Hi,
My plane (a cheap electric glider) uses a 380 brushed motor. What would be an equivalent in brushless? I would like to replace it not specially for more power but because I need a new ESC in any case and it doesn't seem that sensible to put more cash into old technology. The existing motor turns a 6x3 folding prop and runs off a 9.6v NiMH pack. The plane's flying weight is around 650g.
I'm hoping that a "380 motor" is pretty standard, and someone can tell me what that would mean in terms of Kv, amp and watt ratings that brushless motors use. With that info I can see what looks suitable from my favourite budget supplier (Giant Cod).
Originally I hoped I could retain the existing prop, but I guess the shaft size is unlikely to match so I might have to replace the hub anyway. Even if that's the case, the plane really suits a small prop for low drag when folded and to minimise chances of damage on landing, so I guess that means a high-speed motor.
Thanks in advance, Tony S
