they have been in the loft for a while and i would like to refresh them with brushless.
one is the MFA piranha, seems a good place to start as it is the 540 motor size and lots about, just need to work out what power to go for.
the other 2 are going to be a tad harder for me to get my head around, they have the bigger 850 torpedo motors in and how that would work
with brushless is over my head. they are the MFA Spearfish and MFA Seahawk.
How do i choose a brushless motor, back in the day i chose the motor turns and for me it was around a 10 turn, matched up the speed controller
and chose what Mah pack to use and that was it.
thank you for any help
