"Chinook and Mi26 in 1:35"???? My my, those darn Americans with their biiiig houses!
A 1:35 Mi 26 wouldn't even fit in my country, let alone my modelling room!
Apart from a (re-) release of the MD500 series in 1:35 I'd stick to 1:48 and ask for civil stuff:
AB139, B206L, B407, B214ST, S76, S92, AS332, EC155.
