added Final Check section
The H550 motor puts us at an initial launch acceleration of 30g’s, approximately 90 ft/s off the launch rod, so anything inside the tube will shake uncontrollably and possibly break. It will also cause the parachutes and other stuff in the rocket to be shoved down the tube. Be careful about how you attach the coupler as screws can catch the parachute and make it fail. Ask Ian on how to explain this to the safety officer!

=Final Check!=
Are you ready to launch? Run through this quick checklist!
==L1==
*Is your parachute packed correctly? Kevlar wrapped around? Is it attached to your rocket?
*Is your airframe bolted together nice and tight?
*Did you buy the correct motor? (H or I Motor - MUST BE 38mm)
*Did you pack in black powder for motor delay ejections? Check the delay time.
*Does your nose cone slide off with vigorous vertical shaking (with the motor assembled)
*Is there any epoxy that has not dried? (Wait if there is)
*Is your certification form and flight card filled out with rocket info? Do you know your NAR/TRA membership #?
*Did you pay your launch fee?
*Are your rail guides properly mounted on your rocket?
*Is there a pressure ventilation hole so your recovery system doesn't prematurely deploy?
==L2==
In addition to the last 6 items listed under the L1 check,
*Are your parachutes correctly packed and attached to the avionics bay (and nose cone)?
*Did you buy the correct motor? (J or K -- if you're not using motor ejection, don't fill with black powder)
*Are all electronics functioning? Fresh batteries? Easy switch access?
*If using a barometric-based altimeter, have you drilled a pressure-access hole for it?
*Have you loaded up your charge wells?
*Have you checked the position and attachment of your igniters?
*'''Are your apogee and main charges facing the correct direction?'''
All good? Great! Get a photo of you on the launch pad before your rocket and good luck!
