As flying starts to be more fun i started to destroy more and more motors (burned coil or damaged motor wheel)
as first I bought (till now) 2 package of original 7020 replacement motors. The price was around 3.5$
As not only motor but also gearing starts to destroy, I take also set of original motors with motor housing and gears.
Because also motor housing and big gears was worn-out after time and as it starts to be annoying to replace motors every week, I did try to use bigger motors to extend the lifetime (and little bit shorten on flight time).
Original one was 7 mm diameter and new ones are 8.5
As bigger motor did not fit into housing so modification is necessary. Here you can find “how to” video (this is my first guide on Youtube):
I also replaced 2-blade propellers with 3 blade – there’s even no change during controlling – so that update is juts “nice to have”

Hopefully this guide will help you 🙂
