Installed a Swift 2 on one of my quads and its AWESOME! Video quality feels twice as good. Thanks guys!
| FPV Radio Questions |

Two further questions if I may.
1) Does it harm the receiver or transmitter if I power it on and have not screwed in any antennas.
Will it overheat etc.?
2) My goggles have a mushroom antenna and a panel antenna, if I cover the mushroom antenna with a large chunk of tin foil to temporarily negate its power, will the unit be harmed?
I am trying to gauge the effectiveness of the panel antenna.
| Panel Antenna Direction |

With my FPV goggles, I got two antennae: a mushroom antenna and a flat square one.
The flat square one is referred to in the goggle’s literature as a panel ( not patch ) antenna.
There is virtually NO writing or label on either side.
BUT there is a faint outline of four small squares with what appears to be wiring between each square and the main pole.
The opposite side is just plain flat material.
So the question is : which side is the active side which I point toward the vehicle?
I cannot find an answer anywhere on the web.
I do realize that it is very directional in the “facing” direction with little or no signal on the edges.
| PID values: same quad, different FC |

Can PID values interchange between different FC's tuned on the same quad?
I'm building a new mini-quad on a PixRacer (arducopter) and it is nearly identical to another one I previously built and tuned with a mini Revolution (dRonin). The frame is the superlight Diatone Blade 180.
The revo dronin build is 'Autotuned' and flies great with near zero effort. I'm kind of spoiled because I have no experience manually tuning PID's. Thus I want to just transfer the values over to the new pixracer arducopter build. If anything, just for a good starting point.
btw, arducopter's autotune is very intense, long duration requiring more than one full charge batt, large space, and is said not to work well with mini-quads. dRonin's autotune is a 75-sec process and I've done quite a few new quad tunes, up to 280mm in my living room.
Does PID values have some inherant dependancies like gyro/sampling rates, making them not interchangable? Another thought I have may be, the PID's can be transferable in similar flight stacks architecture in the same family (dRonin is from same TauLabs/OpenPilot/LibrePilot/cleanFlight/etc), but may not be compatiable with dramatically different flight stacks (like arducopter/px4/etc).
| KINGKONG TINY7 - 75mm whoop |

Thanks to Sandra and BangGood for offering this item in return for a writing a pre release article.
Coming soon, to the airspace in a room near you... (If you live near me that is!)
The KINGKONG TINY7!
Purchase from BangGood here -
The Tiny7 is the newest in quite a long line of brushed micro FPV quadcopters but I don't think its going to stay at the back of the line for long. There are a lot of tinywhoop's around, from guys who modded the original 'inductrix,' those later who added FPV to the Eachine E010 and others who went all out with the carbon fiber and aluminium upgraded chassis from RakonHeli. All these micro-quads used small 6x15mm brushed motors to drive them, this is where the KINGKONG TINY7 differs from the rest...
Yes it 'looks' like just another one of those tinywhoop's, but on paper at least, there isn't the least bit 'whoops' about it! Look closely and you will see the chassis is 1cm larger than 'your average whoop' but that allows for larger 7x20mm motors to drive more torque hungry, 40mm tri-blade props. If your still looking closely you can see that the props look pretty aggressive, with a high angle of attack, almost like a brushless whoop.
The camera on board the Tiny7 has more than the usual 600 TVL boasted by most older tinywhoop's, more even than the 700 TVL 110° FOV on the Eachine wizard X220 which is 3 times the size! No less than an 800TVL and 150° FOV camera feed being transmitted through a 25mW 16 channel VTX.
On the RX side of things, the Tiny7 has the following options -
AC800(Frsky D8R, Frsky:X9D X9E X12S)
FS PPM(Flysky FS-RX2A : FS -I6, FS-I6X, FS-I6S,
FS-TM8, FS-TM10, FS-I10)
The KINGKONG TINY7 is quite heavy at 44 grams, all up weight, compared to the 26g advertised by the 'E010s' stats. The 75mm chassis has additional support over and above the original form factor of the inductrix frame, with additional cross supports between the prop shrouds. The added resilience may well be necessary if the 720 motors are able to propel those 44 grams as quickly as I hope. Remember that 12 of those 44 grams are the battery though, and while we are on the subject...
The batteries are 1s 500mAh with a 30c discharge rate, (photographed with 'PeakPower' battery) even smaller Whoop's prefer a larger (~45c) discharge rate than this so I hope there is enough punch to deal with its heft...? I have confidence that KINGKONG know how to make good props to take full advantage of the bigger 720 motors though.
This hardware has all been backed up by an SP Racing F3 brushed FC running betaflight 3.0.1.
Edit to add : it also comes in 4 cool colours with matching props, if you get the advanced version you get all 4 different colour canopies and 16 props (4 sets in 4 colours) as well as 5 batteries and a 5 port charger.
I have to say I am really looking forward to getting this in the air..!
