one way bearing slipping!
Hi All,
I just got my new Hurry 550 and have tried to have my first flight. It spun up nicely till mid stick on throttle, then it just seemed to loose all head speed as the pitch increased (although I could hear the motor screaming. I have removed the pinion with the one-way bearing and if I hold the teo gears in my hand I can make it slip if I apply a fair amount of force Has anyone else had this problem? Cheers Matthew Q |

no, there is a mod you can do, and if you look in the current rcheli mag they do a review on the h550. you need to remove the bearing and scuff up the walls of the hub it goes into, then either apply red or green loctite (prefered green) on the outer bearing race and press it back in. you can use ca too, but they recomend using green loctite, and red loctite if you have no green. then, according to rcheli mag your good to go.

feb issue. your right about if the bearing itsself was bad it has to be replaced, but, the way i took the tip from rcheli it made it sound like the slippage between the bearing and the hub would seem just like the bearing is bad. just take a look and verify the bearing itsself is slipping and not the hub around the bearing.

i had the same problem with a Revo and the locktite worked great. *** make sure you put it in the same way or else the bearing will "slip" the wrong way and won't spin up at all...it may look different from one end to the other, but make sure it goes back in the same way. |

Thank you everyone!
Hi All,
First post, thanks for the help! Hmmmm ... the mod might be to much of a pain, I have ordered another one but was curious to see if it had happened to anyone else. I have the whole unit out of the heli, I'm gonna check it now. Cheers from down under Matthew |

Loctite should never be used in contact with plastic. Metal to metal only. Many plastics will weakend and break or shatter after contact with Loctite.

so why does rcheli advocate using it in that spot? i know loctite will attack "most" thermoplastics, and i know absolutly jack about plastics. maybe it's (the gear) is not a thermoplastic. maybe delrin? all i do know is, if rcheli did it and nothing came of it, i'll do it too. although maybe i'll use thin ca instead...either way this is a problem that gaui needs to address.

if the kit was new you should try and get a replacement from the HS. it's amazing to me how much force these litte oneway bearing take and how important they are to the whole heli. |

Not sure which plastics get seriously damaged and which ones less so, and some that don't at all. But then again, how do you know exactly what plastic something is made of.
Better to use CA, epoxuy or other adhesives that are designed for plastic. I just tried searching the Loctite site, but nothing came up for use with plastics.

Also make sure the gear that goes around the bearing is not cracked between 2 teeth! I have had 4 of them crack on me and no amount of scuffing or locktite will solve it! It is VERY hard to see the crack too (it's a hair line crack) so inspect the gear really well.

Merry Xmas veryone!
OK the run down on what I found. The inner bearing and the outer gear are both metal, even though I had used green locktite the Hurry did her first two flights no issue (slow figure 8's and some fast acsents) However after close inspection I found the outer gear had slipped right down to the bottom of the bearing! The heli still flew fine but I decided to remove the gear again and used lots of red locktite. Now if has done an extra 3 flights no issue at all. I'm going to bring this to the Aussie importers attention. Not great for an "out of the box" experience, but I LOVED playing with it today. Matthew |

Which green Loctite did you use?
638 is probably the best for this.
