Rio EP Brushless Setup

[Brushless55]

I don't think the 35mm prop will have enough bite on this hull
36mm would be the very smallest I would go, a 38mm could get some great speeds but a 40mm I think would be better

Thanks for the input guys. Where can I find a 38mm and 40mm prop that fits a 1/8" shaft? The 35 was the only 3 blade I found to fit a 1/8 shaft.

I actually had to go to a fairly small diameter prop. I'm running the 1440 Octura plastic prop and my torque roll went away, and i get halfway decent speed with a 2s lipo. I'm running a Tekin RS speedo with a Novak 10.5 motor until my 36-56 motor and 60A speedo come.

the 10.5 motor is a 4200Kv motor, and the one i have coming is a 2600Kv, but i plan on running 2 2s lips with that.

you can make a shim out of brass tubing.

have you checked your trim tabs? maybe try taking them off completely and see how she rides.

Here at OSE,click "Home" up in the links.Thats gonna take you to OSE store.Then look for "tips",click and go there.You`ll find there how to make 3/16" shafts prop fit 1/8" shafts using home made bushings like Jesse is suggesting.Very easy to follow instructions and you save money as its easier and cheaper to get props in 3/16 than 1/8.This way you can use them in bigger and smaller boats!!,...hope this helps,...Al

That could be a great prop! I'd like to try one.

you would have to space it down to fit the 1/8 inch shaft.

i've got a spacer ready. i think im going to try it.

Let me know how it works out!

well i ran this in my rio with a cc sidewinder w/ the stock motor on 2s and i think it gained maybe 3mph, it seemed like it was faster anyways. and got rid of some of the torque twist.

also i dont know if its because i cut the scoop out on top of the canopy or because of the prop change but everything was maybe a little warmer than ambient temps outside. and before stuff was getting HOT!

overall i like the prop and would recommend it as an upgrade.
i will get plenty of test time this week since ill be at garner st. park.
after i get back ill try brushless again.
