VEKTOR 280 RR FPV RACING DRONE (Free Shipping!)

Lot of Quad for the Price

Posted by XionUAV on 16th Feb 2018

There's always some concern when purchasing a product that has an integrated control and power system because a failure of any one part renders the entire aircraft useless. That said, the Vektor is very high quality especially for the price.

The CC3D FC has to be flashed with new firmware as per included instructions so it isn't ready to fly in that regard. While the instructions don’t specify this, you need to go through the LibrePilot vehicle Setup Wizard to properly setup the quad. I first tried going straight to individual configuration screens which caused problems. There will also be several other sections to program settings and flight modes and such so again, not a quad for someone expecting to just buy it and fly it.

Mine would oscillate at hover so I increased a parameter called gyro noise filtering that helped reduce this oscillation. Yaw stability still doesn’t seem as solid as it should be so I’ll still have to play with that. It flies well otherwise.

Clearance between the supplied 6x4 props and battery wires was a concern so I replaced the props with 5x4x3. The camera was subpar for me so it's getting an upgrade. The provided camera is PAL so if you want NTSC you’ll need a different camera away.

Another issue that isn’t isolated to only this quad is motor “twitching” when the ESC’s are set for OneShot125. This happens even when disarmed. In order to stop the twitch the MIN values on the motor output screen need to be reduced to 960 from 1000 to eliminate the twitch completely.

Now I realize this quad is being clearanced at a great price so nitpicking is pointless, but there are some other things to point out just FYI. One is the lighting. There are 6 led lights under the frame that can be programmed for different brightness and patterns. Problem is they’re mounted to the inner plate and shine through cutouts on the bottom plate and a little off the side. Hard to see well and can’t be disabled from what I can tell so I just programmed mine to flash once at the slowest interval possible to reduce battery consumption. Plus the battery strap goes under the frame and covers up the center LED’s anyway.

There are two jumbo green LED’s on each side of the fixed XT60 on the back to warn of low battery. Problem with these is they appear to be programmed to flash when battery voltage is around 10.5V on 3S. Maybe that’s common for racer boys but most of us “normal” pilots prefer not to drain batteries below 3.6V per cell. So I attached a voltage alarm to the bottom of the frame at the back to read battery voltage. Only other nitpick is a couple of the holes to mount the canopy weren’t centered and needed minor milling and the front of the canopy doesn’t clear the frame where the camera support is so that needs some minor work as well.

The video transmitter channel switches are located on the top of the control board on the inner plate. To change them the top plate has to be removed. So once they’re set that’s it unless you remove the top plate or cut an access hole in the plate.

Another issue I ran into that had nothing to do with the quad itself is I couldn’t import the Vektor vehicle profile into the software for some reason. Had to manually find the LibrePilot multirotor profile directory and add the profile to that directory in order to load it into the FC.

So for a nice looking, cheap little solid, high-quality quad to tinker and have fun with it’s definitely worth the work to setup.
