trouble with trex 250 fbl setup
I'm just getting back into the heli game. I'm totally lost with fbl system adjustments. I have a dx7s. I recently purchased the latest 250 kit. Came everything to build and fly the remote.

I followed directions for setup thoroughly. Three times, and I need you pros!

I not stop the travel which is pushing hard on the linkages. The instructions say to make the adjustments within the system. Its not working. The problem is mainly with aileron and elevator.

I am using only a satellite instead of a receiver and a satellite. I have even moved my servo horns and adjustedd the linkage just to get shorter travel. No luck their either.

Can someone send me a basic remote setup, and a 3d setup for the remote, and some thorough instructions to resolve the issue described?
I'm not extinct so why would my toys be?

Is this a 250 with a 3GX flybarless controller?-----

Did you get the Bind and Fly as in the video of a kit you have to build and setup yourself?

You probably won't want to hear this but the 3GX FBL controller was never a very popular FBL unit. I am not saying you can't get it to work but you may want to cut your losses and get a more straightforward FBL unit.

Since you have a Spektrum TX, a logical choice is the AR7200BX. It is both a Receiver and BeastX FBL in one package. It has been extremely popular for a number of years and well known for its simplistic setup. All FBL units have some learning curve but BeastX is about as simple as they get. Plus, the manual is well written.

If you want to persevere with the 3GX, your best bet would be to find some setup videos that go through a full setup.

The 3GX unit IS a straightforward FBL controller. It is very easy to install and to set up. Version 5.0 software makes it quite nice to use as well. I have ten installed at present, earlier this year was up to an even dozen, till I replaced two with GPros.

"Popularity" is often political. Many detractors had early problems, most of which I believe are directly traceable to not having an adequate source of power, voltage AND current-wise.

The OP is not having trouble with the unit itself, I believe he may not be all that familiar with FBL in general, and/or his DX9. I've been supplying help most of the day, and I think he is getting there.

Having set up BOTH AR7200BX and 3GX systems, I have to say the 3GX, by far is the simpler of the two. Nearly ALL of the setup for the 3GX is nothing more than knowing how to properly perform a mechanical setup on a helicopter to achieve what most have come to regard as a "3D setup". Swash and servos centered at neutral and mid collective with zero degrees pitch. Set up overall collective pitch, and set cyclic at an 8 degree reference -- that's it. Once you get the mechanical stuff out of the way, the actual 3GX "setup" is nothing more than pushing a button and moving a control stick to one end and returning to neutral a few times.

Rudder gyro setup is simple, nothing more than a standard Heading Hold Gyro procedure. Calibrating the pitch/throttle is also simple.

Once you've got the mechanical stuff out of the way in "DIR" mode, the rest of the setup takes less than five minutes.

Ron Lund has some excellent setup videos for the 3GX linked on his site, and the Jeff Fassbinder videos are also good.

The worst part about the 3GX is the manual. The unit itself is well-behaved. The 3GX tames the little 250 instantly and makes it a fun little heli to zip around with.
