8XL with stock ESC

[ReddyWatts]

Right, the largest prop to use safely for an 8XL with a 45 amp SV controller is a X432 prop and for a 9XL its a X435. These props are not big enough for the SV hull. Needs a bigger controller for these 2-pole motors.

so if I put a 9xl on a x440 im going to pull major amps and blow the speedo

[ReddyWatts]

It will be around 75 amps on 4s and under 40mph.

[kck741]

pointless

[ozboater]

my set up runs sweet with the 9xl stock esc and an x440...

[ReddyWatts]

I have heard of people using 6s with BEC on the blackjack esc and now you are using 75 amps on the SV esc? Is anyone else doing this or is it going to fry?

[ozboater]

doby runs the same... he gave me the idea... he s been running his SV that way for a couple of years i believe...

[ReddyWatts]

What kind of speed are you seeing with this setup and why did you change from the SV motor?

[ozboater]

why - because i can

as for speed differences, i d say 5mph max... def'n increase in torque... you have to be a little less trigger happy with the throttle or she ll just prop stand and flip...

[kck741]

what are your temps

[ozboater]

i don t use a gun but they are not bad at all... i d say 120 tops for the batts... they get the hottest... the esc barely warms up..
