The Rush ec fuselage is from us , the fan tail is made in plastic that very same the hirobo and plastic case , it is very limited thin material and very little metal parts .but the cg is very diffcult to blance they are highly commend for 4s lipo /2300mah battery and 3800 kv .I have join their test fly in hk .It fly ok ! just upgrade the power set ! After sew this metal ring i don't belive offer good balance in the fly preformance ,if this version are motor tail that is more diffcult to balance !Anyway that is my personal commend
