I get 2100 at low end and 13000 tuned down to 12,400 for high end with my 46AX. You shouldn't need any more RPM than that.
State your prop size else you're post is useless.
I spin a 11x6 prop on my 46and it's 2800 or so at idle and about 12,200 at full open. this is a LOT of power for my 4*40..

Is there a link that lists RPM ranges for certain props? I have a APC 12x4 on it right now. Ive been trying to tune it and with my digital tach Im getting about 12700 at full throttle, should I be able to tune it higher?
Don't make things more complicated than they need to be. Tune by ear or Tach but the method is the same.
open throttle, and start leaning out the engine till it peaks and starts to drop off in rpm. This is a VERY noticeable change and you just can't miss it when it drops rpm, now you want to go back to the peak again and then richen the needle 3-4 clicks from peak.
now let it idle for a while, if it loads up and dies, lean the low speed neddle 1/8th turn and let it idle. now, increase the throttle (after it's been idling) and you should get VERY VERY little to no hiccups. if so, lean out the LSN a little more. Now go back and recheck our High speed needle settings.
I've tuned a few engines at my club (been tuning RC Car engines for a while and you guys in that hobby know ho tricky those can be). OS 46AX is a breeze to tune and it stays that way. I think it's pretty much THE set it and forget it engine.
