RE: Flair Puppeteer Build
About the sound generator .... 50mm speaker is a fraction less than 2", ok that can handled but how are you going to get 9-18 volts of power? Are you going to hook a couple of 4.8v or 6.0 batteries in series. Machine gun sounds may be wonderful if they can be heard over the engine (unless using electric motor), but the weight of 2 (or 3) extra batteries plus the weight of the sound generator (not given in description) may make this impracticable IMHO. Interesting idea. I'm curious for more.
