picked up one pack each of the C12 and D16 motors, have some heavier models and curious how they'll fly on this, very short burn times but looks to be a good punch off the pad... We'll see..
Pre-orders only, shipping mid to late August.
I modified Venus Probe and Exoskel rockets with 24 mm motor mounts just so that I could use D engines.Here's hoping for mid-august... Looking forward to the D's especially. Have a vintage Venus Probe thats waiting for that one. Flown in on a D-21 and it did well
Yes, they are progressive,but when the D16 starts with 2N higher thrust vs the C6 and then goes up from there, it will fly a heavy rocket designed for a C6 much better.
I tried doing the same comparison from thrustcurve.org and couldn't figure it out. It is interesting that rocketreviews shows higher peak thrust for the C6.Here is a graphical comparison of the Estes C6 and the new D16:

The interesting thing to me is how the Q-jets spool up so quickly compared to the BP motors. I would *think* that would translate to higher velocity off the rod, which would be very useful for heavier models.Here is a graphical comparison of the Estes C6 and the new D16:

On the other hand, I would like to see the same picture comparing a D16 to a C11.

I really wonder what the engineers were thinking with some of the Estes designs that were designed for 18 mm. IMO waaay underpowered. A reasonably priced 18 mm D would be nice.
I was just looking at the first graph posted by Domansky. There are 2 more by John Coker that are more accurate and match the published info from NAR testing.RocketReviews.com lists 14.09 N as the max thrust of the C6 while ThrustCurve.org says 14.10. Pretty close.
The graph at RocketReviews.com doesn't round off the peak in the graph of the thrust curve, so the plots look different.
I heard from a fly on the metal post of the NARAM pop up that the published thrust curves were conservative and the hope was these motors could be used in most Rockets using a D12! Having seen them fly my skepticism was tempered. Would I put it in my Mars Lander? Yes. My Rock-it? Yes My Titan III E? Maybe. My Noris Vostok? No.
Maybe they think they can get a bit more umph in the future?
I like these comparison charts. How how do you do the chart? What about a chart comparing an Estes D12 compared to a Quest D16?
Thanks in advance.
These were manufacturer's demo flights. Had to fill out on the flight card and prep rocket at the table. They inserted the new shrink tape igniter. Still working out potential bugs on securing the igniter so I was careful at the pad attaching the leads. It held in just fine. They will tweak the ejection charge back up on the short delay motors.
The ROCKETREVIEWS site does the comparison.. you pick the motors, it creates the graph and chart.
Here's the Quest D16 Q-Jet to Estes D12: https://www.rocketreviews.com/compare-motors-464170.html
Look at the bottom left of the page, click on "What You Can Do".
It is indeed. Thanks got to Roger (Jadebox) for turning us on to this feature.Dude, that’s so sweet!

Thanks! It all makes sense then.
I built an add on section (sort of like a booster section, except instead of an upper stage engine the 24 mm engine in the bottom section just blows through the fin can to pop the chute.)I have an exo-skell sitting in box, as after flying my venus probe it was obvious I wanted to put a bigger motor mount in the exo-skell... However it has one of those ABS Injection molded fin cans with integrated motor mount.
How did you go about getting a 24mm in there, did you ditch the stock fin can and build your own?
