FlySky FS-G7P Thumb System

Requirements:

• 1x M3 countersink ± 10 mm (lock ring)
• 2x M3 screws to adjust/reduce the default wheel angle of 35 degrees as required (Make sure the screws are nicely flat where they touch the angle bar)
• Needle file for finishing
• !Recalibrate after any change/screw angle bar adjustment! (as documented in the manual)

Features:

• Supports decrease of wheel default angle (35 degrees default)
• Supports thumb piece adjustability via lock ring as required
• Knurled surface for good grip
• Includes different designs with different sizes
• Includes a custom thumb lever for better usability (4 wheel steering, etc.)
• Base ring revolution dimensions are attached if you'd like to create your own thumb ring design

Why use thumb steering?

• One hand free to do any other task
• More relaxed driving experience once the muscle memory has adapted
• Catch your crawler when it falls.
• Put one hand in your pocket if it's cold outside.

How to:

• Use base wheel to support the ring system
• Print desired ring(s) as required
• Optional: Use custom thumb lever knob for better usability (the knob fits tighter than the original knob !Do NOT use force when attaching! Instead, use a needle file for finishing).
• Optional: Provide constructive feedback to improve the system

Printing:

• Base wheel does not need any support or brim (at least mine was working without)
• Ring 8 requires tree support for the small knob (Use brim for the rings if they move while printing)
• Thumb lever knob requires 45 degrees and tree support for decent results (see picture attached).
• I used "simple" hyper PLA

Finish:

• Make sure the ring on the main wheel has a nice finish to support the lock system as good as possible
• Use needle file to finish the lever knob BEFORE attachment using force

Final thoughts:

• The FlySky FS-G7P compared to FS-G11P (https://www.thingiverse.com/thing:7254058) was more difficult to create a comfortable thumb system because the wheel axle is further away from a comfortable thumb position
• Any increase of the thumb piece radius increases the thumb way, which we usually don't want, even if this system allows it to reduce the default 35 degree angle
• Reducing the default 35 degree angle too much might lead to a lack of steering sensitivity when using the wheel to steer (for example, in case of 4 wheel steering)
• I prefer the "*-_8_Final" version with a slightly reduced wheel angle via adjustment screws so the thumb can go the entire way as comfortably as possible while steering via wheel provides still sufficient sensitivity
