On the build of Protos i could not get the tail to slide smoothly.
All goes well untill the "tail bell crank" goes on.
After a post for help i was told to inspect the bell crank.
On my kit part the "c arm" section with holds the partially threaded bolts were not on the same plan.So with 1 bolt installed the tail is sweet BUT install the second bolt and it binds.
A guy had success by bending/twisting,i tried this and it snapped.My fault so i ordered a new one.This came warpped/twisted/distorted/baddly moulded also, BUT the "c arms" were out the opposite way this time! So i thought it must be a hit and miss thing so ordered a second on.This came warpped like the first!!!
Just for the fun of it i ordered a third and guess what,PERFECT.Lovely smooth tail.
So out of 4 parts only 1 is up to the job.Ok,at £4 each its not the end of the world.
And i suppose someone will now say "take them back to vendor" But how many venders will want to open x amount packets.
Anyone want 2 warpped bell cranks??

Hi 600rr, I see your point. But take them to the vendor for refunding, If they won't change for free=bad vendor. I think Corrado and MSH would agree to that.
Good luck flying your Protos.

To be honest the shops i use do not want to know about things like that.
Another example is warpped Align main gears.Take them back and they say "thats normal" And to be fair,It is.You are lucky to get a nice true main gear.And i think its the same with the Bell crank.
They should not reach the shop/flyer inferior.Wheres the QC?

Defective tail parts
Good Day All,

I had the same issue with the 'C' pitch arm being tweaked however; I wasn't going to keep ordering the parts until I had a good one. I ordered a CNC-Tail assembly from Infinity and that fixed the issue for good.

This is the first Heli kit that I’ve built that doesn’t have thrust bearings in the tail but then again I’ve never built a non-Nitro kit, seems that the Protos tail bearings will wear quickly.

Yeah, but that´s Align man! The very reason why I moved to MSH!

On the tail grip bearings. I have had mine in place since the kit was released and have never changed them. They are still buttery smooth. I got one of the first batches of kits shipped in the USA. So 2 years?? I can't remember. As far as any other parts made by MSH... I have never had a problem with the quality on my Protos.

I even fly mine with the 1st. batch original tail parts, etc. Not hard 3D, but anyways it's holding up just fine

Tail bearings were never mentioned.Just the moulding of the tail bell crank.In my case out of 3 units,1 kit and 2 bought seperate ONLY 1 was straight/true to allow the partial threaded bolts to enter groove on the tail slider.
Looking at posts here since others have found the bell crank to cause binding.Fine with 1 bolt installed,no good with 2.
Just my case and no other parts been questioned.But QC must not be tiptop.

I had the same issue with my protos. The tail was silky smooth until the C part of the tail control was installed. What was really weird is when the vertical tail fin was tightened down, the tail smoothed out a little bit. I am not going to order 3 kits to get one that might or might not work. Poor quality for a very expensive bird.

The C clip is always "stiff" when first installed with the slider. 1 bolt is smooth, second one is stiff. Mine was the same way (original kit).

3 flights later, it was flawless and has had zero slop since.

IIRC, Corrado even acknowledged that its meant to be that way and expects it to be stiff initially, but it breaks in nicely.

You have to remember that this is plastic and you cannot always control how it cools like you can when CNC metal is machined.

I agree about bad quality of some parts.
I have 3 bad tail shaft pulleys. They all have lots of wobble. I have high frequency tail vibration because of them. I have ordered CNC pulley. Should help to fix the problem. I have read lots of posts about tail vibrations, usually people solve them by replacing whole tail plastic assembly with CNC tail assembly and CNC pulleys. I hate helis which requires upgrades to fly good.

Same problem here. C clip's ends are not aligned (tried two of them), because of that it damages MSH50095 part (it eats plastic wall of the groove for C clip's screws). I had to order CNC C clip to fix that.

Plastic cyclic servo mounts are joke too. If you do not want to break your servos in not too hard crash you must replace them with metal mounts.

I was really happy with the heli in the beginning. It feels very light and powerful. But now I am thinking about selling it and get proved Logo 400. I do not care about the weight if quality has so many flows.

I must disagree about the tail servo mounts. I would much rather break the $3 plastic mount than the case of the servo itself. Metal mounts are more likely to crack the servo case. The latest servo mounts are a bit beefier on that note though.

Not correct. Plastic mounts break servo cases, metal - dont. Do the research and you will find lots of photos with broken plastic mounts and broken servo cases.

I have never experienced it with the plastic mounts and was only expressing my opinion. I have broken 7 sets of plastic tail servo brackets. None of which broke my servo case. I'm sure it all depends on how you mount the servo as well.

It is not my crash, but it shows how plastic mounts break servos.

I don't doubt it happens. The picture you are showing is not a tail servo mount.

Sorry, I did not specify that I am talking about cyclic servo mounts. My bad. Plastic mounts work just fine for tail servo.

I am not going to argue with you...I think that you shoud ask about issues not about posts...

You mentioned the posts.

I see no argument here. Corrado simply asked you where the posts are. He monitors these forums quite diligently, dare I say more than many of the manufacturers out there.

There is obviously this thread that shows 8 possible people that have issues. If this is truly a widespread problem, Corrado most likely would like to see the posts so the problem can be corrected.

Getting to the heart of the problem requires research. The only way to do the research is to see the posts.
