Curios if anyone is changing their #define GPS_WP_RADIUS from the default of 200 to maintain a better pinpoint hold. I've just started attempting to tune my POS hold. Default settings work great, i just see a little more drift than I would like before it starts to recenter its location. I figured th...

ohh good to know. I wasnt aware that the gui options now disappear when not turned on in sketch.

In-Flight

What has changed with this feature now that 2.2 has been released. I noticed we now have a LOW and INVERT setting. How do these work.
Also, now that there is no AUX switch for LEDMAX, how can we toggle this?

In-Flight

Okay, so I kept increasing YAW I all the way up to .1 and it never stopped its slow turn to the left. At .1, it actually started slow a oscillation that was increasing in intensity. I had to land quick before it became unstable. I backed it back down to the default again for now. Any ideas? Roll 3.4...

I have a seemingly simple question. In BARO mode, does the quad only responds to inputs higher and lower than stick center? What if this is a very powerful quad that hovers at maybe 20% throttle. Would the stick need to be moved to the middle position (1500) when BARO is switched on to maintain a ho...

In-Flight

Also, forgot to mention that the quad still like to slowly yaw left, even with mag turned on. Would that be some sort of interference throwing off the mag sensor? When you fly acro or level turn off mag. If you have YAW drift then incresae I term for Yaw. Thanks, I'll give that a shot. I'm still a ...

So ACRO mode is now holding correctly and overall the quad performs much better. I did a few things but I'm thinking the EEPROM clear was the trick. 1) Switched to GemFan from EPP. 2) Switched to 2.2 from 2.1 3) Bought new prop adapters and made sure they were straight 4) Cleared the EEPROM prior to...

I was able to find out for my 2560 that the total eeprom size is 4096.
I'm a stickler for doing do things the correct way. Thanks for the input.
Still waiting on some parts before I can try again after wiping. Ill send an update.

In-Flight

So basically you are saying that all atmega use 512 eeprom? That can't be right.

In-Flight

Figured I would ask after looking at the clear eeprom code.
My FC has an atmega2560. Is the eeprom the same size on all chips, or can it vary?
If it varies, how to I find out what size mine is so I can modify the code to make sure it writes zeros to the entire thing?

In-Flight

Vibration most likely isn't my problem. Using these mounts.

In-Flight

Thanks. I'll give that a shot once I get my new prop adapters in.

In-Flight

So you think it was the clear eeprom code that did it? do you have a link to that code? I haven't tried it.

In-Flight

Yes, when I get it level in acro and then release sticks, it then leans forward and left again. All channels show center at 1500 in gui. Do I need to increase P to hold that level angle? I don't have a whole lot of options to change the weight around. it feels pretty even in my hands.

In-Flight

Right, that works for ACC/Level mode but what is the fix for acro/gyro mode? TX trims right?

In-Flight

Having an issue with my first build that I can't pinpoint. After plugging in on a flat surface at battery connect, and running an ACC calibration, my copter attempts to fly forward and to the left. I assume this is natural and I need to adjust for this behavior. What I don't understand is the correc...

In-Flight

Does uploading a new or modified sketch clear the eeprom causing the need to calibrate ACC and Mag again? Thanks for the help!

In-Flight

When should the various sensors be calibrated and how often? Should I be calibrating the gyro, ACC and mag before every flight or just once after the build is compete?
Also, if I have trimmed up the ACC, will an ACC calibration erase that trim?

In-Flight

Yeah that's what I did. I'm just saying that I can't tell if it was successful or not.

In-Flight

When I ran it I got some beeps but no motor rotation and it would not arm. I assume that the calibration was effective although I can't be certain that I heard any beeps that were not the normal start up beeps on my simonks.

In-Flight

I've read some posts on this function not working correctly in the past.
Is it generally accepted to use this now in 2.1+ without issues?

Working in the technology industry, I've noticed multiwii does not adhere to standard release practices. Major releases should be followed up with minor releases to fix bugs or make minor corrections that were missed with the initial release. Major releases should only be for feature updates. I thin...

In r1317, what is the difference between Horizon Mode and enabling the AcroTrainer.
In reading the descriptions of each, they would seem to do the same thing.

In-Flight

This is very off-topic, I don't have that problem. If you care to do a search, there are VTAIL threads where this has been discussed. Hardly. Valid question for 2.2. Your attitude is not appreciated. Very surprised by your rudeness. This is supposed to be a community that helps each other, not one ...

In-Flight

those who add the code love it. many are skeptical of doing this kind of modification so they don't try it or use y4 instead. The problem with the existing vtail setup is that the copter does not perform like a quad. you cannot yaw without unwanted roll. it's a whole different beast as vtail should ...

In-Flight

Any thought to optimizing VTAIL config?
A few people reporting enhanced control with VTAIL using this custom setup.

I think the lowest transmitter Spektrum offers that can receive telemetry is the DX8 (lots of people use it). No need for the DX18. I think the TM1000 comes packaged with most mid to high end Spektrum receivers. The TM1100 doesn't have an X-BUS port so I don't think that particular unit would be an ...

In-Flight

I was unable to find the answer to this in a search so I thought I would ask. I'm curious if any development has been done on using MultiWii to send telemetry data to a Spektrum TM1000 via its X-BUS port. This would be a great way to send existing sensor data to Spektrum transmitters without the nee...

In-Flight

if you activate GPS with ACC but without MAG, the heading control of the GPS won't be active, but the angle correction of GPS will be active So the copter will still get home but it could be facing in any direction ? Thats how I understand it. I wasn't aware until now that the GPS function didn't a...

In-Flight

we could in fact auto activate function when one is selected. for instance, it's a nonsense to activate GPS without ACC. but you have the choice of ACC mode with way Ding Ding Ding... Thats what I was thinking. Have the GUI auto-select or unselect options that are dependent on each other. (selectin...

What we really need is an updated Wiki.

In-Flight

Maybe to sum up my last post...
Are there any modes that should be used together? (A problem can arise if one mode is enabled without another)
Are there any modes that should NOT be used together? (A problem can arise by two modes fighting each other)

In-Flight

Make a chart! Us visual learners would LOVE it. I'm still trying to figure out what options are dependent on each other. IE: If i don't enable ACC with GPS Home, is there a potential for the copter to fall out of the sky? (EDIT: Or would ACC and GPS HOME actually fight each other?) ...or can most of...

In-Flight

I actually came looking for the same thing just now.

I'd like to see a chart that explains each option in 2.1 as well as list the dependencies of each if any.
