That's great news. Given the 60g propellant mass, presumably under 62.5g TEW, this must allow them to be shipped in the same hazard class as you already ship E15 motors. This is definitely a total departure for Estes similar to but quite better than the FSI F7. HAPPY THANKSGIVING 2012! So are you also going to make a 39-40 N-s "full E" or is that too much product fragmentation?

That's 3.45 sec burn time. To me that short of a time reduces many of the concerns I had for even fatter streamlined models. No Saturn V's here (except maybe piston launched ), but I can see why John says the existing Pro line of kits will fly with those. Being BP the prices ought to be somewhat similar to the E15 on a per gram basis.

I will really be curious to see the new casing. Maybe I'll buy 10,000 of them and make some APCP motors with them. I did some successful experiments (customer deliveries) with 24mm APCP in spiral phenolic and NOZZLELESS motors (certified!) in traditional convolute wound cases.

These fit in a very wide range of U.S. Rockets kits. 4x as many kits as Estes offers. Masking tape thrust ring! Check out Sonic 160 (BMR2 series) and Two the Limit (AMR series). Everyone needs a Screamer! BMR2 series and available now from USR or Bellevue Hobbies email= sales@bellevuehobbycenter.com .
