    New motor... same speed

    ok so i got a NQD PX-16. I changed the stock motors for two Titan 12T but it goes the same speed. Is this cause it's getting the same rpm's from the esc? the titan's are literally twice as big as the last ones. If it's the rpm's then the bigger motor's should have more torque and be able to handle bigger propellers right? would this make it faster? i also had someone mention the pitch. Any help would be appreciated cause i broke the motor mounts putting the new ones in and took them off my trucks lol.

      If you are using the stock props that came with it, you will very likely not notice a speed increase. To use other props, you will either need to make adapters or change the drive system altogether. But doing so will tax the Reciever/ESC unit that is used in that boat. You could take out the dual motor setup and put a single 540 brushless motor/ESC combo with a single flex shaft and drive hardware. But if you are going to go thru all that trouble and expense, you might want to invest in a hobby grade hull and hardware.
      Been there, done that with another dual motor cat from ebay.

          yeah that's the one. I got it for my oldest boys 7th b-day. Box says it goes 15 mph, i was pretty impressed,being the first r/cboat i'd seen other than those radio shack ones.
          The Titan 12T is made by traxxas, like the fastest one without going brushless. And yeah if i were really into it i'd get a whole new project to work on but i'm notinto spending a ton of money right now... i was just bored and had the extra motors.

          What does "tax" the esc mean?
          wouldn't it be on the motors that are bigger and more powerful anyway?

            "Tax" means overload the unit. The motors with more aggressive props will draw too much current for the Receiver/ESC unit to handle. It will more than likely burn up.
