Got two new 150x. Using DSM2 satellites on both. Wouldn't bind until updated firmware to 1.1.1. Get through APP setup and everything works in Attitude mode. Get Aqua light on GRS pulsing bright to dim for power on/ attitude mode. On both TX, switching to 3D mode gives a steadily flashing blue light, which the manual says is APP connected. We cannot get either one to initialize in 3D mode and the GRS blue light pulsing dim to bright for power on/3D mode. If you take off in attitude, then switch to 3D , bird is uncontrollable. Gyro essentially is not initialized in 3D mode. Any ideas or help? Not first time. Flew 600 intros and mild 3D before. Pretty proficient with programming controller for helis, but I think there might be a problem particular to the 7 and 7s.

Same with my 250 DFC PLUS 3Gx Mrs BTF

I tried with a DX6i and DSM2 on normal the collective seems to be unable to hold the pitch curve and wild on 3D then tried again with Futaba 14SG on FHSS. Marked improvement in normal mode with the Futaba but practically no pitch movement on 3D. Not flyable on 3D.

Is your gyro menu enabled, if yes disable it.
The gear channel controls the switch from attitude to 3D mode.
What is your gear channel settings?

Are you referring to the GrX unit or the 14 SG transmitter settings?

In the transmitter.
For Pitbullsean's issue: My thinking is that maybe the GRS unit isn't seeing the correct gear channel output to properly switch between Attitude and 3D modes.
For iyoy: The GRS and MRS are very different from each other.
Specific to your issue, what are your idle up throttle and pitch curve settings?

GrX MRS

Just the settings in the manual. Also the manual says to leave the transmitter in H1 90 degrees, not 120 eCCPM because the MRS is supposed to do the mixing. It will fly decently in normal mode (although still kinda 'delayed' as far as collective mid range stick feel is concerned) but in idle up 3D mode, the collective moves very minimally, not enough to sustain flight.

Iyoy your issue sounds like a pitch curve or throttle curve issue, but I can't be sure without seeing your transmitter settings.
