How To Build the Mini QBiT: Step by Step Build Tutorial | From parts to flying!

An in depth tutorial on how to build the Mini QBiT: a RC VTOL winged tail-sitter and a first in its class.
I’ve stopped selling the kits, thank you to all who bought one and for the interest in this project! New things to come…

I am no longer selling the Mini QBiT, thank you for your generous support!

You should be able to set a 90 degree fpv camera angle mix in Betaflight and skip the radio mixing. It does the same thing.

Very cool man, I've got a quad that's perfect for a frame swap to this. The mixing is just ingenious, would of never thought of that.

[peterryseck]

I would also recommend turning off airmode if you’re having issues which can be found in the modes tab.

[DCResinSmoker]

One thing you may want to consider adding is motor filtering. Makes a huge difference in the smoothness and response of all the rotorcraft I fly. Should be a free DL from most BL-Heli capable ESC's.

Question: I noticed on this build that the Yaw iTerm isn't being altered when switching flight modes. Thus it appears that your winged-flight is with the default I-gain values correct?

Hi
How many mini QBiT have been distributed ?

[anthonystownsend]

PS. Gal Kremer has a motor remap tool and makes it less confusing. Even after 40 or so quad builds I still hate remapping motors.

Do you make any adjustments in betaflight to deactivate I term while flying in acro mode?

[AmirRezaRezaaa-krsj]

Hiii very cool
Can i use pixhawk instead hglrc728?

[gohanmineiro]

Hey man, just letting you know that the link is broken. Also wanted to check you thoughts on scaling it

[colinmetzger]

This is awesome. Great work! I have a project that I haven't started yet where I want to build a hexacopter gyrodyne. I'm not sure yet how to make the two flight modes in Betaflight though. Basically would have the middle motors on a servo and when in forward flight, would use the other 4 props for lift, pitch and roll.

[tamuct]

Peter, I have a quick question: In forward flight I get some occasional violent rolls that invert the craft. Sometimes I'm able to recover, but several times now it's led to a crash. I don't experience any weird yaw tendencies in hover. I'm using Betaflight 4.2.9 on a GepRC F7 board. Do you have any thoughts on why this is happening?

[aaronsprojectsentertainment]

What a great video. I want to build one now.

[MatthewRayFlicks]

I have been looking at VTOLs lately and I had thought this was possible with reversing yaw and roll. The FPV cam angle mix in Beta flight is a good trick. Any thoughts on how to do this with digital? I guess putting the camera on a servo would be the best, right?

[naviluminor]

Hi
Why the switch "quadcopter / airplane" is used in 3 positions ? (top / middle / bottom)
When flying in quadcopter mode, is it obligatory to use angle or horizon mode ?
Can we choose "acro" by default ?
Great job 👍
