Thanks for the replies so far!!!

The transmitter will be for my Micron V2, since it doesn't come with one. But I want to be able to use the transmitter for all the cool RC machines that I plan to get in the future. So far, my hydrofoam and dragonfly have their own transmitter(s) and the F27c Stryker that I'm about to get also comes with it's own transmitter.

Will it be possible (with the right crystals) to operate the dragonfly, hydrofoam and Stryker with the Hitec Eclipse that I want (so far)?
