Hi Freaks I don't normally post on the Thunder Tiger section I'm an Align man myself but I was just wondering if any of you guys have run into this problem ? I will explain

I have been setting up a Mini Titan my brother has been given (yes given :shock: jammy ba$tard) it is used but not abused. Anyway to cut a long story short I spooled the heli up with it tethered down to check the tracking but after about 30 seconds the tail rotor stopped rotating but the main rotor still howling away :roll: Mmmm very odd and no stripped teeth.

Upon closer inspection it appears the small gear on the tail drive is spinning on the shaft it looks like it should have a pin or screw in there ? the gear itself has also dropped a few mm so it is resting on the main drive gear. I don't really want to strip it down now I have it all setup.

Can any of you TT Titan experts out there shed any light on this and if so do you have a quick fix ? or is it buy a new drive shaft ??:arggg:

I suppose the only saving grace is that this didn't happen mid flight :YeaBaby:

Many thanks in advance

Cheers
Glenn

That one was new to me. I would guess either it is a faulty unit or something in the tail has binded up pretty good (bearing?). Anyway, good opportunity to get the all metal tail shaft :-)

Mine broke do to a rececent crash. Buy a new one (pv0815) it has a brass gear and is only a few dollars more and stock. $14.29 at heli proz.

Thanks for the replies guys.

It looks like the pin that fixed the plastic gear to the bottom of the shaft has come out it certainly looks like a weak point and I cant believe its not a common fault, there is nothing there though it has worked loose and not sheared like I suspected. No seized bearings either

The pin size is tiny about 0.5mm in diameter I may be able to do a temporary fix with a needle and bond it in but I think going for the metal upgrade PV0815 is a good idea though. Thanks

Cheers
