Quadrino "Rev 1E"

Latest MultiWii Firmware

The latest version of the MultiWii is version 2.0 Pre2 (2nd Release Candidate) released on March 13th 2012. MultiWii is working up to version 2.0 and this is the second candidate to having a stable version 2.

I've personally tested this out on the Quadrino and overall this is an excellent new release! Acro (gyro) flight is noticably smoother, it reminds me of the flight of a dragonfly! It's just smooth and maneuverable!

Autolevel now contains an auto tuning feature which is enabled in this firmware. This auto-trims the autolevel during flight. Trimming your autolevel was always a bit of a pain. It wasnt a hard process once you did it a few times, but it tripped up quite a few new users to MultiWii. Now we can look forward to great auto-leveling from the get-go!

Head-Free mode (Care-free)

MultiWii version 2.0 includes a new feature called Head-free mode that is great for beginner flyers or for times when you lose orientation of the copter. Do you fly in the dark? With Head-free mode the copter essentially has no "front" and roll/pitch will react according to your perspective. So no matter the copter orientation, joystick forward is fly away, back is fly towards you, left is bank left, and right is bank right. It's that simple and it works!

To illustrate, I had just got my Gaui330 flying again and due to some twisted arms I had a nasty yaw problem. The copter was spinning like a top a full 360 degrees about every 3 seconds. Instead of compensating with yaw stick, I turned head-free mode on. I flew my spinning top without any problem. It was pitch black out and all I could see is the blue stable light yet I could still fly the copter around even with it spinning!

[notice class="attention"]If you are upgrading from MultiWii 1.9 to 2.0 your accellerometer (ACC) sensor will read crazy. This is expected due to a change in the ACC scale/calibration. Simply place the quad on the table or floor as level as possible and hit the CALIB ACC button. Two seconds later all sensor lines will read normal again. The ACC Z parameter, in case you notice, will now settle at a 256 level as opposed to the old 512 level.[/notice]

MPU6050

Some units shipped with the MPU6050 combined Gyro and Accellerometer sensor. Units with the new combo sensor will have the ACC sensor position on the board unpopulated. Bosch Sensortech has discontinued the BMA180 accellerometer with no compatible substitute so the switch to the MPU6050 was required. There is no difference between the operation of the two sensors. (The MPU6050 sensor has some stated features for pre-computing the ACC/Gyro sensor data but documentation of these features are currently withheld by the manufacturer and are thus not used by MultiWii.)
