Freewing Avanti, Technical question, any help is appreciated.
Hi friends,
Im planning to buy freewing Avanti S from motion RC.
The older version came with 1850kv and 12 blade fan... and made an amazing whoosh sound... and thats what got me interested.
Now I want to buy one and they have the new version which comes with 1920kv and 9 blade fan.
and their youtube video says: With the new version what you lose in sound you will gain in power.
OK... I was more into the sound than the power.
Question:
What happens if I buy a 12 blade replacement fan blade and just switch it my self...
so it will be a 1920kv motor with 12 blade instead of 9.
it has a 100A ESC.
if I do this Will it damage the ESC?
What will I lose and what will I gain?
Thanks a lot.
Ben

Mount the new blade on your fan ad a bit of locktite ( blue) on the fan nuts
Use a Clamp meter and check amperage ( around the black or red wire at the battery connection) with a fresh charge battery(6S) ..any imbalance stop and rebalance the blade or spinner , this can be annoying ..if well balance go full power and if its more than 100Amps you need a new ESC ..120amps maybe or HV ...maybe better to test the fan on a test stand .. in the model if the blades broke its ugly
sorry for my english hopefully this help

Make sure the clamp meter can handle DC, not just AC.

BTW, to get the true current, put the clamp over the "red" not the black wire!
I have actually done interesting combo recently, chopping off 3 blades from the 90mm, 12 blader fan, it was too amp thirsty, it sounds just as good with a
9 blade 90mm powered "Thunderbird", with rotor reduced from 12 blader.
dramatic current reduction running only on 4S
