SubMini 200mm FPV Quad

Introducing the SubMini 200mm FPV quad, a custom designed multirotor. As the name indicates, is has a motor-to-motor diagonal measurement of 200mm, perfectly suited for 4″ props. The frame was designed and 3D printed in black ABS and is 4mm thick.

Components (with links).

Motors: RCX 1306 2300kv
Props: 4045 CW & CCW from MyRcMart.com
ESCs: RTF HUGESC 12AMP SIMONK-(RAPIDESC)
Flight Controller: Flip32 Racing Edition
RC Receiver: FrSky VD5M
FPV Transmitter: TS5823 5.8GHz 32CH Mini FPV Video Transmitter
Camera: RunCam PZ0420M 2.8 mm lens
Battery: ZIPPY Flightmax 1000mAh 3S1P 25C
Antenna: Off-brand CP RP-SMA antenna.

Here’s a quick rundown of the costs, but please note that not everything needed is included: I already had 4 batteries and the FPV antenna. Also, its a good idea to get a spare motor and ESC, just in case. You don’t want your project to be halted because of a faulty motor. But, on the positive side, Shipping from MyRCMart was suprisingly quick: the package took exactly a week to arrive from China to my doorstep in California.

Soldering the HugESC wires was a bit tricky, you need a fast and steady hand. The ESCs where shrink-wrapped to the frame itself for additional protection.

Frame and ESCs

I was initially going to use a regular Flip32 fullsize controller, but the spare one I had wasn’t working quite right, so I ordered the Flip32 Racing controller, which is less than half the size of a standard Flip32 (35mm x 35mm). I decided to use the FrSky VD5M because it was what I had lying around, and it worked quite well. I removed the connectors and soldered the wires directly from the receiver to flight controller. Again, you need a fast and steady hand to pull this off, the solder points are tiny. I epoxied the receiver wiring to ensure durability.

The 1306 motors are tiny! They are really 1706 (17mm in diameter), but they perform quite well when paired with 4 x 4.5 props.

1306 motors and 4045 props

The all-up-weight (AUG) is 246g (165g for the frame alone). It was tuned and maidened at night and it was a blast to fly, going inside the house and over the sidewalks while I just stood there in the garage. Flight times are about 4-5 minutes of fast FPV flying, a bit more if you’re just cruising.

Overall I’m very happy with this SubMini quad, which is what I’m going to call it, since it is smaller than what is considered a mini quad (250mm) and not quite a nano or pico quad. So, SubMini it is!

The Ghoul Part 2: Assembly – Building a better Phantom

Here’s part 2 of the Build a Better Phantom Series: a quad with T-Motors, SimonK ESCs and an APM Mini flight controller in a Phantom shell: The Ghoul. Please visit the first part of the series to get a list of components by clicking here. Here are links to additional guides and documents needed to complete this build.

Un-official guide: Mini APM from Witespy

Light module pinout and info

In part 3, I’ll show you footage captured on the Ghoul during the maiden flight and a lazy adventure around my local park (as soon as I figure out how to process video shot at 120fps). Stay tuned!

Custom Designed 3D Printed Y6 Multirotor

Introducing my custom designed and 3D printed Y6 multirotor. After many hours of designing, printing, troubleshooting and test flying, I am finally showcasing my latest multirotor with the world. The frame base, motor holders, landing gear and 3-axis gimbal were printed 3D printed in ABS. The booms are carbon fiber tubes that are 330 mm long and 16 mm in diameter. Here are some additional specs:

It features a 3 axis gimbal that uses the following:

Stay tuned for flight footage of the Y6 flying and gimbal stablilized footage from the GoPro / gimbal.

Swift Hex – 300mm 3D Printed Hex Frame

Introducing the Swift Hex, a mini sized hexacopter that I designed and 3D printed, specifically for FPV. Its design was inspired by the Blackout Spider Hex, but seeing as it is currently unavailable, I decided to designed and make my own.

3d-design

It is exactly 300mm motor to motor. It uses 37mm spacers, just because that is what I had lying around. I decided to use cheap ZMR 1806 motors, along with 5 x 3 props. It has a built-in vibration dampening system with earplug for the top-mounted Mobius Action Cam. 10amp SimonK ESCs and a Naze32 equivalent, the Flip32+ from Witespy power the system.

The first version was made with 5mm plates, but the second (and final flying version) was made only 3mm thick and the bottom, center and top plates were specifically redesigned for load bearing, stiffness and better looks. It has 2 cameras, the aformentioned Mobius Action Cam wide angle for recording and a PZ0420 Clone for FPV.

The final version FPV version has the following specs:

– 2450mah Zippy Compact 35C 3S Lipo
– ImmersionRC 600mw Video transmitter and protector
– FrSky DR4-II and Taranis for control
– ZMR 1806 motors
– HQ 5×3 props
– 10a SimonK ESCs
– Flip32+ flight controller

Future plans include adding a GPS and a MinimOSD to the flight controller.

Here’s the video of the maiden FPV flight of the Swift Hex.

Scratch-Built Turbo Commander

The (Gulfstream? Rockwell?) Turbo Commander airplane has always had a special place in my heart; it was the plane my dad and his pilot friends used to fly. Its a twin-engine, pressurized, jet-prop 10-passenger airplane, better known as Bob Hoover’s acrobatic plane (his was a Shrike, a piston-powered Aero Commander variant).

TC690BII-11544

Over the holiday season, my friend Mateo and I decided to build a scale version of this plane, using a blown-up 3-view picture I found online.

turbo-commander-690-dims

It was built using a combination of Adam’s Readi-board and pink 1″ insulation foam. The whole process took about 4 nights.

Additional specs:

  • 60″ Wingspan
  • 55″ Fuselage length
  • 2 x Turnigy D3536/8 1000KV
  • 2 x 9 x 6 APC props (CW & CCW)
  • 6 9G servos (1 for stearing, 1 for rudder, 2 for ailerons and 2 for elevators).
  • 2 x 50A Hking ESCs
  • 3,000mah 4S Turnigy Lipo
  • FrSky X8R receiver.

Check out the gallery below which shows the build process. Stay tuned for the maiden flight video.
