View Full Version : Can HH gyros be used on any heli?

I was thinking about getting a gyro for my esky cp2, with the thought that I could possibly use the same gyro later with a trex -

Am I correct that any gyro can be used with the 4-in-1 on the esky cp2 or Blade cp, cpp?

If so, what is a recommended gyro, and why are some so much more expensive than others?
I was thinking of $50-$100 in price, but if there is no compelling reason to get a nicer one....

I know you COULD use a 401 on a CP Pro, but was warned not to because of the weight.

I have a G90 and an Align knockoff (almost idectical to the G90)

I believe (but don't know for certain) tha tit will also work on larger helis, but the reason people go with the more expensive ones is quality/usability.

I'm tempted to pick up the Logitech one, because it's almost as light as the G90, but it's "real" full function gyro. (well, it's one that Trex guys are using)

I use a 6g Telebee HH gyro on my CP2 with Telefantastic results. Works well with the ESky 3-in-1 or in full separates. Currently I use the Telebee with a GWS ICS 50 J esc to manage the direct drive tail on my brushless CP2.

The G90, Align, Zoom and Telebee are close cousins. The G90 being digital ready.

What does digital ready mean?

And can this work with the 4-in-1?

Thanks!

Digital normally means that the gyro supports an increased frame rate for digatl servos. This means the tail is held better, but this mode will destroy analog servos quickly.

It is hard to use any external gyro with a 4 in 1 because it needs to connect between the Rx and the tail ESC. There aer hacks around.

well, yes, any gyro 'can' be used on any heli. however, because the blade has a motorized tail, not even the best of the best gyro will do much better than a telebee/zoom hh gyro. and weight matters. however, on a belt drive tail or collective pitch tail, (esp with a digital servo), different gyros does matter. and if you use a telebee/zoom hh gyro let's say on a 50 size bird doing 3D, it's not really a hh gyro anymore cuz it's not going to hold the heading very well. so that's where you need the top end gyros.

You can hack in a Telebee 6g hh gyro in a 4-in-1. Split the pcbs and run a jumper acrosss ch3 and main esc. Connect gyro to ch4. Connect tail esc to gyro. Do not connect gyro sense lead to rx so you will be in HH mode.

There is a possobility of crosstalk between the 4-in-1 gyro/mixer with the hh gyro. If this happens, use a GWS ICS50 esc for the tail. Connect the gyro to this instead of the 4-in-1 tail esc.

Give this guy props! Where were you when I 1st got my CP2 man? :hug:

I assume this isn't an issue with a motor tail, since there's no tail servo. Is that correct? Can the G90's digital mode be used with the stock BCPP 3-in-1, or do you need to use a separate ESC for that?

G90 will work with CPPro...its made for it (by I think Telebee), not sure about digital vs non digital and its an improvement, even in rate mode. The nice thing about the Eflite radio is you can control the gain from the TX. The gyro plugs into the rudder ch4, the 3:1 rudder (esc) plugs into the gyro.

I don't know if it will work or not, but E-flite says to use it in analog mode... :dontknow

i think kyle's using it in digital mode.

I just tried digital mode. Warning: I'm a noob so try at your own risk. You setup may be different than mine. Wow. I don't use the 3-1 cause I have a tail ESC with BL motor but WOW. I ran three packs, stock 800mah pack, Custom RC 1000 mah and a TP 1320mah. What a difference. It was actually harder to fly for about 10 seconds because I was so used to correcting the tail so when it didn't need it I almost crashed! Wow, definitely helped my bl tail setup. Why didn't somebody tell me about this earlier? Gain is more sensitive so be careful. Make sure you adjust gain before getting slappy on the sticks. I st my Gain to 100% on the gyro and about the thickness of the black line on the knob past the first dot on the HH side or simply, about 62% from zero. Again try at your own risk but dang that sure did help!

sorry i may have missed this, but buzzkill dont you have the stock radio ? i always was told that unless you have digital servo's never use the digital setting.

Yes I have stock TX. LOL I aint scared. Now before I get labeled a "******ladite", I warned people to try at their own risk. There was no animals, people or danger to myself with the test flights. Yes this could damage my heli and anyones that tries it. I have an old digital cam that can take movies in really poor quality but I'll take one anyway and try to post it. Judge for yourself. I am a noob. I do not posses 1/1000th the knowledge of most people on Helifreak. Maybe I have more balls than brains or I just like throwing my money away? Hey someone had to try it!! :D

well, i think all that is to is is higher frame rates, which could mean more imput to the tail per time frame (ie. sec.). this is what i SPECULATE and have no prove, but i think all this does is make ur tail work harder, that is... if your tail esc can actually keep up with that many imputs per let's say sec. so as for you AND kyle both uses separate tail esc's, those esc's will likely be able to keep up with the imput more or less, i believe that they are faster than the stock esc in the 3 in 1 esp. buzzkill has a bl tail. so making ur tail motor work harder will highly shorten it's life, just like using a analog servo with digital mode. however, due to buzzkill's bl motor response and esc response, he's getting a much better result than using analog mode... AND he's got a bl tail, which means really, doesn't affect the wear and tear of the tail motor that much.

the above is only IMO though.

Well I'll have to wait for day light the vid I took was way too dark. I'll take it to work and try it there.

Chopperdudes is right: http://www.helifreak.com/viewtopic.php?t=34557 last post. Looks like the Stacys use digital mode. Ginocp could probably shed some light on this subject or Ray ?

High winds and snow. I'll try again tomorrow. Didn't mean to sound defensive earlier.
