Ever thought of encapsulating the hull?

[FighterCat57]

I'm curious if anyone has considered encapsulating the interior of a hull. I'm considering laying out a decent setup, conformal coating all electronics and connections and then filling the hull with expandable foam.

The only thing left out would be the taps for the lipo's and tube for shaft oiler.

I'm wanting to setup an "indestructible and fool-proof" boat for a family member. But it will have to literally be "plug and play", charge batteries and go. Absolute minimum maintenance if any at all.

For shaft maintenance, I'm thinking a tube/tank filled with vegetable oil or the like that can be refilled easily like a typical shaft oiler...

For speed I'm thinking likely 25-35 mph and run time about 10 - 15 minutes, like a 3s2p setup. Change the prop for higher speeds. Low RPM, like 20k.

For a charger, use a 3s wall-wart style charger. Green light, go, red light wait.

Expected lifetime 100-200 cycles.

Any thoughts this? Anyone attempted to do anything like this?

it sound like a good idea i got a friend that breaks everthing. i spray all the empty spots in my boat for floatation and it make the hull more rigid

Be careful using expandable foam. There is a process to doing it (the right way). There is a lot of info here on the subject do a search and read away.....

i learden from the above mentioned friend he split his fg hull bu completely filling it , i filled mine 1/3 of the way and the excess came out yhe top openinb

I put expanding foam in the nose of a 55" Scarab hull, It was so heavy I ended up digging it all out.

I do not recomend it. (personal experiance)

You might buy a "square seat cushion" life preserver for about $7, They are filled with 1/8" sheets of closed cell foam. You could apply it inside the hull with an adhesive. Kind of like a 1/8" thick layer everywhere inside the hull.

I am pretty certian this is just not possible.

I have been R/C boating for many years and I have never seen one.

Yeah. I liken R/C stuff to the Warner Brothers Singing frog. Works great, until you try to show it to someone.

I'm still going to give is some more thought... perhaps there is a way to simplify things enough...

I have a boat for my kids that is an eco made from balsa and foam. I run a small lehner motor (480 size) on a 427 sub surface prop. Speeds are around 20-25 mph and runs for approximately 10 mins + on a 2S5000mah pack. So yes, it is a feasable project. For water proofing the interior I use small tuperware containers I find at bargain stores for my larger hulls. Or just make a radio box similar to what gas/nitro hulls use. The motor can just be sprayed once in a while with corrosion x and there are a good many speedos that are sealed (I usually just spray coorsion x on a castle hydro and it's good for a season or so.) A mono is a great first time or play boat since it is easy to turn left and right. I wouldn't skimp on the charger though. It will keep your batts running longer if cycled/stored properly. There are too many combinations for me to make any specific recommendations for you but the faster you go the less run time you'll have.
