I know what you mean, just take your time and make one change at a time, this will help you to see the trees not the forest. Best of luck  :-))

Not sure if it's already been suggested but when I secure a brushed motor, I tend to run the motor from a single AA dry Duracell battery and find the "sweet spot".   There's not enough guts in a single dry AA to turn the motor if there are any problems with alignment or the shaft.  It's a knack, but pretty old skool tried and tested method over the decades.  Personally I wouldn't fit a fan on that motor, it's only like hiding it under a little bit of carpet and crossing fingers.


You can always take each motor out and check the resistance across the terminals with a multimeter at different shaft positions, same for running them on the bench or in situ with a multimeter or power meter to check the current but in my experi nce a bad motor feels different to turn or sounds gnarly when held on the bench anyway.  All that is quite common checks also.

Hi Chris,


Did my original suggestion of trying without BEC and fitting a separate RX supply work for the ESC glitches after all?  Curious as to what was the fix on the problem for the individual motor overheating though?


Glad it's sorted anyway,

Wowsers you have made huge strides on this build! I read of your issues with tight props and motors with interest as I bought a cruiser model with the motors and shafts installed, but one of the shafts seems to self tighten it's universal joint or loosen it depending on which way it revolves and wondered if the shaft was out of alignment or some other problem.


Keep up the good work and I am looking forward to loads of painting!
