For both I recommend HeliAir!
I wouldn't recommend HeliAir for
anything!- nice guys 'on the floor', but the management are aggressive, arrogant and greedy. I took my machine away after they tried to slap a £2,000/year 'part M' charge on me for looking after my
brand new R44 and would recommend all other owners do the same. My new maintenance organisation charges nothing for part M, and almost 30% less per hour than HeliAir.
