For anyone that sees this in the future I now realise a 45a esc is no good for that motor and a 3S. My theory was I believe wrong, the current draw is constant and not related to voltage so the 56a motor is over the ESC’s capability.
Naturally I’ve fixed it by ordering a 3800kv 3660 60a combo, the 3660 will squeeze into the TT02B with its 120a esc, it didn’t need more power but soon it’ll have it.
That leaves me with a 60a esc and a 3100kv motor for the DN01 and a 45a esc and 4300kv motor for the spares bin. I am concerned it’s too much on 3S but I don’t want to buy another battery at the moment so we’ll see what happens.
