Hi all,

I am currently rebuilding my s4 t2 engine, but would like to know if I could use two "B" weight rotors? I was only able to get another B. I know that you can stay the same letter or one up or down. Is there any disadvantage or am I perfectly safe or I am going in the wrong direction with this build? Thanks guys!!!

 

Of course it is safe! It's most ideal to have the same weights, and that's what you have.
