to drift a lot more than a normal drogue-main deployment would, but that's better than having
your rocket impact the ground at high speed, and/or having the main chute shred because the
deployment velocity is several hundred feet per second, and still having a high speed ground hit.
The proper values of the Failsafe parameters will depend on the size of your drogue chute (or
lack thereof if you're going drogueless), the size of your Main chute (if it's large you may want to
deploy it a little slower to avoid damaging it), the size/weight of your rocket (smaller lighter
paper rockets will fall slower), and how your other channels are set. If you are going to use it,
100 fps for 1.0 sec is a good starting point assuming a standard dual-deploy rocket with a drogue
chute with a 50-70 fps descent rate. Note that if you have multiple channels set to Main Mode,
you can enable Failsafe for more than one of them, we recommend that they're separated by at
least 0.5 secs to prevent overpressurizing your main chute payload pay (assuming you're using
multiple charge wells).
Airstart and Clustered Settings
Airstart and Clustered modes are typically used for firing motors or separation charges while the
rocket is moving "up". There's a lot of complexity that goes along with this, so see Appendix B
for a thorough discussion of Airstarts and the Clustered mode.
