From KAVAN RC Wiki

Elevator controls the model in the vertical axis; apply up elevator and your model’s nose will raise (and the model will climb if it has sufficient power), apply down elevator and your model will descend. Please note that your model can only climb if it has sufficient power applied. Your model will not necessarily climb simply because you have applied up elevator, and will normally need full power applied for a safe gentle climb. If the climb angle is too great, or the power applied insufficient, your model will lose flying speed until the minimum (stall) speed. At the stalling speed (when the airflow starts to break away from the upper surface of the wing), your model will start to feel as though it is not responding as normal to control inputs, and then drop with little warning – apply down elevator to regain flying speed and full normal control.
