    Problem with Driveshaft pins backing out

    hey guys,
    the pins of my driveshafts backing out after 1-2 runs. I use blue loctite on the grub screws that hold the pins in place.

    any ideas?

    THX.

    Are you using the right pins? The correct pins should have a groove in the center for the grub screws to seat into. Have you tried using 2 grub screws .

    Yes the Pins are Stock with the groove. Also tried using two grub screws. Same issue still.

    Should I try red loctite instead of blue?

    Just a thought but maybe you could try mixing the red and blue. Make sure you clean off any grease or oil before applying and let it set 24 hrs before lubing and installing.

    you probably have water in your foams causing excessive wobble or vibration. clean the grubs really good and let the locktite cure over night, put some on the threads of the mating surface aswell with a toothpick. I have yet to have one back out and do I bash the pig!!. make sure your not scared to tighten them or have your dad tighten it for you. worst case is that the holes which the grubs screw in are egged and may need replacing. clean them well,let the loctite cure, and all should be well. maybe a spot of superglue on the threads if all else fails.

    So, I've been allocated more dumb questions this month.

    DQ #49: What kind of differences are there between super glue & red loctite?

    Curious since I used both on battery tray bolts & they broke loose with about the same amount of pressure.
    Does the super glue adhere to pieces differently?

    I'm not in any way a chemist but if you have experience from other glues that work equally well I don't see any reason for buying Loctite. But again, I have no idea if Loctite has some special resistance against water, lubricants or other elements that our RC darlings are subject to.
