Default Pro V1, V2 differences

I'm retiring my Align 450 Sport and moving the electronics into an Align Pro V1.

Can someone tell me the differences between the V1 and V2 please?

I want to buy an extended Anti-rotation guide to mount my FBL unit on and have found a cheap one BUT it's listed as a Pro V2.

Will it fit my V1 frame?

Thanks in advance!
Trent

frames are the same with minor differences. v2 have a tray under main gear, anti-rotation and battery tray are extended. main rotor housing sits 10mm lower than v1. Canopy mount have an extra lower step with foam to mount a different style canopy. Everything else is basically the same

Thank you sir! That means the V2 extended Anti-Rotation guide will work in my V1 frame

If you were going to V2 FBL, you'd find that the head has the swash driver (wash out arms) fixed to the rotor head - the V1 has the swash driver seperate and that is mounted about 5mm below the head. It means the V2 has fixed phasing whereas the V1 is phased as part of the mechanical set-up.

Good to know for future reference. I've purchased a RJX head becase it works well and I have one on my Sport.
While I have you experts in one place humor me with another question:
In the past I've always made a CF tail control rod for my heli's - they provide better control and last longer than the stock rod.

Has anyone tried mounting a CF rod on the Pro when the servo is in the stock mounting position (ie: inside the frames) ? It looks like I may have to put the ball on the bottom of the servo wheel. The servo is a JR 3500G
Thanks

I'd like to know what the difference is between the Metal Main Shaft Bearing Blocks:

H45027

H45027A

I need some new blocks so it'll be good to know which is the best option for my V1.

Just use the V1 block with Ceramics or ABEC3/ABEC5 bearings. The actual holder isn't going to affect anything.

My bearing blocks came borked from the factory, I need new ones since they drilled the servo mount holes slightly off meaning they sit slightly slanted.
