Durafly P-40N from Hobbyking – 1st Impressions & Assembly

Presenting Hobbyking’s newest model airplane from the Durafly line, the Curtiss P-40N Warhawk. I ordered it the day it came out from the US West Warehouse (click here to get yours) and received it 4 working days later, via FedEx ground. Here is my first impressions and assembly video.

I am really impressed with the details, the paint job and the ease of assembly. Not one drop of glue is needed (except for the small plastic details). It comes together really quickly thanks to the easy-to-follow instructions, the labeling of all the servo leads and the plastic bags that have the different types of screws. Assembly took about an hour and installing the decals with probably take another 30 minutes.

Overall, I am really please with the airplane. Stay tuned for the maiden flight video!

  • Well built, solid construction
  • Flies stable, but quick and maneuverable if in high rates
  • Flips and rolls are crisp and precise
  • Shipping to 9 days (China – California)
  • Only $20.75


  • Remote is kind of small (but standard for this size multi rotors)
  • Need a screwdriver to install batteries in remote
  • LEDs aren’t very bright

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
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!
