Oil and Grease for electric helis.

No grease on heli's its a big drag on components, if you feel you must lube use a little sewing machine oil in a syringe. A few reasons there is not much info on lube especially if your a newb are.....as you may most likely crash before your heli has any hours on it you replace the bearings anyway (especially main shaft), the more you oil the more dirt will be attracted to said oil (remember its a big fan those blades on top), most bearings in a RC Heli are a "shielded" type....NOT sealed so they normally have a moly type grease in them or are ceramic so any lube you put in will find its way out anyway. In a nut shell by the time your heli bearings actually need lube you will have either crashed and replaced many or have well and truly got over the need to fly them and left them on the shelf Lock tight is not nearly as important on electric as it is nitro, use low strength or you will need to heat everything to remove/replace.

PS. remember cheap bearings growl even when new so no amount of slippery dip will fix it

One word of warning - de-greasing is possible, but it's equally possible that the replacement grease doesn't get where it's supposed to go.

A case in point - back when VCRs were a 'luxury' item, we got one for repair where someone had done just that - result was all seven motors seized solid and the thing was a write-off
