| This was a blank Graupner Electro Vee I ordered from Hobby
Lobby, just $25 I knew the paint scheme right away for this boat. The paint style was designed on my computer before painting it. I didn't like the two driver look that is suggested, I cut the top cover to look like a cock pit, I made the windshields from an old floppy disk holder and glued from the inside. The interior mounts were made
from plastic computer data tape holders and aluminum angle for the motor mount. |

I repaired the nose and installed a 400amp ESC, it did not run as fast, so I reinstalled
the
MRP micro switch mechanical speed control and made a receiver power cell from a laptop battery, 3600mah, I only need to charge it
once a month. The boat ran good for most of the season, but the MRP controller failed, not sure why, so I pulled it and just put a 20 amp switch in, it's either off or full throttle, I also decided to see what would happen if it was wired to send 14.4 volts to each of the 8.4 volt motors. It was our final race for the season, the boat took off and got on a plane right away and was 30 feet ahead of the pack after the first lap, on the last turn of the second lap it spun out, two complete 360's and the set screw on the out drive came loose, I retrieved the boat and was able to retighten the set screw as the other boats were making the turn, I knew I had lost the race but needed to finish, the batteries must have been so hot that the torque to get it up on a plane was more than it could take, it started billowing smoke as it came to the finish line, one of the batteries, switch and most of the wiring completely melted. I just finished bringing this boat back on line, replaced motor wires back to the inline configuration (see Controls & Wiring) New servo mounted switch with in-series battery harness, it only knows off and full throttle at 14.4 volts. |
