That's your problem. Stock v2 prop needs a lot of RPM from the small 6mm motor to work. Compare to the stock 6mm motor, the hp03t runs a much lower RPM but much much more torque. It needs a prop that runs about 58-68mm with pretty high pitch profile. The RRC prop works best. Alternatively, Walkera 4G3 tail prop or a cut-down to 59mm 120SR tail prop custom bent for more pitch and progressive pitch profile also work. A non-cutdown or non-custom-bent 120SR tail prop will work marginally. A stock v2 prop has no chance.
