Do you have one of the Ralphco or Fantazia ones to compare it to?

What was the delay and actual time from burn out to apogee?Finally flew it today on a J270W at the WSR703 launch today for my L2 cert. Nice flight up to 3527ft and used a JLCR to deploy the main at 500ft.

I’ve simmed the very similar 4” crayon rocket I used for my L1 (I’ll probably reuse it for my L2) on the AT J270W - my results show it needs at least a 10 second delay though I’d probably go with 12 seconds if I was using a Chute Release, better a second or two after apogee rather than before - but that’s my preference.What was the delay and actual time from burn out to apogee?
I will launch mine with an Eggtimer apogee with motor back up at 12 seconds then,My delay was early at 8 seconds which is what my sim suggested. If I were to fly the same motor again I'd go with 10 seconds. Apogee was also 527ft higher than sim'd.
Will be flying it at the next launch on a J420R and will err on the high side of whatever the sim spits out for delay.

Thanks!
I have one of these pending a build.
Sounds like it sucks to be FAO SchwarzFAO Schwarz had a 5 incher too.
Probably same manufacturer.
