The A700ex is already there in Mod racing. It's just that the pros need to stop using those powerless 4.5t motors and upgrade to a 2.5t boosted !!!!! The car can't reach its potential if you follow the belt cars... You need to recognize that the belt cars will never be able to handle a 2.5t boosted without overheating, but the shaft cars can handle it with ease...
DON'T HOLD THE A700 BACK !!!
