Dl 50!!!
 

Hi Guys purchased a second hand motor with the plane had its second flight when I noticed oil coming out of the front bearing of the hub does that mean the bearing is on its way out no funny noises what could it be?

Front bearing is leaking. Nice thing though I'll bet that the bearings from a DL DLE and a DLA would all fit

yes its a DL 50 , never changed a front bearing on a petrol should I go and change all tge bearings if I change the front?

I don't think I would..... Depends on what I saw when I got there. You got anyone in the land down under that can replace them for you

You'd get more response by asking your question here:

Beginners don't usually use 50 cc gassers
