    Сделано хорошо качество приемлемое . Баланс немного страдает но легко исправить с помощью нождачной бумаги Убрав немного с обратной стороны лопасти

    About 60% of gas(that is, below the stall) give the following result: Prop thrust (g) consumpt. Power (VxA) previous Prop 6x5 750 229W 3.8g / W (original was on ME-163 by hackers) Gemfan 6x6 HiSP 650 304W 2.1g / W Gemfan 5,5x4,3 HiSP 520 228W 3.3g / W Gemfan stand.6x4 700 226W 3.1 g / W So with the same power as the previous Prop, the privious prop brings 80% more thrust than the Gemfan 6x6 !!!! Even the normal Gemfan-Prop 6x4 (instead of 6x5 Hacker) takes about the same amount of power as the former prop, but 8% less thrust.

    Poco hay que decir de la calidad y la fiabilidad de una hélice Gemfan. Para mi son de lo mejorcito del mercado. Las utilizo desde hace años tanto para aviones como para multicópteros y de momento todos los modelos que he probado de Gemfan has sido buenos. Eso si, hay que balancearlas antes de usarlas porque lo necesitan. Pero por el precio que tienen, y encima te vienen 2, qué más se puede pedir. Recomendable 100%
