How TQ Motors Enhanced upstair’s Prototype

The first upstair prototype used outrunner motors, which lacked the necessary form factor and technical specifications. By switching to ILM-E85x13 and ILM-E85x23 motors, upstair reduced weight, improved compactness, and ensured full sealing. Additionally, TQ’s German-based support provides direct assistance for technical questions, a major advantage for the upstair team.
