O.S. 71703507 - Needle-B (Groove) for Inflight/Remote R/C Needle Set
This spare Needle-B fits the O.S. remote/inflight R/C needle set.Notes:
- This is the optional Needle-B (identified by the groove on the head) that gives you a more unsensitive adjustement (less angle on the taper) compared to the standard Needle-A that is pre-installed in the inflight/remote R/C needle set from the factory.
- If you want a more responsive fuel adjustement, use the Needle-A (more/steeper angle on the taper).
