Guys, on my new Arrow RTF, the Evolution engine manual that comes with it instructs you to set the throttle trim to the mid position

to give you 1mm of throttle open at idle. The JR 400 Tx manual instructions just say you want a 1/16 inch opening at low throttle,

stick all the way back, no mentioning of trim setting. This is my first fuel engine.

I have the 1mm or 1/16 inch opening BUT ONLY WITH FULL UP TRIM SETTING.

Are there any problems I can run into with the throttle trim on full up or should I adjust to mid?

Thanks!

Left photo is at mid trim (no opening at all)......middle photo is at full up trim..........right photo is full throttle and full up trim.
