J&H Aerospace is pleased to announce the introduction of our new carbon VP hub for F1M. At less than 300 mg it is very light, yet robust enough to handle the high torque values common on F1M models. In fact this hub is stressed to handle the launch torques of Open Pennyplanes. Adjustment screws are provided for all three common adjustments on indoor VP hubs, and spar tubes for 3/32″ propeller spars can be installed for no extra charge.
