Y , o h , Y , o h ,Y, Try Y without servo
By kwadkenstine on Mar 21, 2022
Can a trI yaw without a servo
Its dumb its got 4 motors , why not make a kwad ?,
Tyi coptors are outdated and better performing quads win,
But in playing about with rc cars and using the quad esc for forward and reverse off a basic servo signal ie old school reversable airplane esc or blhelli s or 32 with the correct settings .
So in stort , ditch the servo and just run a esc and motor with a 3d prop on it,
Pid tuning is going to be interesting , not having to deal with the servo and all that palava should be a bonus .
But who knows it might tune out ok.
Things that will need changing
1 the yaw motor and prop i feel are in its present form way too big.
A 1407 or similar with a 3inch prop should doo.
Thats all folks

It would be possible to remove the 4th motor and use thrust vectoring via a servo & flap. This would allow the Yaw to be a lot more reactive (fast) vs having to tilt the entire motors physical / gyroscopic mass. (Can use a smaller Servo as a result)
Example: https://www.youtube.com/watch?v=fCs5FbtJlMc&ab_channel=MIAMicro-FLIGHT
Another consideration is that the rear motor is effectively providing lift for more than a 3rd of the copters weight, which will make the pitch performance rather poor. To counter this, try mounting the battery forward or sweeping the front motors back a bit. Effectively you'd want the Center of Mass just sightly ahead of the Center of Lift.
Side Note: I've build over a dozen Tricopters over the years. Quads are pretty easy by comparison.
Dude its a joke , the whole point was to totally remove the servo from the equation and yes i intended on forward mounting the battery and other heavy things, this was NOT DESIGNED , it was built ,
And about the servo flap thrust vectoring being smoother , I totally disagree , my reasoning is that quadcopters achieve stable flight through pid loop rpm management , far greater responce and accuracy than any rc servo motor can doo,
As for building stuff , I have built a few quads ,
BUT I KEEP MY YAP SHUT AND LET PEEPS DO THEIR OWN THING,
You need to take things less seriously

You're an absolute madman!! it's just crazy enough that it might work. keep us up to date with some footage

AirbladeUAV has done it again and this time they've brought long range to the 5" class! Based on the popular Transformer Mini, the new Transformer 5" Ultralight adopts a lot of the same design philosophies with larger props and more payload capacity. It can fly upwards of 20 minutes on a 4 cell Li-Ion battery pack and in ideal conditions it's got a range of over 4 to 5 miles. In this guide I'll walk..

With the release of the DJI FPV Drone cinematic FPV has become a lot more accessible, but you certainly don't want to crash a $750 drone! The QAV-CINE Freybott is a compact, lightweight cinematic FPV drone that can take a hit and keep going. It's a lot safer to fly indoors and around people. With a naked GoPro or the SMO 4k you can capture some great stabilized footage. In this guide I'll show you..
