1 Mega Cowabunga, 2 months, 2 L motors

I'm behind.  I therefore deem it appropriate to place my April and July 2018 Lucerne flights in a single blog post.  'Cause that's how I roll.
     This Mega Cowabunga simply rules.  It's of a stubby aspect ratio but it's diameter is eight inches.  And is has a 98mm motor mount screaming for increasing thrust.  It's inaugural flight was on an AT L1500 Blue Thunder and I've continued with increasing thrust.  In April I flew it on an AT 4668L2500 Super Thunder.  In July I flew it on a CTI 4807L3150 Vmax.  The vessel takes that accelerative abuse like a champion (full-screen viewing remains recommended):

Both flights were very similar. Rapid ascent off the pad, ejection at apogee, gentle unfurling of the 'chute via deployment bag, and recovery less than one mile away on the lake bed.   Flight didjits:

AT L2500 Super Thunder
Max acceleration: 19.355 Gs
Max velocity: 765 ft/s
Max altitude: 5719 ft AGL

CTI L3150 Vmax
Max acceleration: 23.38 Gs
Max velocity: 871.5 ft/s
Max altitude: 6407 ft AGL

I think that Super Thunder has become my favorite punchy propellant of late due to its excessive flame length.  Unfortunately I failed to catch a photo of that in April but I seem to remember it being over 15 feet long.  I did, however, get a sweet sequence of the L3150 ascent and here's a peak shot:

I've ordered an AT M4500 Super Thunder so you know what's next.
