Msrx with msr microheli main rotor hub?
 

Hi all, I've just picked up a second hand msrx. It flys ok
But I have noticed that the main rotor hub by microheli is the
Msr version with the little top piece where as the msrx version
Is different it is flat on the top.
Two questions, will this perform as well as the msrx version? And
also, will the msrx microheli blade grip fit with the msr microheli
Main hub? I am concerned that there will not be enough clearance
Where the hub is different.
