prop question

[sanyijr]

Hey Camero-junkie,

You say its a 150 amp esc. Did you buy new? Used? I am not convinced its a 150. Looks small to me compared to the caps. Looks more like a 90.... or even a 60!

(And if that is the case.... I am surprised it hasn't blown)....

In either case, I think its your esc. Either under rated or faulty.

I am having the same exact problem with my new genesis. 4s 4000mah 30c lipo's, hobbywing seaking 120 A ESC, stock everything (prop,motor, 4mm flex shaft) also new to boats. I have timing set high. I get 5 minutes and it cuts
power way down, motor and lipo's arent even warm esc is hot. i figured it was a bad esc? now I dont know what to think? have ordered turnigy 180A esc

[camarohrod]

do yall think this could be a motor problem? i ordered a new swordfish 200a esc and new 45c lipos to see if thats the problem.

I think the ESC's are too small.That is a good size hull and cats take more to get out of the water.Once up on plane all is good.I run a 180 on my Geico and it needs all of it.Mind you I've got a hot setup.

and I do not think timing should be high. If anything, I think these are 2 pole.... So low timing is in order.

Hey, did you ever figure it out? sounds like the same exact problem with my genesis when I first got it 3 weeks ago. I had a hobbywing seaking 120A esc. did same as yours everytime. I simply replaced it with the T180A, problem solved
what I can't figure out is I'm running 2 x 2S 30 to 40 C 4000 Mah in series and getting 5 to 6 minute runs. but if I went with your setup 2 x 4S 4000 mah parallel (8000Mah) I thought it would give me 10 to 12 minute runs.
you say your only getting 5 minutes? don't know if that's the 20C part or not.

well i bought a 647, 440/3 and i tried both of them and i cant seem to get any more speed, i think my motor is just crap so i just ordered a leopard.

[CatMan]

thanks,
I've been thinking about trying the 440/3 prop myself. which leopard did you get? I've been looking at the 4074 and 4082. but don't know enough yet to know which one would be better for me?
just want it a little faster, but looking for setup that will also give me longer run times. I've decided to switch to 1 piece flex shaft before I switch motors, so I still have time to figure it out.( I hope) and probably go from 2x 2S in series to 2x 4S in parallel to achieve the longer run times. wondering how long before my stock motor craps out? but more afraid of flex shaft breaking and putting hole in hull.
