Volts definitely have turn, but it is manageable. They do not have TB stability. Just today I threw a Volt 10' high, slight hyzer release and 75% power in a very mild headwind and got a gentle turnover out of it, parking a 280' hole. That's one of the selling points of the Volt for me. Stable enough that the turn can be masked with clean hyzer releases, but the turn can also be exploited for a huge amount of technical lines.
If you watch this video from the very first day I threw a Volt, before I was used to them even, you'll see a 370' hyzer at 1:50, followed by me throwing a slightly less accurate version of the line I just described above. Clearly not a teebird.
