If you where in normal mode when punched it then the tail is going to kick out. the head/tail speed wont be high enough. So even at full pitch the tail wouldnt grab enogh air right off the bat.
Hey guys as I said it is normal that the tail will kick and is a normal thing the trex will do no matter what the headspeed is. If he is using a 13T pinion then he is in the 2900-3045 rpm range. Trust me when I say this is normal. The only theing I have found to fix it is to counter balance the tail blades grips with weights. All you really have to do is to use a ball link on each grip. You use a longer blade bolt and push it through the ball links and through the grips. This really helps a lot, believe it or not.

I wouldn't say a kick is normal as mine doesn't kick now that I fly in idle up at 90% linear throttle on a medusa 28-32-2400. My friends heli doesn't kick either on a scorpion 2221-8 motor and he like to punch it. So maybe it is a align motor thing, setup, or throttle setting. They all could add to the issue.

jbolt - Just for fun put a linear 90% throttle curve in your radio for idle up. Fly the heli in idle up and try going full collective from a hover. You should have plenty of headspeed at this setting. If it kicks out then I would verify that you aren't giving any tail inputs inadvertently, and then look at your gyro (verify it is properly centered in rate mode for a consistent hover). Good Luck,
