Ok so I got a sweet 160in C130 that I think will be around 55-60 pounds
I wanted semi scale blades so I made my own 16x12x4 blade props.

Useing a huge SK 6374 192kv motor with Castle 60amp HV ESC

I originally used a cheap esc and thought 8s would be ideal but now I have the Castle I'm getting real rpm numbers vs what I thought

So I know C130 is no speed demon, but I got 8 estate rocks on the rear for sweet takeoff and I got short runway

So at 8s 25c 5000 I'm pulling 40amps at 1200watts and 5325rpm 8.8 pounds of thrust and 60mph flying speed. Which is a little low

So at 9s 25c 5000 I'm pulling 50amps at 1700 watts and 5867 rpm 10.7 pounds and 66 mph

So at 10s 25c 5000 I'm pulling 56amps 1965 watts and 6174rpm 11.78 pounds a 70mph 1/2 stick is 22 amps and 52 mph.

At 10s I'm at 10 pounds of lipos vs 8s 8 pounds of lipos on a huge 160in wing span c160

All thrust and MPH is with calculator

So with this and knowing 4 separate motors are way more efficient than one big motor at the same amount of the thrust

what would you do?
