What

[inventing_man]

Our visions are one in the same, The WHAT is just smaller scale , and able to self propell as one unit ( with ATV or Motorcycle inplace) on land . Not fast, but functional enough to drive itself out of the water and on a land based trailer. It can also be loaded the typical trailer in the water boat pull on way .
I'm looking for an diecent performing 1/10 th scale RC 4 wheeler in which to scale a 1/10th WHAT from .

Radio Shack. Whenever I go into Radio Shack they always have something weird like that.

Just me lurking around again.... Not to put anyone down, cos I really like the idea, as a fun project. But "what if" (genetic flaw, sorry); you at "full throttle" get a rope in the proppeller? are you then suddenly, airborne on an ATV, with rather limited operational capabilities in water (which then will occur in 0,8 sec's).

Oh I see, you have mentioned straps... So this can only occur if straps are not properly set/ skipped. Real cool way of landing though, unstrap just before you hit the shore, and zoom off. (What about a military version, catamaran, high speed version for landing?)

Cool idea

Hey inventing man. I think the self launching, self propelling ideas has potential.
The closest production boat I can think of, to your concept is at
www.sealegs.com

I have been keeping an eye on amphibious boats over the years, but I still havnt found my ideal. My preference is for a real seagoing boat, with sails, that is self launching and self retrieving. Imagine getting to some great secluded place and being able to park on the beach out of the waves.

I think your idea has this potential in a bit more limited way. keep up the good work

Hey Thanks ! Interesting idea about speed launching .
I plan to use jet pumps instead of props just for safety . . But who knows what is lurking just below the surface . I'm sure a hazard for every form of boat AND drive exist down there . I've spent a few hours trying to get a trot line with metal leaders out of my prop before
You wont be able to skip strapping down because that is what keeps the ATV drive tires FULLY planted and in place to the dyno drive chamber. Or the motorcycle standing upright and in contact.

Thanks for the link! Haven't seen that before. One small problem with it

Why only 10 minutes or 1km on land?
Because the Honda inboard engine and hydraulic transmission oil are air cooled, after 10 minutes of constant use it requires approximately 20 minutes to cool down before use again.

My drive line should let you crawl around as long as you want to go .

You know, I have never seen that little "gotcha" before. It is a bit of a downer.

Mind you, with a standard non-marinised land machine, you would get a lot of rust and perhaps water in bad places too.

We need to solve a few problems yet, i guess

[inventing_man]

Yeah , water = extra maintenance no matter ....WHAT ..... (its kind of a universal word I guess ) Good seals , good grease and a design that allows easy service is about the only defense . I'm in a fresh water habitat here, Not too familiar with the Salt world other than it hosts very large , very hungry critters.
I'm looking at buying a (real) High performance 1/10th scale RC monster truck for the ATV platform. The "toy" versions are not very scale speed like or in handling. I can sneak a 4-6 channel airplane radio in it and be able to RC some other functions as well. Once I get the scale nailed down, I'll carve the entire WHAT out of foam install bulkheads and epoxy glass it
If the foam and glass works out, I may adapt it over to the full size prototype instead of using pontoons and frame structure. It will be more hydro plane -ish type hull than pontoon-ish
