My DIY Quadcopter

Fly today but stay learn for setting KK board..it fly in stable mode but certain setting must be doing..Study and learn from my friend..

FC KK2.1.5 firmware 1.17 pro.. Firmware is stable and suitable for video recording or photo..

FC KK1.1.5HC with firmware 1.6++..firmware can select 5 mode SL Normal, Acro, SL Mixing and Alarm..

Step to change mode 2 to mode 1 futaba 6EXHP

Step to change mode 2 to mode 1 KDS radio

Step to change mode 2 to 1 Futaba 8j or futaba 9ch
