I am running the usbasp tool on Windows 8 Consumer Preview and to do so I had to deactivate the 'signed drivers' feature. I've heard rumors that later versions of Windows 8 will not let you do this so you'll probably be stuck until someone makes a signed driver for the usbasp programmer.

Nice flying! It made me kinda dizzy at one point, but otherwise I'm very impressed by your skills.

Updating from V1.3 to V1.4 does not change your settings.
Now it performs much better, it did not lose its UP direction at all, except for the special case of the toss test where the rotation rate exceeded the maximum that the gyros can handle. This will not happen during flight.

The two last clips is recovery from inverted free fall by just adding throttle from idle.
Congratulations! Nothing like a video to show how it's done.

With the props off, the left motor (M1) spins up really fast and then at and above half thr, the other two sound to spin up to the same speed?

I put the props back on and adjusted the trims so that it almost lifts off the ground level, but when doing so, the values in the receiver test are far from zero. Is there any way to re-calibrate the receiver test so that I dont have to use all the trims to get to 0?

I am using a Spektrum dx6i with ar6200 receiver on the tricopter delrin kit from fpvmanuals with ntm28-36 750kv motors.
When you've flashed 1.3 you need to select your platform. My tri servo was maxed out and that gave me a clue. 1.3 resets everything and you need to reconfigure.

This is amazing. I can't wait to try it out. Tossing quadrotors could be a new sport. Thanks for the update!

It seems like you get approx. 4 minutes of hovering out of your battery. What battery are you using?
I got very short flight times (i.e. ~3 minutes) on my Y6 with 3s2700mAh. This was rather disappointing so I converted it into a tri and got more than 8 minutes on the same battery pack.

On this video I was using a 3s2650 mAh and yes very dissapointed on the flight time but,I understand with 6 motors and 6 esc'c and the heavier frame with 6 arms...it killed the lipo very quick. On the 3s3000 mah ,I was getting like 7 min fully charge. I will try doing a parallel on 2 3s3000 and see how much flight time I can get....thanks for liking it...maybe I'll keep it...or maybe not.
Any pix on the tri ?

Let me know the results if you do a test with parallel 3s3000 mAh batteries.

Here are some pictures and a video of my tri-copter:

Excellent job ....

I'm wandering if this toss test can be done also with DJ Naza ... I did try on a little micro 6 dof RTF quad, time ago ... but the micro control board was not smart enough ... at least micro quad (30gram of quad) don't break even falling like a stone from 3 meter high ...

Wow, very impressive method to start ;-)

I just returned from a very funny indoor session with my kk2.0 quad. Most fun I had flying through a Raven shocky of a friend of me.

So awesome!

Don't forget to cross out:

1: Improve the Self-leveling.

on the To do list.
