staging with quest motors

[William Dieckmann]

Can quest motors be ignited by Estes BP motors or vice versa

The old black powder one can... but the new Q-jets. No.

The composite Quest Q-Jets cannot be ignited by BP.

If you read far enough, there are some people who have had some success lighting BP motors from the ejection charge of composite motors. However, you cannot buy composite motors with -0 delays. So you're either into drilling delays to non-certified times (also, AT/Quest does not recommend drilling the delays on Quest Q-Jets), so that's EX territory, or you need to do some very careful sim work to ensure that your rocket will still be sufficiently vertical at the end of the shortest available delay to make igniting the second stage safe. In general, this is likely to only work reasonably well with extremely high-thrust, short-burn motors such as the F44.

No. You'll need electronics for that... preferably some kind of altimeter with an airstart function and some kind of safety lockout if the rocket isn't at the appropriate altitude/velocity/angle at the time of ignition.

Thank you guys that is what i though just making sure

one more question, will a BP motor ignite a quest Qjet?

 

[SolarYellow]

No.

one more question, will a BP motor ignite a quest Qjet?

Q-Jets are made with composite fuel that needs to be ignited at the top of the fuel grain.
