Floating Crash Recovery

[Papa]

This is a challenge for Ed!

Looking at Tom's u-tubes I see something that might work for us.

One is a barge with two reversible props and independent throttling for steering.
the second is the fishing reel system.

Combining the two would work well in the weedy FB.

How would this work and would brushed motors be a better choice?

I remember a set of plans in a RCM Modeller mag about 20 years ago for an RC float plane retrieval system.  It was essentially an RC catamaran boat in the shape of an "H" (when looking from the top) and it had two sets of props and rudders one in each hull.   It just went up to a stalled float plane and caught one of the pontoons between the "H" structure and drove it to shore.  The centre of the "H" (the connection between the two pontoons) was raised so it would ride over the tip or the back of the float of the stalled plane.  The write-up said it worked well.

If you want I can cobble one together over the winter.

For what it is worth.

The difference between glow float planes and electric float planes is the type of recovery that's usually needed.

I assume the majority of glow float plane recoveries result from a quite engine, either at taxi out, during flight, or during landing.  In this case, the plane will usually be upright and close to shore and will just need a push back.

With electrics, we very rarely see this scenario.  Instead, when an electric plane needs recovery, its usually because it's upside down in the water (or stuck in the weeds).  Also, we fly a lot more smaller float planes, which are more likely to be blown over while taxiing, or even landing. 

So I don't think it's a simple matter of pushing the planes back.  We need to get them out of the water ASAP :-)

The barge with the scoop affair might be the way to go EH!

This is a huge task.  The amount of airframe that could be under the water is at times a lot I imagine.  The weight of a airplane filling with water could be LOTS.  The drag associated with being stuck in weeds could be quite a lot of force required to extract.

This is my best attempt at a solution!

 Piker,

So why do you land them upside down!

I assume this idea to reduce the amount of drag...

How about one of these options:

So far I think the woman on the catamaran powered by a bicycle is the most "attractive". Only troubles I see with the set up is that must be some thick water to get traction on it like that!

...I could have guessed
No thick water required, torque is transferred from the rear wheel to under the front wheel.
