Raideron: The .46 will pull it vertical out of a hover but it isn't real quick. Does it blast straight up like a rocket?....no.

Glowfuel: I am not familiar enough with a TT .42 to really give you educated answers on how it would do on the Twist. Autoguns seems to be more experienced in that area. Sorry. As for Expo I highly recommend it on this plane if you are going to max out the throws. I think I run about 40% all the way around on mine. Expo is not a necessity, but it sure will smooth out your flying.

Happy New Year to you all as well.
