Hubsan H501s Long Range Mod Easy way

Do you like it ?+5

Long range mod for hubsan H501S can easily increase FPV distance to 2000 meters. This mod can do every beginner, cause it’s really a small chance that something can go wrong. I will try in this article show you step by step how to do it.

What do we need :
hubsan h501s long range mod 11

2 x screw driver ( slotted and phillips )

2 x RP-SMA Female To U.FL IPX 1.13

1 x FPV 5.8ghz antenna RP-SMA male

1 x Signal 2.4ghz antenna RP-SMA male

Good quality set ready to install

At first use phillips screw driver and open a remote control

Now we see two black cables connected to antennas.

And this is a tricky part to disconnect them. Be very gentle and don’t use to much power cause it’s easy to damage the socket ( Do NOT pull the cable cause this is the easiest way to damage a socket or even break an electronic plate , a socket is quite tight so be patient ). To do disconnect cable I am using a slotted screw driver .

Now we can remove old antennas and start drilling holes for new ones. At first try mark a point on the middle, then drill a hole. At the beginning I am using a drill to make a small hole, later I am using a small kitchen knife to enlarge the hole ( just put blade inside the hole and rotate it , for me it’s best way cause I can easy manage how big hole I need.)

When we are done just screw on RP-SMA cable to housing

Now connect cables to mainboard

Close housing , screw on 4 screws and it’s done.

This mod is really easy to mange and it’s worth to try, cause hubsan can easily rich huge- distance 2000meters ( quite impressive for drone at this price )

If you know some other mods or even same as I did please submit it on FPVtv it will help this community growing – Submit Post on FPVtv

Cheers

    It really is amazing that you have increased the range. I really am impressed. However I have another question Sir. I have Hubsan H502E X4 (do not mix it with H502S). How can I increase its flying time and range? It uses a 7.4V 15C 4.5Wh 610mah battery. This battery now works only for 3 mins, after that drone can not even lift off from ground and keeps circling 2cm above ground and breaks propellers. I am searching for another battery from long which is more than 610mah; but I am not able to find the same size of battery with same configuration. Can you help me in this matter Sir? Is there anything that can be done to do something more than the stock in Hubsan H502E (Its not H502S)? Kindly suggest me if possible.

    What antenna combo do you recomend to get the max distance out of it. Is there a spec that it needs to meet? and do you have a link to the ones that have been the best for you?

    thank you! I have a few more questions if that’s ok

    1 . Is the white antenna in the picture and the smaller black one just extras? Or do they go on the actual quadcopter? I understand one is for fpv and the other is for the signal but there is 4 antennas in the picture so I’m a little confused sorry I’m a newbie :/

    2. This is the battery I plan on using and obviously some kind of voltage regulator for it as well. Would this suffice?

    Hi I am very interested in this mod as well. Two questions here:

    1. Why in the picture does it have laid out what looks to be two sets of each antenna?

    2. If I were to also mod this controllers battery to a rechargeable lipo would everything still function ok? As I’m sure your aware this controller EATS batteries and probably even more so with the mod.

      Hi Trystan
      1) One antenna is for 2.4ghz and second for 5.8ghz ( FPV )
      2) Ofcourse you can use lipo 2s or 3s and everything should works just fine, but I think 3s battery could be too much for long use ( higher voltage can heat electronic parts inside transmitter) . I will stay with my AAA batteries cause they can be fully charged without worries that they been damaged ( fully charged lipo batteries should be discharged in max 48h otherwise cells will be damaged ). Sometimes I forget to charge batteries for a drone xD and if I will have extra lipo in TX …. 😉
      Cheers

      Hi there, so at first you have to find good frequency ( in my case best one is 5840mhz , but mostly I have to find new one at some new places ). This should help cause now your FPV receiver is much more sensitives.

      I am using fatshark RHCP antenna and works just great. Don’t use LHCP antenna cause this could be incompatible, most antennas that we can buy on the market are RHCP. I also checked other cheap RHCP FPV antennas and works good enought so no worries, just find best frequency without any distortion / noise.
      Let me know if this help.

      Cheers
