Thanks, Steve - it came out pretty well, I think.

Kenneth did a great job with the design and we are considering producing this as a kit. Downside is that its pretty expensive in materials. This was just a short testhop with default settings similar to the LB frames. Flew pretty good, but needs a little bit of tuning. Thursday we will do some payload and flight time tests.

PPM input works as-is, simply use the same RC connector on the M4 board and set the radio type option to PPM. Just keep in mind there is only 3.3V on the RC + connection, so if your Rx needs more voltage, you may need to use a step-up regulator or other power source.

When is the m4 expected to be released ? I´m asking because a local video-club asked me yesterday about a very special project. I need a very small copter which i can trust, and which is able to lift a GoPro HD3 at least for 5 minutes. So i thought about the m4 at a 300 size quad oder 350 size hexa.

Is there anythign in progress about anti-collisioon sensoring with sonar / ultrasonic sensors ? Would be great for this project if able.... if there is any contact i should call directly, please let me know.

The AQ Motherboard looks awesome, can't wait for it to be released. Good job on the OSD, that's much needed for AutoQuad. There's just one thing that bothers me - at max 150A, the power distribution seems a bit underpowered. It's not uncommon for motors to draw 20A or more per motor in heavier camera rigs, so that's at least 160A in octo config. Could you guys please make the board more heavy duty? I'll surely use the motherboard in my current hexa (eats up to 120A), but the 150A max output prevents me from using it in my upcoming heavy lift octo project, which leaves me with no OSD and no reliable power distribution (and other goods that the motherboard has to offer).

On a side note - do you guys already have any pricing info about Quatos pricing for commercial use?

If 150A isn't enough you should think about your drive drain!
I.e. an MN3508 KV380 with a 15x5 prop need 14A Max. on 6S --> 112A. This will give you (a calculated) thrust of roughly 15kg.

You won't lift a RED camera on MN3508. :) I'm talking about heavy lifting rigs that have AUW of 13kg or more. For that you need at least 20A per motor in flat octo or x8 config.

o.k! U got me!
U8 KV135 with 29x9.5CF --> 28.6kg thrust @ 113A, 6S

Don't claim it's too expensive:-)
