Time to Change to 2.4Ghz..... HELP!!!! :)

[MrHolloway]

Hi yes I am sure I'm miles behind with this!

So I have a Shuttle with a Futaba FF6 50th Edition. My Gyro is a ICG400. Since getting another RC Plane and messing around with the Tranny, now when I take off with my Heli the tail violently spins round out of control! I must of done something to the Tranny???? I have taken it to the Model Shop and they looked at me in disbelief I was using the old 35Mhz and confirmed the GYRO is correcting in the opposite direction. Anyway Since then I have bought a Futaba T6EX 2.4Ghz Tranny and a couple of R617FS. One for my Plane and one for my Heli. So.. The planes a doodle to setup and all sorted.. The hell on the other hand I have no idea. Its the GYRO that confusing me. So a couple a questions.... Is my GYRO old hat and best get a new one for my new Tranny and Receiver and if so whats the best one to get thats easy to setup???

Any help will be most appreciated

Align gp750 are cheap enough and a doddle to set up , plenty of videos showing the steps .

im guessing that gyro you have has a old slow tail servo. so would upgrade tail servo also

gp750 , spartan quark or gy401 and a align ds620 or similar

[David Drew]

I have both GP750 and Futaba 401 on helis and they are a doddle, reliable and more than capable of anything I can do. Just use a decently fast digital servo as suggested.

Go fly!

Not to cut across anyone but the gyro the OP had worked before he fiddles with the tranny, The ICG is a heading hold cheap gyro and before changing to another better unit it would be better for him to sort out the setup which is obviously wrong.

If I remember right the ICG400 is a HH gyro with the gain channel working in the traditional way IE low ATV rate mode high ATV HH mode. To the OP what did you fiddle with that caused this behaviour, does the rudder work in the right direction IE left stick left rudder or has that been reversed. Has the gyro sense been reversed, have you selected this on the gyro by mistake. The way to check is to turn the bottom blade of the tail hub so that it sticks out like the rudder of a boat and then slowly move the heli one way, the blade should also turn in that direction. The other thing could be a bad mechanical setup that biases the direction of the tail in one direction and you've lost the gain channel for the gyro so you've ended up in rate mode

i would look up the csm web site and down load the instructions for the gyro
and reset the model up
as you have messed up the set up to the gyro fiddling with the radio
the switch used to move between rate and heading hold mode is switched on/off to set into the set up mode
gyros have come on a long way since the icg400 but it is still more than good enough to use on a shuttle


btw there is nothing wrong with a 35mhz radio
it is now the safest its ever been as most have moved over to 2.4ghz
many fixed wing pilots still use 35mhz without problems

If tail pitch is set correct it shouldn't spin round fast. If in rate mode if slightly off the heli will turn slowly and HH it should try and hold a little. It could be a number of things going on here. If I was you before spending any money do a complete set up again. Making sure there is no trim in tail in trany, make sure pitch is there or there abouts in rate mode because if set in rate mode the heli will still hover and fly HH helps thats all it also help get over a bad tail setup. Check its working correct way and corrects aswell do end points again, re do gain and check its switch between HH and rate


to answer question your gyro is old yes but unless its a big ding dong or packed up inside there is no reason why it shouldn't work, most of us on here would of started off will similar setup to yours

[MrHolloway]

Thanks All. So will my GYRO work with my New 2.4Ghz Tranny and Receiver? Am going to change over tonight and see how far I get

[waveydavey]

It will work fine, just make sure you get the channels correct and the assignment in the Tx

[David Drew]

Maybe get someone from a local club to help you? It will save a lot of time and head scratching!

and if they say X part is no good you need Y part to get it to fly
you should buy a new model, take the heli to somebody else

the ff6 and the new 6ch futaba 2.4 ghz radio will use the same channels in the rx
it sounds like you have reversed the gyro when you tried to set the plane up

OK, I formally withdraw that suggestion!! But if gyros are a bit of a mystery then maybe a second head on the issue.

Is this similar to the CSM420SL?

If not used to setting them up it can easily be reversed in the step that deals with this and I recall on mine every time you want to set something you have to go through all stages of install.

They say to check certain preliminary things are off like revo mix.

[electricsceadu]

if i remember correctly yes it is very simular in its set up
and you need to go through each step to complete the set up
no revo mixig is used

Well in that case the servo direction should be checked with the gyro out of circuit, right stick gives right turn, then do the install and ensure the left turn by the heli is corrected by the gyro and set accordingly if not.
