Review by: Adrian Mahovics
I have bought this GM 14x7 prop as a replacement to my AeroNaut 13x8 on a Hacker A10-7L with 4.4:1 gearbox which is built into a Picares Langohr F5j model. It is absolutely amazing. It performs well and the fit is just so much better to the fuselage resulting in less drag while gliding. The only reason I gave 4stars and not 5 is the fact, that I would like to see some brass insert at the turning point of the folding prop blade as it is carbon only.. see how it will hold up. Neilís service was great as one would expect by looking at the positive reviews! :)

It is a wonderful product.
Although the current value fell, it became powerful.

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.
