Overview
The T-Motor AT30A is an ESC (electronic speed controller) designed for fixed-wing RC aircraft. It supports 2-3S LiPo batteries and provides programmable settings via audible tone (“beep”) prompts and throttle-stick input.
Key Features
- Supports 2-3S LiPo battery use.
- Tone-based programming with 8 selectable menu items.
- Adjustable operating parameters: brake, battery type, cutoff mode, cutoff threshold, start mode, and timing.
- “Set all to default” option and multiple ways to exit program mode.

Manuals
Select programmable items (tone sequence)
After entering program mode, 8 tones repeat in a loop. Move the throttle stick to bottom within 3 seconds after the desired tone to select that item:
- 1. “beep” = brake (1 short tone)
- 2. “beep-beep” = battery type (2 short tone)
- 3. “beep-beep-beep” = cutoff mode (3 short tone)
- 4. “beep-beep-beep-beep” = cutoff threshold (4 short tone)
- 5. “beep-----” = startup mode (1 long tone)
- 6. “beep-----beep-” = timing (1 long 1 short)
- 7. “beep-----beep-beep-” = set all to default (1 long 2 short)
- 8. “beep-----beep-----” = exit (2 long tone)
Note: 1 long “beep-----” = 5 short “beep-”. In “Select Settings,” a long and short “beep-beep-” indicates the 6th option, and so on.
Set item value (programmable value)
Several tones repeat in a loop. Set the value that matches the tone by moving the throttle stick to top when the tone is heard. A special tone “1515” indicates the value is set and saved.
Keeping the throttle stick at top returns to item selection (Step 2) to choose other items. Moving the stick to bottom within 2 seconds exits program mode directly.
| Item | “beep-” (1 short tone) | “beep-beep-” (2 short tones) | “beep-beep-beep” (3 short tones) |
| Brake | Off | On | |
| Battery type | Lipo | NiMH | |
| Cutoff mode | Soft-Cut | Cut-Off | |
| Cutoff threshold | Low | Medium | High |
| Start mode | Normal | Soft | Super soft |
| Timing | Low | Medium | High |
Exit program mode
There are 2 ways to exit program mode:
- In Step 3, after the special tone “1515”, move the throttle stick to the bottom position within 2 seconds.
- In Step 2, after tone “beep-----beep-----” (item #8), move the throttle stick to bottom within 3 seconds.
