Quite frankly, two motors is cooler than one. Nothing like lifting the hood and having two phat cans sat there.

Every truck I've ever seen with 2 motors hasn't really had a problem. Traxxas has to account for every eventuality if they are thinking of releasing a product to the public, hence the sync cable.

If someone builds a custom truck with two BL motors then they are likely to not mind repairing the damage that this setup can do. If you are going to release a truck to joe bloggs on the street, with a warranty then you HAVE to make sure it works under normal conditions without failure. The sync issue isn't huge, but a truck that will randomly sheer spur inputs or motor shafts every now and then isn't something that the average bloke/girl on the street with a fistful of $ will necessarily want to deal with.

Me, Access, Dan, J.D.T etc. won't have an issue. Incidentally I once fitted 2 feigao 9ls in an E-savage. It was insane but the drivetrain was screaming for mercy after around 40 seconds.
