Hey all,

It's been a while since I've posted,got a little rant and or inquiring.
So I purchased some items from banggood over a month ago,during this pandemic I was leery to do so but ebay and amazon stuff I ordered shipped ok,longer than usual but understood.
Banggood has been weird though,items show shipped,tracking numbers don't exist,but they still got paid my over $400 in orders.
I know it's a mess in the world just curious if banggood has cashed out and ran with our money.

Z3-FPV is a first person view flight controller applied on RC aircraft. The important data such as real-time altitude, speed, voltage, posture and distance can be shown on screen with the OSD function in Z3-FPV. The PMU(power management module) that supports 2-6S input can provide real-time data collection of battery voltage and current while providing stable power supply to the flight control, providing indispensable key information for FPV voyage. It can be applied on normal wing, fly-wing, and V-tail airplanes.

It supports five flying modes, when it controls the airplane flying after connected with receiver. The RTH mode can allow the aircraft to return to the take-off point safely under any circumstances. Under normal stability-enhancing mode, the stability of flight can be fully improved. Safe mode allows the aircraft to fly at a fixed altitude and directional stability. Aerobatics mode can lock the flight attitude to meet the aerobatic needs of players. Off mode (manual mode) allows the player to control the aircraft completely autonomously. And it can automatically switch back to the self-driving mode when the remote control signal is lost or out of control, allowing the aircraft to return to the take-off point safely.

Z3-FPV uses the original lever mode to enter the horizontal calibration, the triggering method is simple, no need to connect a computer, more convenient and faster

how to configure software for asymmetric aircraft ?

Halloa RC people

soooo recently I started jet another FPV quadcopter build.. In my video on the frame I posted a list of the components and quite a few people asked why I was using KO Tech motors here.. Partly probably because it is a lesser known brand (?)

The Demon Seed Cryo 2208 1900 KV's :

Dealer list:

Well guess what.. here IS why

Below are some pictures and a youtube video of my Guillow's Super Cub 95 free-flight balsa plane kit - RC conversion.

I used Horizon Hobby/E-Flite ultra micro parts for the electronics, specifically from the UMX Cessna. The plane includes working ailerons, elevator, rudder, flaps, and even a SAFE mode toggle. The flaps do make a difference, even at this size, and allows for some rather slow flight (seen in the video)! 4 servos are used.

Note: The original flight controller on the UMX Cessna is programmed for dual ailerons. I had to make a USB cable to interface with the Spectrum AS3X programming software, to change that. I changed it to support one servo on the ailerons and one servo on the flaps. I also had to tweak it to get the SAFE Select to work as well.

Final all up flying weight: 81 grams including the battery, which was a 2s 7.4v 200mAh pack.

The battery itself weighs about 13 grams. I know the covering job isn't the prettiest, but this is amazingly light for a 6 channel plane!
As a reference, the E-Flite UMX Cessna 182 is about 130 grams in weight.

6 Channels includes Ailerons, Elevator, Rudder, Throttle, Flaps, and SAFE Selection toggle- perfect to buddy box a friend on!

Round two : Using the transmitter that came with the T720 .
A) Flight was much smoother
B) Tx is still rubbish with this model
C) S720 is way too sporty for this Tx to handle

OMP S720 with T720 Tx (7 min 48 sec)

The Dinky Toy transmitter is just not good enough for the S720 . All that dead zone at the centre of the gimbals is just too much . The Tx from the T720 was better than the one bundled with the S720 , but the flight was still complete rubbish . The S720 is just too high performance for such a Trashmitter . I am really hanging out for a 3rd party Rx so I can bind the S720 to the Taranis .

From my personal experience with the S720 , there is no way I would recommend it a a first model or a model for anyone but the experienced . The S720 demands to be BNF or PNP so that a proper hobby grade tx can be used . The garbage tx that the S720 comes with , simply will not give you the flight experience a proper tx will . I am also left wondering about the CG ?

I used a zippy 350 and , is it still a little tail heavy ? or is it just the trashmitter that is so ???? The S720 did hunt up and down and for some reason rolled right all the time . ( Same as the first flight , just not so bad on the 2nd Tx ) The trashmitter simply did not fill me with enough confidence to try out the stunt mode . ( The flight performance in the fully stabilised mode was so terrible ) . The response to gimbals input was so lacking as to be almost laughable .

The first flight , did I give a score of 5 out of 10 , well this 2nd flight simply backs up my first opinion . 5 out of 10 .
Next time I fly the S720 will be on the Taranis ..

Review Part 3 - Yak54 Aerobat EPP 800mm Wingspan 3D Plane - Maiden Flight + 1

Yak54 Aerobat 800mm Wingspan Kit

Banggood GCRC

Here is a link to the Video:

I have been wanting to Review a 3D Plane for quite some time.
In the right hands, they are very Aerobatic but also Graceful in the air.
I've never flown a 3D Plane before so they're won't be much in the way of Grace but definitely some Aerobatics ;-)
This Yak54 is an 800mm Wingspan Kit, no Electronics are included.
Mine had everything it should, except for the Motor Mount, which I suspect fell out of the Box.
Yep! This time UPS strikes again!
When I received the box the Carbon Spar and Control Rods were hanging out of a damaged corner of the box so I suspect that is how I'm missing the Motor Mount.
The Build was pretty straight forward.
I didn't like the stock assembly of the Landing Gear so I performed a MOD on that ;-)
I wanted my Aileron Servo and Control Assembly on the Bottom of the Wing instead of the Top so I perfomed a MOD for that.
I also performed a MOD on the Cutouts for the Motor Mount as I wanted more surface area for gluing the Motor Mount.
Everything else assembled as it should.
The Kit included the Carbon Wing Spar, Control Horns, Control Rods, Control Rod Linkage Stops, Control Rod Supports, Velcro, and the Control Surfaces are already Beveled...Continue Reading

The Sr-81 was a disaster......only because I'd neglected to do routine maintenance on my CNC machine....nothing,

Back to tried and true methods......I found a 2-off from the early 1970's......the Northrop YA-9, which lost the competition to the A-10.
First blush is a 48" span with twin 70's (y'all know how I like my twins).

Generating the parts, pieces, templates today..will cut it out this week

This Memorial Day, my tribute honoring those who served with valor and cherishing the memories of those who gave everything -- A performance flight of my Arrows RC P-47 Thunderbolt 980mm 4S High-Speed Custom Variant "Silver Lady" flown today.

Arrows RC P-47 Thunderbolt 980mm 4S High-Speed Custom Variant Memorial Day 2020 Flight (4 min 47 sec)

I actually wasn't planning on getting any flight video, but Robert surprised me when I spotted him halfway through with his iPhone out, recording my last flight of the day with the rest of the guys watching. I think he did very well capturing the Silver Lady in action! 😁

Just to recap this project, I customized the internals of this new Arrows RC P-47 Thunderbolt 980mm to have the exact (or better) schematics of the old FMS 980mm High Speed P-47 Thunderbolt (now discontinued). The stock Arrows RC 3S motor has been replaced with a new beefy FMS 4S 3648-770KV Brushless Outrunner (the motor mount has 2 different mounting points, one for the smaller stock 3S motor, and another set of deeper motor mounting points for the larger 4S 770KV motor.. which confirms that this current Arrows RC P-47 offering was once the FMS High Speed P-47 model), and the stock Arrows RC 40-Amp ESC has also been replaced with a ZTW 85-Amp Mantis with 5-Amp SBEC.

Measured 54.5 Max Static Amps, 855 Watts Power - using an Eflite Power Meter and fully charged Admiral Pro 4S 2200mAh 45C Lipo.

I also completed a lot of detailed setup...Continue Reading

The Zeez Racing Combo is a F7 flight control and 4x60A BLHeli_32 combo that includes 4 plug and play discrete, addressable LED strips. It is in the standard 30.5mm mount size meaning it will fit 5 to 8 inch quadcopters. It can be considered a premium set based on the retail price of just over $100 but the cleverness in design and execution in quality make this stand out for me.

Here is my overview so far:

I'll be working this into a powerful 6 or 7inch long range quad to take advantage of all this combo has to offer.

Just took care of an RC plane that Ive been working on for a few months. After yet more and more adjustments I got it to fly this morning. Not very well but it was controlled. This afternoon I was going to use a heat gun to smooth out some wrinkles in the covering. That worked but it caused the surfaces to warp. I should have realized that would happen but I didnt. So it a fit of perpetual annoyance with this belighted pile of crap I smashed it into its basic parts and threw out the useless bits. Cut my hand on a wire but it wasnt too bad. The older I get the more things like this piss me off. Im going to stop building airplanes, Im just crap at it. Seriously thinking of trashing everything and just giving up. Its not fun any more, its just one failure after another, bad memories and memories of people associated with aviation that just make me more aware of my failings in everything.
