Hi Gus, if ya have room for me count me in. As many know large dark matter motors are my motors of choice so couldn't pass this up. Thankyou for putting together an awesome drag race for MWP 12 that will be remarkable, good job GUS, can't wait to see this spectacle, should be a real crowd pleaser.

So do you have a who's who of who's in the Sparkie race.
Gus, did I do something wrong to get booted from the field? I know I was in it before.
"We now have the following add on's to the listing and, thank-you for your participation!
7. Jim "The Underboss" Scarpine.
8. Tim "Big Bucks" Dixon.

I believe rules are 3" Sparky in 4" airframe; my guess is if your aren't flying 3" motor you don't qualify(?).
Wow... I just crunched some numbers on this... assuming 15 people are in the drag race, all flying baby M's...
A baby M has about 6000 N*Sec of impulse. 15 people flying means that 90,000 NSec of impulse is flying simultaneously. That is a baby Q motor. Now, for cost. A baby M... call it $220. 15 people doing this simultaneously... about 3K up in smoke. Now, considering an average L3 rocket is about $2000 on the pad... about $30,000 of ROCKET will be flying through the air at really freaking fast speeds (except for Scarpine... his will barely get off the ground.... you know how he likes his sparkies... low and slow... )
A small M motor looks to have about 8 pounds of propellant. That is 120 pounds of titanium sponge propellant... burning simultaneously.

"Evil Twin"
It was until the clearcoat blistered the paint. First time I've had that happen. It will still fly. I stopped before doing the booster, mach will peal the pinstripes off without the clearcoat.
I'd stick a K or L Sparky in it and, just join us for the debauchery! Preston....Eric? Got some bits and, pieces for Curt here? I'm sure they might have enough "Cutoffs" that a say......*20 grain K* could be whipped up into a short liner.
After Fridays maiden voyage at mach 1.5 plus on a CTI M-............, no problem with loosing a few more pinstripes and shredding off more paint on if I were able to get in another "M" flight on an EX-M Sparky
