Nice model and build video. Amazing how much power you get with an 8520 motor and 1S Lipo.
What is your local source to purchase the 8520 and 1S Lipo?
Congrats, well done and documented.
I'll buy lipo from here:https://www.electronicscomp.com/3.7v-300mah-lipo-rechargeable-battery-for-drone?search=lipo&page=4
For 8520 sometime i'll buy from amazon.in
Thanks.
