I've been trying to get answers from Horizon now for a couple of weeks and so far all I've gotten is an auto reply saying that someone will contact me within 48 hrs. I just want to know if they are even considering a firmware upgrade that will put the Xcelorin on par with Castle's product as far as fixing the cogging and braking issues. The brakes just will not cut the mustard when running with the fast guys. You really need to be able to finesse the car in the air and right now that is impossible. Please, for the love of cheeses, somebody tell me there is an upgrade on the way so I don't have to give up my beautiful system that fits my car like a glove. I'm just about ready to put the ole Mamba Max in my ride until I get a yes or no.
