Use a old JR SX600 TX and R610UL RX for radio duties.
Am using a dual battery set up consisting of a 3S 2200 for the RX and a 3S 550 for the VTX.

All together my plane weight 32 ounces and will cruise at less than half throttle.

My ground station is a backpack style as I am using a Patch and also plan to hike to a few spots to fly.
I have a ReadyMadeRC 1.3 Receiver (2 channel) and a 8dbi Patch antenna.
Am using a Philips PD7012 7" LCD screen for display.


Want to thank Alex and Markus for putting up with us!
I have read every page of this thread and myself was getting miffed at all the same questions being asked but you both are some of the most cool headed smart people on here.

This is not my photo below but made a mount exactally like it.
I like your outrunner mount. I have to tell that the motor position and resulting short propeller, read bad efficiency of the power system used was the main reason to retier my own Easy Star. Maybe I will reactiveate and modify it too!

Thanks for the flowers btw.

I also know that another vendor is shortly before hitting the market with another FCC aproved tx but I can't tell you more about it.

Markus,
But it is a 2.4 VTx...as you noted earlier, unusable, with 2.4 RC Tx's...Hopefully the FCC approved tx will be in the 5.8 band...that would be perfect.
Thanks again for your response.

Not really sure why everyone goes through the effort of modifying the motor mount so extremely. In my experience, such a thrust angle negates much of the easystar's gentle flying characteristics...

Try using a http://www.dpcav.com/xcart/Adjustabl...EPIC-Type.html

Also buy the recommend filter.

... where is it ?!

Is there a head tracking system I could use w/ MyVu Crystal goggles? would that be controlled by my QuadRino FC or the Vtx/RX?
I'm coming from a Foxtech 5.8ghz 200mw vrx/TX & fixed Gopro.
Would also need a pan/tilt gimbal & dedicated FPV cam.
Thanks!

I am under the impression that this guy here is FCC aproved.

No?

Changing the antenna of an FCC part 15 transmitter from the one provided probably nullifies any intentional radiator approvals it might have had.

Nope. Only the Iftron unit has a part 15 license...

Wiring Harness 101


Hey Guys,

I'm trying to make a wiring harness for my fpv unit but wanted to get some clarification before I proceed. I stripped the audio cable today and one wire already exposed and another which was insulated in white (as shown in the picture). What I'd like to know is which one do I use?

thanks

I think the white sheathed wire should be positive, the surrounding wire should be ground.

Thanks for clarifying this. It's CE aproved though which makes it legal in europe. Anyways, then the Iftron unit would solve the OP's problem then.

I only chose to make this big mount because I had ripped off the original 28mm mount. Something about high speed inverted pass.....still kind of foggy

This airframe was long ago retired and I needed a test bed for the FPV gear as I am completely new to this aspect of the hobby and didn't want to trash something else.

I believe the thrust angle is the same as stock but I will admit the Higher Verticle CG is a drawback.

Either way after this wreck serves its purpose all my FPV stuff is going on my Ritewing TL.

Indeed...and as noted earlier, even the lftron, I'm under the impression that if you change the antenna, you're required to have a HAM license...

Again, I know this is a legalese drill...and that we can always go for a HAM license or just operate without one...But that won't hack it with the AMA, FAA and FCC...

In a strict sense you are right, however if the FCC would have to go after every WiFi router user using an altenrative antenna....

Besides, CP antennas you get from a respected source will much likely be more resonant at the frequency band than the stock whips resulting in adhering better to the FCC rules. The CL and SPW also do not increase gain over the stock whips so you truly should be ok here.

Hello
I need a 2.4 Ghz rx/tx system for my FPV flying. I was looking at the Turnigy 9x from
hobbyking. I need a cheap one for less than 70 bucks. Later on I will buy a better one.
I need one that has the range of 2 km ( if possible). I need a cheap one because im 13 and I cant work yet so I get my money from my dad.
Thanks
