An easy way to do it is that it should just stay on the nose gear with the canopy off. If you lightly push down on the tail, it should drop.

That's the way mine is set up and it handles well. You might set it up with measurements and double check it this way.

If you are using the 3rd aux tank up between the intakes and you normally land with it full, do this test with the aux tank full.

Good luck with it ... Keith.
