Warpquad 'Z'-Pod FPV Concept
--- More pics ---

Designed for fast forward flight, in high power FPV craft, so you can see where you're going.

Pros
- Mass is centralised as close as possible to the centre of gravity
- Centre of gravity is as close as possible to the centre of the prop disks
- FPV weight is centred on the 'Z' axis and balanced by the lipo
- Symmetric for even Pitch / Roll response and easy tuning
- Both cameras are tilted back 30 degrees
- Both cameras have prop free vision
- The camera becomes level in steady forward flight
- Ground is in the lower 1/5th of the screen, with a 2.8 lens, on take off and low hover
- Removable and transferable between frames
- Power is only connection between frame and pod
- Connected with cable ties to break free in a hard crash
- Mass dampened and isolation mounted
- Antenna's radiation pattern is level in FFF and placed well clear of obstruction
- Off the self parts
- Lightweight
- Aerodynamic - it does make a difference!!!

Cons at the moment...
It's a hack
Dubious RX placement
VTX is exposed in a crash
Pod needs improved aerodynamics
Antenna extension cable needs a double right angle (on its way)
Better suited in size to the 270mm frame at the moment
Need better lipos!

The next step is head tracking. First a single servo on pitch, working up to a 3 axis brushless gimbal More details to come...

Construction Video Series... Warpquad String Theory frame.


Carbon Finishing...

Warpquad Carbon Finishing (11 min 31 sec)


Additional notes...
- Use a fresh square of sandpaper for each part.
- Some plates are sized so the screws thread through the lower plate and then thread into the arms. The top plates are looser so they slip over the screws. If your plates are labeled top and bottom, this is the reason. It is to keep tolerances as tight for the firmest frame possible.
- There is a spare high tensile / stainless steel screw included in the fastener pack to thread through the carbon before using the alloy screws.

Also, a fifth set of smaller wires can be added to run the FC directly from the lipo distribution point to keep the voltage as clean as possible.


ESC Prep...

Arm Assembly...

Warpquad Arm Assembly (12 min 51 sec)


*** I'm now recommending heatshrinking the arm first, then following the standard procedure. This for an extra layer of insulation to protect the ESC from the carbon. *** 10mm heatshrink just fits over the arm, 12mm would be ideal.




Main Assembly...

Warpquad Main Assembly (10 min 59 sec)


Main Assembly Amendment...

At times there are top and bottom plates marked. During QC if some are tighter tolerance I make them lower plates, and the slip fitting ones tops. The lower ones require the screw to thread through. They fit nice and tight but the threads will still slip to pull up tight on the arms. The top plates are looser so they can slip over the tops of the threads in final assembly.

The arms are sized similarly. The motor screw holes are a slip fit while the frame side holes at times require the included hi tensile steel screw to thread through them first (so you don't wear out the alloy screws). This is all in an endeavour to keep the frame as tight as possible given any variables at hand.

To assemble, thread the screws through the lower plate until the ends just protrude, and then start them into the arm. Keep the gap even between the two and evenly pull in the gap as the heads reach the lower plate.

MultiWii Version 2.2 Settings...

Download Win GUI 2.2 here...
https://code.google.com/p/mw-wingui/...2.zip&can=2&q=

*** Beware, when opening my GUI file there is a bug where it will set the throttle expo to a weird figure. Make sure it is ZERO ***

*** I also add -50% expo (Spektrum DX8) on my TX YAW channel to liven up centre stick, and counteract the expo added by setting YAW RATE to 1.0 ***





MultiWii Version 2.3 Sketch and Settings...

Attached is the Sketch for a Flip Pro FC + Spektrum Sat RX at 2048 (11ms) + SimonK

- No LPF is enabled
- ESC range is stock SimonK 1064-1860
- Rotors will spin when armed
- Failsafe is 1 second wait, 1 second level, then off

-50% expo on TX YAW no longer applies! Radio setup is stock standard now. MW2.3 fixed the sluggish YAW issue.
I set the throttle channel to 1090-1980 (so avoid low end deadband) and all other channels to 1500 centre, 1020-1980 in the GUI.
With 2.2 you had to be very careful not to go outside 1000-2000 and that's just stuck with me now.


My settings so far...
**** Always use the same version of Multiwii Config as the Sketch!!! (ie MW2.3 here) *****





Final Glide's Naze Tuning...
From here... http://www.rcgroups.com/forums/showp...postcount=3966

This is for the standard build 230mm Warpquad with KISS esc's, Naze 32, SS2204 and either 1000 or 1300 3s batteries. It is also worth noting that this is with either HQ Carbon Blend or HQ Glass/Nylon 6x4.5 props. FC props may require a slightly different tune due to them being out of balance and their tracking going out of whack after a few crashes.

Although you never really stop fiddling I think I'm pretty much there. See below for the screenshots and other info...




Other setup info:
Spektrum TX Settings
Dual Rates:
Aileron + Elevator + Rudder= 115% for Spektrum (1100 - 1900 in Baseflight aprox)
I increased the dual rates on my Spektrum TX to get more stick resolution from the Naze 32. Increasing to 115% gives you aprox endpoints of 1100-1900.

Expo:
Aileron + Elevator= 40%
Rudder= 10%
Expo is a very personal thing but these settings feel just right to me.

Key Setup info
*set looptime = 2000
This is the speed at which the FC does it's calculations. I have set it to match the speed of the esc's to make use of the extra bandwidth available.
*set motor_pwm_rate = 490
This gets the esc and FC talking at the same speed.
*set tpa_breakpoint = 1300
This determines what throttle level TPA starts to kick in, which needs to be lower as the power to weight ratio increases the throttle percentage for hover lowers. Who here hasn't had those annoying oscillations just below half throttle on the WQ that they can't get rid of?!?

More coming soon...

MotoWii Flight Controller

The MotoWii board is a custom-designed and integrated MultiWii flight controller, 4S compatible switching power supply, and power distribution board that replaces the top plate of the Warpquad frame. It simplifies construction and eliminates most of the battery wiring harness.



These boards can be ordered with Warpquad kits on Soma's website here:

http://www.warpquad.com/magento/elec...otowii-fc.html

or by sending a PM to me.

Getting started with MultiWii and Arduino

The MotoWii uses the Arduino development system for editing and installing the firmware. If you're not familiar with Arduino, please see the tutorials here:

http://arduino.cc/en/Guide/HomePage#

I've made some additional notes on MultiWii configuration and installation here:

http://www.rcgroups.com/forums/showthread.php?t=2230193

Custom MultiWii Sketch

This board differs from any of the standard MultiWii boards and requires a customized version of the MultiWii code. The source code for the "sketch" for MultiWii 2.3 for MotoWii is attached. In Arduino, select "Leonardo" as the board type. These sketches are based on a snapshot of MultiWii later than 2.3 that runs the looptime faster, around 2200uS instead of 2600 in the MultiWii 2.3 release.

Change History:

V2 has the ESC calibration high throttle duration increased from 3 to 8 seconds to work with slow-starting ESCs like some versions of BLHELI.

MultiWii_MotoWii_RevB_V2

V3 has KISS 125uS Oneshot mode support selectable with #define ONESHOT. This will work on any PROMICRO target including NanoWii and Flip Pro. Oneshot mode requires shorting the 125uS option jumpers J1 on the ESCs.

V3 supports a "discovery buzzer" attached to the SPPM pins with the DISCO_BUZZER define. This is described below in detail.

V3 also has the FAILSAFE_OFF_DELAY reduced from 20 seconds to 5 seconds so the motors will stop quicker in a failsafe.

MultiWii_MotoWii_RevB_V3

Assembly and Operating instructions

Note that the bottom side of the PCB contains the power distribution circuitry. It is covered by solder mask which provides some electrical isolation, but it's highly recommended to use additional insulation between the board and the carbon-fiber Warpquad arms. A layer of electrical tape on the arms trimmed to the outline of the arms seems to work well.

Solder a lipo pigtail to the two pins at the bottom of the board. 14ga wire is recommended. Lipos up to 5S may be used. Solder the ESC + and - battery leads to the pads on each corner of the board. Observe the polarity markings on all connections. Solder the signal wire of the ESCs to the small pads between the power leads.

MotoWii connects to receivers using Spektrum satellite or PPM-SUM interfaces. The sketch is preconfigured for SPEKTRUM 2048 using the header labeled SAT. The S, G and V pins are signal, ground and Vcc (3.3V). To use PPM-SUM instead, connect to the header labeled G, V and PPM for ground, Vcc, and signal. Comment the SPEKTRUM define and uncomment the required PPM_SUM define in the sketch. (Do NOT uncomment #define PPM_ON_THROTTLE - that does not apply to this microcontroller.)

ESC Calibration

The sketches linked above support automatic ESC calibration without reloading the sketch. This requires installation of a two-pin header on the connector labeled "CAL" on the board. The ESCs are properly calibrated to the range of the MINCOMMAND to MAXTHROTTLE values in the sketch.

To perform calibration:

1) REMOVE THE PROPELLERS The calibration function sends full throttle signals to the ESCs and the potential for disaster exists unless the props are removed.

2) Install a shorting jumper on the CAL header.

3) Connect a lipo. Wait for the beeping to complete, in about ten seconds. Note: The motors will not spin during calibration.

4) Disconnect the lipo and remove the jumper. Calibration is complete.

General Radio Setup

Center all the trims on your transmitter. Use the MultiWiiConf gui and adjust the subtrims on your transmitter (i.e. in the Servo Travel menu) to get all channels centered at 1500 +/- 5. Adjust all channel endpoints to around 1950 on the high end and around 1050 on the low end, except the throttle which should be set around 1080 on the low end.

Discovery Buzzer

You can use the Hobbyking discovery buzzer on the MotoWii, NanoWii or Flip Pro with a Spektrum or Lemon satellite receiver. Plug the buzzer onto the SPPM pins on the MotoWii or the throttle (D7) pins on the other boards. It runs on the 5V on the header pins.

In the MultiWii_MotoWii_RevB_V3 sketch, uncomment #define DISCO_BUZZER to enable the buzzer on failsafe. To activate the buzzer with an AUX channel, also uncomment #define DISCO_CHANNEL and set the value to the desired channel.

If you're using a PWM receiver, you can connect the buzzer directly to an AUX channel on the receiver.

Lemon DSM2 Satellite note

At least some of the Lemon satellites were shipped with the red and yellow wires in the cable swapped. The 3.3V lead is the closest to the edge of the satellite board. This is the CORRECT wire order:

Ha!

That was Flits's first time flying in a month, first session with the copter, flying my control setup, and trying not to crash my prototype

He's a madman! Top Pilot That's him trying to take it easy!

We were all surprised how easy it is to adapt to the angled cam. It just feels right. It just doesn't hover very well.

But as a wise man said "Hovering gets you nowhere"

Thanks mate, we're all surprised how well it works.

Its different, and won't be for everyone, but for what it does it does it very well. Particularly the way it handles like an acro copter

Off to do more testing now

On a more serious note...

One of my 3S Nano-Techs shows up as a 2-cell battery when I put the voltage checker on the balance lead. Same indication when I put it on the charger. I put the DMM on the main plug and get 7.6 volts.

Can it be fixed? Can it be flown (even if as a 2S)?

Wow the fpv looks like it will be fast and furious New thread looks great too. Anyone with issues seeing the small stuff soldering as I do, I just picked this up and it is working great! You can get up to 6x magnification with it. I'm using the 2.5x while prepping my new esc to install and it is so easy to see what I'm doing now and much easier to keep solder from getting where it shouldn't. The solder tips I finally got help too. The chisel tip is much better for getting the larger wires off the esc than the single medium tip I trudged through the initial build with.

Wow, $8. Is it shipped BG slow from you-know-where? Weeks?

Seeing better would help, for sure. But stopping my hand from shaking and bouncing all over the place while I'm trying to set the iron down on that one tiny little spot is a bigger issue for me.
