It is indeed stock except for the antenna. It flies like a brick unless paired with an Ampace JP30, the Sony VTC6 I find to be limiting its performance.
I am considering upgrading the engines to something with a bit more torque, it is currently running 1202.5, I might try upgrading those to 1203.
If a motor upgrade works out well I'll likely also install a separate ELRS RX to improve the range, although up until now I have never had any issues with the stock SMT antenna.
I really like using it for just cruising with its 10+ minute flight time.
