Blade mSR jumpy tail?

[kaelmythe]

After playing with a few coaxials a number of years ago, I stumbled across the Blade mSR and - after some research - decided to get back into this whole flying (read: crashing) thing...picked up an mSR off of Amazon due to lack of LHS's where I'm currently at and so far it's been pretty amazing (went through an entire battery without a crash...which is my greatest accomplishment in RC flight heh) - but I've noticed a few things...

First, people here have mentioned they can, with proper trimming, get their mSR to basically hover hands off - mine seems to go through like a vertical loop when I take my hands off...it travels back and up, and then forward and down...but this isn't really that discouraging as I'm sure it has something to do with my trimming and really doesn't effect flight...what does is the tail. I've noticed that when I try to hover it completely still, the tail will jump a few degrees to the left every few seconds. It's not so much that I can't correct it, but mid-flight when my poor brain is trying to do so many other things, it's thrown me off before. I'm not sure if this is normal, or if there's possibly something I should be checking out?

Thanks in advance for any help!

Kael,
My mSR exhibits a similar symptom.
The tail motor does not run smoothly. It sounds like the tail motor constantly and quickly switch between low and high speeds. The tail motor sounds "z...z..." but not a constant long "z." No matter how I trimmed the rudder, the nose will slowly yaws left or right, but never really stay in one place.

Anyone know how to fix it?

Thanks!

Hi
Are you holding the heli when you plug in the battery?
These need to be as steady as possible when powering up for the gyro to initianalize properly
I place mine on a solid surface plug in the battery pack and only after the blue light is steady do i move it

Hello Hank,
I placed the heli on the floor, connected the battery, let it initiate, then slid the battery in its slot. I tried laying the bird on its side (recommended by HorizonRC video) and put it up on its skids. Did not make any difference.
The heli is very stable, but the tail "vibration" make the heli slowly rotate.
Best,
Nick

I did a search last night. It turned out many mSR owners have had the same complaint. Hope Horizon would fix this, or I need to look the other way.

I wonder if the Novuses are any good. Helimax also market a sub-micro Novus CP too.

Hi Nick
Lots of issues with the Novus line and they are rebranded Walkeras in the first place, did you know that?

Hank,
I did not know that! I thought Heli-max and Walkera were two different brands/manufacturers???
Were you talking about these:

Thanks, Hank.
I should stay with the Blades for a while

Mine does it too. I'm thinking its a price we pay for the lite weight. I don't think it makes many more differnece than trying to hover near a air vent or fan. Just par for the course. But i'm no expert. I'd be happy if someone found a solution.

I'm not sure if I was aware of that. Thanks for the tip!

I've had mine for a week and it does the same thing. It sounds kind of like a mosquito buzzing around. There does not seem to be a sweet spot in the rudder trim where the chopper will stay pointing in one exact direction - it always wants to rotate. I trimmed and straightened a brand new set of main and tail blades with the same result. I am wondering if a better transmitter might be able to adjust the rudder trim properly or if it might be a problem with the board. I am going to contact the manufacturer and see what they have to say about it. If it's normal behavior then fine, but if not I want it fixed. I have not seen any threads on this exact phenomena except for this one but I've tried to start a couple with no replies.
