I had a major crash with my Hawk Pro today -- lost all tail control. Discovered the set screw on the tail rotor output gear had backed itself out -- no loctite on it at all -- and so the tail rotor output gear was just spinning on the tail drive output shaft. Of course this was inside the frames that Century put together at the factory. What are the chances Century will send me a new Hawk if I complain? Paul Meyer

Your chances are pretty much slim and none. You should have done a full teardown, I know you have heard before never to trust pre-assembled heli's, right? As you found out, all it takes is one missing drop of loctite to take you out.

I say why not try. You have a 50-50 chance of getting something at least.

I guess Ray is right, they might send you some parts at least, what do you have to lose?

If you knew about these forum to cry about your misfortune....then you knew about the need to take apart and check. It is talked about here and about EVERY other forum daily. I do not feel bad for you. Unfortunatly they will probably help you out....but in the end it will raise the price of kits or parts...so it is us that end up paying for your mistake.

Stepping off soap box now.

It's OK....It's not your fault !!!

I have always wondered why people buy ARF heli's when they have to take them apart anyway. I suppose sometimes you don't have a choice if that is the only way they are sold, but other than that, why?

Ok, I want to know how many people actually pull apart a brand new heli to recheck all the screws and bolts. I'm not saying that it's not a good idea, but I just want to know how many people actually really do it?

Hey,

I'm sorry to hear of your crash, especially in the circumstances which lead to it.

However as has been mentioned here I doubt Century will honour any claim as I am sure there is a statement in the instructions which says to check all major assemblys/pre-built sub-assemblys for loctite.
There is obviously no harm in trying and maybe they might help out with shipping costs etc. to soften the blow.

In reality I am sure you will find most if not everyone who buys a new, ready built heli will atleast take apart the major areas of said model to check for proper building steps. In the case of my own Hawk, while I wanted to fly the model as it came the instructions do state to check all the pre-built assembles & add loctitie accordingly. In my case I just took apart the major areas, main rotor head, tail rotor, main frames/shaft etc. and went from there.

I will highlight this thread to the powers that be in Century and see what happens from there.

Anyone that wants it to stay in one piece and fly right will. I have seen all kinds of stuff, missing screws, no loctite, thrust bearings in backwards, you name it.

My first hawk had no set screws to keep the pins in place that lock the nylon gears nor is it shown anywhere in the instruction manual.

If it weren't for the info here on RR my heli would have been buried along time ago.

One lesson my hawk has taught me and that is to tear it down after every 10-15 flights or so to check for worn out parts thats how I found out about the tail and the intermediate shaft, I also found worn out ball links and loosened bolts.

It's like flying an old Harley !

I also pulled the backplate off the engine to add a little bit of gear oil every 20 flights or so. My 37 Is still in near mint condition.

I would recomend to anyone if you want your engine to last to add some gear oil to their engine bearings once in awhile.
This type of oil works very well on the other bearings too.

just 2 more cents worth

That the stuff.
Don't put a big glob of it. Just add enough to coat the bearing.
check it after a 3-4 gallons to maybe add more.

If people did this with their OS 50 Hyper to start with I'd bet there would have been less bitching about the bearings.

just 2 cents more

Sorry
Not in the manual for the Hawk Pro

What it does say however is

"Greatly facilitating assembly. Various assemblies have been pre-assembled, Only requiring the final assembly and installation of the various sub-assemblies.

Personally i think it should have some kind of notice saying to strip it down and where and when to use locktite,CA/Epoxy etc

Just learn from mistakes. You ALWAYS check the whole heli from top to bottom, front to back and make sure every piece is correct and locktited, ca,ed ect. Not worth it to take a chance.

Hey SeaKing,

I think there is a seperate printed sheet or notice from memory, I know there is one with the Swift for instance and I'm sure CenturyUK bundle the same thing with their Hawks. Of course it is possible a kit or 2 could slip out the door without said sheet.

Next time I chat to CenturyUK I will ask this question.

I've got 9 hawks and 2 Predators
None of them have ever had a seperate bit of paper relating to this

Some have had however a seperate bit of paper with a kit Number on it and who checked/Packed it 4 of the 9 did at least

Hey Roger,

Ah, as I said I know it's in the Swift kits now & thought it was the same with Hawks to but need to ask CenturyUK to be put straight.
The Hawk I have is their PRO 50 version but dont have the hard copy manual to even look at here.

As you say it's not in the manual looking at a copy online and could do with being added.
I will put the question to them to stop any future problems.
