Yes that is how we tested
This here is it at an earlier stage in development however all we did after this was reduce weight, the rear wheel no longer has surgical tubing on it as when they both expanded they rubbed against each other, 2 mini cims now, and we have a Lexan top to prevent ride up of Frisbees. Unfortunately I don't have any recent pics
. We will have a look into the KOP grip material. Unfortunately it is march break for us and we don't have access to our shop so no further testing can be done for a week
. We did play with the compression as well with our adjustable wall
