Logictech 6100T Gyro Setup Videos

Yes it is OK
Normally the "4.8V" systems are designed to work with 4 NiCd or NiMh cells with a nominal voltage of 1.2V/cell, but in a fully charged situation they can be as high as 1.3v/cell or 5.2 V. This "over voltage" is normal and the servo should be able to handle it no worries.

Hi Bob,
Thanks for your videos, they were great. I got my raptor 90 mech trimmed but I have tail wagging like crazy in normal and heading lock mode. Sound like gain to me. I saw in your video you set the your gain to 30, performance to "high" and smooth to 18. Since the gyro requires 51% or more for HH where exactly are you setting the to 30%. Thanks in advance.

You just read the value at the gyro and set at the Tx!

It's always too windy in the UK at the moment to set up the tail in rate mode, keep getting false drift.

I've got it set up to the point where i can fly and preform some acro without it stepping out too much though, and i'm impressed with it so far.

I'm using mine on a T-Rex 500CF and am just building another 600E and using one on that too.


So... My question:

Once it is set up spot on in rate mode - will it hold in HH during headspeed changes, ie: when i fly in normal mode on a setup of 0 25 50 75 100 - as currently it's stepping out quite badly in normal mode, in idle up one of 100 95 90 95 100 it steps out too, but isn't that bad on idle up two which is 100 straight.

[Finless]

The 500 tail doesn't like low head speeds. If you head speed is low the tail wont have enough power to compensate for torq especially if your over pitching and bogging it. No gyro will work if this is happening. So you your tail is not holding make sure your head speed is over 2600 and your not running more than say 12 pitch. At 3000 rpm you can run up to 13 pitch no problem.

Also I bet your running the 12T pinion? If so head speed is probably WAY DOWN on your normal curve you have set right now.

Bob

[JeromeF]

Thanks for the reply Bob.

I'm using the 13t pinion and i'm using ThunderPower Extreme V2 6S1P 2200mah, FlightPower Evo 25 6S1P 2170mah and i've one FlightPower EvoLite 6S1P 2500mah pack i use for crusing.

To tell the truth, most of the time I will be flying in idle up - but i would like to use something like 100 90 80 90 100 for one of the idle up modes.

I've not had chance to get my eLogger on it yet but using my friends calculator it shows i'm getting around 2900-3000rpm.

So do you reckon once setup perfectly using the 100 90 80 90 100 curve i will get no step outs?

[JeromeF]

Oh and do you think a more of a flat curve on normal mode would be an idea? On my 450 i use something like 0 80 80 80 80 ( would have to double check though).

[Finless]

the 100,90,80 curve has you pretty low in the middle. Enough that as you transition from positive to negative you should hear a head speed drop. Electrics love to build head speed when at 0 pitch and this helps with bogging when you nail in a lot of pitch. Most everyone I know runs either a 95% or 100% flat throttle curve in idle up. No V curve at all.

Bob

[JeromeF]

Ok cool. Well i shall just keep a flat curve, 95 in idle up mode 1 and 100 in idle up mode 2.

Thanks for your help.

I just put a new 6100T on my raptor titan. I set it up via Bobs videos, which were very helpful. The problem I'm having is that the tail has a constant wagg. In normal mode (50% gain) after setting up for no drift, the tail will slowly drift left and right in a hover with no rudder input. Note that in normal mode its seems intermintant. In tail lock mode (30 to 50% gain) the tail waggs constantaly, approx. 3 to 4 inches. Also in tail lock mode the servo will slowly drift towards the tail, on spool up and just sitting on the bench. I have to constantly bring the servo back to center with the rudder stick on spool up. I have no trim or subtrim in the rudder. I've tried to add subtrim to counter the servo movement but that just makes the servo bounce back and forth. I"ve been through the tail assembly more times than I can count and its smooth, no binding. I'm using a Futaba 9c radio.

[Finless]

This gyro is REAL picky about having a silky smooth tail system. When I put the Kasama tail on my e620 I had a constant very SLOW wag. I had to sand the output shaft and make sure the tail was super easy to move with the control rod. Even then on a cold day I will sometimes get a little slow wag from time to time.

So make sure your tail is smooth! On a raptor that includes checking it with the control rod all the way from the front of the heli. The rod guides must also be smooth.

As for the servo going to one side just sitting on the bench I recall mine doing that as well but not sure. I will have to double check when I get home.

Bob

Hi Bob, I saw the video on the Kasama tail with the wagging. I put a Kasama tail on and thats when it all started. I've since removed the Kasama tail, (it caused a major static problem and radio glitch) just left the tail grips and put on a new tail slider using the stock bushings and not the larger Kasama bushings that dont fit. It feels smooth? I guess I should put the stock plastic grips back on as well.

[aussiemick]

Have you tried lowering the gain value in HH?
I know I had to lower mine considerably to stop the wags. I have my gain set at 36% in Normal and 32% in IdleUp and it is holding fantastically.

Yah I've lowered the gain in Taillock mode to 25% with no change. Whats bothering me is that even just sitting static on the bench, with tail rod disconected, in taillock mode the servo arm will bounce slightly back and forth 1 to 2mm with performance in standard mode. If I increase the performance to hight or highest, it gets worse, bounces faster. Dont know how to get rid of it, dont think its normal and if its the source of my wagging problem.

[hookmaker]

I have a 6100T and full Kasama tail unit as well. Had some slow wagging back and forth (same as with my previous Mavrikk tail unit). It all started when I moved from the stock TT engine to OS 50 Hyper. Thought the engine was running a little bit rich and did some "small farting" from time to time, but that was ot the case. Changed the stock plastic tail blades to 92mm carbon and now it´s holding.

I keep my system real smooth as Bob describes, and always set the 6100T up in normal mode to 0 drift before setting up in HH mode.

Hmm, have different helis with Logictec 6100T's that fly OK, but can't seem to get it right on a T600 Nitro Sport (belt) and a friends T600N Pro (TT):

1(Belt): modified T600N with a shortened Raptor tail boom and full Kasama tail unit and blade grips.

Tail keeps a continuous sideways vibration in hover, but flies OK. BUT this sideways "mini wagging" (not hunting) irritates me. Have fiddled with the Logictec for 3 gallons now and can't find the problem. Heli seems absolutely flawless. Tail system is super smooth and slides by itself if you lay the heli sideways.

Engine is smooth running - no kicking.

Gyro setup: Gain 52%, 3D, Highest, 125%/125%, 12% smooth control. No matter what setting same problem.

2 (TT): Same problem as above, BUT here tail also shoots 45-90 degress to the left at medium to agressive pitch ups/downs. Seems like the gyro can't find it's heading.

Setting: Gain 42%, 3D, Highest, 110%/110%, 0% smooth control.

Any suggestions will be appreciated.

How did you get the end points to be the same on a TRex600N AND get the heli to hover in rate mode??
I am using about 85% and 125% as end points and it flies great.

Mick, don't realy understand you question, we are talking limit on the gyro - not END points on the radio? My END points are set at 100/100 - I never touch those until I set the piro rate.

/Henrik

I too am talking about the travel limit on the gyro, yours are set to 125 125.

If you are setting the heli up to hover in rate mode, which is recommended with the LT6100, then the pitch slider will not be centred on the tail shaft. To stop any mechanical binding on either end you would need to limit the gyro on at least the side going towards the tail boom.

I have my Radio EPA for rudder channel set to 140% so that the numbers I read in the gyro are the same as the TX I then use Dual Rates on the rudder channel to control piro speed.


Mick

[hookmaker]

Mick, OK see your point. My slider is limited by the limits on the gyro and I control the piro rate using my EP on the Tx. However since I've tried everything, I'll try your way too. Thanks.

[bpd964]

Where is your gyro mounted?

[hookmaker]

On the top of the boom "clamp". But i've moved it up front, let´s see what today flying will show.

[bpd964]

Cool.. keep us posted..my combo is starting to stray left for a few then right for a few.. It's weird..

[cgbole]

Has anyone used a Futaba 9256 servo with the Logictech 6100G gyro?
thanks
