help with gain on G90 gryo

[Epoweredrc]

i wanted to know where you have your setting for your g90 gyro set at on your blade cpp i can not get this thing to hold the tail like it should, everytime I give power then decrese the power the heli turns to the right coming down. I keep playing with the rudder trim and the gryo gain on the TX but Can't get it to hold right..
anyone have this problem?

If you've got a 3-in-1, be sure to set that gain to nothing -- effectively disables the built-in gyro. Also, be sure that you're actually in heading hold mode. Lastly, don't forget to unplug the battery between any Gyro tweaks.

You didn't mention whether or not you're running a Blade CP or CP Pro. If you're flying a CPPRO, the gyro setup is pretty well documented in the user's manual. Blade CP owners can download it from Horizon Hobby.

I am flying mine with a Spektrum DX7. Rudder trim is centered. I've got a wee bit of sub-trim to right to keep the tail in place. I don't recall the gain percentages off the top of my head (set through travel adjustment), but they're nothing special. I've got the remote gain control setup on the GEAR channel. I can get exact numbers if you want a starting point, but those numbers are somewhat specific to each helicopter.

With my current setup, I can take my left hand off the controller. The tail is rock-steady and holds like a champ -- stock motor.

yes I have the Blade cp pro and the stock radio the 3 in one is disabled ( I have the 2 in one only uses esc and mixer)

well I have it in heading lock and have the gain to work on the radio, turned from center to the right about 3 o clock, and been playing with it, it seems I get it holding good for when coming off the ground into a hover but then more power makes it jump left or right..

turn the gain way up, and then keep toning it down until you get no tail wag but the tail holds

Ditto the advice.

at just before hover or in a hover? I am not sure where I should adjust, I adjest to not turn on ground then in air it turns, but its hard to adjust while hovering. at least for me.

so are you guys adjusting on ground or in the air?

[rabidguineapig]

after turning the gain up, get it into a hover, maybe a little FF, give it a punch of throttle, etc... and if the tail holds try turning the gain up more until you get wag, if there is wag, turn it down. you gotta find that perfect spot with the gain. try to adjust it while you are on the ground and then take off, don't change it in the air

Also, if the CP (Pro) is 100% stock, the gain will change as the battery voltage gets lower, requiring minor trim adjustments as needed.

A very true statement.
I do most of my trimming at about half way thru the first flight-that way the trims are "Averaged" for the Batt pack....-
Get a DX radio-makes life mo betta:thumbup:

oh really, well maybe thats something messing me up also

what way does the heli try to turn ? w/o the gryo my father thinks mine is backwards
does the nose try to go right or left?

[rabidguineapig]

THe only way to stop the power from slowly going down as the battery drains is get a batter battery... the stock lipos are junk. If you aren't planning on going bigger than a blade then don't bother, but if you want to get something like a T-Rex in the future get a better charger and a better battery for your CPP while you're at it... just my 2 cents

The G90 gyro works ok, its not the greatest though. Usually to get the G90 to hold well you need to use some subtrim, unfortunately the stock TX does not have that function. Get the heli to hold well in the air and hovering, don't try it on the ground, it just won't work well enough as the skids are helping to hold the heli in place. Crank the gain up until the tail wags back and forth, then turn it down slowly until the wag is gone. now try some FF flight, you may end up turning the gain down a bit more. The heli naturally wants to spin counter clockwise ( Left) as the blades are going clockwise ( For every action there must be an opposite and equal reaction ). The tail motor may also be getting weak, an inexpensive upgrade to Direct Drive will help alot too.

The biggest upgrade you can make would be to go with a better Radio TX, lots of options in the newer radios that help helis fly better. The stock TX is a POS with terrible gimbals on the sticks that are known to induce lots of noise.

Spektrumizing my Blade CP changed the helicopter. Incredibly worthwhile upgrade and unlike many of the other hop-ups, it's something that you can take and use with other models. If you're at all serious about the hobby, it is a worthy investment.

My stock TX is glitching constantly around center. Is there anything I can do to fix it? Like maybe returning the TX to the E-People for repairs? Or, if I put another radio in it, where can I find the the right settings for it? Thanks.

Hello there I just have a aling head hold gyro and y have the gain dail to 45% and in foward fly is great I olso able to do figure 8 and rolls and the tail hold very well all these with wind up to 5mph. but the things is that the tail hold very good but is not perfect in hover there is some amount of wag all i need to do is but some right rudder and help a lot. The things is that tail motor are not that acuurate that belt tail with servo so.

Check rchover for the "Glitch no more"choke----prevents some of those probs-also ferrite ring on the esc plug where it goes in the reciever-the tail rotor motor and the stock esc can cause this problem-right at center stick/hover-whenever the gyro kiks in the esc will put a glitch to the power and the collective--this cost me a lot of crashes as it was slamming itself into the ground fromm about 3 feet altitude.....get a DX7 radio and you'll be happier:thumbup:
