Kayoumini 2.5 Analog

After building two digital KayouMini 2.5 quads, I set out to craft a lighter, nimble analog version. This build features T-Motor/T-Hobby 1103 8000KV motors, a Caddx Baby Ratel 2, and an all-in-one Happymodel X14 AIO board with VTX and ELRS. With a GNB 380mAh 2S battery, I hit my weight target, and the result is a nimble backyard freestyle machine. Though I love my DJI builds HERE, this one is perfect for tight proximity flying.

Build Tips:

For those who may not know, T-Motor is now T-Hobby. I ordered the 1103 8000KV motors from AliExpress. The motor shaft is quite short and requires screws to secure props. I used M2x7mm titanium screws, and they worked perfectly. I also used M2x5mm to secure the motor to the frame.

The Happymodel X14 AIO board has plugs. I removed them by bridging the three pins with solder, locking pliers onto the plug, heating the joint, and pulling it out. Quick, then I cleaned up the solder. Image below.

I direct-soldered the camera wires on top of the board avoiding the ESC area. Twisting video and ground wires together and separating the voltage line gave me great video quality.

The Caddx Baby Ratel 2 plugs hit the top plate using the 30° TPU mount, so I flipped the camera upside down. After mounting, I used the OSD joystick to flip the image upright. I also switched to NTSC for lower latency and I'm super impressed with the image quality.

I began with the KayouMini 2.5 starter tune HERE. It was a solid start—after filtering out prop wash and applying Bluejay ESC settings, it flies smooth and nimble, just how I want.
