This sleek Composite EDF Jet is set to turn heads and get the adrenalin pumping! Constructed from Fiber Glass and built up balsa with a thin main wing airfoil, the Silvia 70mm will cut through the air like a razor. If your looking to step up from foamy EDF jets and break free of the speed limitations that are inherent with foam models then the Silvia 70mm Edf jet is the model you have been waiting for.
This kit will require some assembly time and knowledge of composite model construction. You will require a 70mm EDF unit, a Brushless EDF motor around 2800kv to 3200kv, a 2200mAh+ 4s 14.8v Lipoy battery, a 50Amp ESC, 3 x 9gram servos and your own transmitter and receiver (Tx/Rx) to complete this model.
I put a 80amp ice hv esc on 6s 65c pushin a 2200kv in the edf that came wit the silvia.
But there is no thrust . This power set up made my other jet. Wich is bigger have endless vert and
Flat runs of 140. What the issue here? That thing cavitating or what
This set up should be sick as Hell in this. Little jet what's wrong
Check your ESC wires if they are connected to your motor properly. You might have reverse thrust. To correct this problem you can swap the red and black wires. Hope this helps . ~harry
bon ma question est la suivante. Cette Silvia jet peut installer un aterrisaje en train ré*tractable é*lectrique. si elle est positive pourrait m'informer que mè*nerait le train modè*le ré*tractable.
has anyone noticed the original HET super sniper the wooden spar is designed so the wings are angled up and the hobby king silvia the wings are flat and the wood spar is also flat?
I bought this model and the problem you're going to be happening with it is not only the wings don't have a very good airfoil on which I had to make my own airfoil on top of the Wings. The fan and motor system sit right underneath the main wing so you won't be able to put any type of battery pack in the front nose section to get the plane Within CG.
hey grego i placed weights in mine the furthest i could move the weights back under the canopy and the max battery weight i could get was around 220grams give or take a little so u could run a 4S 2200mah but im only at the beginning of testing i havent tried to move more weight forward yet
hey grego im running the high torque 70mm EDF 4 blade with a turnigy 2836 3200kv the battery is a zippy compact 1500mah 4S remember to loctite the motor screws and the impeller adaptor to the motor shaft ive had the stock 3 blade fan that comes with this silvia and a freewing EDF impeller both come loose i think it has something to do with the small exhaust ducting and the back pressure
sorry grego this is the EDF im using "High-Performance EDF Ducted Fan Unit 4 Blade, 2.75inch, 70mm (AUS Warehouse)" its available in the international warehouse as well
HI please use the Lipo Finder on the front page and filter to 4S 14,8Volt Lipos with a range from 2200 mah to 2600mah and an minimum C rate of 20
all of these fit perfectly in this baby
I'm sorry to say it man... This god da** plane can't fly :-D
I've tried 6 times, also with boungy, it have not been in the air yet..
Beautiful plane by the way.. :-)
i found 80-90mm back from the flat front part of the wing where the pins are is the correct CofG start off in between those two numbers and adjust to your flying skills
I finally got to fly the plane today. First flight I did with a 4s 2200 lipo and a 3600 kv motor and the three blade 70mm fan. hand launch got it in the air with no problem to my surprise However i was disappointed with the speed It is fast but not ballistic like i hoped. So i tried my next flight with a 5s 2500 lipo and have to ad a lot of tail weight to get it balanced Next launch id tipped over and destroyed Mostly due to the extra weight added to balance It fkys good when kept light but im not going to bother trying again with a new one cuz its to slow for my liking and not enough room in it to put a descent power train in it WAY to much monkey &^$%ing around with no room to achieve the desired goal But if your content with just a bit fast then this might be your plane
the plane isnt designed for a beginner there for a beginner wouldnt know how to assemble the jet no instructions are included although u can look up "het super sniper manual"
On forums I find that Eflites fan blades are brittle and when you have to do maintenance they tend to crack. Better choice for that type of money is a Wemo or HET.
This plane seems to be a cheeper version of Het SuperSniper 70.
I have one, it's very fast flying model (over 200 km\h).
Do not by cheep edf and motor - do not waste money!
Het 70 mm or Wemo - Give 30% more power
with the het fan unit you can really pump out the watts of the motor... all they did is change the colors of the supersiper and called it a diffrent name www.link
Anthony you are killing me!!! I have had to write my wife out of my will due to OCHKD (obsessive, compulsive Hobbky King disorder). If I pull the trigger one more time, SHE WILL TOO!http://www.hobbyking.com/hobbyking/store/images/ em_cry.gif
principone I cant seem to find anyone who bothered to answer your q about CG Seems kinda rude seeing as there are many who would know because they are already flying the plane. Did you by chance ever find out? Id like to do my maiden without a disaster if possible
Ken, maybe Principone and you should read the top of this tab, and realise you can ask questions independently rather than irrelevantly tacking onto someone else's unrelated thread? Seems kinda rude that you'd try to muscle-in on someone else's discussion and then expect center stage. Click "Ask a Question" at the top right of this TAB and your query will be put at the top of the list for all to see, and also featured in the daily questions list, rather than lost here.
I gots to have one just what the doc ordered ,,,,,,,,,must Fly,,,,,must Fly.No must resist, to many good toys must resit. Aaaaaaag, I will order one!!!!!!!!!
You're probably right pavcon, I was thinking about space to fit battteries etc and trying to keep it as light as possible too after I wrote that. I'll wait till I've got the model here and can get a better idea what would fit where then probably change my plans to what you suggested or maybe something even lighter.
With the sniper it was easier to use 2 packs of 2cells rather than crack the canopy hatch opening fitting one 4 cell. Just add velcro to the inside of the sides. My 2 cents worth, other 2 cents worth has been the nano-tech batteries, but you already knew that. *) -hey, have fun with that ship k!
It looks a lot like a ProEDF model... like the ProEDF Silvia. Even down to the colors.
Same manufacturer as the composite L-39, F-18 and F-22 previously released.
Its a fraction smaller than the HET Super Sniper but looks identical in form and function. The EJF in the US sell the sniper for $129 so I'm not sure how this is such a great deal w/ the expense of shipping. I personally think the snipers are hard to balance w/ the fan/motor placed mid section. I had to use saddle packs over the wings to make it work. Plus, the have super high wing loading so becareful making hard turns
Hey heychas, incredible as it sounds, not everyone lives in the US. Given the EJF option of paying $129 shipping from the US, or paying $87 shipping from HongKong, I don't see how the EJF option is such a great deal. For someone living in the US I agree with your stance.
Straight up - thanks for pointing out my ego-centric world view. You are correct. If you get one, let us know how it goes. I had to use 2 x 2s 1800 mah under the wings (in parrallel) and 2 x 2s 1800 mah under the canopy against the ducts (in parrallel) and then in series w/ the others... and I was still slightly nose heavy. For catupult launching I found the best spot was 70% of the distance measured from the nose to the cog.
Yes, looks like the habu but smaller. This seems like the announced 70mm version of the stinger.. Those wings look pretty slim. It would be difficult but not impossible to fit retracts. Fixed gear though should not be a problem.
Forget retracts. The wings are to thin to put retracts in. Even a normal servo (11mm thick) will stick out of the wing. Also keep this model light, because of small wing surface
Its impossible to set rationally CG if to put the one battery to the nose(the pilot place). You have to use 2*2S batteries connected in series- one to the pilot and one under the wing (fuselage), the ESC has to be than at the same place (fuselage).
It's a pity the EDF housing isn't set a bit further back. That way you can much more easily achieve CoG without having to use 2x 2S batteries in serial.
How about a verion 2.0, HobbyKing? One with the EDF mounted another 6 inches or so back? The average modeller could already do this but seeing this model is supposed to be ARF, would be nice if it was already like this.

Finally got this plane in the air. Setup is HET 3904 fan ARC 28-48-1
4s 3000 Turnigy 40C. Hitec HS 125 mg servos. I epoxied the elevator servo in the tail just in front of the block for attaching the horizontal stab screws. Had to add one ounce of lead to the tail to balance at 70mm from the leading edge of the wing at the fuse. Also cut the exhaust opening just aft of the stab to get it to 50mm.
All up weight is right at 3 Lbs.
This thing is FAST!! We clocked it with a radar gun at 162mph. I would guess the landing was about 65mph. Probably could have landed slower,but i didn't want to tip stall it on the first flight! Even at that speed a belly landing in the grass is no issue.
This is defiantly not a plane for beginners.But if you have a need for speed this will do!
Nice job HK !!

arrived well packaged went together ok there are pre drilled holes for the elevator and wing just covered so dont make new holes the tail cone is very tiny but still manages to work the elevator servo mount fell to bits i just glued the servo to the inside the control horns are weak so buy some when u buy the jet everything else is great flies beautiful i used a hobby king / change sun 70mm 4 blade EDF hobby king turnigy 2836 3200kv motor zippy compact 1500mah 4S u can run a max battery of around 220grams without CofG problems CofG is 80-90mm back u will need to make your own exhaust ducting and EDF mounts i just used balsa u will also need to cut the inlet ducting to squeeze in the EDF as there is just no room and u will need a bungee cord to launch this model also there is no bungee hook included i used a small 3mm bolt and bent it to the shape of a hook overall great model flies beautiful check my video in the video section

Model comes with no instructions so I had to use the instructions from HET sniper Jet to just build it. Using foam I had to make a new airfoil shape on top of the main wing because the main wing doesn't have any type of airfoil shape to get this plane off the ground. The motor and fan assembly mount right underneath the main wing by doing this you will not be able to get the model within CG or carry any type of battery power.
This model is only for advanced builders. I would not recommend this for any beginner flyer intermediate flyer.

Hi, i recived my Silvia kit today. Looks nice, here are the component weights
Fuselage 344g
Left wing 64g
Right wing 62g
Elevator 22g
Canopy frame 6g
Canopy 8g
Hardware 40g
There was a EDF unit with my kit, PRODUCT ID: 701F, i also bought on. Now i got 2 EDF units. One for testing and one for blowing up ;)
It's going to be a challenge to accommodate batteries, 2X3cell might be ok. A 5cell pack is not going to be easy... there is room i the fuselage, but getting it in and out is a challenge! The canopy opening is narrow.
I am going with this motor PRODUCT ID: XK2858-3600KV and 5 or 6cell lipo on the 3 blade EDF.
Now on to the build....
Best regards

My kit just arrived and I have to say the quality is excellent. The fuselage moulding is nice and smooth, paint is pretty well applied (not perfect, but fantastic at this price). The wings are balsa sheeted foam, and nicely covered. There are two very shallow servo bays in the wings for the aileron servos, and a ply frame for mounting in the fuselage to take the elevator servo.
The battery bay will take pretty big batteries, but the cockpit opening is narrow - only 32mm at the widest point. I'll be using Turnigy Nanotech 6S 2650 batteries which don't quite fit through the hole, so I'll be taking a dremel to the lip to get them in.
There is not much room for getting a fan unit in. I'm going to be using a Wemotec Minifan and will have to cut away some of the intake ducting to get it in. There's also no thrust tube or even mountings for the fan, so I'll have to epoxy in rails.
There is no manual with the kit, nothing at all, so I'm going to have to calculate the expected CG position and see what happens. I'll also be fitting a bungee hook as there is no where to hold it for a hand launch (plus mine will be on the heavy side and the wing isn't huge). I'll post another message when I get a decent CG sorted (may take some time though, lots on the bench!).
In summary: great kit for the price, needs a manual or at least some indication of CG on the plane, and this is NOT a beginner
