This pnp quadcopter is one of my 2 inch freestyle builds it's built on a usmile Fi-100 frame ,I used the Speedybee f405 aio combined with 4 of the hglrc 1303 5500kv motors and a 5 to 9 volt bec so you can fly this 3s or 4s,I also installed a happymodel EP1 TCXO elrs reciever , just install your own dji 04 lite and you are ready to go I recommend 450mah 4s batteries for about 4 to 5 minutes cruising or about 3 and a half minutes freestyle flying . These are fantastic little drones fast agile and quiet ,ready to fly weight with a ovonic 450mah battery is 155 grams . It comes with a little dipole antenna but I recommend using a dji 04 pro antenna for maximum range.
