I agree the material seems to be the issue. Anodizing also makes parts stronger...

We all use aircraft aluminum 6061-T6 for all of our applications. As suggestions from customers, we are getting new 7075 aluminum which is harder than the 6061 series and use these for the mixing arms and cyclic levers. We try our best to source best material for the parts.

I am not sure why you get the problems with most of our parts but we have had thousands of very happy customers out there.
I dont know Andy... Perhaps its the parts im choosing, perhaps its where im getting them from, perhaps you guys are using crap aluminum, i dont know. And to be honest i dont care anymore. I dont wish you any ill will and im not trying to cause you problems. I sure wish I could be one of your thousands of happy customers. I really do. But I have to say that i have never bought another product yet that has caused me as much headaches as your products have. I had a hiccup with an Align metal swash and i had a nightmare with the shogun tail gears but beyond that, from the 6 helis i own and all the parts i have had to buy to build them and fly them i can only say that i have strong negative feelings toward one brand or product. Yours. Its not personal and I think your pieces are beautiful. Its just that they should also work and although they are pretty enough to be displayed in a glass case in my study i would rather fly them. That is what you intended me to do with them after all. Right?

Ahwell... Lets just leave it. I wish you well and hope you sort out some of these issues you guys seem to be having. If you have an account with a carrier such as DHL, FEDEX, or the like and want this part for examination, send me a pm and i will give you an address where it can be picked up.

To the rest of my fellow heli addicts,

I didnt intend this to be a bash on MH thread. I may have come off that way. If their parts work for you im happy for you and jealous that i havent had any luck with them and you have. Let's try and understand that MH has a business to run and not get too out of hand with bashing them and hope that they listen to all the people who arent a member of their "happy thousands" club as im sure they will and do something about the issues some of us are having. The real intention of my post is to let them and you guys know there is a problem and even if its a one in a thousand problem "It's all fun and games till someone loses an eye" (reminds me of that old xmas movie 'You'll shoot your eye out, kid! haha).

Anyway......I know MH will get this sorted but im just not personally buying anything else from them until i hear many ppl saying "Ive had this MH part forever and i love it!". Its my own fault for being such an impulsive buyer i guess

yeah...
pretty much the same feelings here... and i too suffer from the impulisve side of the issue. i see something i want and buy it, trusting in it too easily. too impatient to wait for the reviews. MH is going to send me the 7075 mixing levers and washout arms, since my others got completely destroyed in a crash. i have the feeling these will be MUCH better, since my experience with alum has always told me 6061 is soft like tin foil, and 7075 was always rock hard more like steel. everything for my T-max that was 6061 broke in 1 day. everything that was 7075 i smashed into walls day after day and never even bent it. as for the tail pitch slider, oh well, chalk that up as a loss. but i'm still determined to make the mixers and washouts work, since me heli did fly REAL nice with those parts installed.

Chris T88, i too had a screw strip right out of the hole, on my V2 swash, was pulling a ball link off and instead of the ball link coming off the ball, the whole thing just yanked right out of the threaded hole. I found the screws used to be 'cut' off at the end, obviously to make them short enough not to stick out the other side and bind with the inner swash base, but this one was cut so short it did not go all the way through the swash hole to the other side, leaving very little screw surface contacted threads, thus the weak hold. replaced with a stock ball link screw, and a brass collar that is used on the stock mixing levers, it fit perfectly in the MH ball link, and screwed all the way to the end of the hole, thus creating a better hold.

I think you're confused. My issue is also bent mixing levers but when I tried to removed them (to take photos and post online) the head snapped off the screw holding them on. Now the rest of it is stuck in the flybar carrier...

I got the first version of MH tail rotor as well, but did not use it so far. I only replaced original washers by small steel washers I found in Align spare screw package.

Imagine, that after reading this thread, I am pretty much concerned about function of the MH tail rotor and safety of myself and people around, when I would go to fly with that upgrade part.

Fully agree with WRXRonald, that MH must take responsibility for possible safety issues which are discovered (like in other industry areas like cars) - in this case for rail rotor version one as well. Seems, that a kind of recall and replacement is needed...

Another option would be to have your 6061 parts hard coat anodized. It may even be stronger than the 7075 parts since the parts are so small. You can also hard coat 7075 but we have run into chipping problems when doing that, the hardcoat does not stick to the 7075 as well as the 6061.

You would have to enlarge some of the holes and the tight areas to allow for the 0.001" to 0.002" thickness of the hardcoat though.

Having your customers beta testing your products is not good business practice when you are charging them retail on the parts they are testing.
this comming from a t-rex owner made me laugh.

i think andy le has done everything possible here, he's offered a free replacement and he's paying for the return shipping (much more than most other companys do, i've never received return shipping costs on a faulty item return!) if you could find it within yourself to go to the post office, he's also stopped production of the part untill he can verify the problem. now do the rest of your fellow hobbyists a favour and send it back so andy can see if there is indeed a problem, as if there is indeed a problem it could happen to someone else with more serious consequences!

JonDoe,

Apples and oranges, Jon. Align's prices are 1/3 the price of micro-heli.

I have wanted to keep my mouth shut on this one. Im have to finally break my silence. I have also had nothing but bad luck with MicroHeli parts. I had a washout base fly apart in flight. How many times do these so called PRECISION CNC parts need to fail? Why was the locktite not added to the screws on my washout base? Why was AnnihilaT tail rotor flying apart. This seems to be a common theme among mH parts. If they are going to charge premium prices I expect a premium product. I personally will not test anymore of there items. I dont enjoy having to complain about mH parts failing in flight. This is serious stuff. They need to not only stop production of there failing parts but recall them all. Instruct there dealers to return what they have in stock. Whats more important money or safety of your customers? Im sickened over the amount of posts I have read about one thing after another bending and breaking. Its not about the money, who wants a mercedes that is in the shop every other week. Thats what this equates to. Imagine if your mercedes kept crashing because you paid a premium for upgrades on your car. Im pretty sure there would be some serious lawsuits in that situation. One of these days someone is going to have a part that is already known to have productuction problems fly off causing your heli to go out of control and seriously hurt a bystander or another pilot. I pray that day never happens. These are the facts and they are nothing to to dismiss as expected problems to just deal with.

One thing you don't see when you buy these aftermarket products is safe operating limits guidlines. What RPM do they test their products? I'm far from being an expert on the subject, but, all of these parts have safe operating limits to them, but, what are they? The companies don't say and maybe havent even tested what they are and furthermore, probably dont even care as long as they are making $$$. Just an observation from a neutral source.
