This new forum topic has been created to allow IPLA (International Potato Launching Association) members to communicate quickly. A special Thank You goes out to our host Joel Suprise for allowing us to conduct this discussion here. Thanks Joel : )

To join the IPLA, please vist http://ipla.quibble.com to sign up. It's free to join and only takes a minute. Non IPLA members are welcome to post in this area as well but membership to the IPLA is encouraged. The IPLA will migrate to an interactive site where you will be able to upload your own profiles. For now, please email your submissions and allow time to be added to the list.

It is hoped that informal online competitions can be held and the results posted here at spudtech. The types of competition as well as the rules and classifications that govern them will be determined in this forum. Honesty is a key factor in making online competitions work.

Here's some initial thoughts on the subject. Launcher classes for pneumatic and combustion could to be created. For combustion, the classes might be based on chamber volume like; subXXXXcc, XXXX-XXXXcc and unlimited, where XXXX represents chamber volume. Pneumatic experts would need to come up with their own set of classifications.

Ammunition for competition should be widely available and could be subject to it's own regulations concerning size and type. Russet potatos might be a good choice.
Because of the often estimated measurements given for longest shot recorded, it might be better to instead concentrate on accuracy for initial competitions. The currently proposed target for accuracy is a 1 foot square piece of plywood placed a fixed distance from the ground and shot at from a specific distance. The number of hits during a set number of shots would then be reported here as the contest result.

Above are some suggestions for competition but what's important is to have a format that everyone is happy with. Please post your ideas here for others to read. Hopefully some standards can be established quickly which will allow for the first (AFAIK), interactive, worldwide spudgun competition.

awesome, I'm stoked, hopefully this will help the ipla start the ball rolling, for distance, accuracy would be way off, always remember hang time, gravity is basically the same everywhere on earth! Sounds great!

that all pressure chambers be hydrostaticly tested and certified
to at least twice the required competition set psi,ensuring safe launcher
construction procedures.
a failure during competition could have catastrophic consequences

re veg.

thought has occured to me. that we'll need 2 or more catagories. one for handheld guns and, one for 'carriage' mounted guns. prolly shouldn't allow bench mounted guns ala Latke's c : b tests

probably should be more categorized by valve types than size. The amount of air has very little to do with the performance. The difference is if you are actuating it by a ball valve, or something like a piston!
