Purchased the GM 14-7 to replace a Aeronaut 14-6. Bench tests show a slight increase in thrust and a two amp lower draw. Non-scientific flight tests with a recording variometer indicates a better climb. They fold very flat against the fuselage.

Good prop.Light and pretty design. Mounted on an SK3 35-58 840 Kv, on a Graphite 2 El.
Pulls 36 A on 3S, 425 W...PErhaps in a future, i'll buy an 15*8 for this same model.
In comparison with an 14 *8 Aeronaut, the 14*7 GM same tarcts the model, but with less current.
Unfortunetaly, there is actually no current measures for this prop, or other GM props.
