Aircraft Fit and Installation
Before installation, confirm motor dimensions, mounting compatibility, propeller clearance, and the aircraft's recommended power requirements. For a gas-to-electric conversion, account for the weight and placement of the motor, ESC, and batteries when setting the aircraft's center of gravity.
The 40cc-equivalent designation identifies a general power class. Aircraft suitability depends on model weight, flying style, and the selected electric power system.
ESC and Propeller Selection
SunnySky lists a 130A ESC recommendation and suggested propeller sizes of 21 × 10, 22 × 10, and 22 × 14 inches for the 190KV version. Select an ESC with a voltage rating appropriate for your battery system.
Propeller load varies with battery voltage and propeller design. Use the suggested sizes as starting points, then measure current draw with your actual setup. Provide adequate cooling and keep the motor, ESC, and battery within their operating limits. The listed 127A rating is limited to 30 seconds and should not be treated as a continuous operating rating.
