A number of questions immediately spring to mind:

1) what does "60% speed" mean? 60% of the motor's rated free speed (in which case how did you measure the speed)? 60% command to your motor controller? 7.2 volts from a DC power supply? or something else?

2) what motor were you using, and what gear ratio?

3) you said "wheel" and not "wheels". Is this a single-wheel linear shooter? or a curved chute shooter?

4) were you using the same model and size pneumatic tire as R3D? or something else?

5) how do you know the speed of the R3D shooter? I couldn't find that info anywhere. could you post a link please.


edit:
I just now saw your video. Whole lotta slippin' going on as the bee exits. Have you tried slowing down the wheel?
