Everything seems to work, now the build of the quad!

KK,
Is it possible to make the arming/disarming time longer to initiate, let say 5 seconds. I fear that in flight, you could arrive in a situation where you disarm!

thanks,

The very best angle I have found is the one that makes sense for you. As long as the motors are spaced 120 degrees apart on a circle, how you hold them there is whatever turns you on. I think the 120 degree arm angle came from the old days(about 2 years ago) when people started using a 120 heli mix on their transmitters and just gyros on the tri, so of course the arms had to be at 120 also to allow you to line up the gyros.

IMHO even that spacing isn't that critical. I've flown a tri where one of the motors moved on the arm about 2 inches and didn't even notice the difference. Course that could be just my flying.

I'm just going to run and put my hard hat on(camera on it of course).

Thanh, you're scaring me!

I have 940kv motors on order (mysteries) and 9x3.8 props! Am I too facing small prop, poor yaw issue? I'll be flying on the exact frame (jakub's).

Hi Bob

I'm not sure how my post could confuse someone. What you quote talks about figuring what direction the pot uses and how to get into programming mode.

My post is to tell people to not going to the programming mode when they don't want any programming mode and just want to see if their build is working & the board is seeing the RX. And the board is seeing the RX when the light is solid on.

Isn't that my post?

Thanks

Thanh

I guess it depends on how fast you expect the yaw is. I think your motor & prop choice are fine. Sorry to scare you.

i had asked kk about the arming time too and was quickly responded by kk w/ the instructions on how to do it -

i have done it and re-compiled, but this is my first time compiling - no errors or anything but i want to fly w/ unmodified kk code first just to make sure
I will surely try to do this later, first make it flying ...

hope this helps
sure!

Thanks

Thanh - i don't think you are confusing people, but the first page is a bit confusing, not written by you.

Nice! It feels very solid. Someone was asking at the beginning of this thread if KK code would work in T style tricopter. Your video is the second video that would confirm it (the first was Kaptein tiny tricopter video I believe). I guess you shot the video in a school? It reminds me of my high school

That sounds good. Thanks for the info!

Mmm, (my fault...) I had to re-read carefully KK first post to get it done! I managed to reverse the pots (max gain is now fully CW) , and i managed to reverse the roll gyro.

KK,
Is it normal that changing the pot values will affect the gyro gain AND the stick authority? My board (TH V6 Quad v4.5) will affect both! Lowering the pots to a minimum, will lower the stick authority to almost nothing!?!?

To explain why : there are very little chances that you would use no throttle at all in flight since the quad would flip right away, and then activating full yaw at the same time is even less probable, especially not for 2 long seconds... Anyway, 2 seconds with no throttle and full yaw, the quad is crashed before you had a chance to disarm the motors...

FWIW,
Bob
Yes, i can still switch to "Idle1 mode=flying mode" (increase the throttle curve above 1ms)...

I am still convinced that vibration is affecting the gyro! Your board is attached to 2 points only, and the gyro is at one not attached extreme. This will start more easily to vibrate.

Why changing the Vref, can you explain the reason for doing this, and how you did this?
