Thank you everyone with the help.Dave, I emailed Charlie asking him to check out this thread and comment.
I recently looked at the aerotech crossload motor matrix and noticed that the 75mm section had shrunk since the last time I'd looked. Did certification fall through for the 75/6400 and 75/7680 reloads or something?
+2.... One of my LDRS flights couldn't use the motor I wanted. Mine have been on order with Wildman for about 7 months.
Maybe I just need to tie it in a knot to use up the extra rubber
So, assembling a AT M1550R for Airfest. Fairly new motor from my main source... This is the second 75mm motor that I've gotten lately that's had this seal disc o-ring that was included in the kits...
Not happy. At least I'm not assembling it on the field...

I'm proud of you Adrian.. most people wouldn't admit in public to needing the smaller diameter.
On another note- here is my regular question about the 29/40-120 red load Any updates on this?
Also- is the 29/40-120 sparky load (Metalstorm?) permanently canned?
I was inspecting a J570 reload last night and realized that the label attached indicates a total impulse of 1060 Ns. This is roughly 10% higher than the total thrust listed on Thrustcurve (973 Ns).
The data on Thrustcurve.org is 10-12 years old, and I seem to recall that Aerotech has been re-validating or re-certifying reloads.
Which data is accurate? Is this a case of a retested motor?
Which thrust profile should I be using? Obviously, a 10% variation could mean the difference between a busted waiver and a legal flight, and I'll be playing it safe, but in the interests of accurate simulations...
Thanks
I do believe you will see the 40-120 redline reload available before the year is over. .
I had misplaced my 2 second delay drill spacer. I think I found it. Can anyone confirm its size. My calipers read about .056".
Rule of thumb for delay drilling is 1/32 inch per second so in theory it should be .00625 inch.
Correct, but that bit of a difference aint going to make a difference!!
In fact I just measured my spacer and it is indeed .059 in thick
Sounds close enough to me... And I assume the washer would be the same between the DMS Universal delay drill tool , and the RMS RDDT?
The I180W for the 38-360 case is a great reload and is also without hazmat. I wish they would come out with a similar reload for the 38-480 case.

Don’t forget that most of the 29mm reloads are hazmat free ( except the black jacks ) so there is more simulatities.
