Interesting. Since the total impulse is so similar, do you have any thoughts as to the difference in heights? Lower weight? More optimal thrust curve?The B6-6W I flew was in an Alpha...and it took it to over 940 feet! Granted, we were starting at 8000 feet MSL, but still....that's crazy height for a B motor. The very same model, with the same type of altimeter in it, has done 630 feet twice on an Estes B6-4 when launched from near sea level and 20 feet or so higher on a Chinese Quest B6-4.To be fair I should fly it on an Estes B6-6 here.
The B6-4W I flew was in my currently active Nova Payloader. It went to 465 feet. Here near sea level on Estes B6-4s typical flights of that model are in the ~275 foot range.
Lower weight (a little) would be a factor. Beyond that, until I can fly some of them here so as to take out the effect of the high launch field altitude at Alamosa, I don't know.Interesting.

Does Aerotech have a resource for reload delay grains for hobby line motors? I bought packs and packs of reloads over the last 20 years. I've heard the motors themselves should work fine, but the delay grains should be replaced for reliability.
Soon... ;-)What happened to the "NEW" G8ST and G12ST that were recertified a few months ago ? I know you said release would be "later" ... . A number of Vendors have the H13 both with and without thrust rings, but that is just too many NSec... The G's look like fun...
I will keep checking for them, but an ETA would be nice.
This is for 29-54 DMS motors.What is the recommended minimum length of time delay grains should be adjusted to? There are various suggestions that 4s or 6s is the shortest that can be safely made, but we haven't been able to find an official statement.
This came from a thread about delay adjustment in general.
We probably went that route due to the difference in “touch hole” diameter, which is 1/8” for RMS and 1/4” for DMS. The larger the touch hole, the more likely a burn through might occur with a thin unsupported delay column.The 29-54 are DMS and the 18-38 are RMS.
Yes, the drill and knob are identical. Be sure to double check the calibration before using.I currently have a normal RMS delay adjustment tool. Can I use the drill bit portion with printed DMS and 54mm bodies? I have a launch this weekend, and I want to fly either a K695 or K400 with motor eject, instead of electronics.
There is a 24mm SU Aerotech motor on thrustcurve, is it the same one?Would love to get my hands on some more G110 and G55 24mm SU motors. Anyone know where I can find thrustcurves or .eng files for them (I know they are long OOP).
+1.Are there any plans for 24mm G motors?
Aren't those OOP ?Would love to get my hands on some more G110 and G55 24mm SU motors. Anyone know where I can find thrustcurves or .eng files for them (I know they are long OOP).
The G110 SU and G55 SU are long OOP, I doubt we will see them again antime soon. As for a 24/60 case G motor that probably is impossible due to the volume of the case being to small for the required volume of propellant.+1.
Having a G-reload for 24/60 case might even justify buying that hardware.
Aren't those OOP ?
Are they coming back?
