What to do if the BNF Blade MCP X BL Toy helicopter will not spool up?
- GGwendolyn RiosAug 16, 2025
If your BNF Toy helicopter won't spool up, it could be due to throttle hold being active. Turn off HOLD with the throttle low and trim centered or low. Another possible reason is low battery voltage. In this case, fully recharge the flight battery.
