i've also been tracking these new series closely - esp with Ian Allan terminating Yefim Gordon's magnificent Red Star and Famous Russian Series - i had high expectations in this new Flighcraft series from Pen & Sword
Both these books have been released in late Dec in the UK - i've seen these at Foyle's in london and unlike most of the Gordon's books - i've discarded these as being skimpy in content though the printing and layout meet the expectations
For instance in around 90 pages on the Gunships - the Hind, Hokum and Havoc are all covered - potted history , tech details , walk around , some profiles not enough for the discerning reader or the serious modeller
So if you dont have any of the previous Aerofax/Red Star/Airlife/WAPJ series then i would recommend the Gun ship book else even Alexander Mladenov's Mil 24/35 released by Osprey has far more detail for half the price and a good buy
