Before you critisize the use of fans you should look into their usefullness.

The fans that we will be using (in 1729) are two 16" 8 pitch props that will give us 4.8 LBs of thrust each ... thats a total of 9.6LBs of additional thrust. I believe S.P.A.M.s propeller gives them a bitmore than 10 LBs of additional thrust.

If you consider that your robot will typically have between 9 and 15 LBs of thrust from the wheels (depending on whos' numbers you believe) this is a significant increase and can be a great advantage if the drivers can utilize that extra thrust.

Let me know what you think of the propellers after the regionals. Personally, I believe that there will be a propeller assisted robot on Einstien this year.
