    I have my strut up all the way, 7/8" from the hull. If you look back a page or two I posted a pic . I would like to see some pic's of your boat if possible.
    Do you have an air dam installed? That might help to stabilize the boat.

    It's all a work in progress.

    Thanks. I wanted to get some testing in today but when I relocated the motor wires I noticed a solder joint was coming loose so out the window with the test run. Oh well, next time.

    On another topic, I've decided to make a stronger and wider turn fin mount. I'm almost done measuring and drawing it out .
    I'll post up some pic's soon.

    Here are a few pics of my idea to make a stronger turn fin mount with out having to get into the hull.

    I'll cut the rough shape with a band saw then clean it up on a belt sander. I might even polish it up on my buffer to a mirror finish.
    I'll start this project asap.

    Is the stock turn fin mount not working or something?

    I use a black ul1 fin on my elam and it's been great.

    I could wrong, but I think you might have it layed out backwards.

    Are you still using the stock connectors on the motor and esc and deans on the cells ?

    It would help the setup run better if you put 5.5 bullets on everything.

    Hey.
    Is't it the inside of the hull of the sponson the weak points for the stock turn fin and mount ?
    And I know most members love the stock turn fin to use on high end Hydro's for racing.

    It's not broken or anything, it's flimsy to me. I figured if I spread the load out it would make it more rigid.

    More of an optical illusion. It is correct just so you know.

    I am at the moment, but will be changing over soon.

    The turn fin is fine, just need a better mount.

    Good news, I took the boat out to day for more testing and tuning. I installed my own version of an air dam and I have to say not much different with or with out. I still have more testing to do and hopefully I'll come to appreciate the air dam.
    I did run across a minor glitch in the cooling system, I found that some debris in the line after the esc, it was blocking the line which created more heat than normal. I cleared the line and made another run and all was much cooler.

    I'm working on a couple videos to share with you so you can see where I'm at with the boat. I'll post the links when there ready.

    Good to hear you found the block and part of your heat problems,
    Try to stay out of the green stuff and muck it grows in or you may have more blockages.
    You should pull the water jacket once in a while and look for sand and stuff like that in there to,
    The boat looks to be running a lot better the way it should in that video.

    Thanks lenny, I was happy to find the cooling system blockage. While I was running the boat I felt the the turning was not quite solid. This is why I want to make a more rigid mount for the turn fin. I know it's not thebest video, but I didn't have anyone there to record for me. This is why I had to use a mini tripod that's a little to close to the ground.

    Anyway, I am happy with the results of the run. More video footage to come.

    Hear an idea for you,
    And this is how I do just about all my video's.
    I just aim it like a side are gun and move my tx where the boat is going,
    It gets easier the more you do it.

    And this was with the old camera I used.

    Thanks, the lake is a cool spot to run, not a lot of traffic.
    The prop in that video is stock, the next video will have a GR 40X52 on her.
    I can't for the life of me figure out the 40X57. Can't get it right.

    What are you running for electronics, stock? What size batteries are you running and where do you have the installed?
