After seeing other's trakpowers and getting feedback on here, I also took the plunge and went lipo.
They came off cold to the touch after 5 minutes racing last week, although I struggled to get the power down.
I bought the 4800 saddles & 4900 stick and they have stupid levels of punch, if I hit full throttle in my B4 it just flips onto it's roof and that's with a 7.5.
I also have an Orion Platinum 4800 stick, even though that's 'only' 15c it's not much different to my trakpowers.
Wish I'd bought them earlier, have just bought a 10.5 to try and get some steering back
