Arducopter with Xaircraft X650 value frame
I've been looking around for a cool frame and came across the X650 V4 frame from Xaircraft.
Before I ordered it from BDpowers I did some homework concerning were I would put all the hardware.
The frame has space for the ESC's just next to the motors so I wanted to be certain that my ESC's would fit. I managed to putin them in the tight space but using the X650 ESC covers wasn't possible. Putteing the ESC's under the props keep them very cool. Also the distance between motor and ESC is kept to aminimum. EMI from powerlines will also be reduced this way. I also looked at the center plate that would hold the APM and IMU. It fits nicely and all connectors are accessable. The folding arms of this frame was a bonus.
The current setup are :
KDA 20-22L
APC 10x4.7
Plush 30 A
Motor to motor is 60cm
Currently I'm doing tests with the latest v49 code and the first couple of flight (excl gps and sonar) were very promising.
I would like to upgrade to avroto motors 2814 and perhaps a bigger 11" prop.
Suggestions welcome.

what is this red switch under the main plate for?
I really hope that I'm wrong, but it looks like you want to switch the main power supply with it?!

yes, its a main power switch. What could be wrong with it?

it is a switch designed for about 1A
a quad in this size needs about 50A peak, well you can imagine what could happen ;)

Nice, one question do the motor fixing holes line up without tweaking?
Could post a photo of this? Thnxs.

Its rated at 10A 220V and 15A 120V.
It should be good for just hovering. (testing purposes at the moment)
But probably need to get an ever higher value.
Thx

Isojed, yes they line up nicely. 19 and 16mm.
I did have to trim themounting plate a bit so that the ESC's could fit.

Great looking clean build! RE the switch. I would change that out or better totally dump it now before you even fly it. Even at hover it will likely pull 15-20amps or so.

Thx, in this stage it is stilla test setup. Cables willbe replaced once I sort out all the ideal HW positions.

even if it's rated 15A, its still about 4 times too small ;)

A bigger switch is probably a good idea. But, switches are rated at the current that they can switch, not the current that they can carry. It is the heat of the arc when they switch under load that messes stuff up. Can melt the contacts and lock "ON." Also, in the case of high voltage DC, the potential difference across the contacts may cause electrostatic attraction and it is possible that the mechanism can't pull the contacts apart. (More likely in a relay than a switch.) In such cases, AC is safer than DC.
So...Always have motors shut down when switching that thing. And find a bigger one.
