Hey all 👋

I’m running a **Flycolor X-Cross HV3 160A BLHeli\_32 ESC** on **12 S** with a **Saite 6384 120 KV** motor and **Maytech MTSKR1905WF V3** remote.

The issue: the motor reaches **full RPM at only 25 % trigger travel** — anything beyond that does nothing.

I can’t connect to **BLHeliSuite32** (ESC powers up and beeps, but always “connection failed”), so I can’t adjust throttle endpoints there.

Has anyone fixed this just using **Maytech remote settings**?

- Is there a **throttle calibration mode** on the remote?
- Does the **HV3** auto-calibrate throttle if powered while holding full trigger?

Any help from others running a **Maytech V3 + Flycolor HV3** combo would be awesome 🙏

Did you work this out? I have a question for you about wiring between the BEC (I have MatekSys) and Flycolor X-Cross and the Maytech Receiver . The BEC I have has 4 wires - 2 of them I’m pretty sure need to connect to the main battery +ve and ground to pull in the 10S volts … I think the third +ve wire goes the receiver to provide the 5v power … but I seem to have a spare ground - the receiver has a ground from the ESC already?
