Looks like this has already been coverd, but I'll throw in my two cents anyway.
I'm translating a large script file, and I've been able to get most of it by myself. But one of the characters speaks in what someone has told me is 'touhoku' dialect.
// よーし!
//はなっから全開で
//とばさねえとな
This doesn't sound like Tohoku dialect to me.
Is the speaker piloting something? If they are, I'd say:
"Right! Looks like I gotta take off at full throttle!"
I don't think it's necessary to include 端から in the translated text, althought if you really wanted to, maybe you could use something like:
"Right! Looks like I gotta start off at full throttle!"
As for the grammar of ~ないと/~ねえと, it literally means "if not~". There's a pun(?) that serves as a good mnemonic for remembering its usage. The pun is コーディネートはこうでねえと, which basically means "Coordination's gotta be this way".
