Description

This high speed configuration is based on the famous Sonicmodell AR Wing and has been flight proven for many hours. With INAV correctly tuned it flies extremely stable and although the weight is relative high (what helps for stability), it does easily launch and is extremely agile. The plane is also perfect for chasing other planes with a very wide speed range and it’s a great proximity flyer for gaps and low altitude passes. So use this guide to build your own high speed AR Wing.

For this setup it is recommended to make the stock airframe more rigid to remove the flex from the ailerons at high speeds. So we have glued some 3x1mm carbon stripes to the trailing edge of the ailerons with foam glue and added sticky lamination foil over it. This prevents any flexing. We also added 5x1mm carbon stripes on the wing bottom in front of the ailerons, that are placed from the middle wing out to the tips, so the wingtip does not flex either. The last addition was another 5×1 carbon stripe that we put horizontally inside the leading edge of the wings, covered by a layer of fiber glass tape and an extra layer sticky laminate. This makes the wing extremely impact resistant to not get damaged by branches or crashes. To mount the Motor, you can use the stock Mount-Cross but you can only use 2 of the 4 screws. Secure them with some loctite. That’s fine and will hold up well.

To reach top speeds we have used the thin wooden winglets shipped with the airframe. To prevent them from easily breaking, we also put thin sticky lamination around them. You can see a crash in the video below and at the end that has been easily survived with just a few cracks in the unprotected main body but no damage on the wings.

  • EMAX ES08MD II Servo

    EMAX ES08MD II

    The EMAX ES08MD II is a decent quality mini servo. It has all metal gears and a torque of >2 kg.cm. This servo can run on 4.8 to 6 Volts.

    This servo sits in the “9 g” mini servo category. It actually weights 13 g due to the metal gears. Testing this servo has shown it to perform better than the specs on the box. It is also slightly shorter in the body than the average size mini servos like the MG90’s.

    Foxeer Lollipop 3

    The Foxeer Lollipop 3 is a light weight, 5.8 GHz, circular polarised antenna. It weighs only 3.7 grams, has a gain of 2.5 dBi, and a VSWR less than 1.2.

  • Holybro Tekko32 F3 65A ESC

    Holybro Tekko32 F3 65A

    The Holybro Tekko32 F3 65A is a BLHELI_32 ESC with an F3 MCU for smoother control and a faster response. This ESC can handle a 65 Amp draw continuously, or a burst up to 80 Amps.

    The Holybro Tekko32 supports 3S-6S LiPo. Though, if you are running 6S; you will need to use the provided 220uF 35V capacitor. For the power rating, this is a small ESC, measuring only 27×18 mm.

    Matek F411-WING

    The Matek F411-WING is a small, lightweight flight controller, well suited to small planes or flying wings. It has an overall size of 41×28×10 mm and weighs only 12 grams.

    Because of the size, there are compromises. For instance, there are only 2 UARTS available on this flight controller. There is a Softserial port, and also an alternate firmware target which enables a second Softserial port by sacrificing the LEDs. The servo BEC is switchable between 5 and 6 Volts; it has a continuous rating of 3A, so is safe for 4 servos.

    There is a downside to this flight controller. The VTx power it a VBAT pad on the board. It has no filtering so can be very noisy. It can be improved using capacitors and an LC filter. But it’s something to consider if you are looking for the ultimate in light weight. While on the subject, the new Matek F411-WSE has really superseded this board. Not only does it have filtering on the video power. But it also has switchable dual camera inputs, 4 ADCs, and it is 3.5 grams lighter.

    Matek VTX-HV

    The Matek Systems VTX-HV is a 500mW 5.8GHz VTx. It has mounting holes for a standard size 30.5mm stack. The antenna connects with an MMCX connector, which is a nice compromise between reliability and weight.

    The VTx can be configured using Tramp Telemetry to any of the 40 channels and power levels (25, 200, and 500 mW). This VTx can also have its firmware upgraded using the onboard UART.

  • Racerstar AirB Motor

    Racerstar AirB

    The Racerstar AirB is the second motor to come out of the partnership with Racerstar and T-Motor. These motors are well designed, look fantastic, and also feature quality components.

    If you have bought Racerstar motors in the past, and found the to be pretty shoddy; you will at first have a hard time believing that these motors are from the same company. Both the AirA and AirB are great motors. So the involvement with T-Motor has definitely shone through. The machining, bearings, windings, and overall finish are all top notch.

    The AirB is a 2514 stator motor with a KV of 1498. It can run from 3S all the way up to 8S, with a maximum power of 1139 Watts or 45 Amps. Suggested props are 4S – 8″, 5S – 7″, 5S & 6S – 6″ tri-blade, and 8S – 5″ tri-blade.

    SonicModell AR Wing

    The AR Wing by SonicModell is a versatile, 900 mm flying wing. You can use the AR for multiple roles including long range and as a pretty quick, fun flyer.

    It is also a good choice for beginners, due to its ease of build and good stability. The bay is spacious, giving lots of room for battery and component options. There’s also an HD camera bay, which can be reconfigured for different cameras, including the GoPro Sessions and RunCam 2 style cameras.
