Before we begin
- Please read this manual carefully!
- The frame is always flown in “X” configuration. Make sure you switch/set your FC to fly in “X” mode.
- As of version 1.2 of the frame, the arms now have threads that enables you to screw them to the frame with 4 M3x5mm button head screws.
Check your package contents to make sure you have all the parts. Your parts may show some scuff marks or minor scratches. That is expected and nothing to worry about.

Assemble the Bottom “Dirty” Frame
Begin the build by taking the power distribution board (“PDB”) and solder the ESCs to the connections marked by “ESC1″ through “ESC4″. Make sure you solder all the red wires to the “+” pads and all the black wires to the “-” pads. You want the power cables to be fairly short. Take a look at the picture below. While the picture shows 3.5mm bullet connectors for the ESC to Motor connections, the better way to assemble the frame is by soldering the motor cables directly onto the ESCs. This will save you a lot of build time if your motors and ESCs don’t already come with bullet connectors. It also will remove one of the key failure points on any multi-rotor. Bullet connectors can loose connectivity or one of the many solder connections can get weak and fail. If you do solder the motor wires straight onto your ESCs, make sure you shorten/lengthen your motor cables to an appropriate length and that you test each ESC/motor to ensure the motor spins in the right direction for where it will be located on the frame.
Solder a lipo pig-tail to one of the pads with the “Bat1″ or “Bat2″ labels. Turn the PDB so that the pig-tail comes out on the side that will work best with your lipos. If your lipos have the power leads on the right side, make sure the pig-tail comes out on the right side as well. You can solder a pig-tail to both battery connections if you want to fly with 2 batteries in parallel. You can attach the pig tail with a zip tie to the PDB. This ensures that in the event of a crash the pig tail will not be ripped off the pads and damage the PDB.
Other Power Leads
The PDB of the QAV500 provides you many additional power pads. Use these to attach power leads for your FPV equipment, lipo meters, sensors, cameras, LEDs, etc.
Frame plate sequence
The entire frame has this sequence of frame plates, starting from the bottom:
- G10 “Dirty” frame plate
- Arms, ESCs, and 10mm aluminum spacers
- PDB (with the soldering pads facing inside)
- Orange RC Bobbins
- Long base of the “Clean” frame part
- 35mm aluminum spacers
- Flight controller and auxiliary battery mount
When securing the aluminum spacers with the included 6mm screws, make sure you use thread-lock to secure the screws.

Vibration Mounts (“Orange RC Bobbins”)
The Orange RC Bobbins are a vital part of the proper functioning of the QAV500 frame. We are now including regular M3 nuts that are much easier to attach to the vibration mounts than previously included ‘lock nuts’. Attach the bobbins with the regular nuts to the assembled ‘dirty’ frame. Then attach the ‘clean’ frame on the other side of the Orange RC Bobbins. When tightening the nuts, make sure you do not twist the orange vibration material!
Placing your lipo
The lipo is placed on the back of the frame either into the cavity between the long “clean” base and the flight controller cover, or on the top of the flight controller cover. The lipo is secured to the frame with the use of the included ‘fpvmanuals’ lipo strap. The included lipo strap is a special rubberized strap that does not require you to use use any velcro stuck to the frame or your lipo. You want to avoid using velcro as it would require you to rip your lipo off your frame when you want to swap lipos. This forceful removal of your lipo when using velcro can damage the vibration bobbins. The use of the this high-end strap makes lipo changes quick and easy and also protects your frame and vibration bobbins.
Center of Gravity Optimization
The center of gravity (CG) is located right in the center of the frame. You can easily find the CG by looking at the bottom of the frame. The CG line is located where the Lipo pig-tail attaches to the PDB. See picture.
To mount a GoPro and flight cam, you should attach them as in the below picture. A flight cam with a little mounting bracket works best as the frame has a mounting hole for this bracket. Under the GoPro use a small strip of the included Neoprene tape on the left and right side of the GoPro. Do not place a big strip of neoprene tape under the entire cam as you want to minimize the surface area that connects the GoPro to the frame. To attach the GoPro well, we recommend you use Velcro brand Qwik tie that is 0.5″ (12.7mm) wide. This velcro is thin and flexible. you can buy it as cable ties and larger rolls that are good to have in your workshop. The smaller cable ties are available here and long rolls are available here.
The down camera is position on the tail of the frame, under the lipo. Use a strip of velcro to attach the GoPro to the frame. Place a small strip of the included neoprene tape onto the frame on the left and right side of the GoPro (maybe half the thickness of the tape).
Achieve vibration free 1080p recordings
The QAV500 was specifically designed to record vibration free, crisp 1080p recordings. To achieve this, a few things are important for the build of your QAV500.
- Use 10″ props. The frame is tuned to fly with 10″ props. If you use larger props like 11″ the video image will most likely have vibrations in your picture as the harmonics produced by 11″ are different than those produced by 10″ props.
- Use high quality props. We recommend Graupner E-Props 10×5.
- Balance your props. All props need balancing, including Graupner E-Props. If you don’t balance your props, your frame will not fly as well as when you do properly balance your props. Some pilots have reported vibration free 1080p footage with the QAV500 even though they did not balance their props. Hover, the performance of your frame will always be improved when balancing your props. It only takes 5 minutes and is a critically important step you should not overlook.
- Avoid using props or motors that were in a crash. A motor that was in a crash has a high likelihood of having been damaged. The shaft could be bent, the bell slightly out of true, the ball-bearings could be damaged, etc. While some damage might not be apparent, if your QAV500 video has vibrations, the cause is likely a damaged motor or prop.
Carbon Fiber Landing-Gear
If you purchased the optional carbon-fiber landing gear, please see the below picture on how to assemble it and attach it to the arms. It’s important that you apply even force on each of the two set screws. Also, take care not to over-tighten the set screws with the included allen key. The clamps holding the carbon fiber tubes are made of aluminum which is a soft material that can easily strip.
