t rex 600pro

[agh321]

hi just rebuilding my 600 pro after a nose in auto (oops)
and was wondering if the metal mast bearing blocks are a good upgrade
and worthwhile doing
the plastic ones are ok but ive had it in my mind to change them for a while
and while ime re building i could do the upgrade

do they make the helie any better??????
