Hello.
I am very interested in your model. What are the dimensions of the model? There are problems on the pitch?
I built a model AT-99 Scorpion.

Hello, this is because of your famous model, I decided to build my own, thank you very much.

And yes I have a problem of stabilization of the axis of the pitch, I use a black board KK, for the dimension it measures about 60cm long and 60cm wide and 20cm high, with a weight of 700gr.

How are you going to solve this problem?
I have tried many options bicoptera and they had a problem with the pitch.
In the end I put the impeller in the tail. The result is a tricopter.

So for now, a very high center of gravity of the machine and I reduced the end point of the pitch to 20%, and the gain to a minimum ,I remake the test in the week!

for now I want a steady, within a circle of 1 meter, but it is still difficult.

After several unsuccessful trials more or less, the right end point of the pitch will remain at 25% and no show by cons it takes a lot of weight at the lowest point of the device with 85 grams more, it becomes more docile and controllable !

The downside is that if it comes from trops on this axis, it is getting difficult to catch up!

In these models, I use MultiWii.
I have not tested, but try to change the location of propellers and engines. Screws-bottom. As here. This is not my model.

What kind of gyro are you using? I have been researching and building VTOLs and it seems that a gryo that stabilizes the aircraft on all 3 axis is ideal. Just a suggestion!

A good place to start is the KK2.0 board from hobbyking, dead cheap and field programable. Make sure it's running firmware version 1.5.
