Big weekend of testing! Saturday the weather was decent, upper 50's, sunny, no wind. Went out to a new spot (in a stadium parking lot). It had plenty of room for 66 or 132 ft hits, but I was sticking with 66ft until this thing would get a to b consistently. The surface was clean, though typical rough asphalt.
I started off with a super conservative "concave" tune, still at 30% power, and the slowest I could make the throttle go. I knew it would be slow, but I wanted consistent first. I got a couple of hits in with this tune, all were 1.9s at 38-39 mph. Then I did a "dumb thing", and turned my car while it was going too fast, cartwheeling it. I didn't have the body on (thank god), but it broke the wheelie bar mount adaptor (a 3d printed piece). No other damage other than a scratch on the cooling head. Went home, 3d printed a new adapter, and decided to go out the next day. Really have to get out of the habit of instinctually turning the car, and just let it slow down gradually to a stop before turning.
Well, the weather took a nasty turn. Low 50's and overcast. Windy as hell, with a pretty serious wind chill. Gusts were 30 mph. I was not really prepared for that - and had trouble getting the engine to a good operating temp. I was determined though. I started dialing up the throttle rate, and over the course of about 10 hits, got it all the way to 100%. Then I started dialing up the throttle speed, and moved it to 60%. The car was launching noticeably harder, times were getting down into the 1.8's and 1.7's. I was hitting the low 40's, which is pretty good. The g's were 1-2 for the most part throughout the entire time I held the throttle down. I only have one screenshot to show (more on that later). Pretty steep accel curve here, seeing 1.59 g's at 0.4, compared to 1g at 0.8 with the OS .21 tm that I was seeing before with the single speed trans.
I started moving the throttle exponential less concave and more linear. I was no where near the steep convex curve that I was using a couple weeks ago, so I wasn't quite as fast, but every hit was straight and consistent. I bumped the idle-up to 15%, and the trans brake held it, and was doing some seriously hard launches. I started getting into the 1.6s at this point, and upper 40's. I could definitely tell the car was getting close to the traction limit, as now I had to "drive" it a bit, but overall it was pretty straight. I should add that at this testing spot, there's a very slight sideways lean to the surface, so it's kind of fighting that to keep straight with some steering trim, and that is surely hurting the times a little. I like the spot though because nobody is around at all most days. My best run was 1.64 at 47 mph, and it cracked the 2g mark. Sorry I don't have a pic. I thought my GNSS was going to keep all of the records. Sadly (very) it did not. I know now to always swipe left to get a screenshot because you can't trust the app. At least I swiped the earlier run. When I got home I tried a bunch of stuff, and then just tried to fix it by clearing the cache, etc. Nothing worked - it wouldn't show the records, only the last thing you did. Then I uninstalled and re-installed the app, and it started working again. Too bad I cleared my cache
I'm still a little off of my goal to consistently hit sub 1.5's, but I need to try on a flatter surface and a better, warmer day. 1.5 is supposedly the "magic" number for 66ft passes according to the experts to be considered "fast". 1.2's are what the very fastest in the country can do in 66ft.
Meanwhile, my day ended after my brake adapter sheared after setting the brakes up a bit higher (again, better that then the transmission shafts). I had spares, but the wind was now howling at 40-50 mph, it was time to go.
Need to sand down the rough edges yet. I think I'll also leave it clear, I kinda like the look. 
The softer compound tires were way stickier too. Mostly I spent my morning getting the tree and stuff set up, but I had about an hour to kill before the rain hit.
