This is my ATLAS 4 from FlyfishRC, nothing special with this one, just the pleasure of sharing my build here.
I use this quad for mid range, crusing and chasing my friend's aircrafts and doing some tricks around the trees.
I am using DIY MOLICEL P30B 3000mah 4s with this craft, stock 1804 3500Kv motors are powerful and even if the quad is so heavier than a li-po version, I really enjoy to fly this thing!
Be careful with the Li-ion packs, I scaled the throttle curve to 80% to avoid exceeding the maximum cell current of 36A.
Flight time is about 12 minutes if I do some nervous flight and I can reach 23 minutes or a bit more when I slowly cruise at low height.

My 4s 18650 3000mah battery weight 195 grams.
The quad without battery is 195 grams too!

The Goku GPS is a beast, lightweight and get a GPS fix in a minute during a cold start in a new spot without ground assistance.
