Are you notiding slugish response from your OS 46FX and 12.25x3.75 prop? I'm running 20% YS Powermaster, It kinda has to "spool up" to get to the high rpms. A real bummer, I've been using a Zinger 12x4 wood prop, it had instant response. I think the APC has more thrust though!
With the slugish response, I cant do my picnic table 2' takeoffs!
What do you guys think?
