    Howard, to avoid confusion those are Prather propellers, not Panthers. Don't want someone to search in vain for Panther props. They are currently being supplied to the industry by Hyperformance Products.

    The Prathers are very 'similar' to the Octura "X" series props, and Octura was not happy being copied. But they are not actually identical, having different pitch ratios - most around 1.5:1. I use both brands, the 230 and 235 are particularly useful on many 4S race boats. Their stainless construction makes them harder to work but they are less prone to bending in use. Many Octura props need to be hardened to prevent bending in use, especially if they are thinned too much.

    GPS speeds are very accurate in real time, but unless you can get an average speed over a fixed distance from the GPS unit you'll always get a slight discrepancy between it and time traps.
    I made 4 run with a panther 235 but the boat bounced so bad i couldn't get pass 75. I put a panther 230 on and run 90.5mph after 4 run with a bigger prop. I'm sure i can go over 330' and stay at 90. Later i will show you how i set prop angle, i just need to take some pics.

    Funny we used to get slower readings on the GPS when we ran NiMh we would go faster with out the weight of the GPS.

    Howard's cat would be legal in a NAMBA SAW event, running in T Hydro or T Offshore classes. But getting 90 mph on a GPS and running two back-to-back passes for 330 feet each are two far different things. I'd like to see Howard try it - and succeed!

    BTW, for those who discount GPS accuracy, consider this. I usually run a Garmin 101 in my SAW boats through the traps. The GPS speeds are almost always within 1-2 mph or less of the official timed speeds - this at 80-90 mph. What GPS inaccuracy? I believe what I see, not what someone else reads online.

    This info came form Mark Grim when I was unable to get over 68 with my Striker 41with a 2230 1Y on 10S2P and hurt 1/2 of my packs.

    I like threads like this, because so many people spout off their gospel about what you can and cant do, without any logical info to back it up (usually just because its what they heard). Those people tend to jump ship after the thread continues, because they will be exposed if they stay. There has been a lot of good info in this thread, and it usually turn out that way when someone decides to push limits and does so with some integrity.
    This thread started out a little rough because I think alot of us didnt know what to expect when howard seemingly ignored our posts, but in retrospect I think he did at first because he was expecting some negative banter.
    When I first came to this site I took lots of crap for saying I GPSed my supervee in the 60's. Now I have put many boats well beyond that, and nobody really cares or questions about an old supervee.

    Howard:

    Are you finding that you have to trim the boat to steer left at low speeds in order to go straight at heavy throttle?
    My 32 turns slightly right at low speeds but when i throttle it go's straight. Only in that vid with the genesis was the steering off, it always drivers straight. I will never set my steering trim in the water, i set it with the tunnels. When you are looking for top speed everything needs to be straight with each other. If you run a single motor and your boat is pulling you might want to check for some play in the steering rod or the rudder is to long. I started this thread to show that you could build a boat to run in the 90s and spend less then 900.00. All my parts are cheap but the esc, its not the best but it works great. I don't have any problem with thing getting hot, i check that run with the genesis and motor was 130 and esc was 114. When building a boat (slow or fast) the cog and prop angle need to match, I like to start with prop angle and work from there. This is why i like a strut, its easy to change the angle. Lets all just work together and we can build some of the best boats out there.

    Hey Howard do you know how many amps you are pulling on either boat?
    And congrats on making 90!

    I think you should consider the x648 that was suggested earlier...............

    I took my genesis out for a run but found a weak steering rod from my last flip. I have a vid of this run. http://www.youtube.com/watch?v=

Tell him what you need and he can help you get there without a lot of trial and error - and without buying a lot of props you don't need.

    Thanks for the info I will see how this prop works. I'm sure i will need help with a experienced prop builder.
