Raptor gears

Is the one on the left V1 and the one on the right V2?
My tail blades stop spinning on spool down so I'm guessing that the tail will not be driven on auto's, correct?
Will the V2 change that?

The one on the left is common to both V1 and V2 Raptor 30's. This is the one I have in mine. The Raptor 30 never had a driven tail for autos. The one on the right is from a Raptor 50 V2. Since I never had a true Raptor 50 I've never seen one before. This will provide tail control (rudder) during autos. Why are you going to start shooting autos??? Make sure you practice those out in the open. A 30 size heli comes down pretty fast giving you one shot at getting it right. Not a good thing to try while flying amongst the trees.

I was just wondering what the difference was, the one on the right has a bigger main gear.
Do you have any use for it?

Hang on to it in case you ever upgrade yours to a 50.
