My really hot prop is a prather 250 cut down to 56mm and cupped. VERY HOT PROP!!!

Very well. Thanks much for the input, madmike

Looking forward to this one, I've never thought of running a lower KV like this for Q

[rol243]

It does work. lower kv equals more prop and pitch as opposed to higher kv,s that require smaller props .

never said it didn't
lower KV takes a bigger wheel

I'm setting my P Hydro up with a much lover kv than I thought I would ever race with running a very big prop with help from Darin
as opposed to my picture (upper left)running high KV that got me 1st

I’ve been running mine with 1527 1y (1250kv) with a x452. Temps are around 110 after a mill. I was using single 6s 5000mah 60/120c. Started ever so slightly puffing cells. Went to graphene 6000mah and I’m good. Trying x455 this weekend. With the 5000 mah I was right at 65 mph. Dropped the strut a little and put 6000 mah in and was just over 70mph 3-6” of chop, it was hard to hold on to. 5328 watts on that run. Gonna try x455 and x648 this weekend. Maybe parallel 2 5000mah and see if it picks up more from less voltage drop.

the 648 might be abit small as opposed to the 455.

[ETOWNE]

I’ll start with 648 then 652. Not trying to cook it

I am also setting up a new 6s sport hydro with a 1250 kv motor, props to test will go from x450 / x452 / x455. a club mate has the same set up and he runs a prather 245, all is cool after a race .

Ya, that’s what I did. Started with x448. It ran hotter than 450. Think over revving maybe sending voltage back to speed control. I’ve read that Prather 245 is good but I have 0 experience with them so, I stay with octura. The x452 works good and isn’t cooking stuff. Sharpened and balanced is all I did to it.

[rol243]

you might end up using the x455 like me.

You’re pry right. I keep putting more weight on front. You running front wing?
