So for some reason I’ve started having major signal issues. I can’t get out more than about 60-70 ft, sometimes 100, but in certain orientations (left side facing me), it sometimes fail-safes at like 30ft out. I’m thinking maybe the antenna shifted in the body? Or something else? Any tips would be great. Before I tear it open, isn’t there a photo teardown of the Skyviper somewhere? I cannot find it.
Thanks
Antenna are inside the left side legs. FC’s is in the front, Cam board’s is in the rear. I was curious as to why the magnetic field of the motors when running didn’t interfere with their operation.
Does the motor calibration help with radio signal or just prevent compass
issues?
Good question.
Here is something you might consider. Remove the FC antenna from the leg so it exits and zip tie to the bottom of the battery holder. Experiment with orienting front to rear or side to side and measure the drop out rate.
One cool feature of this drone is all the antenna, drone and transmitter, are removable using industry standard wireless connectors if you need to.
So I did a teardown and reassembly. nothing looked wrong inside. except that the antenna wire was a tiny bit out of place in the leg…but overall it looked fine. I’ve attached the log…maybe someone can help. My transmitter has brand new batteries…so i don’t get it. I even walked around my living room after my teardown and in the logs i just see random drops in RSSI for no apparent reason. I was walking around my living room…around the drone. clearly something is causing interference all of a sudden…and i wasn’t running motors.
Log pre-teardown, flying in huge open field, no obstacles:

after teardown and slight re-positioning antenna. no motors running:

any ideas would be great :\
yeah i could do that…but i’d rather figure out what the issue is first. i did have a bit of a crash the other day…but i’m not sure how that could have impacted (no pun intended). That is why i decided to tear it down though…to see if anything was loose. but everything seems to be snug and in the right places
so what are those connectors called and what are the specs of the antenna. I may look into buying a new antenna for internal.
I really have no idea why i’m having such signal issues.
Going to try the pull the antenna off an old router mod, eh? I have no idea of what the connector is called but here is the one in the xmitter.
It’s strange they didn’t route the antenna up there stantion. It’s a fake.
When I get a chance, I have a theory that my reception is better when I’m
not using my phone attached to the controller. With the positioning of that
short antenna, it is right behind the phone, so it is probably blocking the
signal.
I just don’t get why they made it that way.
I moved my arial to this position. An found it to be a lot more responsive and distance was greatly increased once i disabled the fence.

Do you notice a signal delay from the transmitter at all. I tested and see a full 3 sec delay from the time I drop the throttle or hit the stop button till the time the copter actually executes the action. This caused me to fry a brand new motor when it got tangled in a small branch. I was quick enough to react but it didn’t stop the motor.
Lee, we can’t see the pic. It’s saying we have to have an account.
I see no at all delay when i have a connection. But it drops connection a
lot now. And sometimes, I don’t get a connection back until it is right
over me.
I really want someone with experience to answer this, could my motors (they
have many hours on them now) be generating the interference? I don’t want a
maybe, looking for a “yes, motors that are wearing out will start to emit
more EMI” 
Have you tested the area with a wifi analyzer? I see about 8 different signals if flying in my yard. Possible that’s where my delay problem exist.
I tried playing with that Mi Wifi USB repeater/amplifier stick but could never get the app to work right.
I was out in an area with no other signals earlier today with no improvement. I really think something has happened. I had a crash the other day, but everything was still flying fine. I really want to get info on motors potentially causing EMI issues. I know they are starting to fly different, but I don’t want to start ripping it a part and put these 3rd party motors into in unless i have to. plus the connectors are diff so i’ll have to solder and it’s just a lot to do if it isn’t the right path.
If I don’t get any good answers…it might be time to get adventurous.
Nice frame for the price. I’ve had the same thought as I hated having to disassemble the quad to get the motor out.
And solder only once! I made these SV motor to 1.2mm adapters. Just a couple bucks for 20 M/F pigtails off EBay. Next time just plug and play.
Lee, Your pic is still not showing up. There is no reason to host it on another site. When you post or reply just drag the file to the post and it will upload and display it. This is all we see.
For some reason when I try direct from my phone says file is to large which is why I use photobucket. Tho I think I got it now lol.
Cool, yep I use a photo resize app for forwarding pics in messages.
Neat mods with the 5.8ghz cam and external FC ant. Did you get a stash of Syma batteries?
No didn’t want to carry to much weight so added a micro capacitor to maintain power to the sv which fitted neatly inside the shell (just) and made a split adaptor to run the cam.
