Ok I am curious to know if this is possible and also what is needed. I'm only curious about this because of parts availability for the Expert mainly the rotor head...Is it possible for me to convert to an extreme rotor head only?

And no, I do not want to upgrade to a 90 at this point in time, I currently do not need the power and plus I'm happy with my 70...

I had experts with extreme heads with OS70 not a lot of power but if your happy with that kind of power then the extreme head just gives you better feel.

I am running a OS 70 in my stratus using 8.66 gearing and so far i am happy with it . As far as the head goes dont you have a metal head already? if so the only difference is the cliped head axle for the extreme and the extreme had a longer main shaft and an extra bearing below the maingear.
