No such room in this tank.
Instead I modified my tank to get outside air from the front and to get it out from the rear hatch for good ventilation as in the pics below.The blower fan powered by 12 V lipo is so powerful enough to cool the two motors intensively inhaling outside air
and exhaling it from the rear deck hatch.With this cooling system,the tank could run on the rough terrain in the early June of last year once. I myself got too hot rather than the tank and I did the trial run only once so far...
1;This is a sub-air intake I opened.
2; This is a main air intake.
3/4/5;A large part was set for air intake under the hull front to take as much air as possible,but it is hardly seen from the front.
6/7/8;Rear ventilation hatch was also set to exhale the cooling air. This part is also hardly seen when the turret faces the front.
