B is for Burbank – FPV Flight

One of my FPV goals was to fly around and take video of the big letter B in the foothills of Burbank and today I've met that goal! My flight times are about 12-15 minutes on 2 x 2,200 3S lipos, on my scratch-built J-Twin airplane (for more information about it click here). I'm using my FrSky Taranis and and extended range receiver, the new X8R and I had no problems with RC range. I was having some static and at around 1KM on my video feed, as I'm using an ImmersionRC 5.8 ghz 600 mW video transmitter.     route-m

J-Twin: Scratch-built FPV Platform

Introducing the J-Twin, a twin-motor airplane I designed and built specifically for FPV. I took it for its maiden flight today and I behaved amazingly well, just a click or two of aileron trim and it was all set. The center of gravity is approximately at 1/3 of the wing chord and it didn't present any negative tendencies. The plane is built using Adams Readi-board (dollar store foam) and balsa for the ailerons with reinforced packing tape for strength. The wing breaks down into 3 sections and it was built using the Armin Wing technique (from Ed, Experimental Airlines). Dimensions:
  • Wingspan: 60"
  • Length: 36"
  • Wing chord: 6.5"
Powertrain:
  • 2 x Turnigy D2630-11 1000 KV motors
  • APC 9 X 6 props (counter-rotating)
  • 35A H-King ESCs
RC:
  • FrSky X8R receiver
  • APM 2.5 flight controller
  • MinimOSD
FPV:
  • ImmersionRC 5.8 Ghz 600 mW Video transmitter
  • Fatshark RVC922 video goggles with built-in 5.8 receiver
  • GoPro Hero 2 for recording and video out.
Stay tuned for a flight video. Photo Gallery
