    Miss Geico-What Works For Me

    There has been a ton of information listed here on OSE regarding Proboat's Miss Geico. I wanted to take the time to show what I have done with my set up so that other Miss Geico owners might be able to gain some possible insight. To preface things a bit, I am a sport user, not a racer. I love speed, but not at the price of small scale nuclear explosions. Reliability and enjoyment are of paramount importance when it comes to my FE rigs. Out of the box, Proboat's Miss Geico is a fantastic boat in terms of build quality, performance and ease of operability. Having said that, some things are left to be desired. Namely, the porpoising. By trial and error, I have found that the porpoising is caused by the stock in-line rudder configuration and nothing else. I tried multiple props, COG adjustments, battery placement and what I found was that an offset rudder configuration eliminates the porpoising 100%. I ordered the Kintec Racing offset bracket and it works, except that it introduces a significant amount of drag which I found to be unacceptable. I ended up altering the Kintec design by removing the bottom portion of the bracket as shown in the photo below. This kept the bracket out of the water line and eliminated the drag. I also installed an aftermarket rudder which is 4" in length versus the stock 3.5" rudder. This change brough back the amazing handling that was somewhat lost when I originally offset the rudder in the first place. The next modification I did was to remove the stock power system. Now don't get wrong, the stock PB 1500 motor and ESC are damn near invinceable at 4S but I wanted more speed without having to tweak the heck out of the stock components. This means I didn't want to blueprint the hull. After consulting with Steve at OSE, I chose the Leopard 4074 2000kV motor and Hobbywing Seaking 180 V2 ESC. This duo, combined with a S/B/P Octura x642 prop nets me speeds in the mid-fifties every run. The temps are luke warm at most and that is considering the fact that I have 5.5mm bullet connectors on everything. I am also not using the BEC and have opted to use a 1600mAH NiMH Rx pack instead. My batteries are (2) Zippy Flightmax 5000mAH 2S 40C packs for a total system power of 4S (14.8v). Based on past perfomance baselines, I decided to stick with my trusty Tactic 2.4GHZ Tx/Rx combo because I loathe antennae's. Differrent strokes for different folks there. This system set-up lets me run in the mid-fifties reliably and safely every time I go out and I always come back with a huge smile on my face because I didn't sink the boat or cause any explosions. Thank you to all of you who have posted here because you have given me a lot of valuable information and further enhanced my love of this incredible pastime!

    Nice write up! Few questions..

    Did the motor drop in with the stock mount? Any clearance issues with the sub hatch?
    What make hatch lock is that? Looks nice.

    Also, I like the grease splatter shield you made.

      The Leopard 4074 motor bolts up perfectly to the stock MG motor mount. I did remove the blue anodizing so that may have thrown you for a loop. There are no clearance issues at all with the larger motor as long as you route the wires along the side of the can and not on top of it. The motor has multiple mounting configuation holes on the end bell. I made the hatch lock custom with a SS 8/32 machine screw and a threaded T-nut. I removed the barbs from the T-nut and used JB Weld to attach it to the inside of the hull. I then used 2 o-ring seals on the screw itself and just finger tighten it. It simply works fabulous and I no longer need to tape the canopy down.

          If you think this boat is a blast on stock power, wait until you go full throttle with the Leopard - I found out real quick that I needed a bigger lake!

            Yeah I can imagine. I have a vac-u-pickle that runs in the 50s. The geico would be real fun at that speed!

              Your off set bracket design is the best I've seen. I mentioned in one of my recent posts after testing the Kintec racing rudder off set kit, that I was correclty concerned about the potential for the lower portion of it creating drag. It does.

              I really like your design over either the Kintec or using the 2 Octura spaces set up.
              The off set is the key to having a smooth ride on these boats. I am wondering if 120A Turnigy ESC would work with this combo..

              Thanks for the post. Always good to have good documentation

                I would not use the 120A ESC with the 2000kv Leopard. I pull 100 amps with this set up so it is nice to have headroom. My motto is, "over engineer, under utilize".

                      Todd, just modify your kintec bracket. That's what he did. Looks good!
