HK-250GT Ball Bearing 7 x 3.5 x 2.5mm is good partsNo as good as align but who cares with this price!Who will complain if the price is that cheap?
Original ones (HK-250GT) were absolutely crap; broke one when mounting the heli (without spooling up the motor). These ones look better, hope they are.Most disappointed, I bought eight of these thinking that they would be metal sealed with grease inside. Turns out they have taken the picture from behind so that it looks as if they are sealed up, but the other side is open. So these are NOT a replacement for the 74zzd3 (because they would have been SEALED then). Not recommended unless you are such a frequent crasher that the longevity of the bearings don't matter anyway... :-)Make sure you have these as spares!Nice balls A plusplusplusplus plusplusplusplusplusplusplusplusplusplusplusplusplusplusplusplusplusplusplusplusplusplusplusplusplusplusplusplusplusplusplusplusplusplusplusplusplusplusplusplusplusplusplusplusplusEinfach ein gutes Preis -Leistungsverhltnis bei diesen Lagernthanks hk just what i needednunca tienen que faltar en la caja de herramientasMain shaft bearings for HK250GT!
