Outbit Flight Controller Stabilizer - F50A 3-Axle Gyro A3 V2 Flight Controller Stabilizer System for RC Fixed-wing Airplane

Very good value

This is a great flight controller for just about any casual or hobby flyer! It's small enough for a lot of models but will require some tuning to get the gain settings correct for your model. I put one of these in a Strix Nano Goblin and after fussing with the gains for about 10 minutes, I got it to fly VERY nicely in auto-level mode.If I have to nag about something is the quality of the case. Way too cheap and pop open easily. I had to add glue around the seams to keep it closed. Maybe the manufacturer could use in the future the same case type from the A3S2 ?

I got two flights out of this unit before it decided to play up. I had it set on Flt Mode 2 (normal-off-auto balance) on a 3 position s/w. During the 3rd flight I could not s/w it to OFF. Following a twitchy landing, a ground check found it had gone to an "unknown" mode, which operated as follows: Auto Balance - normal - auto balance with no OFF. No matter what I did I could not change this configuration, therefore the gyro was disconnected, removed and filed under 'B'. Note to self: Don't buy cheap offers even from Amazon.
