100 mph Zephyr, need input on motors from experience

[elliott000]

Hey guys, Ive been chatting on the other forums with a couple guys including chris on power systems for the Zxr im building, I have 6s 5000 sitting at home or I can go 8s. The zxr will be 70" width and weigh in around the 3.5 - 4 kg.

Question is motors. watts....

I would like to build this one up to do 100 mph flat n level hopefully with overhead for a bit more top end if i hammer the stick. Ive been doing ecal and such but am having trouble coming up with a setup on 11" or smaller prop that doesnt spit out a prop stall error, whats the "prop stall thrust" all about?

Anyone here have any ides or first hand experience on a setup with 40mm x something motor?

Cobra 41 30 530kv from innov8tive

This looks promising but when I goto prop data on an 11 x 8.5 it has thrust just slightly over a possible rtf weight and I want the ability to hand launch this pig

Any ideas are appreciated or if you could point me to any other forums that have usefull info Ill keep reading.

Thanks
Elliott
