I got the RDA Gunship from the Avatar line yesterday and it's okay. but i have had this idea in my head of getting a second one after they go on sale and trying to mod it to look more like a real helicopter. At the top of the toy there is a lot of space for a shaft so that a large main rotor could be put in. my questions are basic: 1. I want to keep the project simple, so would it be easier to make it a standard chopper -main rotor and tail rotor- or a coaxial chopper like the Kamov: 2. Any suggestions for the parts? I didn't want to use the rotors from the Gunship. The rotors from the RoC D-hawk are about perfect because the 2 aircraft are almost the same size, but that toy has been damn nigh-impossible to find in this area and I didn't want to bust up a great $25+ toy for this. 3. So is this a pretty basic, simple, easy project? I don't want to do anything fancy other than have spinning rotors. *they be spinnin'!* Any help here would be appreciated. Thnx!
