The is a tiny tiny coaxial aluminium frame helicopter with a gyro and infrared controller. A small vertically mounted tail rotor is used to provide fast forward and backward elevation.

Specifications

  • Motor: 2 solid motors for coaxial, 1 tail motor for elevation
  • Remote: Infrared, 3 band switch, 3 channels, integrated charger, 6x AA batteries
    • Controls: Elevator (for/aft), yaw (rotate), throttle (lift), and elevation speed (hi/low .5CH)
  • Battery: 60 mAh 3.7V (1-Cell) Lithium-Polymer
    • Charging connection on left-side
    • Charging: 20 minutes
    • To dis-engage charging mode, move throttle stick up and down
    • Runtime: approx. 4-5 minutes
  • Soft cut-off on low battery
  • Weight: 16.3 grams
  • Dimensions: 113x22x60mm (LxWxH)
  • Main rotor diameter: 110mm

Sanhuan documents:

Setup

  • For the first 5 flights, only run the battery down to 50%, 1.5 minute flighttime, it will help lengthen the life of the LiPo
  • If it swings or wobbles when in hover, try to fasten one or both blades (upper/lower)
  • Let the motors cool off after a flight, 5-10 minutes
  • Check the tail rotor for plastic residue left from the manufacturing
  • To enter forward flight mode, remove the tail fin, boom support, and skids, I think this is how it should fly by default! Weight: 15.1 grams
    • Optionally, bend the skid support screw-tabs down to raise the body above the on/off-switch sticking out. Note that the tabs will now catch most of the force on a crash and will eventually break off.
  • When on crash course, immediately push/kill the throttle to low to avoid unnecessary motor and blade wear
  • Avoid adding grease, tri-flow oil, or silicone oil, it seems to have an adverse effect on the flight characteristics
  • Its metal frame and general good design allows for an amazing amount of improper handling and crashing without much or any damage at all, 1.5m free-fall no problem

Possible tweaks

  • Mount small E-flite battery between the skids
    • Replace battery with higher capacity E-flite battery [1]
  • Removable battery with connector
    • Unsolder from circuit and use small connectors [2] [3] [4]
  • Improve cooling of the motors
    • Metal fins, funnel, thermal grease
  • Remove spring on throttle stick
  • Replace metal screws with nylon
  • Use higher quality LiPo batteries
  • Connect batteries in parallel for double capacity
    • E-flite BMCX/MSR 110mAh 1S 3.7V 3.4 grams [5]
    • OUTRAGE NRG15 3.7V 130mAH 15C [6]
    • ZIPPY 70mAh 20C 1S 1.5 grams [7]
    • ZIPPY 100mAh 20C 1S 3.0 grams [8]
    • ZIPPY Flightmax 138mAh-V2 1S 10C 3.7 grams [9]
  • Balance weight and flight performance
  • Disable LED lights
  • Swap controller trim-pot polarization
  • Program a better controller
  • Different size flybar weights
  • Swap the left and right control stick [10]
    • For Throttle and Yaw on left and Elevation on right
