I liked the new B14T ad on the back cover of the May/June issue of Sport Rocketry.
Haven't seen the magazine yet (it will probably be a week or more) but Yes! So.....about when can I actually buy some? I've been checking the Aerotech web site every day since the certification announcement.I liked the new B14T ad on the back cover of the May/June issue of Sport Rocketry.
In the process of designing a 75mm min-diameter beast around the RMS-75/10240 case. Any dimensional info available, or will just scaling in an additional grain length do the trick? Need data I am confident in because of the retention design! Checked RCS but nothing showing up yet.RMS-75/10240 M2700W-PS TRA certification. This motor was developed for the upcoming $10,000+ AeroTech Space Challenge contest.

Here you go. (From the less-organized bottom section of the RMS dimensions page)In the process of designing a 75mm min-diameter beast around the RMS-75/10240 case.

Thanks a lot for the clarification. I was aware from hearsay that things somehow got more complicated but had no understanding of the details. Not a fun document to read, though.Larger than 5 pounds propellant each? A U.S. State Department Export License is required.

THANK YOU! Was on that page, but have never scrolled down that far. Guess the best place to find paydirt is down deep.Here you go. (From the less-organized bottom section of the RMS dimensions page)
It has not been released yet.Anyone know the status of the AT J1265? I was looking into high-impulse motors for a maiden flight on a 15-lb FG rocket this fall. Based on lead times for motors, I'm trying to do some pre-planning.
This thread announced the certification of said motor. The current Aerotech Motor Matrix lists the motor. But all the major vendors seem to not have it catalogued in their stores (that includes the manufacturer, Aerotech) as if it doesn't exist.
The RMS J1299 seems really close to the same motor, but requires hardware that I have yet to procure. Any info out there? Thx.
Those didn’t sell well. That case needs a high burn rate propellant to be useful, hence the K750ST. We could try Blue Thunder in that case.The 75 mm K1499N was an awesome reload. Is there a plan to replace it with something similar - perhaps an X variant? The 75/1280 motor is pretty lonely.
Well, if it's like the prototypes Gary showed before, it's 4AA cells inside.I am curious. Is this powered by an internal battery or do you attach an external battery?
I sure hope its more the 4 AA Cells.... I am looking at this product as something that can potentually replace my current personal launcher which I built in high school in 1999. If it is just 4 1.5vt cells, Maybe I'll use it to drive the relay in my current box...Well, if it's like the prototypes Gary showed before, it's 4AA cells inside.
Even so, I'm looking forward to this gadget.
I may have imagined this after a couple too many beers, but I thought it used a 9V battery. Seems I remember discussion about getting the correct one (with the cylindrical cells, not the layered flat cell versions). Or using a lithium single use 9V.Well, if it's like the prototypes Gary showed before, it's 4AA cells inside.

The little handheld Phaser from Aerotech uses a 9V battery and the documentation supplied with it directs you to use a lithium-based 9V battery. That drove the whole 6LR41 cylindrical alkaline cell vs stacked pressed cells vs. lithium in either cylindrical or pouch cells discussion AND my R&D for the vNARCON this past January as well as data shared in that big 9V battery thread.I may have imagined this after a couple too many beers, but I thought it used a 9V battery.

Or I could be wrong....
Hans.
IIRC, the preliminary info on the iLaunch (that's probably up in this thread from the winter) calls for lithium-based AA cells. This MAY drive me to conduct a similar set of comparative tests on 4 AA cells (I have the equipment I need and some "test victim" cells as well as a pretty good supply of Estes Solar Starters contributed by another TRF member on hand) but this is lower priority for my rocketry time until after NARAM.I sure hope its more the 4 AA Cells....

The hand held unit for iLaunch is your phone or tablet....that's the whole point of the thing. What Gary showed in his post is the pad box.I would expect the hand held unit to be powered by 4 AAs or a 9 volt. All it needs is to get the signals to the pad unit. The pad unit will need a high current battery. Large 3S LiPo or lead acid for the starters.
This has been mentioned before, but it’s powered by 4 X AA primary lithium batteries.I am curious. Is this powered by an internal battery or do you attach an external battery?
The nice thing is that the new Q-Jet B14 has time delays; 3, 5 , and 7 seconds.I liked the new B14T ad on the back cover of the May/June issue of Sport Rocketry.
I would be REALLY cautious with the protection circuit that is in these (per the Amazon page) and what its upper current limit is, as well as how quickly it kicks in, to determine if these would be suitable for the iLaunch (or an Electron Beam or other 4-AA-cell-based launch controller). As I mentioned before, I may go down that rabbit hole later in the year, but not before NARAM.Yeah, I probabily saw that but its been a while and forgot about it.
How well does it work with Rechargeable Lithium Batteries? For example:

The nice thing about the new AeroTech/Q-Jet B14s is that they now EXIST! Thank you, Gary, et al.!The nice thing is that the new Q-Jet B14 has time delays; 3, 5 , and 7 seconds.
And it will be even better when we can buy themThe nice thing about the new AeroTech B14s is that they now EXIST! Thank you, Gary, et al.!
Q-Jets are not available in Canada, period. I really wish they were but our regulatory bodies are a bear to deal with.And it will be even better when we can buy them
Your vote matters. . .Q-Jets are not available in Canada, period. I really wish they were but our regulatory bodies are a bear to deal with.
That's too bad. Some of them are quite lovely motors and I'm expecting the B14T to be among them.Q-Jets are not available in Canada, period. I really wish they were but our regulatory bodies are a bear to deal with.
Hey, Bob — how come you're talking about the ad on the back page snd didn't say anything about my wife's article in that issue? We got ours today.I liked the new B14T ad on the back cover of the May/June issue of Sport Rocketry.
