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.

My problem with the sim is best demonstrated via:

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.

Help!

TIA,
John

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 right.

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

I really hate the way the the 450 flies in the newest version compared to the previous version..I may just go back to the previous update because I liked the way everything flew a lot better..Dont like the sound of the blades either..The crash updates are nice though..

I hear ya about the blade sound. On my system, hard movements make it sound like a woodpecker is in the area.

I can't speak about the old version. This isn't bad compared to the real thing. I need to poke around and see if there are other bodies you can strap on the thing. Not a big fan of all-white with a few stickers.

My son likes to crash it over and over again to see the new crash stuff. I was showing it to him over and over, then realized I didn't want to be training my fingers to do that!

i use it for the 450se too.

I find many things wrong

Loops and rolls are WAY too easy on the sim.. just bank and it rolls.
