Hey guys I want to get a sensuous of opinions on the subject of prop modifications. I am thinking of doing a thread pertaining to modifying props, balancing, polishing, cupping, pitching, ect,,, I know this is a pretty stickey area in discussions as a lot of people that have poured hours into tweaking their props want to keep the edge over competitors by not sharing what they have done. I'm not asking for others to share but my intentions are to elevate this sport into the 150mph arena. I'm not going to do that but I would like to see several others to. And in my opinion this sport is growing and hopefully manufactuers will be developing new and more advanced products for us to use. Not giving any secrets away as it only takes a few clicks and anyone can find out how to improve stock components. The art is in knowing how to use them. And maybe this will be just the push some need to get to the next level. But I don't want anyone to be cooking components because they put too much stress on motors/ esc. As there isn't really much out there for moderate enthusiasts to learn from. And I would like to learn some myself from others opinions, experiences. What do you think? Good or bad thread? Open the can of worms or keep the lights off?

I'm shocked this thread has not had much attention or any responses yet. But I myself don't know much about cupping props or any of the so-called secret ways of making a boat go as fast as we want them to but I would sure love to learn guys so I mean I like to see some help on here. -

Sounding good so farComment

I for one appreciate any info on this subject. You can simply throw money at things and get so far,but... prop work IMO is "THE" trick to going further faster.I am basicly a sponge on this subject and should soon be dabbling with prop testing myself.I have been but am thinking of something more serious and factual.
Love the idea!!!Comment

In all honesty knowing is about 1/2 the battle, prop work is still a bit of an art form, you can tell someone how to paint fine art but only a few will be able to really paint priceless pieces. But I have also found that most people who have experience with the ins and outs with optimizing props for their boats do tend to be pretty tight lipped about the things they do to their props which is frustrating for new comers and is also a very large Achilles heel for the rc boat community because most people who want to get into it and do find that they can't compete with the fast guys because they don't entirely understand the characteristics and mechanics of props and for the sake of the sport and those who are wanting to become a part of it I say, if you have something to say then get on with it man lol. My 2 cents.Comment

I to would like to see a decent how to on props. I dabble a bit but would like to know more.
I like to detounge all my props. I used a couple of m series props a few years ago as a guide and then made a few templates out of coins.
So all I do know is put the coin on the prop (flat side on the hub, front edge of coin on the leading edge of the hub) trace the edge with a scribe and i know both sides are the same and the right shape.

Mmmm this would be really interesting. I agree that what would be good is if some of those that know could share some basics. Of course there are a few guys that make a living out of prop mods and it is fair enough that they should keep their 'trade secrets'. Prop mods for dummies, or those of us that are keen and handy enough to give it a go would be great, but I suspect though that all the theory will we can get will still need the trial and experience that only time brings. After all the greatest learning comes from making mistakes! I have a couple of props coming that I plan to work on, so I'm going to jump in, learn a bit and see if they can get me more speed. Hopefully I won't wreck a good prop in the process.NZMPBA 2013, 2016 Open Electric Champion. NZMPBA 2016 P Offshore Champion.

The link above is one that I found most helpful when I was tinkering with props for my mono, it helped me get 64.3 mph out of my 33" seaducer on 4s just from following the detonguing portion of X series octura props without even adding any cupping to the trailing edge yet.Comment

Yes that too is some good info that has been around for a while now.Comment

I don't have any numbers on how fast the boat was running before hand with an x447/3 blade that wasn't detongued but I can say that it was a dog, I could turn the boat around at full throttle in about a 4 ft radius and it would never try to spin out, the esc and caps were always HOT when it came back and just by dropping a blade and going to 50mm the boat will now blow off the water if I don't watch it any turning at WOT would be a bad idea!Comment
