Stryker-lite Build

• for flying slowly in more restricted space
• not expected to be usable in strong wind
• achieve robustness through speed reduction
• low stall speed
• "disposable" for worry free play

Questions

• should I just buy a slow-fly plane instead?
• where can I get EPP foam for winglets?

Final Design Details

New Parts Needed

• new battery + connectors
• motor
• ESC
• 2 x 5g servos
• depron or EPP foam
• magnets
• prop adaptor/saver
• many props

Ideas

• see one of the lite stryker threads on rcgroups - http://www.rcgroups.com/forums/showthread.php?t=530040

• fuselage:
  • remove "intakes" (-5g)
  • foam hatch cover (-25g)
  • no paint (-40g)
  • no fin supports - more lift? (-5g)
  • remove FG spars (possible?) (-10g)
• elevons - 3 mm balsa 50mm wide, possibly extended to prop area, cloth hinges (-15g)

• winglets - foam with magnet and cord --> lighter, reduced tip stall, protects elevons, can extend elevons to prop area for 3D (-20g)

• orange receiver w/o case (-10g)
• 5g servos (-10g)
• drive
  • battery 2S 1000mAh (-110g)
  • motor 100W (-40g)
  • ESC 20A (-15g)
  • large diam, low-pitch prop (slow-fly?) for thrust (-10g) (example: substituting GWS 8x4 for APC 7x5 on Stryker1 would give 15% more static thrust, 20% less top speed and same current and power)
  • prop saver mount (with sliced bladder for bands)

• total weight reduction: 5+25+40+5+10+15+20+10+10+110+40+15+10 = 315g --> ~ half stock weight
