Tailwheel a *****cat on grass but a wild animal on pavement

[jiott]

Here's a easy way to check main gear alignment; Make sure the main tires are inflated the same and then attach a 8 or 10 ft piece of pipe.....

I would strongly suggest you don't lay the pipe across the face of the tires. Use spacer blocks and lay it against the wheel face. Iv'e seen tires with very uneven sidewalls; it could give a very false reading. You are really trying to evaluate the rolling axis of the axles.
