Honestly, people thought that the earth was flat and that only birds could fly. Anyone want to place bets?

Don't lie, you were just taking a shortcut. Lazy math does not make good triangular wheels!
Ok. Tire selection not withstanding, certainly you have a chance at being correct if you are measuring the RMP cumulatively for the dual motor approach. 30 RPM individaully would cause an excess when processed through both axes simultaneously as your 3D image suggests you might. In that case, condensation is going to become a matter requiring still further exploration and a likely thermal solution to the problem you're having with the Rock Force's performance.
I trust you're planning to filter the results of your math through a binary version of Berwalt's Opposing Rotational Mass Formula before you begin initial testing.....??? Safety first.....
There is no way I would want to get into all that kind of complicated stuff.
He'd probably be the dead ass last person to reply here.
I have assumed a balanced wheel which will void most rotational mass formula results but if a variance of 5% is assumed to account for variations in foam, beadlock screws, tread differentiation, etc then the follow analysis is what the results yield. Even then 5% is high and the results are well within anything that is suggest by OSHA in similar circumstances.

I'm suspicious now. Looks like the only way you got the numbers to work is to use the brown foams. As you know, there's so much variance in the manufacture of those that your "numbers" are rendered worthless.
I did cook up a batch of brown foam big enough to do all four tires last night, though. That should eliminate batch variations and help to validate your test results. Damn thing's as long as your arm. PM me if you want.

I think I get it now.
seriously, I've thought about making some "square" shaped foams to help grab more on climbs.

I can see it working, really has a small window to fail, it would all depend on tire's and foam. But the concept is there could be a killer climber and down hiller also.
Can go 2 way's like said could be the biggest thing to hit RC Crawling or the worse idea ever in this hobbie, eaither which way Harley will 4 sure engrave his name in the history books of Crawling.
Way to go brother wish you the best and can't wait to see the first prototypes.

So let me get this right so I understand as I it as I think I do. If I am wrong then the boat left along time ago without me and Im sorry for being ignorant. I think I understand the theory. By the way (all the mathmatical talk is only confussing the basic guys! even me since I am a land surveyor by trade.) So this is what I am figuring it to be if I am correct. Basically the wheel has a triangled beadlocked rim and the tire would have to be specially designed to seat on the beadlock. But the outside of the wheel in all essence is still rounded. So when you are moving along rocks or bumpy ground, the flat parts allows you to be stable while the edges give you the advantage of sticking to a specific area either up or down with lower chances of movement? The wheels are still round on the outside but because the foam inside allows for seating to whatever your running the wheels on. It has the capability to grip on more substances and even more so because of the knobs on the tire surface? is this what I am understanding?
To add, because this would be on 4 wheels, and the speed that these go, the chances of all four wheels making seat at the exact same point is vitually slim to none. even so, the tires round surface would overcome the torque needed to move in forward or backward motion. Still higher torque, but not enough to cause extreme or higher than needed force.

They are MOA as well. The motor is mounted right to the case.
RF axles are 30:1 in the case.

You're overthinking it. Try and understand the math first :lol::lol::lol:

Well Josh, I got the proto set all programmed up. "thumbsup" Waiting on after hour machine time now.
You know my address "thumbsup"
We can unveil them in Donner, we will have to keep the photos to a minimum until then though.

pretty innovative idea Harley. If they work good I am sure they will have a hard time keeping them in stock"thumbsup". But every time I look at this, it reminds me of my Musubi lunch:lol:
