Started on hubsans x4s then bought a runner whilst I plan and build an Fpv racer.
There are issues with the runner notably:
The frame isn't pure carbon fibre but a laminate, add to that the top and bottom plates are only 1mm and the power board is part of the structural integrity and it isn't particularly crash resistant,
It has the flip of death
Fail safe out the box is "run away never to be seen again"
But that said, it is fun to fly, I have banged it into the ground many times and it has no problems (in fact I haven't even broken a prop, although they are not as straight as they once were)
I have thoroughly enjoyed using this as a "learning to fly 250 drones" machine/ learn Fpv
If you buy one, there are a number of things you need to do before you fly, these are thoroughly documented on you tube but the main ones are:
1. Switch throttle failsafe
2. Set throttle hold
3. Up the throttle trim to avoid flip of death
4. Fix id
You are going to need spare props, spare batteries and you will want a better charger than the one provided
Otherwise, I agree, get a nano quad and learn how to fly first, don't expect to be Charpu and you can have fun with this quad
