Tips

  • Center of gravity 50-55 mm from leading wing edge, on wing spar rods, 56 mm minimum drag [11] [12] [13] [14] [15] [16]
  • CG perfect with 3S 2200 mAh battery, a 1300 mAh is tail heavy, need to expand the room for the battery
  • First flights, best to set up CG as far forward as possible and a little noise heavy then tail heavy [17]
  • Change prop to 6x4E for more efficient flight, avoid going over 18A on stock motor and ESC combination [18]
  • Replace stock 20A ESC for a safer more capable 25A or 30A, using a higher rated ESC than necessary will run inefficient, less flight time although cool ESC, now comes with 25A ESC stock
  • Get an ESC with +10A over the maximum amperage for the motor [19]
  • Fasten the battery and canopy properly to allow rolls and loops without loosing parts
  • Add fiber reinforced tape to the bottom of the plane to ease landing on rough surfaces
  • On stock motor, re-glue magnets with epoxy or CA glue after a few flights
  • Use a rubber-band and mount, magnets, or velcro, to keep the wings tighter together [20] [21]
  • Mount the propeller the right way, the concaved or inward bent curve of the propeller should face the tail, text the front
  • The text must face toward the front, or on pusher propellers to the back [22]
  • If propeller is mounted the correct way but rotates the wrong way, swap any two of the three motor wires between the motor and ESC
  • Cut off excess length of the push-rods to avoid poking holes in battery or ESC
  • During launch, use 45-50% throttle, trim elevator down a few clicks or program flap-switch to 15-20% elev up to avoid diving, hard throw 20% up into the air, clear elevator up trim [23] [24] [25] [26] [27]
  • Use blue threadlock on push-rod connectors and any metal to metal screws or nuts
  • Use threadlock on all screws on the motor and motor mount [28]
  • Loosen up the foam on rudder, elevator, aileron hinges, or cut them off and re-attach with packing tape
  • Use 3M double-sided tape to fasten and packing tape to cover the aileron servos, easy to remove for later repairs
  • FPV: video transmitter on the tail, OSD under wing fuselage, camera on canopy, 1800 mAh battery
  • Pick a small enough propeller to allow the motor to run efficiently, avoid overloading and burning the motor, use WebOCalc [29]
  • Change the prop-saver for a collet-adapter, less vibration, prop-saver not needed on pusher plane [30]
  • Straighten crooked foam by dipping it in hot water, not boiling, and reform it by hand, use spoon for any pimples [31] [32]
  • Mix 30-50% rudder into aileron on the transmitter for tighter corner turns [33]
  • Set-up throttle-to-elevator mixing on Tx, -15% to stay flat on all throttle positions [34]
  • Mark the wingtips with red decals/tape to easier identify the orientation of the airplane against the sky
  • Always take-off against the wind and the same for landing, against the wind as lower landing-speed requires more lift to avoid stall
  • Use the inner-most hole on the wing-horn and the outer-most hole on the servo-arm for maximum throw [35] [36]
  • To make the plane less reactive/twitchy for beginners, use push-rod on inner hole of servo and outer hole on the control horn, can also be range/exponential limited on transmitter [37]
  • Flaperons can help to make landing and launching easier, more angle of attack for resistance and decrease airspeed, replace Y-cable by two seperate aileron channels, programmed by the transmitter, spoilerons are flaperons inverted up [38]
  • Thrust line should pass through both the center of mass and the center of drag [39] [40]
  • Motor pod should have an angle pointing through the center-of-gravity point, called thrust line, to minimize elevator pitch down effect when throttling up the motor [41]
  • For prop-saver, attach the o-ring around the prop and to the 2 grub screws straight no crossing, more centered this way [42] [43]
  • Change the motor if the motor begins to vibrate during testing and propeller is balanced, motor is unbalanced [44]
  • To keep the same ESC current draw, when going up in prop size go down in motor Kv [45]
  • Throws: aileron 10 mm up or down, use outside hole of horn, elevator 5mm up or down, middle hole, rudder 20 mm both ways, middle hole [46] [47]
  • For maximum aileron throw, adjust travel on transmitter to 140% and cut a dent in the EPO at the edge for the servo arm and push-rods [48]
  • Turn the servos around with the head pointing to the rear, frees up servo arm movement and avoids binding on max down, easiest accomplished by swapping right with left servo
  • Add a gyro to aileron for more stable flight in windy conditions, will give minimum roll effect on rudder input, use fast servos [49] [50]
  • Use a gyro on elevator (pitch) to make landing easier in gusty wind conditions [51]
  • On a 45 degree dive and 1/4 throttle, release elevator stick, plane should level back, tail heavy if continuous dive and nose heavy if alternating climb/diving bumping [52] [53]
  • The thrust-to-weight ratio is 1:1 when a motor generates the same thrust as the weight of the plane [54]
  • Minimum 1:2 static thrust to weight for leisurely flight, 1:1 for aerobatics, and atleast 1.4:1 for 3D and hovering [55]
  • Wrap ferrite ring on BEC power lead to receiver to eliminate high frequency current noise from the ESC, 5-7 times round, helps wobbly lines on FPV cameras [56]
  • Propeller dimensions, e.g. 6x4, means that the diameter (length) is 6-inches and the total distance traveled for one rotation is 4-inches [57]
  • Increased prop-pitch gives increased speed but poorer acceleration, increased diameter increases thrust and current draw but lowers RPM and speed [58] [59]
  • Flatten wing tips or shorten them for better rolls, speed and agility, it decreases the dihedral effect [60] [61]
  • Desolder cable between ESC and motor to add 3.5 mm bullet connectors with heat shrink, easier for repairs and to replace ESC
  • Enable air-brake on ESC to stop propeller free-turning on no throttle and gliding, will draw small amount of current [62]
  • Put the two Y-cable connectors in the square space between the wing halves [63]
  • For a more stable elevator, make a groove on the underside and put a 3-4mm carbon fiber rod from tip to tip, use any type of CA glue, perhaps while tape on top [64] [65]
  • Balance propeller using a magnetic bearing propeller balancer, add thin tape to the back of the lighter blade of the propeller or sand the back of the heavy side, not the tips [66]
  • ESC setup: motor brake ON, battery type Lipo, battery low cut-off, cut-off voltage high (3.2V), start mode normal, timing mode high, govenor mode off [67]

ESC Setup

  • Air break: On (Hold propeller still)
  • Battery type: Lithium-polymer
  • Cut-off type: Softcut (Gracefully lower motor power)
  • Cut-off voltage: High (3.1V)
  • Start mode: Normal (Instant acceleration)
  • Timing mode: Medium (Balance rpm and efficiency) / High (12+ pole motors)
  • Lipo cells: All off (Auto detect)
  • Governor mode: Off (Heli only)
  • Swap 2 of the 3 motor wires to reverse the motor rotation
