As stated above, mixing 1/35 vehicles with 1/32 aircraft is not an issue. Just keep constant items such as weapons, packs, canteens, etc. in one scale (usually 1/35 since there are more 1/35 figures). You can mix 1/32 and 1/35 figures as well, since people come in many different sizes, but gear is pretty much a standard size.
As to 1/35 helos, there are lots of them:

US Army UH-1C in 4 different boxings with a variety of weapons configurations

Dragon:
OH-6A, AH-6J, MD-500, MD-530

Revell also has a bunch of 1/32 helicopters that are pretty good too. These include a UH-1D/H Huey, AH-1G Cobra, OH-58A/Bell Jetranger, and a bunch of European helos to include the EC-145 which can be made into a US Army UH-72A Lakota.
