Bigaole V3 3-Axis Flybarless Helicopter Control System with Sbus& Satellite (BGL007-008)
[BGL-8]

This fbl unit is great, the setup is so easy and the performance is stunning, and with the addition of satellite support it's an even better model than the previous version. I'm running one in a raptor e620 and I'm currently setting up a second in a hk250gt. I'm already planning on getting a third to convert my hurricane 550 to fbl, at this price it's hard to resist :D
