Hey guys, having played with cheap store bought micro quads for a while I am looking to step up and build my first 250 FPV/aero quad. I am going to use it as a learning tool both for building and flying before getting into some of the bigger camera platforms.


I have trawled the net and forums for a while and have come up with this parts list. I would appreciate any feedback on the setup and tips for the build.


Frame: Hobby King FPV 250L or a ZMR 250 carbon clone

Motors: 2150Kv Baby Beast

Props: 2 blade 5030 Gemfans

ESC: Afro 12A

PDB: Hobby King micro PDB

Flight controller: Cant choose between the KK2.1 and Naze 32

Battery: 1300mah 45C+ 3S

Tx: My old JR Max 66

Rx: FrSKY TFR6 7ch FASST


FPV: I am still not sure sure about this side of things and any recommendations to go with the above setup would be appreciated.


Cheers
 
Thanks for the links to the videos. I have seen a few of Bruce's other reviews and on the basis of this I have finally committed and placed my order. Now a few weeks anxious wait before the real fun begins!
 
Hi Friend.
I have done more or less the same build.
CC3D flight controller is a good bargain as well.
Have have the ImmersionRC 600mw vTX and the Fatshark Goggles. Works fine!
 
Wow this has ended up being no way near as much fun as I thought. After enduring Hobby Kings infamous customer service and after 4 months of getting stuffed around I ended up ordering most of the stuff from rotor geeks. A friend convinced me to fork out for the new Taranis plus Tx and ditch my old max66 but now I have a bind...or lack there of.

I am running the naze32 board and have both a X8R receiver and a lemon-rx 6ch feather lite. I am completely stuck at how to connect either to the Naze and I cannot find any clear instructions on the net. Is there anyone out there who can help me out and preferably share some photos?

Cheers
 
Hi mate FCBs are FCBs ,they are very much the same as they need signal in from the receiver then have to put out signals to the motors ,
use an ESC to power the receiver and bind to the transmitter , once this is done wire up the nase go from receiver to the FCB input pins , then wire the motors up to the motor pins of the board look at page 5 , now if your using cppm your only have signal wires if your going standard then each servo plug will have 3 wires , let me know what why your going

Thanks mate. Yeh I have it all wired in via a PDB and I am getting power to the both receivers, it primarily seems to be a binding issue. Once the TX and RX are talking then the servo leads should be self explanatory (i think). I have had another shot at the lemon DSM2 and I have followed the online tutorials but only seem to get the flashing red LED showing its looking for a bind. Where I am fuzzy is how the TX and RX talk and get a little lost with DSM2, DSMX, CPPM, SBUS etc and possibly the settings for the Taranis which I have only been playing with for a couple of days.
So i guess in summary I can power both the lemon feather light and the X8R but I can't bind them to my Taranis - any pointers?
 
Hi mate what module do you have in the back of the transmitter?
Dsm2/dsmx are spektrum protocol, sbus and cppm it the way a receiver can send all transmitter signals down one main wire and then splits in to the 6 channels
 
Ok this is starting to make more sense. I have just the basic taranis plus transmitter (no spectrum back pack) which explains why the lemon rx isn't binding. So now I just need to figure out how to connect the x8r with the naze
 
Just Bind the receiver first so thats working , then are you going full wires as standard or cppm single wire , In the manual it show connections for both so once you know what way your going to connect then just stick to that part of the wire connections
 
Thanks Holtneil, after almost 8 hours I have finally got the quad up and running and I have to say I am very impressed with its performance. It has been a much steeper learning curve than I anticipated and I am still playing with the PIDs but its immensely satisfying to have it up in the air after this long.

The final step will be sorting out my FPV gear and I am after a bit more advice on this. I have decided to go with screens over goggles for now and I am happy with my camera but I am not so sure about my ground station. Initially I was going to get a screen, mate it with a battery and rx however I have seen a few all in one FPV setups lately. The black pearl seems to be the pick of the litter but it seems to have some range issues. Has anyone had any experience with this?
 
Thanks for the advice. I ended up getting an all in 1 package which included a TS58500 VTx, RC832, some basic goggles and appropriate wiring and antennae. I have set it all up and added the power before I finally install it and finally compete my build. Of course though I have hit a snag in that I can't seem to power the VTx. There is a red LED built in which does not turn on when I plug it all in I. I soldered my own Power filter so I thought that could be the problem however using a spare 5 pin lead directly to the battery I still can't get the LED to light up. Any thoughts?

Having since sorted out the purpose of the balance wires on the battery I have re-weired the whole thing off the PDB and still no luck. Having fried a couple of servo wires I was using for testing I hope haven't cooked the whole system.
