Top Rotor Gear Slip

Hello all,

 

I have a S108g who's top rotor doesn't spin.  Upon disassembly it appears that large main shaft gear isn't engaging with the smaller drive gear - it's as if the main gear has slipped down the shaft - it can be pushed up to engage with the smaller gear, but the shaft naturally wants to slide back down and disengage the gears due to gravity.  I'm sorry if this doesn't make much sense, I'm new to these fun little machines so please bear with me.  Any help or advice is greatly appreciated!

My apologies if I missed a how-to elsewhere, I did search rather exhaustively before posting.

Hi Superova,

 

Thanks for the quick reply.  Unfortunately the gear won't budge up on the shaft - I've tried pliers with more than enough force to warp the shaft itself to no avail.  Sorry I missed your chat, I was away from the computer for a bit.

 

Cheers,

 

Alan

Degrease it then try a bit of Super glue.

That's odd. If it slipped down, it should be able to go back up easy. Try taking it off, and see if there's grooves worn in by the shaft, then try to line them up. If that doesn't help, let us know.

 

Is it just me, though, or is this the flavor of the month for repairs? We've had, in no particular order, a bad batch of bateries, a bad batch of gears, a bad batch of upper shaft connector thingamajigs, a bad batch of gears again, bad tail motors, bad recievers/transmitters, now the gears slipping.

You snuck under my post, and when I was trying to see the "1 new post" it just kept re-directing me back to where I was and I was getting all confuzzeled.
