Does it also have to be inflated all the way to 36 psi? Like, will any less than essentially maximally full cause unbalance?

I saw the Lunch with Andy episode and will do that though; does it have that significant of an effect?

How accurate does it shoot at close range?

What speed are you running the pneumatic wheels at?

I agree with your suggestions about the lack of support causing vibrations.

This video gives some suggestions about balancing pneumatic wheels:

The wall is about 50 ft from the shooter, and the frisbees hit above 20 ft in the air (the lamps are hanging at about 21 ft).

We never tested close range; this was a test on friday night and we haven't been back since.

We're running them 1:1 on CIMs.
