Hola Eduardo, cualquiera de estos motores cumpliría tus exigencias excepto el asunto de tu "chinofobia", porque los Feigao son de origen chino aunque tienen fama de buena calidad, además hoy día hasta los de las principales marcas en su mayoría son Made in China.
Como no dices que batería usarías, he supuesto una lipo de 2S.
Los resultados teóricos para una Zagi 400 con una APC 5x5 que arroja el Motocalc son estos:
