Why does Immersion RC Rapidfire take a long time to lock?
- JJerry JohnsonAug 2, 2025
If your Immersion RC Rapidfire takes a long time to lock, and unlocks during short-range flights, and the video quality doesn’t seem right, it might be due to the flight controller. Some Chinese flight controllers with OSDs (MAX7456) use under-sized output capacitors, resulting in distorted video syncs. A known example is the Sunrise 30A 4-in-1. To confirm this, bypass the OSD and connect the camera directly to the vTx. For a permanent fix, replace ‘Cout + Csag’ with 47uF ceramic capacitors. Also, consider contacting your FC manufacturer to express your dissatisfaction.
