Simple design, max fun after tuning to suit.
3D printed body
10mm square carbon arms with timber dowel inserts. (scrap)
KK2.1.5 mini with RC911 FW (KK2.1 V1.6++ AiO R5) ( $6)
Turnigy Aerodrive 2822/14 1450kv (x3= $25.50)
Afro Race Spec Mini 20A w/BEC ESC (x3 = $30)
Dalprop T5045 triples ( $ 3.50)
Turnigy TGY-9018MG servo ( $9 )
Rotor Bit mounts. ( $ 16 )

Without factoring the frame and arms (my first unit was made from 3 ply and 10mm pine flew beautifully but was not crash resistant) the cost for this is under $100.
That is a lot of cheap fun.

RC911's FW is brilliant, I changed stick scaling from 30 to 50 and Self Level from 50 to 80 no other changes to tuning. A bit more SS to be done to get rid of the slack and she will be ready for ACRO.
