Logictech LTG-2100T versus the Futaba GY401

[brovic777]

Here is the "battles of the gyro's BAMM test" that I did to see if I could get my new Logictech LTG-2100T to work as good as my Futaba GY401 gyro using the same super high speed new Futaba s9257 Digital Tail servo in my Thunder Tiger Mini-Titan e325 Heli.

Here are the results of my quick preliminary tests:

I got the Logictech LTG-2100T setup finnaly correctly. Works awesome now.

Here's my setup procedure!!!

--------------------

First thing to do is setup your radio to not change the DX7 gear to gyro. Leave gear as gear, and setup the gain pluged into the gear channel on your reciever as normal to adjust the sensitivity settings. Then, on your DX7 settings, go to your travel adjustment and change the gear value to +66 -64. Your +66 is your TL and your -64 is your rate mode. You should have a gear switch on your tx that up is 0 and down is 1. When you hit the switch to 0, your in TL mode, when you move the switch down to 1, your in rate mode. You must set it up like this to adjust your gyro then mechanically.

Now set the rudder travel adjustment on your transmitter to L-150 R-150.

Go to the gyro, and put your piro rate at the 3rd light from the left.

Now, make sure you gear switch is down on the 1. If you don't have a DX7, I have no clue how to set it up on yours.
Now that your switch is down, your in rate mode.

Now try to hover while in rate mode, you will probablly have to control it with your rudder because it will move either left or right, depending non how off your tail servo mount is. If your heli stays perfect, then your done. Unplug your battery. Put your TX gear switch back up to fly in Tail Lock mode, green light is on, on the gyro. If your heli is not straight, then you need to manually adjust either the placement of your servo mounted, or if it barily drifts to the left or right, you can do a couple of turn on your linkage rod connecting to your servo. Keep playing with it till your heli can hover with no drift to the left or right in rate mode. This is a pain in the butt, but must be done for your Logictech gyro to work properly.

Never use the trim rudder setting on your DX7 and make sure it is always at
0. If you try to set a value on the trim to adjust any tail drift, it will confuse the gyro and mess it all up. It must always be at 0.

Once you can hover in rate mode with no drift to either the left or right, your gyro is now ready to rock and roll.

Unplug your battery. Then on your DX7, change your travel adjustments on your rudder to a value of your choice over 100 to the L and R depending on how fast your want your piro's to spin. Try 120 on each and see if you like how fast your piro's are.

Now put your DX7 gear switch back up to point to 0 to put your gyro in TL mode. Plug your battery back in, and have some fun doing some massive 3Dz!!!

The pro that set this up for me does not use the Futaba GY401 anymore as he says the Logictech is way superior!!!!

Have fun trying to figure out what I just posted. This is the craziest setup I've ever seeen, but it work for me!!

Which gyro is better

[brovic777]

For a 450 size heli, the 401 is way better.

For a smaller super micro heli, then the Logictech is best to save weight.

I don't agree, the GY401 doesn't have a consistent piro-rate AT ALL. The only really really big plus about the GY401 is that it's dummy proof... no need for a good setup, it will work anyway.

True, the 401 is very much dummy proof. Good term BTW. :)

Even after a crash, you up and flying with a 401, while the person with a Logictech has to setup it up in rate mode all over again. By the time the Logictech is done, you already have 5 flights in with a 401.

I'd rather be flying, than messin with the setup ever dang time after a crash. Then again, I hardly don't crash no more, so I guess it wouldn't matter as much. )

I dunnow about you, but it takes me about 1/2 flight to get the rate mode set accurately :) . And I do like a consistent piro rate ;) Especially after getting use to using GY601 / Logictech 6100's its hard to fly a GY401 again.

I'm glad that we agree that the GY401 is dummy proof and therefore very good for beginners :)
