I know who set this plane up and we always use fixed end points but I will double check when I get into the ESC.

<div dir="ltr">Sounds like a Castle ESC in "Auto" endpoint mode. The correct way to handle one of those is to arm at FULL throttle and then drop to zero throttle, that way the ESC knows the high + low end points. If you arm at low then it "guesses" at the top end point in the first few seconds after it gets a signal above zero, hence a slow advance of the throttle confuses it. (Castles are designed for sport fliers who think a takeoff is full throttle immediately). <div>
<br></div><div>Personally, I *hate* the idea of arming a system at full throttle, so with a castle ESC (I think I'm down to 1 of those in my hangar at this point) I set up fixed end points right away.</div><div><br></div>

Hi guys,</div>

<br></div><div class="gmail_default" style="font-family:'comic sans ms',sans-serif;color:rgb(0,0,255)">I need a little help. My buddy has just recently bought a Mythos 125 and has gotten frustrated with it.

He recently went to this motor so that he could fly 8S packs which he is currently running. </div>

Before I dive into it (which I haven't yet) by looking at the logging on the ESC, etc., is there anything wrong with this combination? I've always flown Castle ESCs myself but I remember reading on here not too long ago about how the Q80 and the Castle controller don't really get along. I mainly want to make sure that this doesn't apply to this combination as well. </div>

Essentially, if you start at idle and bring the throttle up slowly as if you were in the air flying transitioning from a down line to horizontal, the RPMs only increase slightly even to full throttle. Two takeoffs were aborted due to this. If you jam the throttle from idle to full throttle, the motor comes alive and performance is spectacular and it will act fine with smooth transitions for a period of time if not the rest of the flight.</div>
