MultiWii

Thanks Leo.Will be very interested to see the results.

No problems.Thanks mate.

Thanks Kbev.All that sounds a bit beyond my limited experience so best if I stick to item 4.Tried the position hold and RTH today and both worked in winds up to 10 kph.In RTH mode waited till home,selected position hold and manually landed.With the limited memory of the board might be to stick with...

May be a silly question but have you put the props in their correct positions?

In the Multiwiiconf aux settings there is an option called "land".Under what conditions could that be used?I was hoping it could be used in conjunction with "return to home"if that was possible.Any advice greatly appreciated.

It won't land on a RTH. To land it has to have a land waypoint. It returns to the home position using lat. and long. and that's all. I have no idea why your 5 meter RTH is still rising to 15. I'm hoping others will help out with your problem as this is my last post here in these forums. Thanks very...

Back on the topic of GPS problems.Just tried the return to home and even though I have changed the RTH altitude to 5 it still rises to 15 metres.It now will return to home but remains at 15 metres at the home position and will not land.I have checked the config h code as best I could with my limited...

After scouring this forum for a possible answer I found somebody else on page 4 of the general discussion area experiencing the same problem. When originally programmed I used Multiwiiconf but had trouble getting it to run recently so started using wingui which without realising it was causing my pr...

As a newbie to Multiwii I need some advice on setting up the throttle on my flight controller.After setting up config h to the best of my limited ability I have found that the motors don't start to run until the throttle is at 45%.After some advice from Kbev the speed controllers were recalibrated u...

Did the esc calibration but the motors didn't spin up only the esc's beeped.throttle response didn't change.Are there any other areas of config h that would affect throttle response? If preferred I can open a new topic on throttle adjustment. That would be best. Others that know your problem can ma...

Thanks very much for the help Kbev.The areas where I undefined were the fixed wing and helicopters.Testing RTH will be at our local club field,a large flat grassy area.I shall watch the video. Just as an addition to this reply the esc's were checked for calibration individually,disconnected from the...

As you suggested Kbev5709 went through the config h and disabled a lot of the default settings plus recalibrated the mag and acc after the changes.Also checked the number of satellites on two occasions using the EZ-GUI.First 7 second 10 which would be enough for RTH.Haven't tried RTH again yet since...

Thanks kbev5709 for all the information.A lot to digest but enjoy the challenge. One quick question. Are you trying to do GPS using a 328P processor (in your flight controller?) I ask because you are using i2c. They are known to not have the memory to do GPS with any kind of reliability. I think a ...

Thanks kbev5709 for all the information.A lot to digest but enjoy the challenge.

Some of the many things that can make GPS malfunction. Did not calibrate mag before using (You should always properly calibrate the mag before any gps flight) Wrong magnetic declination in config.h Wrong GPS protocol enabled in config.h Failure to enable the waypoint define //Enables the MSP_WP com...

I am relatively new to quads.I have programmed the flight controller and initially had problems with electrical interference which has been rectified.All modes seem to function correctly until you come to GPS functions.GPS hold does not function and when GPS RTH is selected the quad rises to about 1...

Sorry,having a bit of a hard time getting the video to demonstrate my problem.The weather has not been to kind(to much wind).

Sorry, didn't mean to list the IC2 thing twice. Also check your Alt PID. The thing that made me say PIDs was you mentioned that the craft oscillates. That is a clue that the PIDs need some tuning usually. Does it oscillate up and down or in a circular fashion. Up and down will require Alt adjustmen...

Have you tuned your Alt, Pos, Pos R, and Nav R PIDs? Do you have your Magnetic declination set properly? Is your IC2 GPS enabled in Arduino Config.h sketch? Have you calibrated your mag? Do you have IC2 enabled in the GPS section of your config.h? Some things to check.... Thank you for the reply Fe...

Just completing an installation of a quad using a Multiwii SE version 2.5 using a Crius CN06 GPS and IC2 Nav board.Options I am using on one switch is acro,horizon and headfree,second switch GPS hold and go to home.Options on switch one are working.However when I select GPS hold the quad starts to o...

I think its Ublox.

If that is the flight control board you are using then from what I have been told (I am using the same setup) you need the supplied I2C board between the GPS and the flight controller for it to work.

Thanks for all the help and information Cereal Killer.My position is Latitude -33.944873 Longitude 151.007525.I have gone ahead and twisted the power cables to the ESC's.Initial checks in the backyard after doing the mod have been encouraging.Headfree and GPS hold appear to be working but will do mo...

Thanks everyone for the advice.The board type is a Crius Multiwii SE version 2.5 using a ATmega 328P micro controller,MPU6050C 6 axis gyro/accelerate,HMC5883L 3 axis digital magnetometer and a BMP085 digital air pressure sensor.The magnetic declination for the area I fly has been added to the code.I...

Being new to quads I was wondering if somebody could give me some advice on a problem.I have just installed and programmed a Multiwii se 2.5 with CN06 GPS and IC2 Nav board.Modes activated are Horizon,headfree,GPS hold and return to home through aux 1&2.When I activate headfree the quad doesn't ...
