i have a Phil Thomas super sport 45 it s has never been run,i want to run it on 6s , the motor i have for it is a neu 1527 1y , 1250kv , the guys in my club run leopard 4082 1600kv motors on 6s for q hydro class , my question is , will i be able to keep up with them , will my boat be fast enough , if not, what motor would you guys recommend and with what prop .
I don't race but mine goes pretty well on that setup using 6 sup swinging a 52mm prop.

with your lower kv motor you can swing a larger prop so speeds will be equal to the guys that run higher kv motors with smaller props.
You will have the power, but it is a big ask for a sport hydro to keep with riggers in the hydro class.
think he is talking Q class sport hydro not rigger hydro.Quote:

I ran mine w only 6000mah because of space restriction in my hull, but I would recommend at least 8000mah
I am setting up a new 6s sport hydro with T.P. 4060-1240 kv motor, both the prather 240 x 2 or the octura 455 seem to work well . I think the larger 457 moded prop might be too much for us running a single 6s pack [ not 6s2p ] sounds good though madmikepags.
I have ran up to a 452 prop on my PT 45 with 6s2p 8800mah and I would say for my setup that is about as hot as I would want to run it and still have good runtime. I am using a Neu 1527 1Y 1250kv motor in mine.
thanks guys , i will run two 5000 mah 6s , with an octura 450 and test run it with bigger props for 1 lap ,to see where the temps go
a club mate is running a prather 240 which has more pitch and diameter than the 455 octura and his set up with a 1250 motor and single 6s pack runs cool for 6 race laps. its definetly the go to start off small and work your way up in sizes.
I too, ran a Prather s240 on 6s with that motor. A 447/3 also works well.
Again, as rol243 stated, these are on 1P setups only for racing here in Australia.
That is a tried and true set up. 1527, 452, (2) 5000mah 6S's. I ran the castle 240.
Hey madmikepags, what esc or amp range would you recommend for the above setup? How long a runtime with 6000 mah? With the 457 2 blade? Thanks
at least a 200 amp speedo, my runtime is a race time between a minute 10 and a minute 30. This is a RACE setup not a sport running setup.
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
It does work. lower kv equals more prop and pitch as opposed to higher kv,s that require smaller props .
never said it didn'tQuote:

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 :wink:
as opposed to my picture (upper left)running high KV that got me 1st :cool2:
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.
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.Quote:

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