Overview
The MAD X4229 is an eVTOL airplane drone motor designed for high-efficiency propulsion. Long-shaft motors may be used to drive pusher propellers (motor located in the middle of the fuselage, transmitting power through an axle to the tail boom).
Key Features
- Energy efficient (230KV: efficiency >81%; 420KV: efficiency >80%).
- Recommended hover thrust: 2.5~4.0 kgf (230KV and 420KV).
- Optimized weight: 397 g (230KV and 420KV).
- Recommended ESC: MAD AMPX 80A (5-14S) (230KV and 420KV).

The above data are the theoretical values when the input voltage is 48V, for reference only. In the case of room temperature of 25°C and no additional cooling device, the current over 50A is non-working zone, 16-50A is short-term (about 10-30s), working zone, and below 16A is sustainable working zone. In actual use, please control the motor running time according to the working environment temperature and heat dissipation conditions.
