    Re: SEAPLANE TENDER STAND ADDITION
    Re- Bouncing off jettys broken mast and now drip trays to catch oil Hi Martin, I use oil as the bearings need constant lubrication at high speed and I don't trust Chinese bearings to run without it. The shaft clearance is pretty poor in the inner Diam which I think is where most of the oil is leaking (have the same thing with the Graupner bushed shafts in the HSL. Grease tends to get thrown off shafts and does not get through such small shielded bearings. Probably ok if you have a high pressure grease nipple on the shaft tube. In all electric R/C aircraft the usual thing to do is remove the motor now and again and use a special thin oil in the bearings (Scorpion sell their own oil for this). I have pulled a few dud bearings from motors apart, and there has been no trace of grease even though the motors have been near new. They are very small bearings, so will get hot rapidly without regular lubrication, and seeing they have metal shields, there is no way of getting grease in anyhow (without perhaps using the motorbike chain 'cook in grease' method which would not be practical) The
    shaft oiler devices
    are made to suit lost oil replacement also. The weeping oil also calms the lake water and gives it that used smell and authentic look, and stops the ducks legs squeaking as well πŸ˜ŠπŸ˜€πŸ˜‚ JB
