My son has a sx mini 350j with TC, and it DID NOT have preheat that I can remember. Not sure about the "newer" boards from them.This while being a bit off topic is probably a good place to get the answer to my question.
My Dicodes has power boost but not in TC mode, what about the Yihi TC boards, do they have preheat in TC mode?
Aside from all the other great features of the modern dna boards, the preheat in my mind is the top feature. I'm just wondering if "they" are catching up yet.
