RE: Choose the right EDF system
6600Kv?????? and 68mm fans.... that will draw a huge number of amps, and I can't imagine being able to run more than 2s (3s and 6600Kv means your no-load motor rpm will be well over 70,000rpm... there are few motors which can survive that). I'd imagine that motors of ~3200Kv would be a lot better.
