In V2 frame screws bag and V2 canopy screws bag, the M2 x 8 screws are swapped to M2 x 9 screws and M2 x 7
screws.
The purpose of changing screw length is to solve the stripped screws issue.
After adjusting the screws length, both the upper and lower screws are now 3mm deep into the aluminum standoff.
Before the adjustment, the lower screws were only 2mm deep, which could easily result in stripped screws
Attached are the detailed assembly guides of V1 and V2.
Note: for F154 O4pro and Vista toothpick users, you should follow V2 assembly instructions when both the frame screw
bags and canopy screw bag are V2. If either screw pack is V1, you need to follow the V1 assembly instructions.
