long radio range.....like 40-50 FEET.
buy both blue and yellow. you then can race/combat each other on 27 mhz and 40 mhz
it's like 3D chess...........note in my 180 gallon (2x2x6') fish tank, I've hung 6" speaker rings, and some fishing floats for gates to carve through.
Note being both a Scuba Dive Instructor, and Anall Engineer, I zip tied a nut ballast in front of the Conning Tower, so you can then slide forward or back to perfectly trim out for level running. Nut, I grinder'd down lighter it for perfect weight.
Remember, the above, has a bladder. full micro control at neutral buoyancy.
Has a Stern Side Thruster for steering. single screw rear.
SPEED DEMON
If you want a micro sub race car, these are FAST
note, I bought a blue and a black....they both came on same freq. 27 mhz . can't run both.
