@aidyj88 You can participate in as many races as you want. If you just want to/only have time to make one or two races that's totally fine. You'll still be awarded points based on where you finish since those go into (potentially) making the final heat.
Easiest way to race with other people is to join the official UHL server 'www.uhlhydroplanes.com'. I believe there is a way to set up your own server but it's a hassle and above my skill level.
You can create custom paint schemes with pretty much any image editing software like Photoshop, you just need to save/convert it to a .dds file for it to show up in game. A scheme also has to be downloaded by other people for them to see it in their game. The blank templates are here in CP's dropbox: https://www.dropbox.com/sh/r44qc2jvr4bepns/AAARhfDiTB-HxW28Dma0QWbYa?dl=0
I'm interested! Never been before but first time for everything. Quinton is interested as well.
