Started building on 17th of November

- Started with horizontal stabs and changed to another solution for guiding the servo cable outside the stab: drilled a hole of 5mm to inner rib and herex strut to pass cable to front of stab and get it out through the front hole of the rib. For this I took out the pins from the servo plug, fixed it to a string and run the string with servo cable throuhg the holes into the front chamber of the stab, then reinserted the pins in the plastic plug cover.

 - Finished stabs, started with wings, servo installation and gear installation(25.11)

 - Finished wings, front gear installation, RC board, started rear part of fuselage, finished tank & hopper(20.12)

 - Working on thrust tube, rear servo cabling, canopy(03.01)

- Added some white check design below on tip of wings and elevator

- Everything installed and ready, some smaller settings to do(14.05)
