Back in late December I began my latest project - a counter rotating bladed helicopter. It has been a significant project taking well over 200 hours. I finally finished it last night. It is made from lots of recycled parts including a Play Station controller, apple sauce packet caps, some sewing button caps, parts from a VCR and electronic circuit board parts to name a few. The hardest part was getting the gears to work with a motor to turn the rotors in opposite directions. I had designed the rotor shaft to turn a perpendicular shaft going back to the tail to turn the tail fans as well, but they were just too small to get the gears inside, so the fans just spin freely. The doors and back ramp open and close and the whole mechanism turns smoothly and quietly. The tools used inclded my main go to Dremel 4300 Rotary Tool and Drill Press with a huge assortment of accessories. I also used my Router Table, Moto Saw and Versa Tip torch for some soldering.
