$20.00. You can get cheaper ones from HobbyKing but you should use a switcher, they are way
more efficient. You do not need to cut or remove the ESC's power wires, they don't do anything.
8. You do not need to balance or tune the ESCs as shown on the Wiki (in fact you can't they are
not programmable).
9. I recommend O-ring suspension mounting of the APM board between 4 standoffs secured at the
ends of the long thin slots at the front and back of the top DJI board (assuming you put it in as I
described in (2.) above.) Put a machine screw in the top of each standoff and suspend the APM
board between them by putting a thin O-ring through each APM corner hole and passing the 2
loops over the top of the screw in each standoff. Size the O-rings so there is little or no APM
board movement, they will still provide good vibration isolation. Too much free movement and
they will cause handling lag. If you prefer you can mount a fiberglass or plastic board to the
standoffs instead and Velcro or double side foam tape the APM board to it. I like the suspension
method best though.
10. DJI supplies 2 sets of props, I recommend that for a 3 cell battery you use the longer 10" ones,
Only DJI props will fit the self locking oval shaft of the motor unless you do what I did below. The
shorter 8" props are for 4 cell use.
11. I didn't like the DJI props although they worked OK. They are light, flexible and noisy and would
break easily. So I bored out some very nice GemFan 11" x 4.5 props that I was previously using
on my KK to fit the outer diameter of the oval part of the motor shaft (about .31") and because of
a thinner hub section I also had to add a washer under each prop. This is a very highly
recommended modification; they are quieter, more efficient and will not break at the
first unpleasant encounter. These are not the expensive carbon fiber GemFans but the $2.50
carbon filled ones and they are still great. However looking at Innov8tive's web site I see they
now have a 10" x 4.5 version of this prop already hubbed correctly for the DJI FlameWheel
motors. Buy these, they are a no brainer. My guess is if you use the stock ones you'll need new
props soon anyway.
12. When starting the FlameWheel, it arms as per normal (throttle down and to the right) but if you
do not spin the props within 10 seconds or so, the DJI Opto ESCs will shut down and you will
need to disarm (down and to the left) and then rearm again. Anytime you are on the ground
longer than 10 seconds without turning the props you will need to rearm. This is not a big deal.
You will quickly get used to it and given the capability of these things to shred flesh you will
probably come to appreciate it as a worthwhile safety measure.
13. When you are setting up your board with only the USB connected, the ESCs beep continuously,
ignore them.
14. When you turn your transmitter on and plug in the FlameWheel's battery, the ESCs should emit
a short musical series and be quiet. You are then ready to arm and fly.
I have only covered substantial differences for the DJI F450 FlameWheel from the normal
Quadcopter setup procedure which is also found in the Arducopter Wiki under "Printable PDF
Guides" and is listed as "Guide for the Installation and Setup of the APM2 in a Quadcopter".
I highly recommend the FlameWheel 450, it flies quite well with standard PIDs but I have changed
mine as follows: Angular Rate P = .145, Angular Rate I = .030 and Stabilize P = 4.0.
A friend has achieved very stable flight with a FlameWheel F550 Hexacopter with RC-Tigre motors
and Graupner props following these procedures with such adaptations as are necessary with a Hex.
