carbon filled props

[drdarren]

has anyone tried the carbon filled props they sell at offshore electrics. are they better than the plastic ones.how do they compare to the metal ones. i want new props but i dont want to deal with balancing or sharpening

I have tried the Graupner series for 3/16 shafts and they are very very good. They have similar or even better performance with the octura 1.4 series. I am very happy with them and very good speed.

the Graupner CF prop are quiet good for the money, better than cheap plastic, but if you want to improve speed and efficiency, metal prop are the way to go!

I love this story, I won 2nd at the 2005 electric nationals with a graupner prop in p-mono! Out of 3 heats, I had two firsts and a second. Alan Nayman had 3 first place heats to win the class. Not bad for a feigao motor and a $5 prop. I do have to give credit to Alan, he helped me settle the boat down with a pair of tabs.

Good one Steven! Feigao and CF prop is a really good start!

looking at the site, there are various graupner props to choose from. which do you think is the best for the traxxas villain ex.

[Steven Vaccaro]

We found that the graupner 2317.51 and 2317.51L props had to be cut down to 48mm to work. But that was tested before Lipo power. With lipo cells things have changed.

i am really looking to keep things simple so i dont want to shave, smooth, balance or anything else. I like to keep it easy. Is there much of a performance difference between the different models

Thanks

The stock 51mm props would overheat the motors.

i am looking at the website for the props and it says they are for shafts with drive dogs. what are drive dogs?

[DISAR]

Drive dogs are located on the shaft and fixed in place with an allen screw. Then the propeller slides on the shaft and into the drive dog, then the propeller nut comes behind the propeller and secures it in place. This is a drive dog

There are two main types of propellers, the ones for drive dog and the ones that are screwed on the shaft. And then there are various shaft diameters 1/8, 3/16, 1/4, 4mm.
I guess that you started getting into boats. I would suggest that you read some boat manual (I started with a Kyosho bluestreak,I think) to get used to the terminology of the various parts.

The explanation is much appreciated. You are correct , i am new to this sport. Currently i have rc cars and helis but i am interested in boats. I just got the traxxas villain ex and want to maximize its performance. I added the engine cooling kit. I am getting an auto bailer and i wanted to improve my props. I already have the prop shafts and looking at the package it does say it has the drive dog on it.

You are very welcome to the boats world and in this site you can find tons of information. Learning is continuous and never stops. I am really sorry but I do not have the Vilain therefore I cannot provide any info specifically for this boat. Maybe somebody who has it can comment or if you get no success start a new thread with the Vilain in the title. Good luck!

Darren, I am very familiar with the Villian EX, our club, here in Fl, has been having a great time with them for the past 7 years. Many of us have tried to hop them up and found it possible but the expense to gain 2 or 4 mph was not worth it. We have since gone back to all stock and just enjoy racing them. Here is a set up I used at one time. Counter rotating Octura X447 props and shafts from OSE at a cost today of $95 and I put in a pair of Trinity Monster Max 19 turn brushed motors and 13 tooth pinion gears. This set up took the boat from 23 mph to 27 mph. All in All the investment was just over $200. It was an interesting experience but not worth the money. The Villian is a great boat but was never designed to be really fast boat but they are a ball to race and they are almost indistructable and well suited for a small to medium pond. As I said our club is still racing them once a week.
