I did some changes and made another run.
I changed the 22 tooth pinion gear over to the 25 tooth mod 1.
Then changed the 40 tooth spur over to the 36 tooth spur.
The AXI 2826/10 motor still handles it fine. Top Speed is noticably greater. BUT........there's the "word" again.
Cogging is there but ONLY on startup. Any rolling speed at all and it's gone. The old 1/4 throttle blip does the trick to get it going.
Runtime is down.......came down from 25 minutes to about 20 minutes
Motor temps are up........probably 150-160 range.
Lipos are pretty warm........100 range
ESC is cold.
Ambient is 58 degrees outside today.
I think the better setup will be the 2826/8 with a 22 tooth pinion/40 tooth spur. We will soon find out.
