While I was down in FL I made a stop at Warehouse Hobbies. They make large scale boats and accessories for them. Two of their newer products are perfect for 1/5-scale vehicles. The EKG prevents runaways by shutting your engine down if it detects a drop in receiver pack voltage or a loss of voltage all together. And their new clear gas filter allows you to see if you have fuel in the system and you can easily see if there is debris inside. Check out www.whobbies.com for more products that you can use on your gas vehicle.
