Ok, I just tried to measure headspeed with a tach, and it's reading 4000+. Now, this can't be right. Is there something I don't know about reading headspeed with the kind of tach you point at the blades?

Align 430L motor, TP 2100 mah pack, 11 tooth pinion.

Wow, the ground was closer than I thought.

Yeah, I tach my blades out toward the tips, with a blade (airplane) tach and if I go too far in, it catches the flybar paddles as well. If you cant get it down, you might either set it yo 4 bladed prop or just divide the number by 2... a 4000+ HS is actually 2000+... and so forth... not as pretty as with an optical tach, but it does its job in the end...

But Honey, I can't live with just stock.....

Yes, it seems to have been the light source that was screwing it up. Did it out in the sun, and all is well.
