Cualquiera de estos dos es supervalido, y el precio no diras que no es barato, ademas pillate este UBEC y esta LiPo y a correr:

En cuanto al Gyro, yo tengo claro que es mas barato comprar uno bueno que comprar uno malo para luego acabar comprando uno bueno, asi que lo suyo es pillar un Futaba GY401 + Servo Futaba 9254 una opcion seria buscarlo de segunda mano.

Una opcion barata seria esta (aunque desconozco el funcionamiento del Gyro, del servo siempre he leido cosas buenas):
