Scratchbuild (STOL) Carbon Cub SS - built with carbon fibre tubes

After scratchbuilding a balsa Super Cub, it's time for the next one. A Carbon Cub SS. Also based on Ed Westwood plans which are slightly modified for the occasion.

Characteristics, general:
  • As light as possible.
  • Wingspan about 110 cm, some 43".
  • Length about 75 cm.
  • Weight should remain below 450 gram.
  • Same paint scheme as the example.
  • Cowl will be a challenge...

Characteristics, fuse:
  • As light as possible.
  • The fuse will be build with 2mm (1/32") hollow carbon tubes.
  • Straight joints are to be reinforced with 1mm carbon.
  • Bent joints are to be reinforced with 1mm pianowire.
  • Hollow square carbon (also 2mm) will be used for window- and doorframes.
  • Full functional door on starboard to get the lipo's in and out.
  • Double 1mm Single 1.2mm ply for the base plate relative to which everything will be placed.
  • Double 1mm Single 1.2mm ply for the wing roots.
  • Double 1mm Single 1.2mm ply for the firewall.
  • Very thin veneer strips around 2mm carbon for the horzontal and vertical stabs, which will be 2mm thinů
  • Full functional landing gear, the same construction as in the previous build Super Cub.

Characteristics, wings:
  • As light as possible.
  • Flaps anyway.
  • Two wing halves instead of one full wing.
  • Don't know the rest yet

Setup:
  • That totally depends on the final overall weight, but probably a Hacker A20-50S, spinning an APC-E 8x4, draining from a ThunderPower 3s1p 1350 mAh lipo.

To be continued...
