I just cant get my trex to hover in one spot and stay. I've tried the EXP's from -30 to -50 even. Eveything is great on it; the rotor is stable, no wag. It feels like it just over steers after I have stopped moving the sticks even. Its anoying! Like a kid that just cant stop moving and wont sit down.

You could have something binding or slop somewhere. I found with my Trex it was easier to hover with the Tx set around 0 EXP on low DR and +15 on high DR.

Hovering in one spot
I thought I had that problem once. As it turned out, the heli was stationary. I was the one swaying about...

stock swash plate is pretty sloppy... i can tick toc the flybar back and fourth. Like if you grab the flybar paddle and turn it like a key. I'd say it can move 2mm up and down, and it looks like it originates from the swash bearing.

Take it up a little higher to get out of the ground effect. It should be cleaner air.

Just remember, hovering only takes slight stick inputs.

I had my friend come over and we set the EXP a lot less back to where its snappy. He hovered It like perfect. I guess I was just used to my smaller micros and putting the EXP to the negatives I was not used to yet.

thanks guys

I thought the same way, make it soft around center stick should make it easy to fly. WRONG! It just made it sluggish, by the time I reacted the machine was to far out of shape it had me by the short hairs. Basicly it was flying me. Now that I have the Tx turned up it snaps to it and become fun to fly.

All the ball links in the head is very important... it must be super slop free, and so with the blade grips. You need to isolate each part of the head and check it.

I can hoover my -trex 1 feet in front of me and CATCH it at the tail boom and hit throttle HOLD....

And im only using 5%expo.

If i got $, I will run my T-rex on 10s lithium.

The EXP number is negative on Futaba and positive on JP. Check that the negative number you stated is correct. I did it backward on my Trex inadvertently and it does make flying more exciting.

I reamed all the ball links out already spinning a ball in a cordless drill; snapping each endlink on it and spinning. worked great.

Well i've never messed with the EXPs ever in my life till this trex. My Hitec says 0% for normal and can go from -100% to 0 to +100% So its EXP range is 200 points lol. I had it at -45% all around only the tail was default.

It feels much better at -20%. But i need to experiment.

You can also trying to bump up your head speed at hover stick, this will give better hold. Just my 2 cents..
