Aerotch and Quest merge?
So I took about 11 years off rocket making due to tons of things but recently decided to get back in it and introduce my son to this awesome hobby....uhhh LOTS have changed I see.
So Quest and Aerotech are merged? Quest no longer makes black powder motors they now only supply composite 18mm motors called Q-Jets? Aerotech makes q-jets now in place of their D 18mm motors. Shockingly Aerotchs actually finally came out with a couple new kits I see. Estes now has F 29mm Black Powder engines!!! Estes is taking polls to possibly bring back the Gemini Titan! Some people are saying the Q-Jet motors arent that great. Why not? Do you think Quest will come out with bigger kits now that Aerotech is making their motors? Man did I miss a lot LOL. |

Carl passed away and SEMROC is no more. eRockets now produces some of the SEMROC kits and components.

Quest has not put out any new rockets in years.

I’ve flown a lot of Q-Jets and quite a few have been flown here at NARAM both on the sport and contest ranges. Aerotech even supplied Q-jet A3-4s for the Fly It-Take It rockets.
In my opinion the A3s and B4s are OK, the C12 is marvelous and the D16 is a lot of fun in the right models. With the progressive time-thrust curve the D16 in particular makes models go really fast, but not much higher than a C because of the increased drag from going really fast. But it IS fun to watch a model continuously accelerate as the motor burns. With the D16 in particular you can really see that.

The D16-4 with the 18/24 adapter (iirc I had to shorten an orange engine spacer but that could be for a different rocket) in my Estes Vagabond is an absolute hoot! It just keeps accelerating...until it doesn’t. I’m developing an addiction to QJets. |

I don’t have a flyable Vagabond at the moment....but I can see that would be a kick. I enjoy putting one of those in the slightly smaller Citation Patriot, which I do have a flyable example of right now. Another is a good ol’ Big Bertha.....I flew that combination on Tuesday on the NARAM sport range. 732 feet.

Is there a booster version of the Q-Jet 'D'?

No, they don't. There isn't a fool prof way to do that with a composite motor. |

I would like to see that software back out the motor thrust curve data from accel data. You may have to know rocket mass to know power. http://v-serv.com/usr/kits/sonic2200.htm Last edited by Jerry Irvine : 08-03-2019 at 07:29 AM. |

Free bonus! Good booster for direct staged BP or pyro ignited APCP uppers. http://v-serv.com/usr/kits/tripletrouble.htm |
