use caliber II trucks on amazon. 10 inches are best https://www.amazon.com/Caliber-Truck-Co-Skateboard-44-Degree/dp/B00J5J6B0U/ref=sr_1_1?s=sporting-goods&ie=UTF8&qid=1509123167&sr=1-1&keywords=caliber+II+10+inch
Use your favorite motor mounts Dual on 1 truck would probably work, but I like the setup of a diagonal setup (ie one on front right wheel and one on back left wheel)
