Skyburners Micro Yak R2

OK, this has been a very rewarding project and it flies great. I recently started a revision of the first prototype with a few goals, primarily weight savings related and tweaks to make it more survivable in a crowded indoor gym.
  • Pull Pull setup, eliminating the carbon control rods.
  • AR6300 with micro connectors & 3.7g servos
  • Drag Plates
  • EPP on the nose to improve survivability
  • Complete rework of the vertical milling
  • Gentle tweaks to the profiles
  • Tighten the slots for snug fitting.
  • Little color this time now that I know it will fly good
The primary goal of making a micro/near-micro indoor plane that still felt like a larger plane without the squirrelly-ness of the ultra micros out there currently. Capturing a hybrid of pattern and 3D was another of the major goals.

SPECS:
  • 23.2"/588mm WS
  • 25"/640mm
  • AUW: 80g
  • Dry weight: 66g
  • Hyperion 25c 2S 180: 13,6g
  • Alternate is the TP Pro Lite v3 250 2s (17g)
  • 3 3.7g servos (unmarked-same as RCTimer ones)
  • AR6300 used with DX6i
  • Pentium 6A ESC
  • HobbyCity 18-11 2000kv Micro Brushless Outrunner (10g)
  • GWS 5030 prop
  • 3mm EPP doubler CNC cut
  • 3mm Depron milled CNC cut
  • Radical RC biased control horn
  • UHU-POR and Mercury Foam Safe assembly.
  • Gorilla White on the doubler and epoxy to mount the lite-ply motor mount

Skyburners Micro Yak (4 min 53 sec)



Please forgive me if it seems like I am showing off, this plane is awesome for its size!

Swapped the 18-11 2000kv with the GWS5030 out and put the 1306N 2200kv 9gr on it. Made quite a difference in performance. The 2000kv showed its inefficiency shortly into flight and had to use 90% throttle to break hover. The 2200kv on a 6030 did a great job at maintaining thrust and have head room left over for punch out, even after 5 minutes of flight time! Definitely recommend the 1306N for this weight class.
