thanks!
