Recomend me a motor?
I am working on a scratch build Airtronics Q-tee. It was my first RC airplane in about 1976. It used a Cox 049. I would like to buy a motor form Hobby King or similar that would turn a 6x3 prop at about 15k. That would be about 10 amps? I would be running 3S lipos. So about 1500KV?

I would guess around 13 Amps.

If you motor sucks 16A it must be far higher than 1600Kv, and thus spinning that 6x4 prop at far higher rpm........ or hopelessly inefficient.
Look what an ancient Len'sRC 20mm/17T (~1550Kv) can motor could do with a 6x3 GWS HD:
6x3 GWS HD....... 13740rpm, from just 4.6A/50W!
