Tech question: static vs flying amps

[Frank v B]

What is the (rough) ratio of amps drawn by a motor when measured static on the work bench versus unloaded in flight at speed??

If I am reading 25 amps static (wot), what would you expect it to be while in the air?

Need for speed, not smoke.

If it's a fairly clean design it will unload 10-15% depending on how hard its being loaded. If its loaded KV is %75 of unloaded kv could be as much as %20.

Thanks Ed.  I knew either you or Ben would have the answer.
