For starters, a massive thank you to everyone who has volunteered to be a part of the Scuderia Kouba circus this year- and specifically, Jeff Burns and Beau Frazier, who along with Bill Bostic will be covering our official staffing obligations with the event organizers. For everyone else who will be helping in the pits, etc... thanks for being willing to give up your Saturday in August!
Thanks to everyone for making it out for push testing. I think we learned good things and the exercise was worth the effort. I was disappointed my lightweight pushpoles didn't exactly pan out but I was glad the other one will. It was also good to learn that the pusher can't cross the line (although we should seek confirmation on this- it made a ~2mph difference to speed at launch). Getting the starting blocks set up was also a good accomplishment for the day.
For the crew that headed up into the hills with us, again, thank you for your time and energy. This whole exercise makes it clear that this is not something I could do without the help of others. It takes a village to get this idiot to the races, so thank you for your help.
As for the testing, we were investigating the differences between standard wheels, wheel disks, and wheel pants. For the first run, the MkI had spoke wheels and the MkII had the disks. Bill has already posted the results:
Test Run No.1
MKI 37.1 MPH - Chris
MKII 36.7 MPH - Jeff C.
For the second run, we swapped wheel sets on the front axle and saw some pretty consistent results- MkI went up ~1mph, MkII went down ~1mph:
Test Run No.2
MKI 38.0 MPH - Chris
MKII 35.6 MPH - Jeff C.
For the third run, wheels were swapped back but I put the pants on the MkI. The MkII had a driver change and was run down the hill without its canopy on. The MkI went up .4mph and the MkII set its new baseline
Test Run No.3
MKI 38.4 MPH - Chris
MKII 36.4 MPH - Jenny
For run 4, the MkI had a driver swap and the canopy went back on the MkII. Jeff was able to squeeze another .7mph out of the MkI and the canopy improved the MkII's top speed by 1.4mph.
Test Run No.4
MKI 39.1 MPH - Jeff
MKII 37.8 MPH - Jenny
I wasn't aware of any changes for run #5. Jeff eeked another .3mph out of the MkI and Jenny had another strong run as well
Test Run No.5
MKI 39.4 MPH - Jeff C.
MKII 37.5 MPH -Jenny
And the icing on the cake, on the ice cream... 14 miles of bliss! I was able to carry the speed a little lower down the hill and managed to get a little further than last time, but there's a mild incline where we come to a stop and I couldn't clear it. With a little more confidence in the sweepers, it may be possible to carry enough speed to clear it, but making the run to there is certainly a treasure in and of itself.
Final Mountain Run 14.6 Miles
MKI 62.3 MPH - Chris
MKII n/a - Jeff C. (managed to leave the start without a GPS. What?!?!???!)
The flyer was deceptively slow at this venue. We know it's a fast entry, but the pavement at the test site, while it was smooth and unbroken from a macro perspective, was fairly rough on a micro-level and it hindered the ability of the flyer to reach its full potential. As we saw last year, the smoother pavement at Mt Tabor will bring this sled to life though!
Hawksbill Flyer MPH - 30.7 - Jeff B.
Hawksbill Flyer 33.6 MPH - Rico
Hawksbill Flyer n/a - Dennis
So by the end of the day, we had determined our final configurations for each entry. The MkI will go down the hill with its wheel pants on and the MkII will run with wheel disks and canopy. If the derby was tomorrow, we'd be ready to roll!

I know Jeff C and Jeff B both took some video and I am looking forward to seeing some of that!
Thanks again to everyone who's been a part of this. It'd be a lot more work and a lot less fun to have to do it without you!
