I started out on the 323 software, with everything cranked to the max and it felt pretty nice. then jumped to the 110, and that, to me, didn't feel as good even with the timing turned up. Seemed to lack the grunt off the turn. Then going to the 107, initially kept the DRRS at 7, and timing at also at 7. Was an improvement, but not quite there compared to the 323. Like i said before, ended up putting the timing up to 8, and this performed much better, better top speed, and good rip off the corner.
I didn't check the temps, as it was only 5min heats, but motor was only slightly warm to touch after the run, so I think there is more to come yet. Will be taking it round a bigger track this weekend, hopefully with other cars on the track, so I can gauge the speed better

As for the other stuff, nope no reciever pack or booster. Initially thought I might struggle with BEC, as I'd been having some trouble with my spektrum recently, and had resorted to the spektrum cap in my TC to solve it... however this weekend it reared it's head again, and the cap didn't help in the 12th. Thankfully, traced it down to a wobbly module fit in the transmitter (something the KO Esprit3 and spektrum modules seem to suffer with)... nothing a few strips of tape can't solve
Ended up taking the cap off, and had no issues, even after I put the PT in the car too. Ran fine all day after that, just removed the low voltage cut-off in the settings.

Overall very happy with how reliably the car ran, and had a good opportunity to test the new software in a different application. I'll be starting off with it as is for this weekend (albeit at a higher mmpr to start with), and make sure to come back with my progress

Just too add, over here in the UK, 10.5 is our stock class, and so far 1s LiPo isn't really an option.. it's only just finding it's feet in modified. I don't know if it's just me though, but I felt more than comfortable with the speed of the car, I don't know how you guys run 17.5 1s in one of these... I'd fall asleep!!

Cheers
Ed
Did you consider that the new 107 and 110 require shorter gearing compared to 323 and 312. You need to drop a few teeth to benefit from the better bottom end and speed.
Thats what i have experienced with my TC. I have dropped by 6 teeth.
