View Full Version : What is breaking on the msr-x?

Really troubled about all this
Don't ask me how but I actually learned to fly this thing somehow without one hard crash
In fact the ONLY major crash I had was when I lost power
Momentarily to my tail
One blade grip
Understandable I suppose
This what troubles me
This thing is not cheap
I did no major damage or harm to it
Except with my clumsy thumbs on the skids
I waited between flights (about 100 maybe)
I should have kept records
Have no main motor and two weeks later I have no helicopter to fly
I see lots of people having this problem
I understand crash damage but losing my bird after just learning to fly it
It seems something is terribly wrong here
I expected better and was VERY careful and do not believe I did anything to cause this to happen
Thoughts on whether horizon should address this soon?????

-Grips (when stock), now MH
-Cracked canopy (no big deal, just taped)
-Swash balls / links. I've got a new swash on the way, but one of my long balls is worn enough that it will pop off in flight if i get really crazy with the cyclic. It started popping off on harder crashes...then softer crashes...and now anytime. I tried switching it to a set of new links and the helped for a little while but it is happening again. Can't wait for MH to get a shiny swash upg.

What's breaking with the mSRX?
My patience with ground based shipping. :P

I went to my LHS today to almost finish getting my MSRX parts dept stocked, i don't own a mainframe or a 4n1 board ( I hope i never need a board )
so i asked him if anyone else has bought motors from him, he said no one has called looking for one, or come in the store.
he recieved three in with his parts order and i was the only one to buy one.

First thing I "broke" was the tail rotor. I was surprised how quickly the mSRx lifted off, lost control and smacked the tail against the wall. With one side of the tail rotor bent, the heli acts really funny. It'll rev and cut the tail motor when I'm hovering, sounds like a seal barking. Finally decided to replace it and the heli flies smooth again.
Broke the ball off a blade grip today, I can see that's very common. The old mSR will have to stay grounded until I get some spares.

I just had a minor crash that resulted in the main motor sliding up and almost off of the frame; the glue's bond broke apparently. I have let it cool a bit between flights, so I doubt heat was the issue.

you don't think heat was the problem, that black goo is like 3 times harder than hot melt, and a bitch to get it off clean.

I will be hot gluing the motor tomorrow to see if that bond breaks, something just tells me that it was the force of a previous crash that jarred the motor is all.
Edit: I have had 2 crashes that were hard enough to shear ball joints on the rotor grips, I am not at all pointing to HH as the one to blame in this issue. While I know some have experienced tech problems, my MsR X has performed well beyond what I would have expected as a brand new pilot to an "intermediate" model.

BTW, the black stuff is silicon tub and tile adhesive e.g. DAP 08642.

Vakan, how did you figure out what the black adhesive was?
01-11-2012, 12:12 PM
from Horizon support. I should've said.

I use "GooP" as its a silicone adhesive thats clear, It comes in many varieties but it dont matter which one you get. Its much stronger than the stuff HH uses and yet will peel right off when you need it too.

I got mine at Christmas but it sat for a few days pending better batteries (My Turnigy 160 nano-techs are too old to hack it in the -X). Got about 15 flights before the tail motor went awol - twitching then dying. HH replaced that and since then nothing's broken. Then again, I'm still taking things easy on it and it's had no hard crashes.
One possible problem is looming. This might be my imagination but the main motor seems to get a bit tighter after a flight. I've put a drop of oil on the bearing and left it upside-down to run inwards, seems better. It doesn't get as hot now but the problem hasn't entirely gone. Anyone else have similar?

I had my first part failure today: broken ball joint on a rotor grip. I cut throttle before it hit the wall, but it hit the wall at just the right angle so that it took the brunt of the force.
I hope that's all that's busted. I'll hit the LHS to pick up new rotor grips (they have a bunch in stock, fortunately). The rotors will probably be replaced as well as a precaution as I notice that they are getting a bit loose even after tightening them down.
All in all, I've had just over 5 hours of solid flying time over the past three weeks with this little helicopter hitting the walls and dropping it to the floor and this is the first part failure (and by failure, I mean it gave way by duress, not due to any shortcoming in the quality or design of the model). I'm very pleased. I'm just sad I have to wait until the morning to get the replacement part. I should have stocked up, but I honestly had no idea what would go first. Now I have an idea.
