Does anyone know of a good method for correcting tracking problems for the lower blades on a CX2? I've had problems even when the blades are perfectly balanced. Thanks for your help.

Boiling the blades can help. If not, then replace them with a set that are better matched for both weight and pitch.

Thanks for the info. I can check weight but how do you match pitch? Also, what does boiling the blades do?

Boiling the blades helps to take stress & warp out of the blades so they'll relax & hopefully match each other a little closer. To match pitch, lay them flat on a table & compare.

Thanks, much appreciated!

But, don't forget too - mistracking is ok if there are no other flight issues. If it's not wobbling, toilet bowling, or circling, then having the blades off track a bit is just fine.
