I have a neu 1105 2.5y and i am using a 4.1x4.1 on a 2 cell and its moving right about 90-100mph i was wondering if i use a 3 cell should i go smaller or can i use the same prop???

also the site say i can go 15v is a 4 cell suitable??? i was told 170-180mph

any help is always appreciated

The motor can definitely handle the 4S. Now, it depends on your ESC. Going to 3S or 4S with the same prop will pull more amps.

i was thinking of running the same prop on 3 and 4 cell since the prop is small
i dont want to go bigger than a 4.1x4.1 because the kv is 3800. i think a 5x5 would be too much prop for the 3 and obvious 4 cell but on the 2 cell would it be ok???

The Castle 45 should handle the 4.1 x 4.1 on 3 cell. Check the voltage with a watt meter if you have one. If you don't have one, borrow one. It's the only way to measure what she's pullin'.

I ran a Mega 16/15/2.5 (edf) 3800kv with same prop on 3 cell on a pusher jet and it pulled about 38 amps WOT.

On 4 cell, this same setup will pull 60 - 80 amps, way too much for the cc45
