No EPA - I am in the middle of noware with a bunch of land.Im wanting to make a quiet heli that can hold the gear I want it to hold.I want to be able to mount a movable infared/color camera and operate it through a laptop.I also want to be able to have the heli do some tasks with minature robotics equiptment of my design.I was thinking if I could get a basic working unit down then I could design and make a few units that would be able to do a few things that could be of benifit as working units for others.This is all just a pipe dream in smoke now but I always try what I dream up.Sometimes it works Ill try something like it I was just wondering if what I have available now can be converted or if anyone has tried and what the pros and cons were.
