FMS J11 Twin 70mm EDF Review: Flight Time, Setup, Battery and Real-World Flying
The FMS J11 Twin 70mm EDF is a large, highly detailed single-6S twin jet with realistic flight presence, strong speed and excellent 12-blade EDF sound. Its main limitation is short flight time, so battery weight, CG, telemetry and landing reserve matter more than capacity alone. This guide covers real-world handling, runway needs, 5000–6200mAh LiPo setups and lightweight 6700–7200mAh LiHV options for pilots who want more usable reserve without the usual high-capacity weight penalty.
