I can't wait for you to get to the track! Thanks for the killer updates! One FYI with the air launchers if you've never used them. Make sure that no part of the bag can get hooked around that push disc as it will bend the plunger upon deployment. I have had it happen and was able to bend the plunger back with it still on the car. The first time it happened it was pretzel salad and we had to replace it. The plungers sometimes hang out after a run and with a little twisting and hand smacking will return back down. Make sure if you have to twist it that the nut is tight enough to turn the plunger and not just the disc. The bags get torn up pretty easily and we've used 200mph tape on them for awhile until they were too tattered and were replaced. They are simple to pack and I've actually got them ready to go with no string. I highly advise getting used to chucking one or both of them out BEFORE the stripe.
