Hello everyone. After many tests and various tests, I start to think that my Micro Spirit Unit is not working well. I wrote some posts where I had problems with radio signal loss, and problems with servo, solved by changing servo and ESC. I had sh0257 savox that did not work well on microspirit (jitter). With tomas' advice I bought the cyclic ds92a and a new hobbywing 40a platinium v4 controller, which solved all the problems, radio signal loss, and jitter of the servos. I now have another problem,
I have the pitch servo that remains stationary after initialization, as if it were off . I installed on my trex 250 two units at the same time, in order to connect only the cables to understand the problem where it was. With my bitter surprise I discover that it is the micro spirit unit that gives me this problem, in fact my Spirit pro that I had mounted on another heli, disassembled to do this exclusion test and mounted simultaneously on my trex 250 does not give me these problems.
From the picture as you can see I mounted the landing skid of the trex 500 on a trex 250 dfc and two units, to make sure you have fast connections without disassembling all over again just for testing, to stay on the same configuration, servos, regulator etc etc,
In the end I also suspected that the cables were jst and I tried to change many, both the original unit and other good quality bought by me, but I have not solved the problem, in the picture you can see the jst cables that I changed. Now I do not know what to think, if they are JST cables that are only suitable for passing the "signals" but not large currents, or there is something in the unit that does not go.I am convinced that there is something in the unit that does not work well.
I repeat now the problem that I have on the micro spirit is the dish that remains wrong, and a servo does not work, and I speak of a new servo, that of the pitch, ds92a with a week of life.
Then magically as soon as I change units everything works fine. I've also tried to invert the pitch and aile cables, but the problem always remains on the same channel as the pitch.
The working frequency of the servos has been set to 333 mhz as in the serviceability table, and to 6 volts, so nothing wrong with their configuration, and the other parameters of the spirit all by default.
Summarizing the problem is only the pitch servo, which remains stationary as off after initialization, so it is not possible to use heli.
Changing Units from Spirit Micro to Spirit pro all disappears and works well.
How can I solve?
Thanks
