This is probably niche but could there be a way to sort the propellant grains by diameter on the RCS store?

Also why is shipping so expensive? I understand hazmat but since when is hazmat $51 dollars?

They are listed by diameter within each propellant formulation. I suppose they could be recategorized by diameter instead of propellant type but that would be a lot of work.

Not sure about how the shipping and hazmat charges are divided up. I know we try to break even on our shipping revenue vs. actual cost. Last week for example our shipping revenue was $2,748 vs. actual shipping cost of $2,750.

Update: The current hazmat fee is $39. We charge more for shipping and handling for hazmat orders because of all the other extra costs involved.

K76 liner option....maybe

"AXIM’s mica tubes can withstand temperatures ranging from 130°C to 1000°C for high temperature.... We manufacture high temperature mica tubing in square, round, oval or rectangular shapes.

Our mica tubes are convolute wound to increase strength and minimize seam lengths...

Size: Mica tubes are available in lengths between 3mm and 1000mm (0.19” and 40”) and an inner diameter between 3mm and 300mm (0.12” and 12”)."

If they can't size the tubes look at using slip-plane material or their other products...maybe...
 
Hi Aerotech, I wanted to ask if there are any updates on when the white lightning B6's will be available and whether they will be available in 12 packs. I've been holding off on stocking up on Estes B6's because I think I will like these better...
One week from today is the planned B6W release & available for immediate shipment on Monday, July 19th, and yes they will also be available in 12 packs. Here is a photo of the first ones off the production line today.

Looks interesting. The thermal conductivity rate is important, I suspect it is higher than paper phenolic tubing. Worth a try, though.
 
Pretty close to zero since we don't plan on making any more once the stock runs out.
Yeah, that was the answer I was expecting. *sigh*

I just started flying MMX models again and did a quick T-3-based scratcher last week to fly this past Sunday carrying one of the new FS Comp altimeters. It popped the streamer while going UP at 40 fps according to the data from that flight: https://flightsketch.com/flights/2592/ That flat-topped time vs. altitude curve is a clear indication of an early ejection.

But longer delays in 1/8A black powder motors is far too niche to even think about from your knothole. I understand.

You WILL like them better! ;)

NSL 2021-0141 Superbird launch on B6-6W Q-Jet.jpgNSL 2021-0142 Superbird climbing out.jpg
 
I'll be looking for a 25-pack of B6-4Ws as soon as they are available. Flying those two B6Ws at NSL convinced me!

Me too!

I flew two B6-6W motors at the NSL also. Darn impressive. I can't believe I was getting so pumped up about 'B' motors.

I will take a 25-pack of the motors too! (Are you listening Gary? ;) )
 
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.
