hey anybody that waterproofs their electronics with balloons DO NOT use balloons on your servos, i used balloons on my servos, reciever, batter holder, and even my failsafe.. i just took the balloons off my servos cause i was trying to figure out a problem i was having with my electronics, and inside the balloon it was all wet and i think that was the problem, the batter holder, the reciever, and anything inside the tray was not wet inside because the tray is inclosed..good thing i have spare servos
