mb it will break less due to the size and less mechanic parts.. but i also see helimax going the cheap route, tail case is less complex and requier less material, 2 bearing in less, 1 carbon shaft in less, 2 gear in less.. and finaly a smaller prop(less material).. all that should bring the cost of their tail to almost nothing.. :P personaly.. i dont like the look of that small prop on the tail.

saw the axe cpv3 on towerhobbies and the whole bell-hiller conversion will cost something around 9$ thats pretty cheap

the n60 will cost 3-4$ ?? hum
