Status: offline 		I just bought a gy240 plus a 12 amp esc to upgrade. The heli is stock except for a direct drive tail.
So the gyro will do the beeps initialize as far as i can hear, but my tail has no spin none at all?
I have also just put a new 3-1 E board on the heli also which has three screws instead of one and 2 plastic dials so now im really screwed ? anyone have a eboard with screws in it if so send me a pic of your working helis e board please and thank you?

So im confused I have a heli worth 150 + 200+ in electrics and all it will do is spin in circles with no drive to the rear motor, Im frustrated if you have any suggestions ideas please help

Status: offline 		Well I would go Right then beep the left then beep then try and nothing never went right left right?
But I dropped it off at the LHS they said bring it by no problem we will check it out for ya so hopefully the heli expert there can get it going for me.

Status: offline 		Well I talked with my LHS and this was tried.

All connection's were tested and everything is hooked up correctly.

New speed control added same thing no gain from the tail.

Then the gy240 was tested with a different gyro initializes fine.

My questions is would E-Board screw setting have anything to do with this I had recently installed a new E-Board from factory, could that be not set properly and causing 0% tail gain?

Or should I use a smaller speed control ? 7am ESC instead of the 12amp ESC? or maybe even higher? 25amp?
please if you have installed a gy240 on your axe cp and input would be helpful.

Thanks in advance and a big thanks to PilotLight & blvdbuzzard.

Status: offline 		I gave all the parts to my buddy to try a seperate package, today he tried the arming of the tail, he had no problems. I gave him a walkera g006 gyro, a eflite 5 AMP esc, a electrifly 25 amp main esc. The only thing he screwed up was he had the pitch and alerion servos swapped on the receiver so it was pitching the wrong way on the back side of the swash. Now, when he powers the main esc(25 amp), the tail gyro initializes and then you move the rudder full left and then center. In your case, you may need to hold full left or right when powering up the heli, then go full opposite of that command, then back to arm it. But the sad part is, while playing with the helimax transmitter, I think I found what makes it glitch, the servo reverseing switches. Make a long story short, while playing with servo plugs and swaping servos I reversed the switches and everything was fine, well I switched it a few more times in the setup and low and behold, in normal position it did nothing with the stick moving, switch it bach and it would work fine. So here I am trying to find out why it will movw the servos in one position on the switch but nothing the other way. As I go to switch it from normal to reverse just lightly touching the switch with a allen key makes all the controls glitch. No matter how softly I touch the switch, the receiver glitches. I'm just guessing it's due to the cheap parts used in this heli to keep it under $200, RTF. Other than that, it works perfectly with a std HH gyro and a 5 amp esc on the tail and a 25 amp esc on the main.

Status: offline 		I installed the GY240 gyro and the Electrifly 12amp ESC in accordance with Heli-max installation instructions, exactly. The helicopter flies perfectly. No problems at all. Check all of the wiring connections, especially to the receiver. I don't see how a new E-board could be effecting it.

You are using Lipo's correct. Upon plugging the battery in, I get a series of beeps. I then go full right rudder, another series of beeps, then full left rudder, a few more beeps. If then I go right rudder again, the tail rotor spins. I have been flying with this now for over a month at least once a day.

Status: offline 		Well mine has initialized but the rear motor does absolutely nothing no spin.

Does the ESC come factory set for lipo or NICD ?

I have no touched the jumper on it now that I think of it I took it out of the case and soldered it to the power connect and connected it to the gy240.

Status: offline 		Are you sure the tail motor isn't burnt out. As soon as I installed the gyro and the ESC, my original tail motor burnt out. I replaced it with a GWS motor and have not had any problems since. You could also check to see if you have voltage at the motor using a voltmeter. I don't have mine here right now to tell you what it should be for sure, but you should have some kind of voltage at least over 3 volts.

Status: offline 		Update

My friend seridium finally go the call from the lhs that his heli is now working. Apperently there is still an issue initailizing sometimes, but it works..........

LMAO- in a sad way.

Before I could finish typing this updated reply for seridium, he arrived with his heli, plugged it in and things went crazy. The heli servo's were twitching (a bad sign even to my limited experience) and then it started up without imput. Lucky I was around to pull the plug while he held it, he escaped with only minor cuts.

This happend in the company office by the way. LOL

Well, its time to send it back to heli max and let them deal with it. They said to send it in and they will look at it. Of coarse they said they have to test it to see if the broken parts are their fault, but considering the heli is using a BRAND NEW E BAORD they sent, I can't see it being a problem.

Thanks to all who offered advise. Hopefully seridium will fly again someday.

Status: offline 		I just put a GY240 in my AXE. The install was a simple one. I am using the stock 3 in 1 board and the 240. I pulled the orange wire from slot 4 of the Rx. I mounted the 240 onto at the rear of the frame. I plugged the 240 into slot 4 of the Rx. I then plugged the orange wire from the 3 in 1 into the white wire on the female lead of the 240.

First flight was not good. I broke the tail rotor. I replace it and then turned gain down. I started at 75%. I turned it down to 50%. Still no love. All over the place. I remembered that you need to turn the gain on the 3 in 1 down. I did that and then it would just spin. I flipped the REV switch and all was close. I turned the gain on the 240 down to just under 25% and there is just a tiny bit of wag.

Seems to drift nose right at about 45 degrees in a couple of minutes. That is close enough. I also put on the bell hiller mod. They work pretty well together.

I flew out a battery just flying side into the wind. Seemed to hold well, did not get blown around like it was with rate mod gyro it comes with.
