just got a 90se
and noticed that the socket screw on the headblock
that goes into the main shaft (page 31 item no 1socket screw m4x20)
doesnt go all the wat through like the 90 std
im going to put a replacement socket screw in
a longer one so i can put a nylock nut on the other end (m4x25)or (m4x30)
which are the strongest socket screws to use
the ones that have threads all the way the shaft
or the ones with just threads at the end ?

thanks

Hello,
I actually have a fresh kit that I am building right now this is not an "early" kit problem. I know exactly what your talking about as I just ran into myself. From what I know the 90SE headblock is threaded but they supply the locknut for it anyway. Since it is threaded all you should need is some locktite on the 4x20 bolt with out the nut as this is what I did. Just make sure that it is tight.

As an option I have heard that people are using main rotor blade bolts for a Raptor 30/50V2 as replacements so that the supplied locknut can be used. Remember no loctite on the end of a screw with a locknut.

If you ask me it is complete stupid to include the locknut. I wonder how many people have been confused by this. You know how much money they would have saved by not including the locknut in every SE kit? It's the stupid things like this that frustrate people.
