1 - None on mine.

2 - None on mine also, as it is fitted with canards, the CG shifts forward and the steering wheel keeps well grounded as also I fly on tarmac.

3 - Yes, it flies pretty well using VT´s doing tumbles, harriers, etc.. however I still prefer how canards behave on slow flight instead VT´s assist. (I tried quite successfully this, however the first time the engine quit and I lost 50% of pitch control authority while trying to reach back the runway made me put the canards back, LOL)
