e-HeliDirect HDX 300-600 > 300 tail pitch

So I rebuilt my little 300 today and now it wont turn clock wise (tail in). I uped the throttle curve a bunch to see if that was it, nope.
messed with the gyro and TX gain, nope. Looking at this thing it seems to have a ton more pitch the opposite way? the direction it doesn't need pitch to turn. WTF? What am I doing wrong? Almost seems like I should switch the rotation of the tail. Now the tail turns counter clockwise, up into the main rotor. Is this little guy suposto turn the other way? It flew fine before the crash/rebuild.
Thanks

Hey your belt is probabley twisted the wrong way. Take it apart again and twist the belt the opposite way it is now.

Your tail rotation is correct, turning up into the main rotor wash. They sure can be sensitive little buggers in regard to pitch settings.

Got my 300 flying again... YEAH!.. After flying the EVO 90 this thing feels tame! I'm thinking about putting the e flight brush less 5400k in place of the stock out runner? any thoughts? Throttle curve ideas?

What head speeds are you guys running on these little guys?
Thanks so much!

No question about it, my T-Rex 450SE is my largest, and best flying electric heli. But having said that, I still fly my HDX300 more than any of my five helis. I think it's a combination of being stubborn and the challenge of making it work as best it could.

As a matter of fact, it has so many home-made or modified/swapped in parts on it now that at home I call it Frankenheli. I've become very comfortable with it and have solved most, if not all issues I had with the heli.

It's funny in a way. I built my 'Rex strictly to the instructions, bought a ton of spares (thinking of how many times I crashed my Blade CP), and started flying. In over a year of flying the 'Rex, hundreds of flights, I've had NO crashes and only had to replace the main gear (lost some teeth!). I have almost enough 'Rex spares to open a hobby shop.

My HDX300 has had just about every part replaced multiple times. A lot of parts, including the frames, were modified. It is currently a reliable little heli. My worst crash saw the almost total destruction of the heli and it never even left the floor. There was a lot of rebuilding and modifications after that crash, but I ended up with an even better flying little heli.
