I got tired of my Blade doing altitude changes with no control input telling it to do so. I think 4in1 is bad, but had enough parts to put together another heli, so bought a GWESC480 for main motor, GWESC300 for tail motor (as the GWESC050 I bought will not arm) and a PG-03 gyro. I have everything wired up and it seems to work as motors turn in correct directions. I am using a Hitec Electron 6 receiver and a Futaba 9CHPS transmitter.

When I give it throttle, motors start turning, but once it hits point 3 on throttle and revo curve, tail will just take off. It actually spun so fast it caused tail blade to hit ground and break. Am I missing something? I bought those ESCs as I did not want to go brushless and they handle 2-3 cell Li-pos. I have tried various gyro settings and tail still goes crazy.

I am sure it has to be something simple as when I look at:

I am basically doing the same thing as they show for the brushless setup. I think there is something wrong with the schematic they have for the brushed setup as they are showing a mixer, but they are not showing it in photos.

Using this schematic for the normal brushed set-up did you get a mixer?

Why would I need a mixer? They do not show one for the brushless set up, and if you think about it, the brushed set up is really no different. Also, if you look at the photos they have next to that schematic, they are not showing a mixer, so I think they may have made a mistake. Now whether mistake is in the schematic or the photo, I cannot say, but if brushless does not have mixer, why should brushed?

I agree! I have set two machines up brushedfirst and then burshless without a mixer, just using the mix in the TX. Some of th HH gyros need no mix as long as they can arm the speed control (full nose left).

Gyro is not heading hold. I am using revo mix on transmitter, Works fine until I give command to turn, then motor speeds up and will not slow down. It will keep spinning the heli.

Brushless has no mixer because in the diagram they're using a GY240 on the gyro, negating the need for any mix at all. The brushed setup uses cheaper components and thus a cheaper rate gyro, which requires either a mixer (or) a transmitter with revo mix points. The diagram (and article) was based on a cheap route and expensive route comparison, which is why the images differ in the setup they show.

If you were using a rate gyro instead of HH, and you're not using a mixer, simply use the brushless wiring diagram and replace brushless motor with brushed and you're good to go.

As for the problem you're having, it sounds odd. If you punch or chop the throttle, is the tail swinging? Is there ANY stability on the tail before you give rudder command? It could be possible that you just reverse wired your tail motor or installed the prop wrong. It's also possible your revo mix is setup incorectly, and it's applying reverse input at revo point 3.

Btw I don't really I know I was just posting my best guess soley based on that diagram perhaps I should just shut up.

Turns out it appears the instructions for the gyro are incorrect. They show it mounted to side of heli. LHS has one someone built using same gyro and I recalled that person mounted it on rear. Did same with mine and problem seems to have gone away.
