This is the 24 gram, 0703 KV15000 brushless motor version of the Trainer90 BNF kit. In the box of parts I found 2 sheets of paper showing wiring diagrams and the steps needed to bind the receiver to a transmitter. The model is assembled as shown in the pictures. It is important to note that the bottom end of the motor shafts must be supported while pushing on the props. I've already made a few modifications. The 3D printed camera mount was replaced. The receiver board is now part of the stack. And, snazzy new 3 blade props. The power supply is a "Whoop" style stick battery so the fun is interrupted every few minutes. The main board is a combo flight control and a 4 way ESC that eliminates wiring and compacts the setup. Solder connections are on the top and bottom of the board. And, inboard mounting holes let the board fit onto the 16mm x 16mm stack. It overhangs but the ESC solder pads conveniently line up with the frame arms. Iíve tightly wrapped the slender arms with vinyl tape which also protects the motor wiring. Otherwise, the electronics are typical for a micro these days. Using Betaflight OSD, adjusting the PIDS and rates while flying was faster and easier than going back and forth to a computer. I really like that feature. My configurations and transmitter setups have gotten more sophisticated lately but that is a subject for a different post.
Flying around the apartment, it is safe and durable even without propeller guards. But, I fly away from people, pets and delicate items. It has more power than needed. Outdoors, it is light, airy and beautifully acrobatic. Now the Trainer90 name makes sense to me.
