Aside from the radio I'm not sure why you've listed the MMM 10.5 speed passion motor
I believe that combo is about £20 more than the normal 'grey can' V3. If you've purposely chosen a slower motor wind there seems little point in buying a quicker version of a slower motor. An 8.5 'normal' V3 might be a better bet & could last you longer...
I'm sure that £20 could be better spent on other kit
