Absolutely... Gotta bust out the McGiver skills and make it happen. I knocked the bearings out and I had a set of hubs from an old Associated RC car that just pressed into the wheels. I still had to do as you are and put a rubber tubing bushing on the carbon shaft to make fit into the hubs.
E: Fastest time to advance 3 feet.
But what I would really like to see are full scale human driven models with variable pitch props in an all out baloon chase. Give the baloon a 3 minute headstart on a dry lakebed and the first person to catch and pass the baloon gets all the money women and...
Ha Ha! You may have the parts but you haven't mastered the VooDoo spells.:smile:
This is fun stuff JB! Let me know if there is ANYTHING you need in the way of parts and I will shoot them out to you.

Thanks Jeff! and sorry for being late to the post here. And thanks for the "fmt=18" tidbit on the youtube to get hi-res video.

schroder,
Please watch that video again and pay close attention to how I VERY CAREFULLY do nothing more...
Not at all. You read my last post. You know where I stand on iceboats etc. I dropped in, restated the problem from a different angle so I could reduce it to the simplest of questions, then I started asking those very simple questions. Questions that if were met with simple answers would have...
And my answer is that I don't know for sure. Here is where I'm at:
1. The iceboaters of the planet certainly claim that a VMG downwind is a piece of cake. There's lots of them and only one of me so I'm inclined to follow along.
2. It would seem that you could take all the principles of...
Jeff,
This could only be true if the device is moving. Think of it like this: When you are running on the treadmill at 10mph in a room with still air does the air pressure on your back assist you IN ANY WAY at maintaining your forward speed? Before you answer, remember that the air...
Yes and yes. But we are not standing still on the treadmill. We are running at 10mph. Just like the cart.
So, if it experiences 0 wind speed and 10mph belt speed then what is it that is powering the propeller. Since ThinAirDesigns hasn't answered, I pose the question to you Jeff.
So now I take it that we are arguing that Jack Goodman's definition of "still air" means that he actually had a room with 10mph air blowing across his treadmill.
Is this what you are now claiming? Please explain. If I am standing stationary next to the treadmill and the cart is on the...
Ok, call me dumb but directly from the link I posted:
For those who missed that July issue, No. 21, a vehicle on a treadmill in still air, with the wheels going eight miles per hour is the same as a vehicle going eight miles per hour down wind, in an eight mph following wind. If a car moves...
Excellent... So let's stop right there and there on that point and work it out.
I'm saying that I am an observer in the same inertial frame as the cart on the treadmill in the hallway at the break-even point. I cannot feel any wind. Therefore the cart does not feel any wind.
So if the...
In order to understand this you need not understand sailing, relative wind, apparent wind or ANYTHING other than Newtons 1st law.
To get your head around this, imagine the cart facing west sitting on a long treadmill in a long windless hallway. Start the treadmill which runs towards the east...
