Updated Motor

[STRlKER]

Hey all, I m currently building an old Midwest kit, the Electric Hots and I’m looking for some guidance in determining what “modern day” motor, esc, battery combo would be a good fit.
I have included a couple photos showing the old recommended size, as well as specs on the aircraft itself (weight, wingspan, etc).
Help with determining what I could use, as well as where to purchase would be greatly appreciated
Thanks

Based on the weight and original (Cobalt 05) I would use Eflite Power 10 KV 1300 and 45 amp ESC with 9-6 prop to start. 3S for mild, 4S for Wild (check amps!). Up the prop based on amps, the Opterra has a 11/6 on that same motor.
