Quadcopter Range Hack
done the range test... i went over two football fields... awsome
what is the right length to expose.
i just did that. It seems to work. but not done any range test yet
salvaged from an old modem. odd white color. but works fine. there was no ground pad so i groundes the shield on the negative battery terminal. not done any range tests yet but it seems to work
the cable length does not matter. just make sure you expose the inner wire, from the shield, the right length at the end. dont cut off the inner wire cover.
oh edit... i mean... if its a connector then forget obout exposing i said earlier. its just that the length does not matter

hi there,how long the coax cable do i need to replace the stock one ?do i have to cut the same length as the stock one then screw on the antenna or it measure with the length of the antenna ? coz i got this pigtail to male SMA cable about 20cm long.. and 5db antenna from unused routerthanks
HelloLights quad copters (x5sw) After clarification (Turn it on), the remains blink and as a result, is not connected with the radio control. In your opinion, what is the problem??? It is unpleasant for me and I have decided not to buy Syma Products the company.
Hey guys not to be rude please dont take it this way because i see a lot of real nice hack's/jobs but the reason recwap said to use a 2.4 ghz antenna is they work but usinging a specific length and if you just use coax cabel you can pick up undesirable frequencies and your quad could end up following someone else , my father is a professional radio operator and makes his own antenna's and has been teaching me for years so please becareful doing these mods , you cal buy these Antenna's at goodwill real cheap. Be safe and have fun.
hecmeans the wires from the board to the battery compartment. Then solder them back when completed this hack
did this work?
ya you need to solder the outside layer to any grounded spot. see if that helps
its the gold pad above the 2.4ghz
APCC DSLR Controller
the pad is under the white goop. carefully cut it away and pry the cylindrical component up a little bit to expose the pad and give yourself enough room to tin/solder without a short.
Hi friend please help me my quadcopter one wings is not working when the wing work then another side wing is not working when all 4 wings will working 2 side wing are very powerful please tell me the solution?
i dont currently have the ability to take a picture, though i will make sure to later. Yes, i did strip the end of the antenna , i have it working now, but for some reason whenever i turn it on i have to push the antenna one way or the other allowing for the connection, im not sure why this is but once i get a 2.4ghz wifi antenna im sure it will be fine, but im still confused on why i have to push the antenna.btw, sorry it took so long to reply i didnt have time - libstergames
I did this mod to my controller and then put the old antenna off of my controller onto the drone and extended the drones antenna with another bit of wire. I then put the extended wire inside the antenna and did a range test. I got 250 metres! - isaacmcn127
Can you show a picture? And did you strip the stock antenna?
Be sure to post your results, I'd love to see how it worked out. Also for those interested, there are several instructables on building your own yagi antenna.
Hi, i was doing this hack, (kind of). What i did was i just stripped the plastic around the wire to try and give it a little bit more range, but now the controller does not beep when i try to turn it on and the lcd does not turn on either pls help
Great!! although the other day i bought a fake syma X5C off ebay for only $50 and it had much more range than my friends original one that he paid $150 for!!!!!!!
I did the controller mod with a 2.4ghz antenna i ordered on banggood, didnt ground the tx as i have the new board but couldnt see a nearby ground point and was getting a range of 175 feet. i ordered 2 antennas so i soldered the 2nd one to the quad board and grounded it. Just did a range test and now i get 565 feet. Huge difference adding the antenna to the quad.
These wifi 2.4 Ghz antennas needs to be pointed perpendicular to the copter. Pointed them towards the copter is the worst direction. The signal is sent out in a circle around the antenna. These means in flat houses with wireless routers, you point them up on the router and on the computer.For more than 100 meters, maybe use a 2.4 ghz yagi antenna pointed towards the quadcopter. You could spend $30 on the good one on amazon with good reviews. Do not get the cheap ones on ebay and amazon...they do not work as well as this instrucable's type of antenna. You can make your own if you can find a reliable source for the specs. Also, you probably want a half wave dipole (1/4 wavelength on each side, 3.125 cm for 2.4 GHz) as the yagi "driven" element (the dipole) instead of the type that is folded into a loop as the dipole ("folded dipole") because the half wave dipole is only 75 Ohm and the folded is 300 ohms and the transmitter is probably sending out constant voltage so lower ohms means more power transmitted, Watts=V^2/ohms. A 5 element yagi about 6" long might get you beyond your ability to see where it is flying. I am going to try this, along with making the quadcopter's internal antenna an external vertical dipole. The yagi should be oriented in the same direction.
Just did this myself, I had the new controller type that did not have the ground pad on the transmitter chip. I just located a common ground on the board and grounded the new antenna there. I pulled my antenna off of an old 802.11b access point that was destined for the trash, after testing I went from about 80 feet to over 450 feet. I still have a second antenna from the access point in case I ever need to do it again too!
This antenna is great http://www.banggood.com/Wholesale-FrSky-2_4G-V8-Series-5dB-Module-Antenna-p-68703.html?p=KX28152008068201507H
"Walk" range tests, described at http://ClearStarryNights.com/Syma gave me 120-170 m for the Syma X5C with a stock transmitter.
I have a V2 main board and the same 2.4 wifi board as you. I just completed the upgrade. I used the single hole in the 2.4 board for the transmit wire. then I found a ground on the main board that went to nothing and soldered a pigtail from the main board to the antennas ground wire. The transmitter seems to work fine.
Quadcopter repair - motor replace
Do you know how to hack this transmitter so that it would work on a different quad-copter with a different brand?
It will work, but the range will not be as good without ground. I got approx. 100 m with and 40 m without.
Couldn't I just run a wire from the ground on the pigtail to the negative power input, instead of the tiny ground pad? Would that break the controller? - P07a70
What will happen if i conect the antena without ground? - BoštjanČ
Quick question, is that ground just the negative power input? I'm thinking on the remote I could just run a wire to the negative power but I'm not entirely convinced it wouldn't brick it. - P07a70
Can I use an old tv antenna for this? - Aruffing
hi. Can i see the picture where the ground could be. I have the same board as you. - BoštjanČ
im have the same board with no ground did you ever figure this one out? would love to hear what you did! - TylerA26
The 2.4 ghz pigtail I got was super small, I wasn't sure it was coaxial at all (it probably is) but like a caveman, I just soldered it to the tiny antenna and figured it couldn't hurt while I waited on my EE friend and more research. I ordered the X11c or whatever remote (orange one) because it controls a x5c and has better range. Too impatient to wait on that, I ran across an insane deal on a pre-modded Devo7e on ebay that can fly the X5c and I should have it this week. If I ever open up the stock TX again, I'm going to probe around for neg ground (I didn't before). I did uncover a possible contact pad diagonal towards the center of the mini-board by the antenna under some white stuff that could be ground. - andyc73
Hey guys, any idea where the second connection is for this newer board? I want to go with my 2.4g coaxial antenna, but I don't know where the other place to put the ground(?). Usually it's right below (towards the other board) from the first lead. Mine doesn't have a connection there, but something like it diagonally towards the big silver thing. Help!Where do I solder the other side?
I had a dual antenna 2.4ghz router so I also changed out the antenna on the quad-copter. I removed the old "antenna" and used that wire as a jumper for the shield to ground.
