Multiwii Configuration: BASIC SETUP

BASIC SETUP The type of multicopter: GIMBAL: this is used just to pilot a two servo camera gymbal, This is used to add camera stabilization capabilities to an already existant platform BI: this is used for a non very common aircraft platform: the bicopter, a dual tilting motor. The Bicopter stability (especially in pitch) is its weak point having just two motors. Each motor is Read More →


Quadcopter how to reduce vibrations:prop spinners VS prop savers

This is how i achieve a little more stability reducing vibrations coming from motors using prop savers. First of all: I’m using old, not-so-balanced and not to smooth motors: Wich better test field for this very purpose? an exasperatelly unstable test platform can actually demonstrate if I’m right much better than a already stable platform where, probably, our improvement would be less perceptible that on Read More →

L3G4200D Caracteristics, features, circuit schematics and datasheet

I decided to dedicate a POST to the L3G4200D gyro. This popular and low cost sensor is present on a number of multirotors IMU out there. In my case i’ve found this sensor on both models of wich is defined as GY-80 also known as “10DOF 9-axis“, a value for price imu, easy enough except for the pullup resistor needed by this imu in order Read More →

[How to]New 10DOF 9-axis Attitude Indicator L3G4200D ADXL345 HMC5883L BMP085 Module

UPDATED! for pullups resistors correct values! This post is just an update for linking my previous post about 10DOF 9-axis Attitude Indicator L3G4200D ADXL345 HMC5883L BMP085 because this is another name under wich is known.     As you may already know this is an ‘easy to install’ IMU (compared with price) and it could require the addition of two pullup resistors in order to Read More →

Multiwii MWC, Chinese 10DOF (codename GY-80) and Arduino Nano V.3: hooking and testing

Well, i just received my i2c sensors breakout board… Here it is what the Multiwii software configuration file config.h calls GY_80 or GY-80. There is no brand, no model, no serial. We know something just about single main components/chip: (Visited 18,258 times, 16 visits today)
