Does it WORK!...
12€ on Amazon!...

works for me but you have to point at ac all the time and keep adjusting

Thanks TMUSVI!...
For the price i think i'm going to buy...
At least the video signal will be better, and i'll have more control in the 500m range.

look on ebay think there cheaper mabey not price seemed to double

Let us know how it works!
Like same day, same location, with and without the range extender test flight

A even cheaper copy of the cheap "originals" direct posted from china?
Well done!
Is it working?

Nice work!...

my personal experience with range extenders of this type is they are super hit/miss. i cannot figure out a pattern.   sometimes clear advantage to them working other times its fairly equal with or without them.   i have 2 sets.. cheapy one and a slightly more premium one.. both from amazon both perform identically.  i have tried it on my spark i used to own, i have to say not worth it, at least in FCC areas where have higher output.  only run where was clear advantage to them was one  run i did from friends hour to a gas station 1.5 miles away, the spark without them barely got 2,200 feet because so much in the way, so many trees and hills and homes and blah.  but with the extender cups the little spark made it all the way there and all the way back... it was the only time when it made a clear difference.  i could not repeat it again however, so i dont know if that very moment of the test conditions favored that signal or if they really did their magic..

with the mavic pro however it seems it actually is not as ideal, i think because mavic pro is outputting a lot more power and senses reflection coming back into the antennas it cuts power slightly to prevent damage to the circuits..  that's a theory but with my mavic pro it has been less then ideal at all tests, not one time it thus far extended my range at all..

ok here is your test 2419 ft no boosters return to home lost signal  

put on boosters sent out agian 3568 feet rth because low battery could went farther DID NOT lose signal

all this with otg cable on 5.8 and sitting on the roof of my house YOU MUST HAVE LOS to ac to fly far will post log  so COOL luv my spark ye haaaaaa

so many trees and hills and homes and blah

thats why dude los you must have line of sight  if you want better buy a mavric pro i am going to opps see ya got 1 whole diffrent drone flew my friends cool have fun

already a step ahead.. got my mavic pro.  however dont expect the mavic pro to work better on these signal booster cups either.  without any mods or anything i'm extremely happy with the range and battery run time, the mavic range and battery life is perfect.    my longest run thus far is 4.46 miles out before signal was worrying me, it wasn't fully recovering from its blockiness and graininess and warnings all over about signal.. but there i was running these test less than ideal.. also tested it in my car see how far it goes and very impressive..   manages around 1/4 mile before i get warnings.. thats a big zone to play around with if your trying to follow your own car around from the air..

yes i agree 100% mavic  pro does not need them o and tks for all your posts you taught me alot

TMUSVI Posted at 2017-8-27 15:30

not a problem.  we're both learning as we go!  i two wish the spark was better though.  spark is the perfect size for a lot of things.  but the mavic pro isn't that much more of a burden to carry! and its worth it for over 20 minutes of run time, about 25 avg if you're gentle and smooth and in normal mode.. or depending how aggressive you are, 15-18 minutes in sport mode racing around..  wireless range is said to be 7KM which is about 5 miles.. 4.5 miles i dont know exactly but i managed to get extremely close to that range and not only that i'm sure if i had a more wide open area i could beat that.

Thanks for testing.
Now just see if somebody in EU (CE area) will try these!
I don't know how it will improve 'here'.

Just bought... Estimated delivery: 6 Sep 2017 - 23 Sep 2017
There will be a CE teste soon!...

Looking forward to that.
Also how it behaves in general (like do you need to point your RC more exact to the AC etc.)

yes you do

For sure.
I can't sleep already ;)

Yes it works!.... I did get more 110m!!!! Not bad...

Return to home _TIMEOUT OPERATION??????

only 110 meters?

i thought the spark can go as far as 2klm with a signal no?

i have not got mine yet but flew about 450m with out them fine already

CE land - An easy test that I did that seemed to confirmed to me that do work, was to fly the spark out over 200m - I would then add and then remove the reflectors several time while watching the signal strength.  In every case, when I removed the reflectors the signal strength dropped. I now always carry it with me and quickly add it when needed.  Generally I do use it, because I am not always facing the drone and if your not with reflectors attached, they do more harm than good.

ooosh, i ordered two, one for the mavic and for the spark i got for my son but....i plan on getting a second spark for myself  now because of this, i love my mavic pro but its just easier to get into tight places with a spark and based ont he specs i cant see how a booster does anything for the mavic since the batteries drain out by the time you get out there and have to RTH, :/
