KINGKONG TINY7 - 75mm whoop
#1
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 -
https://goo.gl/pk5nOJ



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 the blade of a brushless whoop.

(The magnifying glass is in the wrong place, I'm trying to show you the AOA {Angle Of Attack} of the props!)


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. Im not too sure if the little piggy curly tail is is the antenna for the RX or VTX though?

Stuart..? BUDDY!!


On the RX side of things, the Tiny7 has the following options -
Receiver:
AC800(Frsky D8R, Frsky:X9D X9E X12S)
FM800(Futaba Fasst)
FS PPM(Flysky FS-RX2A : FS -I6, FS-I6X, FS-I6S,
FS-TM8, FS-TM10, FS-I10)
DSM2(DSM2)

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 tend to 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.

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..!

Ah yes if one opens ones eyes, scrolls to the bottom of any intoFPV page one will find the toggle for the full site and the mobile version.

Thanks Oscar, I will write a proper review once I have it, that write up I will give you to upload to your blog if you like it... With Drone Of Prey's how to hack the Eachine pro DVR onto the goggles 2 I will be able to finally upload some FPV footage soon too  Big Grin

I love these 75mm quads. They are soo much fun. The frames are almost indestructible!

I crashed mine basically as hard as it could be crashed... Repeatedly, and succeeded in breaking it, after about 3 weeks but I was flying outside into trees, walls . It picked up sand in one of the motors on day 1, the FC handled it well and it was still pretty quick even being hampered by this.

Replacement's are dirt cheap too, motors from myRCmart.com are $1.50 each (sold in pairs) and I will confirm soon that the Cheerson CX-95S  chassis is a compatible replacement for the AIO board, at $1.14 from hobbyking, (same price as replacement props) and $1.71 for the canopy this little guy should keep you (and she-who-controls-the-purse-strings) smiling all through winter!

Hi guys, I got the standard tiny 7 but has only 1x battery, Anyone sourced spare batteries for this model? please share and thanks!

Hey eCloud, sorry it has taken so long to respond to this question but I just received my replacement motors, and cheerson CX95S chassis, canopy and props, as well as some Turnigy Nanotech 600mAh and some Turnigy Graphene 600 mAh batteries on Monday,

The Graphenes come in with flight times (at a hover) at about 6 mins. I will update this post later today with the flight times from the Nanotech's...

The CX95S chassis does take the Tiny7 board but it does need some slight modification to use the 600mAh batteries. The chassis has plates to stop batteries from sliding out of the bay, these are too close to one another for these 600 mAh batteries to fit, so I snipped off these plates, but left enough to not effect the structural integrity of the frame. The new canopy also needs to be adjusted, there is a hole at the rear to screw the canopy down, the shaft that holds the screw is too long to fit the tiny 7 RX underneath, so i snipped this too, I used the shaft to expose the RX antenna.

The camera for the Tiny7 is bigger than the cheerson too, so this doesn't fit in the canopy very comfortably, I just used hot glue to mount the camera inside, due to the size difference of the camera the front of the canopy doesn't sit flush with the chassis, but this actually improves the camera angle keeping most of the chssis out of view which is a great improvement over the original layout of the Tiiny7 which lost about 30% of the FPV view to the chassis.

In addition, the CX95S chassis is slightly larger than the tiny7, this gives maybe 0.5mm more clearance between the props and ducts, this seems to have less impact from prop wash, than the original chassis. The chassis is lighter (I think, I will weigh and confirm later) and uses thinner plastic than the Tiny7, I ordered 4 replacement chassis's and all of them are slightly warped, this seems to cause more problems when using auto level modes than acro though.

Thanks Tom for the update, much appreciated! So the 600mAh will slide into the original holder of the tiny7 and have similar dimensions(1s1p?!), also the jst vs the pico (micro jst) might be an issue?
Yeah i am working out a way to raise or tilt up the camera a bit as it does block some of the view and i dont want to cut away pieces for rigidity.

Yes they will fit in the Tiny7 battery bay, but after more testing I cant really advise using the 600mAh, they are just too heavy to get enough power to recover from flips and rolls, I bought these more for my Bat-100 but I busted one of the motors when flying new battery number 2 Doh

People are saying that these 450mAh Gaoneneg batteries improve the performance of the Tiny7 but I can't say from experience. Despite these being the upgraded batteries that ship with the Tiny7 these have LOSI connectors, so still struggling with plug compatibility...

One thing I can say is that the cheerson chassis is much less durable than the stock tiny7, already broken 2 or 3 of the struts after 2 days of use, I do use my quads pretty hard though...
