Im curious , do other guys have the same problem as me , no matter how much you tighten the rear boom block and insert that 4mm cap screw the boom still twists in the block in flight?

The hole elongates and the plastic key on the inside of the block wears down ?

you can always pin it.... but replacing the part will go along ways to fixing the problem

Never had that problem on my 600N or 700N. Are you sure that you are tightening it good enough?

After Afew crashes they do tend to come loose and need replacing .
You can put a wrap of tape on the booms before clamping which will help if your not going to renew the cases .

Yip,gets tightened propperly

Yes Tape also works well , but is painfull , You cant just , loosen and pull out , you need to remove entire block and to assemble boom , but it does work

Like Nick said,the newer boom blocks have the pre-drilled hole with screw to pin the boom...Its well worth it and it also keeps the boom from coming off during a crash..
The newer tail case is the same way....

yes, I have the new boom block ,but it is not long and that bolt wears the hole bigger in the boom and you get a twist

Are you sure your twist is in the front not the back. Almos all 600 and 700 i owned. The tail case and the body seem to have little clock wise twist. New or old.
