you will have to change the grips too to get the optimum servo resolution.
Helikraft do can do grips for the SE head or if you have some metal Raptor grips the arms from the Helikraft grips also fit the TT ones! Helikraft also do a swash follower to suit the raptor.
Ely.Q vision competition FBL grips also fit directly to the SE head with no modifications required!
I don't know if there is a fix for the Kasama grips or if another brand will fit so you would have to do some homework there!
At the end of the day I think you will better off just getting the new ThunderTiger FBL head as it is an all in one solution and even includes the mainshaft!https://rc.runryder.com/helicopter/t635658p1/
