Phoenix and TRex 450 - where's the gyro?

[th3tick]

I've got a TRex 450 with a GY401 on it. I've flown it for about four months now, and have a pretty good feel for it.

Just today, I got the Phoenix RC sim, downloaded the upgrade, and tried flying its TRex. The tail is constantly flopping all over the place. I've upped the gain, and I get genuine tail twitchies, but no better hold. It tends to windmill like crazy, or just shoot out 30-50 degrees for no reason.

Is there something I'm missing? Also, the tail is INSANELY SENSITIVE! I've put in a fair amount of negative expo, and it feels like it's either complete mush in the middle, or a tail for a propeller. There's no feel that's quite right.

Help!

TIA,
John

Hey, I've been using Phoenix with TRex 450 ALOT lately - but not getting these issues? I'm no expert but if you open the system >> your transmitter menu do the red bars move smoothly as you move your transmitter sticks?

Well, try this:

Fly tail-in out straight ahead about 100 yards. Then, keeping the tail still pointed at you, bring it back tail-in fast. On my real TRex 450, I have little tail management to do. On the sim, it windmills back towards me, and before it's half-way back, it's nose is pointed straight at me.

It really hurts my brain that the real gyro is better than the one in the sim.

From what you say it sounds like you have it set to Rate gyro mode - if you go into the edit aircraft menu under tail rotor tab, does it say rate or heading-hold? Or do you have disable heading-hold mapped to a switch and have it enabled?

Nevermind. I found it. That's the third control I've needed to reverse to get the setup right. You'd think after two others, I'd have thought of that for the gyro.

Reversing the "disable heading hold" channel did it. In all, for the default DX7 setup, I had to reverse 5, 6, and 7 to get it right.

Now, it flies MUCH more like the real thing. HOORAY for gyros!

And thanks for the help.
