I've just wired the 120a into my Yokomo B-max 2 with the Bluetooth module.
I was amazed that you can just leave the bluetooth module stuck-in to your car and leave it plugged in. To change settings you don't need to press anything on the ESC, just launch the app on your phone and change away
You don't even need to take the shell off, you can just pull over while running!
I've set-up a few profiles on my phone - 1 with all parametres on 0 (Blinky), One with 20 degrees of boost timing so I can compare and go from there
I used to run a 7.5 in my 2WD, but I've stepped down to a 10.5 so I can take full advantage of changing the settings like boost timing. Should make the car very fair to drive round the infield yet still rapid down the straights
How fast does that kit fan spin as well?! Sounds like my cars going to take off!
