Where is the best place to buy the Octura 1435?
I am trying to mod a penguin 660 and am hoping this is the prop that will work. I have found it at mjmod, but was hoping there was somewhere else I could buy it from. |

Octura props can be ordered from http://www.funrcboats.com/category.aspx?categoryID=109
$2.99 plus $8-9 shipping, i forget. or directly from Octura (they have no website nor email) they only take mailed in checks or add a$8 CoD and i think have $8 minimum shipping. Octura Models Inc (847) 674-7351 7351 Hamlin Ave Skokie, IL 60076 long as i have been following this thread i don't think anyone has posted a different place that has them. the best price is obviously to go the the hobby store. They are like $1.50 at mine. |

it brand new, and no dirt, also i think that red cap is for the centering rod, the shaft assembaly is what is sliding back and forth with the prop.it cause the entire assembaly to slide up the rod and makes baldes hit the stopper, also always spinning the worng way ... man this is so fustrating

I'm sure this has been asked before but with 1000 of post to look through . . . . .
What kind of flow can I expect from a modified MJ900? Would two work well in a 40 breeder or would I need a third? Thanks |

I have two in my 40g breeder and would not run two if it wasnt a fully stocked SPS tank. The 900 with the Octura 1435 is estimated at 1500gph. Frezel If it is spinning in the wrong direction constantly that is usually a sign that the prop is too big for the motor or there is to much drag. Try to make sure everything is centered and if it is, then try cutting the prop down slightly and it should correct itself. I have had to do this a couple of times on some of mine |

How much of a gap should I have between the prop and the stopper when not running?

Do any of you get it to be as quiet as it was originally?
I've been trying to get it quiet/silent but I haven't yet managed to get it to a tolerable sound level. I'm using the Octura 1435 on a MJ900. Wondering if it's just not something I will be able to achieve.

There are several different types of noise from this mod. 1. magnet out of alignment and rubbing inside the motor housing Does it quiet down without the shroud on? 2. propeller hitting the stopper creating a racket Is the propeller constantly hitting the stopper? 3. humming from the propeller spinning Is your propeller mounted backwards? Is it on straight? 4. vibration causing the pump to bump against the tank glass How are you mounting the pump? Which of the above are you trying to resolve? D. |

1. I can't seem to get it to run without the shroud on. It either does nothing or spins backwards, ejecting the magnet and propeller.
2. Don't think so. I took the stopper out and it still makes noise. 3. The notches in the 1435 are towards the MJ, if that makes sense. I think it's on the right direction. 4. Suction cups, don't think it's hitting the glass. I'm guessing from your response that people do, indeed, get it to run silently. So I'll keep trying. I'll try some more without the shroud. Thanks

Mine are quiet. I have to put my ear to the glass to hear them...quieter than a standard MJ.

Yes they can be made to run silent or as close to the stock MJ at any rate. How is yours noisy? Did you make your own shroud and cross brace or built from a kit from mjmods.com? Also what are you using for the rod? Stainless steel or carbon fiber? Are you also using the rigid tube as well with these? is there a lot of play inside the rigid tube and the rod? D. |
