Default picco 28 factory needle settings?

Hello all,
I'm new to nitro, and bought a trinity 28, which is the same as picco... it came without any paperwork, and i'm wondering what needle settings to use to start break-in. Thanks for the help!

I guess this engine uses the same carburator of P7R-Evo2 off road

so the needle settings are

Master Needle 5 to 51/2 turns from closed
Low speed, needle out of ball end (rich side) in (lean side)
Idle 1/16th inch open

all according to instruction sheet

The engine comes with a default setting which must be a situation to fire it up.

Tiny adjustments may be needed to the idle screw en when started just find the right rich setting on the HSN for running in.
