P73-P76 Blade numbering

I had put some new pro-woods on the Trex and had tracked them perfectly. They are so much nicer than the standard Align woods I was using. The Trex seems much more stable.

I had to take them off to change out the main gear (yes, flipped into idle up on the ground AGAIN! grrr).

When I put them back on, I noticed that they were not tracking very well. I had a hunch that I had switched positions with them in the grips so I exchanged them and sure enough, they tracked perfectly.

I've now marked the blades and the grips so that I can always be sure to match the blades with the grips.
