S800 Sky Shadow FPV wing from Banggood (flight test and summary)
Vložit

- This S800 Sky Shadow wing from Banggood flies very nicely indeed and the stabilization system really does make a difference. Here's a summary of the pros and cons:
Pros:
- excellent flight characteristics
- tough EPP foam
- a good price (aka: cheap)
- PNF kit contains most stuff you'll need
Cons:
- ESC appears to be junk (I'm not the only one grizzling)
- servos are perhaps a little light for the job (gears)
- FPV transmitter was faulty out of the box
- the el-cheapo camera supplied is not worth using (I used the Runcam Eagle instead)
- the fit of the molded foam parts could be better
- the build does require quite a bit of soldering and extra wire and you'll need tools like a drill (2mm), sandpaper, glue and more tools than normally required for a PNF.
- instructions could be a lot better.
Bottom line:
This little wing really honks on 4S and I'm sure that once I put a decent ESC in it that I'll be flying it a lot. Would I buy the PNF version?
Maybe.
You do get a hell of a lot of stuff for the $30 more than you pay for the basic airframe -- although the quality of these parts is questionable.
Go check out the PNF version then look at the ARF version and decide for yourself which would represent better value to you.
Setup of the model flown in this video:
- FrSky D4RII receiver
- Multistar 4S/1400 mAH battery
- Runcam Eagle FPV camera
- ESC, servos, motor and stabilizer as supplied

Your video has convinced me to buy something yet again Bruce 😄
I've ordered one and just had confirmation that it's in the mail towards the Netherlands. Can't wait to build it. I'm a big fan of Teksumos because of the EPP so I had to get my hands on one of these too. These seem to be a great step ahead of the Teksumo and Bonsai
Hey, thanks for showing the maiden, i was curious. Kinda relieved now that I'm not the only slow builder. Will see if my esc is crap as well, at least my motor sounds good. Greets, Mario
Good luck on your maiden mate. I look forward to the video
Looks like a nice wing for the most part!
Great video and flying. Cheers :)
they always send you the "good" stuff Bruce!
Great videos as usual...very informative ! Can you recommend a first flying wing for me ? Looking for something which will be nice and stable and happy for nice slow floaty flying. And interested for upgradability for FPV and runcam etc... thanks !
Yep issues with mine were the VTX blew within minutes, and FC felt like it hindered the plane, launching felt it didnt have enough movement for the first 1-2 seconds, then was fine.
Flew without the stability and it felt solid anyway, so might just get rid, definitely better getting the kit!
I went for the KIT. I nearly ALWAYS do. That way you can put decent electrics that you KNOW will work because you have used them in other crafts. Mine is all glued together & is awaiting the electrics & FPV gear. I should get those fitted this weekend as it's not flying weather here in the UK. Although today isn't bad, but I've got other stuff to do today!
Thanks Bruce. Can you recommend a way to secure wings in a backpack foldable wing? I've used carbon spars and tubes, but that requires a lot of foam cutting and gluing.
Stick with it Bruce, I left my wings removable for the same reason, stick it in the Bonneville's panniers and fly a little UrbexFPV. damn thing can take a real hit too. PS my wife was watching this with me and said to tell you you have the neatest, best groomed beard. (mine is more Gandalf!).
Hi Bruce - Thank for sharing the maiden and the issues with this plane. I just ordered one of these from HobbyKing - not sure if it comes with the stabilisation system, but why do we need it? I watched your vids about wing design, and a good wing would be inherently stable right? Is this S800 not?
My PnP just arrived and the ESC is marked 30A. Fingers crossed it and the motor are OK. With hindsight I should have gone with the kit. I won't be using the supplied stabiliser with iNAV available.
Thanks for the honest review. I bought the airframe only kit when Banggood had a $30 sale. Honest value IMHO. I'll build it during the winter months. My other wings are not stabilized. Do you think this one will fly OK without stabilization?
FliteGreg flies great as is!
Hi Bruce, i have built the S800, but I am wondering how to put in the VTX in: with controls facing down so buttons and switches are accessible via the carbon cover openings, or heatsink facing down for max cooling through the cover openings. What are your thoughts? I prefer the first for practicality, but does the VTX loose enough heat when the heatsink is wing-body facing? Thanks.
hey Bruce. . love to see you do a Crashtest Assassin review
Hi Bruce did you do a build video for this wing?
I was wondering how to set up the flight controller?
I used a bottom emax 2300kv 2205 motor with some metal gear emax 9g servos, a 2200 3s and a 5045 (nonbullnose) props and its good. Btw for some reason it has less power with a bull nose prop so just use a normal one, although the bullnose prop is quieter. Needs some fpv gear in the front to balance though. I'm using an opto esc so I used the included 5v bec wich works great to power the servos and receiver.
Had esc problem with my other wing earlier and when the motor cuts out it started to smoke. Noticed that when I was testing the setup on the bench. After playing around with the wsc long enough I went to the spare box and installed miniquad esc and separate bec
Sipila.fpv cut in a 2mm fibreglass rod in the leading edge and laminate the wing. Will be indestructible then.
fixed wing Fridays are awesome. even if it is Saturday.
Thankyou for the honest review. I seriously hate the reviews that cover up the faults. Banggood only puts positive reviews on their site,if people do complain,they always say to contact them to get it resolved but no one ever says wether or not it was. I can say I got a quad from them with a faulty transmitter and they sent me a replacement one,and it didnt take that long. They do ask for a video showing the issue and a copy of the shipping label. For me it was showing the batterys were new,installed correctly and nothing happening when it was switched on. You shouldnt have any problem getting them to send replacement ESC except thats probably not going to help,that and the crappy motor. I would just ask for a refund and destroy that one if thats what they wanted. I sure wouldnt invest in it then find out everything on it is crap.I could build a Flite Test model with my own parts better than that,and so can you. I have a limit on what I spend with places like Banggood. That thing would be over that limit.
Hi Bruce. some years ago you had this yellow jet that you where going to maiden tohether with other models. Do you still have these? And will you fly them?
Yes, I was looking through the pile of models yet to be completed and I have about half a dozen that will be maidened this summer.
Could a Turnigy Evolution be used to fly this (since it has a 3 axis flight controller)? Another way of asking this, do you need elavon mixing or does the flight controller take care of the throws on the servos? Can the Turnigy evolution be used to fly any race wing?
Hey Bruce, can the timing on the esc be changed? I wonder could it be a sync issue. Cheers
As you missed last Friday, are we getting Biplane Friday this week????
You mention a better pnp model at the beginning what was that model?
Hi, it is great fpv delta wing, but i got a question from you, it s my first time i m trying to buy one of that, i want to know if i can you FPV gauges on that, and how to install.
just let me know if you can. please.
Hey!!! How did you get the cg right with a 1400?? I had to use a 2250mah 4s to get it right then it’s too heavy.... please give me some advice here as I cannot get this thing to fly smooth.
maidened mine today used my own gear no stabilization its a lot of fun fly's great
Those servo horn linkages look dubious to me. Wouldn't it be more reliable to use clevises or ball links?
Rather than drilling servo arms I've used increasing sized torx bits as a hand reamer, should only need two sizes and the plastic seems to get out of the way pretty well. Can be done in the field easier than driling.
You said sometimes a fixed-wing ESC is better than a mini quad ESC on planes. Why is that? If you meant that this needs a 30A instead of a 20A then I get it, but otherwise I don't understand why it would matter. Could you please explain?
Daniel Knight yeah i agree with ya
i prefer mini quad esc as they so small and very light weight with same rate amps
easier to adjust and more importantly it wont freeze up the motor in middle of sky
i guess bruce using 25a esc is too small rate for those bullnose props
bullnose props are so inefficient so 25a is not enough and of course that 25a esc got power out because its too hot
that bullnose props can draw about 32amps with 2205 2400kv motors
huh? why you reccomend to not use mini quad esc?
because power got out sometimes?
that is because from demag
i never got power out in flight with mini quad esc with blheli fw
all my 3 planes using mini quad esc with bl heli fw (abit adjustment ofcourse) and also
it's so damn light with mini one
You should do a video with all the upgraded equipment you put on it.
I will.
What's the difference between a quadcopter ESC and a fixed wing ESC?
plane escs are designed to cope better with sustained high throttle (I think?). quad escs are designed for short bursts
hanelyp1 but not with sudden throttle up with std esc
if you use correct setting in mini quad escs, you wont get any power out inflight
just disable dshot or oneshot,
and use correct demag settings
mini quad esc with bl hel fw are easy to set up than std one
Bruce, what is the stabilizer board that comes with that kit? I use a Naze32 in a wing but it was a struggle to get it working right.
I haven't seen this stabiizer being sold separately so it's probably worth buying the PNF to get the one they provide because it also includes a BEC and PDB which makes for quite a tidy install inside the battery compartment.
Bruce. Where is the airfield you use?
product description also says 3s max! 20a is for sure not big enough for 4s and a 6" prop
Hi Bruce! Anyone able to suggest a overall best bang for the buck fpv wing (prefer arf/rtf)? Thanks!
Also would be interested.
Zeta wingwing Z-84. Can't go wrong with this lovely little machine. Or Teksumo - they have a sale on hobbyking right now, you can get them for like 17 bucks
Use a different prop. Those bull nose always heat up my motors when I push them. The fuselage is disturbing the air, making it turbulent, resulting in even more for the prop to cut through.
hey whats the neutral position on your skyshadow?
What tape did you use to hold the wings on?
i thought of a idea how to confirm that air is indeed going through the vtx vent and out the ant hole above. simply put some flour or other powder in the vtx area, and have a camera on the cg fuselage set sideways to see it come out the gap around said antenna.
I purchased a teksumo and I've found even a mildly hard landing causes it to snap into several pieces. What can I do to make it a little stronger?
You can use a few runs of fiberglass tape along the wing and then cover it in laminating film. This toughens them up immensely. Did this with my Bonsai and it's survived horrendous abuse.
What is the name on the stabilizer? Banggood has a couple of different ones and I wanted to try the one that was in this review.
I don't know if it's available separately.
I thought you guys were 12 hours ahead of me, maybe you are behind... Friday/Saturday still good fun.
so buy the kit version and have a decent plane?
range of flight? and time off flight battery>?
How does this compare to the Teksumo ??
Wheres the cg on this thing, 4.9 in from nose?
1st and I was building this , just got it
what happens if the propeller ends up vertical when landing? wouldn't it be damaged? or always stops stright?
wallaguest1 with the mottor off it will be alright even if pointing 90° from the fuselage. It can be snapped by catching a rock or something while touch-down but it's unlikely.
If the mottor is on it will be damaged but a pack of props is around $2 so...
if its not a cheap prop it will survive most landings, got some cheap props (0.10$ per pair) from HobbyKing. those broke every time i landed with my FT mini Arrow and FT mini Trainer.
I'm actually having problems with my stabilizer on the sky shadow. If I have set up the wing as a elevon model in my TX could this be why the stabilizer is not moving the surfaces properly? Whenever the stabilizer is on, and I tip the nose down only one elevon reacts the correct way and when I tip one of the wingtips down then the other elevon is the only one to react. Any tips or suggestions to get it sorted, will be greatly appreciated! As of now I'm only flying the wing with the stabilizer off.
Yes.. remove the mixing in your transmitter and make sure the board is set to "DELTA" with the little dipswitches. From memory it's just one switch ON and the others off. If you use mixing in your transmitter then only one elevon will actually move very much when it tries to stabilize itself.
RCModelReviews Awesome! I'm so glad you mentioned that in the video. I have been stumped for 2 weeks, wandering why the elevons wouldn't cooperate with me. lol Thanks Bruce! And yes it's just the top dip switch that needs to be on, for delta mixing.
RCModelReviews You're a legend! Just got home from work and did what you suggested with the model setup in the TX settings. The surfaces are reacting they way they should with the stabilizer on. Thank you for the info, enjoy the rest of your summer!
Glad to have been of help Jamie.
Can you share your rates and expo for this model?
I'm having trouble flying mine, it's so sensitive. My CG is at the recommended spot and my rates are 70 and expo 60.
I think (from memory) that I have 50% rates and expo is about 40 but I'll check.
Been looking at those. Like to give one a review .
What is the name of that tape?
What is the average flight time ?
that looks a lot like the FT Arrow [ from Flight Test obviously ]...... Can you buy that stabilizer separately?
Ghrey probably plagiarism
Always buy arf kit and put your own gear on. The wing itself matters which is fantastic 👍
Sold , I'm having one of these , Cheer's Bruce ..............
So why the $800 in the description for this video?
Bruce! i gotta tell ya im seriously depressed that i did not have this video as a review 2 weeks ago. im positive i would of saved my 93$
i am not gonna buy any flying wing anymore. just buy some foam, hotwire it or glue it together in flitetest/experimental airlines manners. works like a charm
Exactly my determination, too. Nothing more satisfying, more flexible, or less expensive than rolling your own.
new gray s800 on sale at banggood
Is the ESC overheating maybe? Doesn't look like alot of cooling there.
Yes, it probably was overheating towards the end of the flight but it cut out on the initial climb -- long before it had a chance to get hot.
is the ESC rated for 4S?
Aiyo People :) will it bind with my tanaris plus?
you have to put your own receiver. I put a frsky d4rII, which fit well in the wing
Anyone find out where the perfect cg point is
The manual and most people say 125mm. I am at 135mm back and it is still quite stable but still requires about 4mm of up trim. It also drops the nose a little too much in turns. I think 140mm is probably about it. I fly mainly wings both swept and plank.
Not available anymore. 🙁
for 100 bucks, thats pretty awesome
this wing is tough as old boots
So, what I got out of this was buy the airframe kit. The electronics are crap, but the airframe itself is quite good. Get your electronics seperately.
for me the stock electronics work very well (for the moment, about 15 flights). I only changed the antenna and horn linkages. The camera is bad but it's "flyable", however I'm going to change it.
Sarris John newbie here too plz help!!!! i have installed a DYS motor (CW) www.banggood.com/DYS-SE2205-2300KV-3-5S-Brushless-Motor-for-Multicopters-1-PC-p-1043254.html and i have a Gemfan CCW prop www.banggood.com/Gemfan-6X4-6040-High-Efficiency-Electric-Propeller-1-Pair-p-975184.html is there a way for those 2 to work for a pusher efficiently or i need to buy a CW prop thanks???
The ESC is C**P the CG is wrong needs up elevon , The FPV TX does not work .. Other than that its a great Kit .... It only takes 1 day to build, the motor sounds funny ... uhmm
Yeah, the airframe and the stabilization board are great -- but there are too man other "cheap bits" in the PNF version. On reflection, the PNF is probably worth it for the airframe and the stabilizer -- you can toss the rest of it and still have a great-value little wing.
I agree with this.. I had a look at it and per the price u pay it would be a nice catch . Replace the esc , and paint it some very bright colours . It has a great wind penetration.
Can't wait to crash mine!
The motor bearing sucks because it's not a real sunnysky motor. Its a chinese cheap counterfeit. After comparing it to the same size genuine sunnysky motor there are many small things that are visibly different
cheap chinese copy of a cheap chinese motor ??
