Mamba Max - Radio Question
I just got a Mamba Max and installed it in my Kyosho Lazer. I was testing it out in the backyard, stop/go, turning, basically just driving around slowly when i decide to test the acceleration. I have a 60 foot driveway and I accellerated down the driveway, when I got to the end of the driveway I let off the throttle and to my horror the car just kept going. It flew over the sidewalk and hit the middle of the street heading right for the curb on the other side of the street. Luckily it hit a small pothole and flipped over and the battery flew out and killed it. I did not have my transmitter antenna extended (since it was only 75 feet), but it seems like the radio lost it's signal and the car went off by itself. What I am confused about is on electric cars, if the signal is lost won't the car stop (no power to the motor) by itself? I did some testing (which I should have done before hand), by placing the car on a block and walking away while giving it throttle, at about the 60 foot mark the car all of a sudden started to glitch/accelerate by itself. I had the antenna down for this test. I then extended the antenna and I regained control over the car and it seem to work normally at extended ranges (100+ feet). My question is why did the car take off by itself? Is the Mamba Max sensitive to rx signal strength? I calibrated the Mamba per instructions and it ran fine when I was setting it up, I am using a JR XS3 Pro radio and JR rx, using fresh batteries all around. Any ideas?
