Navigator and U7 what's the difference?

[anaka]

Hi people
in the last months a bunch of new hardware is arrived to us and it is even harder to make a choice in some cases

in particular i'd like to know the difference between T-Motor U7 and T-Motor Navigator

they have similar price, similar caracteristics

it looks like U7 are a bit more heavy and pricey and basically i'm wandering if they are the best choice
i'm going to biuld a system based on MKBL 3.0

thanks to anyone that will give me a bit of feedbacks

I made my choice for the T-Motor MN4120-9's for my hex build. I looked at both figures like you posted here and came up with just a few small differences in specs and price. I have found the MN4120-9's for $119.90 US each. The thrust in grams are @370g more for the 4120's with the same prop @100%. The only other choice I have considered is the KDE line of motors but the cost goes way up. Crazy specs on lift capabilities!

the u7 have a massive bearing, bigger fan and more mass on the barrel but need certain esc's and the combo runs kinda hot. Navigators other than being a high pole count are alot lighter overall. Weird cause there a 12/14 pole but kinda pancake and swing a pretty big prop. They got good power but i have more confidence in my older mt and mn series motors still.

if mkbl 3.0 can't use t-motor 80 amp esc's skip u7.

hi guys let's keep discussing abouth KDE and Navigator...
I chose these two models just becouse they look very close each other

analyzing the 16"propellers field KDE looks to be a bit under the Navigator in therms of lifting

have to say also that the KDE weights 50grams less in total that it is very interesting
and it costs just some dollars less than Navigator as well...

if we move on the U7 and KDE 5215 things change a bit

and the main question is:

U7 wants a A80 ESC to work properly....does the KDA5215 works well with the MKBL 3.0?!?
