Does anyone have or know where to get the .eng file for the new G77R and G67R reloads Aerotech recently released. I've looked for them on the AT, NAR, TRA, CAR, EMRR and Thrustcurve.com sites but I haven't found anything.
Thanks,
Andrew
Aerotech claims that TMT certified these motors. (Isn't it odd that there hasn't been a word from TMT about these motors?) So ask either TMT or Aerotech for the data.
Note: Thrust curves are in the assembly instrucions available on the Aerotech web site. So you could use those to make your own .eng file. But it will be tricky as there are no gridlines in the graphs.

There was more than a word from TMT, there were many words (see below). The TMT web page does need updating.

Was this published in a super secret location or in public?
What does, "Gary and his group of Elves have been busy and have further fleshed out their Redline set of motor reloads to the non-certified crowd." mean?
Jerry
As Paul said, it will be published soon (on the web).
Always looking on the dark side, aren't you?
It means they are G motors and thus level 1 HPR certification is not required to use them.

No I am asking what it means. It could have several meanings.
It could mean as uncertified units they were beta tested.
It could mean what you imply.
It could mean a couple of other things.
I guess I originally meant to ask whether the document cited was private correspondence (letter to mfg) or some sort of release us mere mortals did not have access to?
That is a reasonable question.

And in what PUBLIC place was this posted?

Actually it's a secret way they have of confusing Jerry. Poor Jerry.

Certified is used in at least two contexts interchangeably.
Motor cert Consumer cert.
I propose a formal terminology change for one or the other!
Jerry
How about going back to the original for both: "approved" motors and "confirmed" users.
Hmmm... "confirmed user": that sounds like some kind of dope-fiend! :)

Why should the TMT web pages be kept up to date now? They certainly haven't been in the past. I sent an E-mail to the head (now ex-head) of TMT many months ago enquiring about one error in the list and never received a reply. The Aerotech J170H still isn't on the list.
G77r with a 4 sec delay? All the reloads are being sent out with the Medium delay only. I noticed this on many net stores about Oct. selling G,H & I motors. They offer a pdk+ delay (single delay for $2.00 to $3.50 extra) if you can get it for the Short delay. I don't know if this is a Aerotech deal or the Hobby shops are keeping inventory down. Ken
AT says only short and long are certified.
Medium can be made short by removing 3/32" delay.
oops!
AT says only short and medium are certified.
Adjusting the delay sure beats the extra charge!!! That's the nice part of Pro38 and Loki motors.
That adjustment (AT) will wake up the legal eagles on RMR , Jerry.
Ken
If AT recommends it ANYWHERE in ANY website entry or paper documentation (and they did at least through 1994), then it is also NFPA/NAR/TRA legal since it is "recommended by the manufacturer."
Jerry
Actually, if you download the instructions for the RDK+ series delay kits, in many cases you can figure out how to "split the difference" using off-the-shelf delay kits for another propellant type. For example, the "medium" kit called out for the H165R (29/180 redline) is exactly halfway between medium and short for the H128W (29/180 white lightning).
Ever wished you could have an H128W-8? It's mathematically possible.
-dave w
Dave W Yes, I've played with those numbers on a linear burn rate to see the odd multiples. But I've also noticed from those instructions that any single delay element will have different burn rates depending on the propellent type. I suppose due to pressure and temperature differences.
I bought out several pkgs of RDK+ shorts ($0.80 a delay vs current $3.50 ea.) from our local hobby store who is no longer dealing in HPR motors due to legal hassle.
Ken
The modal LMR/HPR rocket needs an 8 second delay.
