Thanks for the comp. I'm running a hopped up 36cc scooter motor. I started off with old octura strut and rudder, but the rudder was way too small. Therefore I scratched me out a twin rudder set up out of brass plate and tubing
But the first time i ran wide open throttle and threw a hard turn in... I snapped them off
So now I'm upgrading that to 3/8 ss tubing and ss plate!!! If that don't hold up.. I'm going down to Mike Marine Works and buying a Hobie Cat rubber for it!!!!
Could ya imagine? I've also got another gadget I'm working on...REVERSE
!! This pic is just my proto. The finished product will be out 1/2" plexiglass laminated and bolted together so I can make it water tight and put a light weight oil in it. I'm also designing a gear box to allow for twin screws!!!!!! GOTTA LOVE IT!!!!!!!
When the 3 gears on the bottom are in line like they are in the pic... that's forward. Flip a servo (STRONG SERVO)
the smaller box in the box brings the top gear down...WALA reverse!! And the prop is the biggest I could find on the web!!! I want to go to twin screws so I can put 2 270's on it. Should have plenty of power. The motor slings that monster prop like it not even there!!! I had it semi surface drive to start with...Way too much cav!!! After dropping down about 3/4" it jumps out the water when I shower down on it
My only concern about the twin screw idea... I don't know if the single shaft to the gear box can handle... Because I plan on stepping it up about 25 - 30% on the ratio.. Any suggestions?
