**WARNING** The larger bottom gear is fine now but my top gear just started slipping. The top gear is two pieces (inner and outer) the inner part is fine but the outer (teethed) part is slipping on the inner part. **-WARNING**-

This issue has been adressed. The gear will no longer slip on the pinion. The pinion is now splined and the gear will not slip. Good work HK. They listen to these comments.

I just assembled the HK450 (but no motor yet) and checked for this problem by trying to rotate the tail while holding the main rotor. Applied enough pressure for the teeth on the gear to skip, but no slippage. Perhaps this part has been fixed?

Just go buy the align part for $9 not worth trying to glue it, my heli went down twice due to this fault. This is the only weak part of the kit but unfortunately can bring your bird down instantly.

To solve the tail drive gear slip problem I did the following.

I drilled a 1mm hole in the base of the gear across the gear and shaft. After that I put a small pin, made of a small nail, in this hole fixing it with Loctite 601. Doing that is almost impossible that the gear will slip again. See a tutorial and some photos about this process at the following addresses:

Like many other bottom gear slipped just landing in grass. Luckily wasn't in flight as heli would have crash for sure.
Fixed it by drilling 1/16" hole through gear and 1/4 way into shaft* screwed in one of the extra screws* then cut off with dremel. Solid as rock at no cost.

	This is what happened, towards to end of 2 min video. Lucky I was hovering low. Give Po-Hong a point.

After putting the whole hk-450 together I almost crashed because the lower gear spins on the shaft, major pain to fix, beware of this problem or it could s**** your bird

The problem of the bottom drive gear getting loose is real and must be addressed during setup, otherwise you will regret it when you lose control of the heli anytime soon. Mine was fixed by filing the shaft a little on both sides and apply some epoxy before pushing the gear home.

The bottom gear of this part comes loose and spins on the shaft,resulting in no power to the tail rotors and consequently, no control over the Heli.Solution is:::remove black housing plastic,you only have to pull them apart,drill a small hole right through the gear and the shaft, and then pass some fuse wire a couple of times through the hole,wind the rest of the fuse wire round the bottom part of the gear and metal shaft ,secure with epoxy.

It's me again,I'm the one that told you how to fix the F016 part.You cannot put fuse wirw on the metal shaft, there is no room.Just feed the wire through the hole 2 or 3 times, wind round the bottom bit of the gear and secure with epoxy.

I have found this part to be weak as water. The bottom gear always spins loose after a couple of flights, and it is not a twisted tail belt causing friction, as it has been checked 100% I went and bought and original Align part and inserted it into the HK450 casing and no probs as yet. It is annoying changing this part, why cant they make it stronger?

Do yourself a favor and replace this part with the original Align part...I've had two of these parts fail on me, resulting in crashes.

poorly made. I ended up buying this part from another source - no more problem.

Do not use as is. Must be modified so the bottom gear wont slip. Hopefully this can be addressed by manufacturer.

This part has been rectified. The shaft now has splines and works perfectly. I bought two replacements last week. Infact if you look carefully you will see the splines in the picture. cheers and beers

Apresentou problema no 3� voo! Lenha! Align HB1013T-1 n�o serve como substituto. Procure por HB1013T-2 que possui 25 dentes na engrenagem!

Have to be careful, the gear can come loose. Easy enough to fix though with some heavy duty thread lock, and scratching up the shaft.

my original prt started slipping so I ordered 2 of these ... so far I have about 4 hours of air time on it and no problems yet ... I've already modified the second part, "just in case" ...
