I bought a slayer a few weeks ago. I have had great fun with it. Unfortunately its been a little cold and snowy out so its been in the house for most of the time. I had some time and I found a parking lot with some dry asphalt so I took it out a couple of days ago and again today. In both bashing sessions, I noticed that the distance that my transmitter reaches is not to far, I would say probably no more than 200 ft. I have a slash and it works for almost 500 ft. so I am a little surprised to see this. I tried changing the batteries in the transmitter and receiver with no improvement. Is this normal or is there something I can do to increase the range?
