What a match - congratulations to both of you and your teams!

For both Al and Marco - what are some engineering/design/fabrication aspects of your bots that you're proud of, but that have been glossed over in the making of the show? Particular mechanisms you think are awesome, or systems that took a lot of tinkering to get just right?

For Marco - do you send your drum out to get balanced? If so, where, and what is that like in terms of cost, turnaround time, how surprised the shop is by your request, etc.?

Whoo, hooray for hammers! Oh boy, I have so many questions about your flame system. I am really impressed that you made it work inside the hammer at all! No worries if you don't want to answer all these....

When do you ever use the low propane flow?

Are the two igniters mostly for redundancy? Do you have the igniter in a little pilot tube or does it just spark into the main flow?

Do you have any sort of grating or other turbulence/mixing-inducing system in front of the propane outlet to get enough air in there to light?

Is your propane valve in the hammer head, or in the main body of the bot with some awesome long nozzle?

Wow! I'm impressed and surprised that balancing by hand is good enough to go up to 10,000+ RPM. Thank you!
