Default EK2-0704B Gyro manual

After emailing E-sky, they finally put the manual to the 0704B gyro up on their website. So for anyone that has a Belt CP V2, jump over there and grab it if you want a little bit more info on your gyro. It's at least more than what's in the manual that comes with the heli.

Nice job in getting them to do that. I don't need the info myself but I know many people have asked for it in the past.

I wonder why they have packaged it as a compressed file format. The size diference between the compressed and uncompressed version is only 7K, which amounts to about a 0.3% saving on the original file size. I think this is a fairly typical result when compressing pdf documents.

If it helps anyone that cannot decompress rar files here is a link to the pdf itself which I have uploaded to the freak.

Thank you guys, one of the positive experiences that I can take forward after having belt cp V2 is coming across this forum with so much information and helpful suggestions.

Hi,

I bought one EK2-0704B gyro and I'm trying to use it on 4-channel transmitter. How I put it to head lock mode without gain channel???


Thanks,

Evandro

Thanks for posting the link.

The manual is unclear whether the pot is for gain or for delay. It seems to me that these are two separate controls, right? If the gyro extra signal line is plugged in, is the pot entirely ignored?

The link you posted actually includes the information you require, especially if you use this in conjunction with the link to the manual, posted further up. Maybe to summarise though, and to remove some of the Chinglish, here is my understanding of what it is trying to say.

The gyro will work as a rate gyro or as an HH gyro. To select HH mode you must set the gain (In eSky speak, "delay") to a value higher than 50%, lower than this and it will be in rate mode. (This is typical for many gyros.) You can modify the gain/delay value in two ways. If you only have a four channel receiver you must use the pot on the gyro itself. If you have more channels you can assign a spare channel to control the gain/delay on the gyro by connecting the gain signal wire to your receiver. Configure your transmitter to send a gain value of your choosing to the gyro and it will operate in either mode, dependant upon the value being sent. In this mode the pots, or crusts (again eSky speak), are almost always rendered totally redundant.

So, to set HH mode on this gyro, with a 4CH receiver, twiddle the pot past half way and adjust until you are happy with the tail behaviour. The standard way to go about this is to set it high, which usually causes the tail to wag, or hunt, for the correct hold position. You need the highest position possible without hunting, so when you get wag on the tail simply lower the gain/delay, a little at a time, until you do not.

I hope this helps.

Cheers

Does this gyro supports Analog and Digital servos?

Thanks,
Rico

Rico,

The Belt CP V2 comes with E-sky digital servos and this gyro, so it works with them at least. I've also used it with SG90s.

It supports them but doesn't do anything special with them. They'll be an improvement since digital servos react faster and hold better, but it's not designed with them in mind.

You can use digital servos on any gyro without problem.

What you can't do is use an analog servo on a gyro with a digital mode set to DIGITAL. You'll burn out your analog servo if you do.

Thanks everyone, for your responses.

So, is my understanding correct that: This gyro is primarily designed for Analog servo and that there is no special switch (like other gyros) for a digital servo?

Thanks again... I appreciate your help.
Rico.

Yup, that's right.

No digital switch on the gyro.

A digital servo will be faster and hold better, but that's on account of it being digital and not any result of the gyro.
