RE: Axial .28?
Tower will stock the Axial engine parts soon. They already have the front bearing listed on their site [link=http://www2.towerhobbies.com/cgi-bin/wti0001p?&I=LXPEA3&P=7]HERE[/link]
It's the same front bearing that's used in the HPI .28s and the RE Surefire .32(and probably more), so getting them shouldn't be a problem.
