I maidened my Super Cub on floats yesterday. Two flights without any major incidents. My cub has a no name brushless motor a 30A ESC and runs on a 3S 2000mAh Lipo which is good for 20 minutes flying. The only problem I see is the lack of a water rudder. When trying to taxi to shore it is very difficult as the torque of the motor always want to turn the model and there is no way to correct it.

Anybody got any ideas for installing a water rudder?

Easiest way: Hang a piece of pushrod wire down from your rudder to the water's surface. Solder a small piece of tin can stock to it.

the stated size: 1 1/4 to 2" would be about right for a 60-size plane. for a 400-size electric, maybe 1/2" square. Even then, it should only be about half in the water when you are sitting still. Once you are moving you'll pop up on the step and the WR should not be in the water then...just adds drag.

I've been wanting to get a float set for my cub. often wondeed how to steer it on water. That is a great idea to make it and cheap everything around the house to do it.
Thanks Jim.

It's looking like I'll be spending a couple weeks on a lake in Utah this summer, and that's clearly much too long to go without flying. I need something on floats that's pretty much bullet-proof since I'll be away from my tools the whole time and I've never done any float flying before. Is a Super Cub a good choice?

A little out of my league there NASCAR, I haven't worked my way up to the five-cell arena yet. A little on the hefty side too; I still got to fit it in my car with everything else. Looks like it flies awesome though.

Float mount:
Servos are reasonably waterproof, especially if you keep them above the waterline on the floats. They can also be sealed into a pocket, and fitted with a rubber ring under the servo horn, just snug enough to seal out water but not to bind the servo.

The servo in the float looks like a good idea
I've been flying mine without rudders, just fatten it up and lots of rudder

Well, you don't HAVE to have water rudders.
I have not offered this rant in a year or so, possibly that will reduce the number of vegetables hurled in my direction.

(1) If your motor is running, you can steer without a water rudder. If it is NOT running...it doesn't matter whether you have a water rudder or not. Since everybody in THIS forum is flying electrics, that point should be moot.

(2) Blipping the throttle to get a blast of air over the rudder doesn't help. You just draw attention to yourself as you drift into the God-forsaken snake-infested swampy briar-patch on the inaccessible shore of the pond.

Awesome! I didn't know about that, and I needed it - thanks!

Would a E-flite Park 450 do alright with a SC-LP & floats?

I have about 200 old RCM mags. I hate they went out of business
