ALES is, by definition, an ELECTRIC event, so I'm going out on a limb by saying no fueled IC motors allowed. As David is the Nats XC CD, he can speak to those rules in particular.
Thanks for jumping in Tom, you are correct on both counts. The ALES class must follow the 5Kg weight limit, electric motors with 200 meter limiters.
