Tracy,

Prop is a prince P tip, 70” dia by 90” pitch. Any suggestions as to what numbers I can alter to convert US gal. to litres? Somehow I have to get the readings up 3.75 to get litres. Neil.

ONLY? 6300 is at the HIGH end of normal static. I would be more concerned about over Reving at top speed if this were a 200+ MPH plane. It will probably be about right for the glastar though.

Be happy, celebrate! BTW, what are the numbers on that prop? L x P?

All,

Looks like I am finally connected after many attempts.. I have a P ported renesis in a glastar that is ready to fly. Tuning the motor yesterday to find that I cannot get the motor revs over 6300. I suspected the prop (prince fixed) is too big, but am assured that that is normal as a static load. Lonnie suggests that once moving the extra revs will appear. How do I tune the motor for the top end revs? Any advice? Neil.
