yea, thats the funtec branded Hitec model, $140 is waaaaay to steep, I wasn't even willing to pay $80
especially because:
1) takes 1 hour to charge the sub
2) runs for 10 mins
3) no up/down control, if the throttle is going forward the sub goes down, if you reverse, it goes up, and also since steering is controlled by the props it rises when you make a turn
now the bit char-g sub on the other hand looks to have up/down control like an airplane/normal r/c sub (note the little joystick on the top of the sub's controller, that my geuss is for attitude, much like the 3 channel hitec Focus III airplane controller has)
I want a submarine
