Very high TRAVEL ADJ on Spektrum DX6i with Cleanflight 1.9.0 on Naze32

[pungbjoern]

I have this "issue" where I have to push my travel adjustment on my sticks almost to max (~120% out of max 125%) to get them up to 2000 and down to 1000. Am I doing something wrong? Should I be tweaking this somewhere else? It flies well even without these settings, in theory, but I've never been able to push out of the angle part of horizon mode before. I haven't been able to do flips, so I figured it was because it didn't get all the way to 2000. I haven't had a chance to test this hypothesis, but I wanted to check with you guys first. I have this for all the primary channels

Is it unexpected to have such a high travel adjustment?
Is it detrimental in any way?
Is there somewhere else I could change it?

This is actually standard for a spektrum radio, you're doing it exactly right

Where you'll notice the difference is when you get into acro stuff and start doing flips/rolls/etc, as with the end points set correctly... it goes to 11

That's good to know =)
I tried to get as close to 1000 and 2000 as I could. Are there advantages or disadvantages to over- or under-shooting? E.g. ending up at 1999 or 2001 and 999 and 1001. Should I prefer to be "inside" the range (1001 and 1999) or "outside" (999 and 2001) or a mix?

naah you're good. the only outside you need to be in right now is meatspace, flying it

10 propellers lost. No significant difference in feel. I did manage to get it to tip over sufficiently to enter into a flip from horizon mode, so I guess it worked. That said, I didn't manage to complete a whole flip, and I lost 3 propellers in the process...

Do you have any dual rates dialed in on your radio? that could prevent you from going all around in a flip... if not perhaps you have to up your roll/pitch rates in Cleanflight. That is if your machine is not underpowered or anything...

Otherwise in Horizon I just go full stick and it flips fine... you have to hold it though until it passes 180°....

 

[narcolepticltd]

Pungbjoern, go ahead and post your set up (frame, motor/prop, battery, etc) here as well as your current PID controller r/p/y rates/gains and we'll see if we can help a little on the tune department.

Breaking props means you're making progress

I'm actually calling this a success. The fact that it didn't go all the way around is attributable to me not knowing how to flip this frame. I can do it perfectly fine on a Blade Nano QX. Previously it would slam to a halt at 90° and fall down. That I got it much further than that is a success in my book. I've been watching some videos. As soon as I get a new frame (broke two arms on my second outing today) I'll nail it. Apparently I haven't been giving it enough throttle...

Here's my setup:
Frame: HobbyKing 250 color (I love this thing!)
Motor/ESC: 2206 Baby Beast Motor and 12A Afro ESC
Propellers: Gemfan or Diatone 5030

I've removed some stuff like LED and GPS/NAV things from this to make it a bit more readable.

For reference, this is how it broke: http://imgur.com/a/0DAks

Interestingly the decimal points on the stuff in the dump are WAY off.
Says: "set i_pitch = 30". Is actually: 0.030
I don't know if this is expected.

the way it displays in the GUI compared to the CLI is different. When in doubt and looking at other's PID values, if it's text and looks like it was cut from a dump, just paste that line into the CLI.

I see those photos man that sucks bad about the frame! Right now in your dump the r/p rates are sitting at 0, with the default RC rates at .9 (90%), and this would mean a flip or roll would require a LOT of altitude to complete.

I like the table!

Regarding the r/p rates, I can't imagine setting them higher. Hell, I'd like them LOWER. I have -15% expo on both roll and pitch, as otherwise I very easy fall over on my side. I set the yaw to 0.7 when I came from base flight and this was so absurdly high that I can't imagine ever setting pitch or roll to anything higher than 0. They're twitchy enough as it is. I suppose I could set it to like 0.5 and then set -50% expo or something.

start with the RC rates at 1.0, and use 70% expo in cleanflight (do not use any expo on your transmitter). At that point you can start to inch the r/p/y rates up to taste

rc rates and expo are on the receiver tab, r/p/y rates are on the tuning tab. Sorry to be curt, just trying to get a reply out before I head out the door... check your pm's!

 

[pungbjoern]

70% expo in cleanflight, you say. Does that translate to -30% expo on all axes on the TX? Default is 65%.
