Mikrokopter Mikrokopter Octo motors won't start

Guys and Girls, I am hoping someone can shed some light as I am at my wits end with this thing.

I have a Mk Octo (Y-arm version) that has FC2.1 and Navi 1.1. I got it RTF as a training ship before I start flying my SJ8 around. It was flying fine when I got it. I flew it into a tree, got it down and before packing it away, I tested it and it was all fine.

I broke the landing gear in the tree mishap, and since changed that out. I unplugged the receiver, checked the wiring and it was all fine so plugged it back in.

Now several weeks later, I come to fly it again and the motors won't start. I couldn't get it to accept commands for calibrations etc and finally found that the receiver setting in MK tools was for a jetti, when I have a Hitec. I then had it accepting stick inputs to do the calibrations etc, but still no motor start.

I updated all the software to the latest releases, and still no motor start. The input from the stick is working as I can see in Koptertool the changes to the levels from my stick inputs, and all the channels are assigned correctly.
I have set in koptertool to;
1) ignore magnet error on start
2) ignore no GPS lock on start
and some other setting that prevents a motor start (can't remember what it is) so that there should be nothing locking it out.

In Koptertool, I can start each motor individually and all together via the software no problem at all.
All the LED's are Green on BL-CTRL, FC, Navi, MKGPS etc, no reds anywhere.

I tried the new start procedure, both sticks down and right, no avail.


Anyone have any ideas? I'm going to put a hammer through it soon!!

 

Just a further follow up, I have checked the range for each channel, and they are all going from 0-254, which I have read is important for the throttle channel, as someone else wrote that if the gas is >0 with the stick fully down and to the right in an attempt to start motors, it won't start.

I will never ever consider MK for my Skyjib....this thing is painful!

 

Yep, all updated and calibrated, ACC, Compass all of it. All Green LED's, steady LED on the MK3GPS.
I even disconnected the Navi and GPS boards and just used the FC, still no joy.

It has me stumped!!

 

I will do the video later in the week when I get home, but in MK Tool, there are no errors on any board. Really weird...

 

Hi and thanks for the idea. I have already tried the new start procedure as noted in the first post, and still not working

 

My apologies, work has been full-on leading up to Christmas. I will try and do it over the coming days.
