To each his own. I am using the new stiffer pads supplied by CSM for the micro. Footaba has it right. The very soft pad resonates the gyro case on the micro, if the helicopter has vibration. The first mounting pad CSM supplied with the 560 is just that mushy.

We mounted a 601 gyro on the mushy pad that comes with the 560 micro in a fury, the 601 saw all the vibration as well mounted to this flimsey pad. We then mounted the 560 back on the fury helicopter with the thiner pad, it worked as perfectly as a gyro could.

In any case, the firmer mounting pads are the only pads I will use now when mounting any gyro. I have had good experience with the stock 560 mounting pad for the most part. In a helicopter with a little vibration, the thinner mounting pads clean it all up on any gyro . Again, CSM has introduced a thinner firmer pad for this exact reason. It is the only one I run now with no trouble what so ever. Even in a helicopter which is less then perfect concerning the vibration.

Now of course, if you have a helicopter that looks like three helicopters in the air, while flying from the vibration, here is my take on that issue. If you are flying the one in the middle because it looks like three helicopters in the air, no gyro system will work to it's potential on a helicopter shaking like this. Thin or mushy mounting pad. Get the idea? A thin mounting pad should also never affect the sensor in the gyro, if the helicopter only has the normal amount of vibration. I see no problem using a thinner and firmer pad like the one supplied by CSM at this point. My helicopters run and hold well using the thinner pads on the 560 micros.

Staraero1,

I've not had that problem,but i don't have cheap varifocals, take hallucinagenic substances,or fly when still pissed from the night before


Seriously though,i have some mounting pads ordered,which could end up being the newer type, so i'll see what they are like in comparison

Quick UK are doing some foam tape now in two thicknesses.I have one of my older CSM 560's mounted with two strips of it (i didn't have any CSM stuff left)but i'm not happy about the damping it provides.Sure it'll work and might work really well,but the damage it might be doing is largely invisible until the damage is done,usually it's subtly progressive,if you know what i mean.

They may not have changed due to a performance issue
,it could have a fairly boring explenation, like current supplier
/manufacturer gone bust or found cheaper supplier.One thing i'd be concerned about with trying thinner pads with a micro (even though it is now lighter,smaller base & has a lower CofG) is that presumably the PCB is no longer floating in a rubber case spacer,it looks solid to the case now.

I personally feel that if it didn't/doesn't perform well with the extra cushion type pads, that the vibration should be cured/lowered or the gyro tried in different location on the heli.

Does it matter if you are in HH or NON HH when u swith the RX on? or does it matter also when u start to hover if your in HHb Non HH

Hi scouse,

It does not matter in normal if you start up the CSM 560 in standard rate mode, or heading hold mode. I set all mine up this way and start up the gyro in rate mode in the normal flight mode. I use heading hold in the other three flight modes. The reason I do this is so I can run the auto flight trim first flight of the day. You can set normal up like this, or use it in heading hold if you like. On the 8000 some people run the exact same pitch curves in normal and idle up one. The only difference id they set heading hold mode in normal, and rate mode in idle up one. All the other curves in idle up one are set exactly like normal mode. Then you can flip the flight mode switch between normal mode and idle up one in a hover to flight trim the gyro. For aerobatics they put the throttle V curve in idle up two, and heading hold mode in idle up two as well.

You do this if you want heading hold mode in normal mode, and access to the hover flight trim function of the gyro using the 8000 radio system. I do it the other way because I never use normal mode in flight. After the helicopter comes up to speed in normal mode on the ground, I flip to idle up one before I lift off to fly. After I land I switch back to normal flight mode and then pull the throttle back to idle. You can set up either way with the 8000. You of course can also use the gyro switch up in the top left hand corner of the transmitter to get rate and heading hold changes, but I always dial them into the four flight modes and never use the gyro rate switch. The gyro rate switch on an 8000 actually has eight different gyro gain settings in conjunction with the four flight modes. Just put minus and plus numbers in the flight mode pages of the gyro and leave the gyro rate switch down and don't bother with it. Everything is then selected from the flight mode switches only. Then you end up with four gyro gain settings and gyro modes, based on the minus and plus numbers placed in each flight mode.

I never fly in rate mode anyway. I just leave my normal mode set in rate mode to do the five switch flips in a hover first flight of the day. I always go to idle up one to do anything other then hover. My normal flight mode is set for gyro rate mode, a plus 80 number or better. Then my idle up 1 and 2 are a minus 80 number or better, both for heading hold mode. The throttle hold or auto rotation switch as it is called in the radio is also a minus 80 or better number for me.

So anyway the answer is you can turn the CSM gyro on in rate mode, and it boots up fine. Just don't move or touch the helicopter until the red light comes after you turn the reciever on. Are you using your CSM gyro in a helicopter with a driven tail in autorotation? For example, the raptor helicopter has a red gear stock. This lets you spin the blades without the tail turning. There is an optional white belt drive gear for the raptor which lets you keep turning the tail when the main rotor is turning. It makes a difference how you set the gyro modes up depending on which tail drive system you have. The constant white drive gear option on the raptor is better for gyro performance in the long run.
