Thanks.

Did you figure it out how the gyro cube comes together. Otherwise look at picture of new gyro board...Notice how each gyro is parallel to the axis it dampens. Gyro cube is put together same way - so that there is a gyro parallel to pitch, yaw and roll axis.

I have made new much smaller gyro boards that will fit inside housing from HK401 to use with the TH board I am getting from Niall. IŽll populate them tomorrow and post some photos then!

I used your mega link and found the quadroufo site. Here is the link to the props http://www.quadroufo.com/product_inf...0ii6vuajo06fs7

The way I read this, if I buy this I get one CCW and one CW prop? Am I reading this correctly?

Sounds good! I am getting the same board so, this will be perfect!

Yep, I am going to just pre solder the pads and add flux.

One observation. I have been flying V1 tricopter and 4.1 quad. I use JR X9303 and Ar6100 RX (Spektrum DSM2).

If I turn of transmitter in tricopter V1 software (signal lost) motors just turn of regardless of throttle stick position. If I do this with Quad V4.1 I am seeing very irratical behavior of motors, including going full throttle....

That could potentially lead to situation where quad either just flies up and away and eventually crashes out of control and with all four props going at full RPM....and potentially not only just hitting someone but also carving the flesh out of their bodies.....

I would much prefer in the event of signal lost, that all motors goes to zero throttle and craft just "drops out of the sky". That seems much safer and manageable to me!

So did you build failsafe into the tri software that can explain the difference in behavior? Is this included in new 4.2 quad version?
No, there is no failsafe into any of the software versions. The RX's failsafe would override my failsafe, since they still output a valid PPM signal when signal is lost.

I think you have different failsafe settings on those RX'es

For RX'es without failsafe (the old FM system), counting illegal PPM pulses (less than 1mS or more than 2mS) and have it to shut down if there is more than a certain amount in a given time period, would be possible. But where to set the limit? Having it to shut down and fall out of the sky due to a few glithces is no fun. And having a large limit would cause a long delay before it shuts down and it probably would have hit the ground or mauled one's face already.

People who is concerned about safety should only use a radio link with error checking (FASST, DSM2 and probably some other) and properly set failsafes. They should also use heli program with a trottle cut switch or airplane program with a mixed in throttle cut switch and only turn it off when ready to lift off.

And finally remove the propellers when programming the chip ot testing new set ups.

But as they say, "st happens".....

I can hardly read the main page. The background is black and the letters are gray. The letters should have more contrast to the background, and if you can, make the background not so dark. It's much more friendlier when it is bright.

OK I changed the text to white instead as changing the background and all the images would have been a real mission.

Looking good.

Is it asking too much to have an old version firmware archive and revision notes?

Hehe... I still have some TH PCB left if you need one, PM me.

I will put up a shop in due course where KKmulticopter fans can put up their completed units for sale if they want. Like a classifieds kind of thing.

Please chip in with constructive criticism so we can make this the best multicopter site on the net.

I will work on an old firmware repository.

Cheers,

Niall
