Need to change the delay time on Aerotech RMS F52-11T

I have a 2.5 lb rocket that I will be launching with an Aerotech RMS
F52-11T. Calculations show it going close to 500 ft. However, the delay
is to long and the rocket will get enough speed to pull 32g's when the chute
comes out. How can I cut the delay time in half? I know machining out the
delay will do it but how much do I need to cut of to reduce delay time by
half.
PS, I know using stronger motor would be recommended but I have some F52s
already and want to use them.
Thanks for the help

I want to launch this rocket at the local high school foot ball field and don't want it to go 1,000 or 2,000 feet and end up in the trees or homes nearby. So I want to keep it around 500 to 600 feet. My question still stands. How do I change the delay to half the time.
Thanks, KT

Hi,
do you know what controlled airspace is at the ball field ?
probably is 1200 feet, but could be less if near an airport.
if the rocket goes into controlled airspace you need an FAA NOTAM to launch it at 2.5 pounds.
another reason for a smaller motor for ya

Complete instructions on legal delay adjustments are on the Aerotech website.
Someone already posted this info.
Did you get it?
Was there something there that you did not understand?
