[BProckets] 80:20 BP motors - REPORT.

[flint hapirat]

Hi all,

My regular (end burner, 10mm ID, 5cm long, 2.5cm long
core) BP motors require a 2-2.5mm nozzle (depending on
milling time). The 80-20 BP was milled for 2 hrs and
the rocket took off on a 2mm nozzle ID – just like my
regular BP. Beautiful flight no problems whatsoever.
It seems that there is no significant difference
between the two compositions 75-10-15 and 80-20 at
this level. Bigger motors may allow us to see a
difference in performance, but not at this scale
 This
BP works just fine.

Cheers, 
Flint
