Very true. I've seen a lot of props on RTR boats that were very out of balance and would be scared to use them. I worked on one RTR gas boat prop for a member here and spent over an hour getting it balanced it was that far off.

I found a nice website which is for full-sized boats, but has lots of short, basic articles of props which help shed the light on a lot of terminology, what rake is all about, cupping, ect.

Very helpfull for people that want to try and do some shaping to help tune their prop to their own boat setup. The ultimate last step on getting the most speed out of your boats power and definetly for experimenters.

Just follow the guide on the left of the page and it walks you through all the major aspects. [8D]

Cool, as I'm am new to all of this this post definitely helps. While I don't think I'm ready to do it all myself yet I am going to look into having someone do this for me.

Hey, do you mind fixing the first link? would be greatly appreciated!

My Feedback: (1)

We can't fix the first link as after a certain amount of time we can't edit them and for as old as this thread is, we're way beyond that date. Here is an updated one though: http://www.offshoreelectrics.com/pro...od=dh-topq5700 . Steve redid his site a while back so I think that's why it isn't current.

Nice yes, but pricy. He sold a lot of those on eBay. I'll stick with my Top Flite as, well, I'm cheap!

This is a very nice balancer but they are out of stock till mid May.

very useful website.

asupervee72

does anyone have a video of a prop that is balanced and shown on a balancer? preferably something that will demonstrate what a 3 bladed prop should do as far as being able to stop it and it staying there, a video would really help

Try this site, it might be worth downloading: http://whobbies.com/fullthrottle1.htm

Ron,
That was helpful! I think my only concern is that he didn't mention top to bottom balancing only tip to tip.

ron...i found the whh link very helpful...i prefer vidio to the writen word..and that vidio made me feel confident i can balance and sharpen my own props ..keeping in mind i am a pleasure boater so the dont have to be race perfect props...i have found the whole link very informative...if you write a book make it on setting up gas boats..that would help a lot....bob

Prop balancing and sharpening is only scary the first time, after that it's a piece of cake. I compare it to drilling the first hole in a new hull. Speaking of props, I've got 4 in the shop needing some work done on them real soon.
If you want a book, I'm not the one to write it but there is one on the market that I've recommended for years to any RC boater, Advanced RC Boating by John Finch. It's not that his other books aren't good as they are but this one is a must-have. It should still be available from www.rcstore.com .
Being relatively new to gas boats coming pu through nitro and very little electric experience it's a whole new ballgame in a way.

hey ron thanks for the repl...i have that book by finch..i think its more nitro than gas...still very informative..but i think we need a gas book ..ther is one called the gas boat book..by ron eyrlich..i have never read it..but as the hobby changes so quick..it might be a bit oldl...i have one of doug's with a weedy and just got the plans for the new boat...look foward to the building....bob

Sorry, I never heard of that one. John's books seem to be timeless as others I've got get outdated quickly in this ever-changing world of gas, nitro and electric boating.
Do you mean Rick Eyrich?
That's Rick, second from the left. I'm the first one on the left.

Found this site for buying polishing stones, good selection.

Good job, mcss383. I checked it out and there's not only a good selection, there's excellent tutorials how to choose and use the right stone.

The hardness of the stone is just as important as the grit. If you start with a hard stone they load up and only skip across the surface no matter what grit size it is. I suggest soft stones until you get to around 400 or 600 grit where I would change to a medium hardness so a point can be sharpened and maintained to help get in to the blade to hub corners.

I've tried a few lubricants on the bronze with the stones I have and it seems just plain old mineral oil (baby oil) works the best over any of the automotive type oils that I've tried.

I was wondering if anyone has a link to a place where I can buy a prop for my 1/ 8 scale Pro Boat Miss Elam that is ready to bolt on. I don't think I have the talent to balance and polish a prop, but I can put out a mean fire.[sm=lol.gif]

There are a lot of good prop guys out there. One of the good ones for gas boats right now is Chris at www.dasboata.com . Tell him what you want to bolt it on to and he-ll fix you up with what should work.

Not really unique. Here's another one:

It looks like it comes with more shaft sizes.

I found another article on props at http://www.abcprops.com/proppdf/PropellerCup.pdf . If you know more than basic math then you should be able to get more out of the article.
I did find myself giggling internally when I saw the name of the second author in the article, Dudley Dawson, which happened to be the name of Booger in Revenge of the Nerds!

So... Who can you send them to to polish and sharpen them??? And balance?? any suggestions
