SuberAvid added a post in a topic Phat Tires
I haven't pulled the wheeles off to inspect them closely but just looking at the camber on the tires, the seem to be doing good so far. I landed a new place on the Kashwitna last week and it is hard to see this strip because it is in the trees and crossways to the river. When you are low enough to land it you can't see it coming. So I was approaching it low, in a slight turn and as slow as possible and lost lift a little high and did a pretty good bounce so I tested them pretty good. I think the tires at 5 psi may help, even though they are wider and the outer bearing has more leverage on the axle. We will just have to keep an eye on them.
I took a few pics while I was there and flying back home. Had a beautiful sunset but couldn't get my camera to not flash when trying to get the alpenglow on the mountains so ther is a lot of reflection off the lexan in that pic.

IFMT added a post in a topic tailwheel spring rear support
Here is my second picture upload attempt. One thing about the beefier spring is your aoa on the ground will be reduced slightly. If you are running bigger tires on the front it doesn't matter. Also, I have a sube hanging on the front, with extra weight at the back so a beefier spring is needed to take that extra weight. I think a heavier spring that is actually a spring is the way to go. The one I bought from Brett could be easily bent and the tailwheel broke off right at the mount kicking the **** out of my rudder as the springs to the horns dragged it along.

What to do when it quits
There are two mistakes a pilot often makes after an engine quits. First it quit for a good reason. Don't try and restart it. You'll likely destroy the evidence that made it quit. Second don't automatically blame the engine for your troubles. The majority of Rotax engine stoppages are due to a fuel starvation issue.
This article is another great troubleshooting source.

Understanding the Mid-Range circuit VERY IMPORTANT ARTICLE!
One of the easiest way to burn up a piston is by not understanding how the Mid-Range circuit of a two-stroke works. Please take the time to read this article and understand what it is saying and how to apply it the operation of your engine. In a nutshell: Don't pull the power back to 4000-5000 rpm and unload the engine by starting a slow descent like you would with a traditional engine. Your EGT's will quickly exceed the redline of 1200 degrees.
