It’s finally done! The 27 minute long BabyTricopter build video.
I think I covered most things. Please let me know if I forgot something.
Good luck on your build!

Great Tricopter and great flight performance at the end of the video. I like both very much. š
Would you mind telling how your settings differ from the default settings?
Bumped up the yaw rate to 1 and reduced the yaw expo a bit. Also lowered the P gain a tad on tilt and roll. Will post settings as soon as I’ve got some that I’m 100% happy with š
Thank you David! Love the jokes. Did you get a new pointer finger??? š
Will you be offering the awesome hot glue lined heat shrink and the self-vulcanizing tape in the store at some point?
Thanks again. Great design and very inspirational flying!
Just found the heat-shrink on the store š
Thanks!
Yes a thumbs up felt like a good addition to the family š
Heat shrink yes. Already on the store. The Vulcanising tape – No, haven’t found a good one that isn’t expensive as heck. They do last a long time though as you stretch it š A roll looks small but lasts.
David, could you recommend some Self-fusing tape for starters? I’ve found some on Ebay but it does not look quality stuff.

LOL, Ordered mine as soon as it went live, and just finished building it yesterday. Figures you would post the video just after I finished mine. Flies amazing, really like it. The version of triflight I got on my board doesn’t allow BlHeli pass-through, later versions do. Also why the F3 controller, and SPI gyro if triflight doesn’t allow faster than 1K looptime? You went through the trouble of using F3, and SPI interface on a 6050 so that 8K gyro and 8K PID loop can be supported, when will it be supported by triflight or am I missing something?
Oh and you say on your video that the tail tilt doesn’t have a guide for level. If you remove the motor screws it fits perfectly in the area between the frame and the screw area, when it’s level, I figured you did that on purpose, but maybe it’s a happy coincidence.
Cool! I had no idea š
There is a lot of math going that takes time. The virtual motor and servo models use quite a bit. Not sure if we can get lower loop times than 1000 as the math is now. The stock cleanflight/betaflight will be able to run the 8k loop time though
2k is possible when accelerometer is disabled. This means no autolevel flight modes.
There’s room for optimization in the code.
I would really like a 2K option with accelerometer disabled. There is quite a significant stick feel increase from 1K to 2K but and after that it gets a little better, but it’s not super noticeable. 1K no matter how well it’s tuned, it never really feels dialed in and locked.
You can do that by entering in CLI:
set acc_hardware = 1
set gyro_lpf = OFF
set gyro_sync_denom = 4
save
Not sure if all of the commands are correct, just out of my memory.
Almost correct, setting the gyro_sync_denom=4 sets the gyro to 4X the looptime effectively 0.25K. Really just need to not be locked out of the looptime below 1000, or allowed to enter a denom of 0.5
Keeewwwl trying that š
Nice video David! I always love watching these. Looking back on it, you must have had a CRAZY busy year so far! V4, both F3FCs, baby tri, etc. I hope that with the summer ending you finally get yourself some rest. You’re the man David!
Yeah it’s been a crazy year š No rest though I have stuff to do š
What exactly are you so busy with? Don’t you just sit around all day doing nothing?
Oh, wait… I, uh, I think you mentioned something about running… what was it, a s-store? Yes, yes, a store.
Is that, like, where you have to perform QC inspections all the time, ship out orders at breakneck speed, and make constant arrangements with manufacturers and suppliers, that kind of thing??? Hmmm… that doesn’t sound like a lot at all, not at all…
I’m teasing you, of course ?. It really is crazy how much stuff you’ve got going on. Thanks for everything that you do (well, maybe not so much for blowing up R/C stuff LOL)!!!
That question mark after “Iām teasing you, of course” was supposed to be a smilie. Don’t know why it got messed up. Sorry…
Something like that yes š
Already have a F3FC Racing and Baby PDB in a Trifecta. Just ordered the Baby Tricopter kit to move it all over to. Really looking forward to the stronger frame, more nimble, and better performance coming my way! Maybe I can use it to chase my buddy flying my FT Viggen…. š
Cheers!

I have just completed my build, however, BLHelli passthrough wont work, is this the norm with these boards?
It should work. Did you flash the latest firmware? https://github.com/lkaino/Triflight/releases/download/0.5/triflight_0_5_F3FC.hex
David,
THANK YOU. And @$Ā„? you. I’d successfully gone through the 12 step process of quitting RC (Nitro, NiCd zagis, then 2M Gliders, then DLG) almost 15 years ago when I stumbled onto you and then your work on Flitetest (thank you for them too, I’m an Ohio Native). Here I am juggling grandbabies at the park thinking I wish I had my Mini Tri. I don’t fly much, a dozen packs a month, but because of you I have 4 multis now. I don’t need four. Yet here I am at my build table putting together my Baby. THANK YOU. @$Ā„? you.
lauka,
I don’t know your relationship with MrLet’sCrash, but THANK YOU AS WELL. I hope he pays you royalties.
I enjoyed this comment š
Hi all,
Im running the mini FC on a quad with BetaFlight and i noticed setting both GYRO and PID to 8k (acc /baro/mag off) my cpu load hits 90/100% which is obviously no good.
Im flying bare acro – no LED or any of that stuff – shouldnt i be able to run 8k/8k/32k given the power of this board ?
I ordered this first day but just getting to the build. Really nice. I didn’t get any heat shrink though. Perhaps that was added later.
Why do you switch motor wires to reverse the motor in all of your builds? Why not just reverse the esc with blheli? Is that less desirable?
Hi David, awesome build video. Love the jokes, and the pointer. What battery do you recommend for the Babytri?
G’day David
I would like to thank you very much for all the help with the Fc problem I had with my baby tri, I have finally got my baby tri together and flying and Dam DAM DAM with no trail tune no PID tuning I had the pleasure of popping it up into the air and it was sweet pure pleasure it did everything thing I asked it to
David thank you for such a finally finished piece of gear now it has a place on my fight bag and it’s not there, there is no leaving to go flying
~( NOW IF THERE SOMEONE THINKING ABOUT It “I MIGHT BUYONE BUT IM NOT SURE DONT CUT CORNERS JUST BUY IT IT IS THE BEST FLYING MUTLICOPTOR (( quad, tricopter, hex, octo)) IVE EVER FLOWN DONT MESS WITH ANYTHING ELSE, JUST BUY A BABY TRI” FROM RC EXPLORER
Thank s again David keep up this great work Artur??????????
Glad you like it Artii š Keep flying
