Concerning this model... I thought it was interesting, nonetheless, to see the performance difference between the A3, the A10, and the A8.

And to be honest, that surprised me as well.

You still gotta admit, 170' on a tiny 13mm motor, for a BT-55 body tube, is still a lot of performance! The A10 is the 13mm motor for this brute [snip] deploying near apogee.
For the 18mm motor range, the B6-4 is the motor of choice, for the same reason. Deployment V of 6 fps.

The B6-4 is also just about perfect for my BT-55 1.36X Estes Wolverine upscale, as well, with deployment of 10 fps at an altitude of 313 feet.

(heavy sigh) Gotta rebuild that one. Maybe I can finish throwing my Thunder Awk together and paint it for this month's Tripoli Idaho launch.  
Cheers,
