Tri Racers

What are the major flight differences between the 4 motored quads, and the 3 motored Tri Copters????

Yaw authority, lifting capabilities and any time you have an odd number of motors you need a servo under a motor to yaw.

WHO ARE YOU??? you just gotta have the biggest brain around here...you know everything.
I saw a servo under a motor, and I was wondering what the hell it was doing.
Does the lack of weight make them faster racers..or is that negated by less thrust from only 3 motors???

Haha, I started here fairly recently asking many of the same questions.

It really depends on the quadcopter, but in general they are slower racers. There are many hex racers, because motors have to produce more thrust than they add to be of use. Some of the fastest quadcopters use EDFs, they are expensive and insanely fast.

Ok...all I need to know is what the hell a EDF is

Sorry, it is a electric ducted fan, they generally have more blades with a lot higher pitch and have a shroud around them. Mostly used in place of turbines on model planes.

This guy can get his up to 100mph without even adding a tilt for the motors hahaha


A to combat the angle you have to be to go forward many have used a servo to tilt the motors forward, here is a picture of that.

Ok ...hows about units with 6 motors...a la....
and can the average controller/transmitter/gps handle this configuration...and are there any pluses to a config like this.

More thrust, less battery life (in general), and about any flight controller can handle this.

lol...thanks, I was just curios...I cant find any more weird configurations for you to review
...FOR NOW!

Hi try George on the Y6 its a tri but has 6 motors does not need the servo for Yaw

It has an even number of motors. It is actually my favorite configuration hashaha. Cheapest stacked redundancy. Thanks for mentioning it. It flys a lot like a quadcopter, but it is a little less stable, and does not have the 'whippy' yaw that a tri-copter does

A Y6 is not a tricopter.

Here's a tricopter in the hands of a good pilot on a very windy day. Nothing fancy as far as construction or materials.

Well it depends how you define it, you have three points of rotation, but 6 motors.

Hahaha, a really skillful pilot. The flight characteristics that the tail servo gives you make some things possible that just are not with other configurations.
