As an armour nut with an interest in all things associated with that Vietnam conflict, I've long been looking for a decent UH1 Slick.
The MRC UH1 Gunship Hueys have been around for some time and are supposed to be pretty good (I've yet to buy or build one though... opinions posted here gratefully received)
The old Revell UH1H is, well, an ooooooold Revell kit with all that suggests...
My guess is that combining the best bits of the Revell kit with the relevant bits cannabilised from a donor MRC kit would be an exercise in masochism I wouldn't want to inflict on myself, disregarding the the 1/32 to 1/35 scale difference.
I've heard that a company called Panda is releasing a UH1D Huey in both Slick and Gunship versions :-) which is Very Nice, but so far all I've heard is a rumour

If anyone has any news of this new offering, I'd love to hear it!
Failing that, opinions on the utility or futility of trying the MRC / Revell kitbash...
Okay, time to hit the glue bottle...
