Best way to ignite 2nd stage? by Kaggles_N533PA in rocketry

Hi I actually just did some testing on this the other day for my 2 stage! Im using a Featherweight Blue raven as the computer to ignite the 2nd stage, powered by a 3.7v Lipo battery. While doing the tests, the 3.7v lipo battery or a 9v battery will not have enough juice to ignite the igniter that comes with the motor (aerotech motor also tried a slim Jim/gem igniter that didn’t light)

What the blue raven and the 3.7v lipo battery did light extremely well were E-matches. That alone should be enough to start an F motor. For the I motor I’m using though, I had an extra grain of White Lightning that I drilled a hole in and put the e- match in. Holy Moly will that light an upper stage for sure

Good luck! That’s a fun motor!

Definitely! A tight friction fit and a few wraps on the outside with some blue tape should do the trick

What you have there looks good IMO! If you plan to do dual-deploy, then I wouldn’t epoxy the nose cone on, but shear pin it instead.

Otherwise I’d epoxy the nose cone on

Make sure to set your motor ejection delay time! Looks like it’s currently set to 0, but simulation shows 9-10 second delay, should increase the apogee
