I have another idea need opinions

what do you all think if a person had a rubber mud flap mounted across the top of each tire to kinda act like a squeegee, so when you are in the water instead of creating turbulence the action of the water coming over the top of the wheel would hit the rubber flap and have a pushing action instead of looping around. I don't know just a thought.

one more thought on this, there may be a worry about mud piling up in there ........so maybe a person could have just a channel mounted above each tire and if you needed to cross serious water the flaps could have a t shape at the top and you just grab them out of the tool box and just slide them in the slots for the water crossing then remove them.

What you are thinking about works. Here are a few videos on the same theme. I built a set from Princess Auto trailer fenders for the shape, worked pretty good.

wow that is amazing how much faster it made it go than if it had no fenders. If a person had the right set up they could improve the performance of most tires in the water.

Absolutely, producing thrust from "non-swimming tires" is an interest of mine. If you are interested in the mini baja approach, search that topic you will find more fabrication details/pics. For quick feedback on thrust producing designs, build yourself a "powered one wheel" setup (variable speed if possible), insert into a large tub/pond to evaluate thrust produced. You will find that the worse "swimming tire" produces the most thrust. The best fender designs are the ones that have a "bar" across the width located "tangential" to the tire diameter. This bar prevents water from going forward, producing "reverse" thrust. When you find the best position for the bar, you then need a "scoop" type deflector to "deflect" the water rearward.

This approach could also be used for "non-swimming" tracks to make them swim.

I was wondering if that idea could also work with a track system now I know thanx for the insight.
