Shaking when doing tic-tocs?

[chugga-bug]

What will cause the shakes when doing tic-tocs?
Just started trying them with my Knight 3D.
Is it just me and my heavy thumbs? or something else?

OS Hyper, Magnum 20, revlock, radix @2000rpm, and standard clear dampers.

Dampers could be an issue...
Are you using Spektrum Tx/Rx gear and doing some "crack tic-tocs" without realising it

Care to explain please??

If you are to heavy on the reversal with your cyclic and collective causing the headspeed to dip, then that will cause it.

what is it like at Rainbows (long tic tocs)

[Leebert]

Is it a spektrum issue as it is a faster system then?

[robgt]

2.4 Ghz introduced the ability to perform new manoeuvres previously not possible due to latency - I think Alan Szabo was first with these, and they have become known as Crack [manoeuvre name] - i.e. crack kaos, crack rolls, etc.

The speed at which the stick inputs are now being transmitted to the heli, and the speed at which the servos in the heli respond to those signals is really fast. Any slight stick movement is now seen on the heli - it's awesome

Me and my mate have the same radio control nitro cars, he has some cheap servo slow servos on his running on 4.8V and I have £100 Ko-Propos running on 6V. We went out the other night and swapped cars but I could not drive it as the delay in steering, accelerating and braking was massively noticeable, my mate also commented on how great the feeling was on my car as every thing was instant and snappy.

When I first moved from my FF9 to the DX7 (about 12 months ago) I crashed my Raptor on the first flight. There was a noticeable difference and it definitely felt like me and the model was linked better and felt sharper.

I crashed because it was dark and I got disorientated

uh huh!

yes I am using Spektrum.
Must admit it probably is my hand shaking more than anything, but I tried a couple of rainbows and it did it still.
I can do them pretty well on phoenix but I haven't pulled off any decent ones for real yet..
What would the issue be with the dampers?
They are the original 'clear' ones that came with the kit, been silicone greased and have done no more than 2 gallons worth of fairly mild flying.
It was today (Monday) I was flying so the dampers were pretty cold (Hard). I would have thought this would be worse with soft dampers?

[robgt]

The dampers can become dented after a while, especially when 3D flying as it is pretty hard on dampers.
If you take the feathering spindle out, you might be able to see if the dampers are worn or not. Look for non-circular inside holes (where the feathering spindle will have been hitting them top and bottom).

I'm not sure if these dampers can be rotated to get more life out of them or not - I suspect they can - in which case, turning them 90° would be like having new ones in until they wear down as normal again.

Thanks for the reply Rob, but I don't think that's my problem. They've only done 2 gallons of pretty tame flying.
It's probably just my lack of skill that's causing it!

A bit more practice is probably the answer!

[robgt]

A simpler way to check for damper wear is to open up the main blades and simply try to rock them (on the aileron axis). There should be a minimal amount of play, very small, any more than a small amount of play here shows worn dampers - and that will contribute to less stability in flight.

You say tame flying, but manoeuvres with sharp pitch reversals, such as tic-tocs and rainbows, will wear dampers out...

Dont know if its the same thing but ive got a shake on my Knight that I have mentioned on here before, its quite a bad one but only when the blades are slowing i.e. when comming in steeply with the throttle well down.

The only thing I can think it is is something to do with the dampers that turning them 90 deg sounds a good idea to me.

so maybe we have the same problem. mine came about after a blade hit the ground.

[Nutz]

The only time I get the shake or as Trvo would call it "the Raptor nod", is when I over cook it on a wall or any maneuver where I slam cyclic and collective together and end up killing to much H/S.

The key is feel for the limit at which you can push it.

[Ade_Law]

its commone for people to just slap the cyclic and collective back and forth. even tho its quite an aggressive move it still requires finiess in the cyclics and collective in both movement and timing.
