Yes

I am using 720mm blades with 107mm tail blades and the result is, well, crisp.

I have an excess of power and this is with an engine that hasn't been leaned out yet (still breaking in, running at about 174 degrees max).

I would imagine that the 690mm blades will not fully work the engine.

This is at 11 degrees of collective pitch at both ends, and 7 degrees of cyclic pitch.

The autorotations with the 720mm blades (192 grams each) are simply amazing.

oh

Oh yeah one more thing, the stock paddles (white 3D paddles) are great!!! I hated them, and used V-paddles for a while, until I learned the secret for making the white paddles stay on tight:

First thread the paddle by screwing it onto the flybar all the way, then remove the paddle. Apply silicone RTV sparingly to the threads of the flybar. Scrape any excess RTV that extends higher than the threads, and allow the silicone to dry fully. Now screw the paddle on. It will go on a lot tighter and it will take more force for it to move after you set it into place. But when necessary, you can still remove the paddle without leaving behind a mess inside the paddle and on the flybar. This is better than epoxy (or nothing).

i am fairly certain that 690's are scoles choice on the tempest. they are ballistic, and i haven't seen him have any problems with running them. his heli is very quick...still has lots of hang time in autos.

Coming at the math another way, JK (per his equip. specs) is running 710mm or so blades on his models with the Expert/ Extreme head. If you run 690's with a Tempest head, you're within 6mm of the same overall disk diameter.

"Tempest head is 17 mm wider on each side than the normal XL head. "
