BetaFlight 3.2 FINAL - on BetaFPV F3 OSD Whoop


#61

Glad to have found this thread! Just got this FC and built a whoop with 7x16 19kv motors. @Benedikt and others, what do you use for the following parameters:

Gyro update frequency?
PID loop frequency?
Dynamic Filtering?
PT1 filter?
Notch filters?

Used to flying 5" in acro. Many thanks!


#63

For F3 go with 4K/4K with dynamic filter on, PT1 and try both notches off. That should give the best performance assuming motors do not get too hot, check after making changes.

Hi guys,

Just finished building my first Micro, a 7x16 Tiny whoop using the Betafpv F3 OSD Frsky board.

Got it flying well so far with some tweaks of my own that I took from the 5" brushless quads that I fly. Still need to refine this and do more testing.

Here are some differences to the config pasted on this thread that I use on mine and seem to work well for me, would like to share/discuss with you.

  • All beepers off - to free up cpu cycles, not that an f3 board would need it anyway"

  • All filters off - Not needed in a good build with quality parts.
    "set dterm_lowpass_type = PT1"
    “set gyro_lpf = OFF”
    “set dterm_notch_hz = 0”

  • Acro mode enabled - Pilots choice

  • Airmode on - Pilots choice

  • Motor_stop disabled - For Airmode to work properly your props have to be spinning a little to have authority when throttle is 0"
    “feature -MOTOR_STOP”
    “set min_throttle = 1050”

  • Accel disabled - Will allow you to arm/disarm in mid flight upside down or in any position.
    “set acc_hardware = NONE”

  • Voltage reading " set vbat_scale = 113" This was a tricky one for me, for some reason my voltage reading was always off when using 110" Would like to know if this is happening to you too.

Will update after further testing.

BF 3.2.4 was released.
Relevant lines from the release note:
Added YSTTM gyro threshold (#4774);
Changed slew filter to work for all axis instead of just yaw (#4819);
Added option to check gyro overflow on yaw or all axes (#4827);

One test flight so far. Flies good, just as 3.2.3, using the exact same settings.


#66

Like to know peoples thoughts on this FC.


#67

If you are looking for bad reviews you are probably in the wrong spot. I will say that I own 3 whoops with betaflight osd compatible fc’s and the betafpv with black motors is my favorite to fly right now. Go for it!

I just purchased the upgraded inductrix fpv + frame and stock motor replacements from this website. Turns out the lack of power wasn’t due to a bad motor. It still needs over half throttle to idle even with the brand new motors. I think the board is shot so I wanted to swap to this BetaFPV board. It should fit in that frame, right?


#70

Yep, fits. Flies great, one of my favourite setups so far!

Got my whoop kit and experiencing some first time builder issues.This is my first time using a real transmitter also. I have a Taranis Q X7. I finally figured out how to get connected to my receiver using betaflight configurator and I flashed 3.3.1. I had difficulty binding and after some reading I saw that 3.3 doesn’t support the STM chip and since my computer recognizes the receiver as an STM device I reflashed to 3.2.5. I can bind and configure but now when I try to plug in to my battery instead of USB connection, the motors run and my transmitter has no control. When connected to USB, my radio binds and I see stick control as I should. I set up my receiver per the YouTube instructions and used the basic CLI instructions I found in this thread including setting up the switches for Aux1. Should I have set up something for Aux 2?

I hoping someone can help and I’m sure it’s something I missed along the way.

#72

Double check that the motors are set to brushed not one shot, I’ve had that happen before to, changed it to brushed motors in bf and it works fine


#73

Thanks @shadowdragon, you were right, it was set on one shot. I switched to brushed and that got me one step closer, Motors now don’t spin unless I move my switches to armed and then they spin at idle, but when I advance throttle to about half they then spin on up faster and I lose throttle control. I don’t have switches set up for Aux 2 on my Taranis x7 and I’m not sure how to do that or if that is the new issue.


#74

No problem glad to help a little, unfortunately I use spectrum transmitter so I’ll have to hand the rest off to someone more knowledgeable


#75

I reflashed and set up my settings again. I was having difficulty getting it to arm so I erased my switch settings and set up my Arm to a single switch instead of the two switch mix and it now works. I have a lot to learn but I did make my first FPV flight today. It’s so much different than LOS. I’ll try the two switch arm again sometime soon as I’m sure I’ll figure it out as I get more familiar with the Taranis.

Thanks for the help @shadowdragon.

Your welcome glad I could help, welcome to your new addiction, enjoy :smile:
