I have just read your previous post first of all I would test the tail esc but taking the gyro out of the equation. Unplug it and try without the gyro installed if you have no joy you know its your esc that you need to be looking at.

Make sure your tail esc is initialising properly, as we dont which your using I cant comment any further. But you should also check your trims are zero, and check to see that the channels are not reversed.

p.s excuse my spelling

well thanks for the ideas but I know now that is the gyro it is not puting out enough juice to get the tail esc to turn on. I have a wattage 2amp esc and I just got a new GWS 2amp esc and it will not work the volts out of this gyro is 4.30 volts and a normal signal out of my receiver is 4.60v and up the gyro has a defect and I am sending it to futaba today the hobby store that I go to will not take in elec. back so that is my only option

DO you have the +and- lines connected to the tail esc? These should not be connected so you arent driving 2 Bec's. There should only be a signal line coming from the gyro to the esc.

Hope that helps

sounds like the gyro was the problem, I just set mine up and had tons of problems with it. I put a new tail motor in along with the gyro and it turns out it was bad which made the heli go beserk. In adition my ics 50 was on the way out. All happened when I put the 240 in so I instictively thought it was the problem. Now I got it all sorted out and the gyro is amazing! So much more fun to fly now

Hey I know that the gyro is bad its funny how every one thinks its you all I had asked is what the voltage was and all I got was your set up is not correct and now in the main chatroom they are saying that you cant check the volts from the signal wire with a volt meter they are dead wrong as you and me both know..... I knowk they just wanted to help but all they did was make up stuff to throw me off the trail so thank tabbytabb....

Youngblood,
I assume you are young, or you probably wouldn't have an attitude like this. You may get one or two bad answers on any BB, but when everyone starts implying that you are wrong, you might want to listen. What comes out of the signal wire of the gyro is a pulse, and modern digital voltmeters will all respond differently when measuring a pulsed waveform, so your initial question cannot be answered. If you try three different digital meters on the signal line, you will get three different readings. The average voltage on the signal line should be around 0.8volts. If you read 4.30, you are probably measuring the peak voltage, and not the average. Any peak voltage between 3 and 5 volts is OK. If you were not talking about the signal wire, the question is even more off base. The power and ground wires simply pass thru the gyro, so that the voltage on the output should equal the voltage on the input.

Your gyro may be bad, but I doubt it. Measuring the voltage on the signal wire with a digital meter tells you absolutely nothing about the condition of your gyro. The best advice was given by wildstallionuk, when he said to unplug the tail ESC from the gyro and plug it directly into the receiver.

YES I know you guys are right about the pulse signal from the signal wire BUT in my case this way works for me I have checked all of the Ideas you guys gave me I have pluged my servo into my gyro also I have pluged my Phonix10 into my gyro both work but are slow to respond to comands the servos work great when the are plugged into the receiver same with the phonix 10 and the receiver reads 4.60v and higher my wattage 2amp works on my receiver also my gws works only on my receiver this tells me that if the volts are at that level it will work.... I have several gyros and all are at this level So like I said until I understand how to do it your way I will keep to my own so thanks for the ideas and when I get my gyro back i will know if this method is not working for me..and I am young 24

If you already knew all the answers, why did you even bother posting the question and wasting all our time. I have been an Electrical Design Engineer for 35 years, and I and about a dozen others tried telling you that your reading on the signal line tells you absolutely nothing about the functionality of your gyro, but you choose to ignore that. So be it.
