  • Weight: 59-62oz (1.67-1.75kg) CG 30-35mm behind servo wiring slots.
  • Motor: Scorpion Scorpion SII-3008-1220KV (V2)
  • Prop size: APC 10x6 folding with MAXX 40mm spinner adapter for 5mm shaft
  • ESC: Scorpion Commander 55 under wing w/ vent hole in side of fuse. Its built in BEC powers RC Rx and 6 servos
  • Separate BEC: DPCAV any2any + DPCAV LC filter supplies 12V to Vid Tx, and Turnigy 3-5A BEC supplies 5V to camera and mic.
  • Servos used: HS-65MG all around. Also used bevrc's little MG servos and they're fine
  • Single flight & video battery: Hyperion 3S 25C 4000-5000mAh.
  • Cruise minimal consumption: 6.5A (about 75W)
  • Max speed: 50-55mph
  • Max flight times: 30ish min on a single 4000mAh battery, but usually burn through it flying faster in about 18-20 minutes.
  • RC LRS: TSLRS or TSLRS Pro or Rangelink UHF
  • RCRX: TSLRS LR Rx with a couple 3300uF caps to buffer the power so it'll play nice with my Hyperion digital servos on P&T.
  • RCRX antenna: stock
  • RC RSSI indicator: dpcav RSSI LCD screen, mounted where I can look down at it with flight cam (no OSD) Needs 6V power.
  • Flight cam: RCV922 (or here) on full homemade pan & tilt with head tracking
  • Recording cam: GoPro Hero2 1080p medium wide angle on pan servo Y'd off flight cam's pan channel
  • VTX: Sunsky FOX800 (about 600mW) 1.3Ghz
  • VTX antena: Simple homemade Vee (formed from core and twisted/soldered shield ground) high on tail. Alternate BlueBeam Cloverleaf
  • VRX: Standard single A/V output 4ch Racewood 1.2-1.3Ghz Rx with SAW filter mod. Much better selectivity than cheap Sunsky 12ch Rxs which do not work with UHF RC Txs nearby.
  • Diversity (when used): Oracle
  • VRX antenna 1: Re-tuned 1.2Ghz to 1.3Ghz (makes *huge* difference) L-COM 8dB patch, or 3 turn 7dB Helical CP
  • VRX antenna 2: omni SPW or Virevent
  • Ground station battery: Any big 3S battery. Use old puffed ones that still deliver full capacity but only at low current.
  • Video distribution:Whatever diversity provides + OnVon 5 way powered video splitter (been extremely reliable). Also often retransmit on 5.8Ghz to 2nd Fatshark 5.8Ghz goggles.
  • Flight recording: Lawmate PV-1000 DVR and Aitptek MPVR+CB (aka DV5800) as backup. FPV-Japan and clones are proven alternative.
  • Flight control viewing: wired Fatshark Aviator (old 2.4ghz version that I use A/V in), and sometimes new 5.8Ghz Fatshark Aviator - powered off cheap 2S 1000 Lipos
  • Flight backup viewing: Lawmate PV-1000 has a nice big screen

Don't forget what kind of battery you are using.

Not sure of weight, but mine is probably heavier than most.
Turnigy Plush 80 Amp (Way too big but it was on hand)
Moxie 980KV http://www.lowpricerc.com/product_in...roducts_id=991
9x6 prop (I've used APC slow fly and electric prop, can't tell difference)
4S 5000mAh for motor

I can launch easily at 20 Amps, cruise at around 4-5 Amps


Also of note. I've tried this setup with a 3S battery and it was kinda wimpy but my batteries were old and wimpy as well.
I have significant problems with my current setup and RVOSD vibrations. Looking to buy a better motor to help solve this and get back to a 3S setup.
