  • Not So Rapid Prototyping
  • Log     from Goliath - A Gas Powered Quadcopter
  • I haven't been posting build updates as frequently because the build activities have mostly consisted of sanding....lots and lots of sanding.  The good news is that I'm nearly complete with the first flight quality propeller!  I've talked previously...

  • Finishing the Propellers
  • Log     from Goliath - A Gas Powered Quadcopter
  • Over the last week I completed doing the fiberglass layup for the 3rd and 4th propeller.  Cutting the cores and doing the fiberglass layup for the propellers was one of the biggest parts of the project and it's good to have it out of the way.  The...

  • Redesign Progress
  • Log     from Goliath - A Gas Powered Quadcopter
  • I've been working on making changes to Goliath.  As I discussed previously I had suspected the need for a one-way bearing to prevent slack from occurring during a shut down.Helicopters use one-way clutches to allow for auto-rotation after an engine...

  • Testing - Round 2
  • Log     from Goliath - A Gas Powered Quadcopter
  • 10/15 UPDATE: Good 3rd Gas Engine test! See bottom for details...Ok, so things are finally in a good state to start doing the second round of testing. As I did before, I'll be updating this project log as I go, instead of making multiple logs. I'm trying...

  • Test Stand (The Octagon!)
  • Log     from Goliath - A Gas Powered Quadcopter
  • After going back and forth on how to rig up the hover test, I decided to go with a large test stand that will enclose Goliath. I've nicknamed it The Octagon cause it has eight sides and saying The Octagon reminds me of Rex Kwon Do from Napoleon Dynamite.Anyways,...

  • Settling into the new place
  • Log     from Goliath - A Gas Powered Quadcopter
  • I've been busy for the last month getting settled into the new house and getting Goliath unpacked. I had been hoping to transport Goliath in one piece (minus the oil and gas), but after the movers arrived and saw everything that was going to be packed,...

  • 35 lbs short
  • Log     from Goliath - A Gas Powered Quadcopter
  • Thrust measurement and weight reduction has been the focus of the work on Goliath over the last few weeks. Prior to the last test, Goliath weighed 238 lbs, about 40 lbs more than the target weight when the project started. With the vehicle design still...

  • Latest Tests Completed
  • Log     from Goliath - A Gas Powered Quadcopter
  • The latest testing with the new rotors has been completed. However, Goliath still isn't flying. Most of the testing was troubleshooting Goliath after reassembly. It seems that a few tests are always required to get everything setup up correctly when...

  • Designing Custom Rotor Pulleys
  • Log     from Goliath - A Gas Powered Quadcopter
  • One of the goals of the project is to use as much off-the-shelf hardware as possible. The prior rotor pulleys were standard pulleys and readily available. A few of the issues with the prior pulleys were that they were made of steel and required a separate...

  • First Custom Pulley Finished
  • Log     from Goliath - A Gas Powered Quadcopter
  • The first of the custom pulleys was completed today. The custom pulleys are aluminum instead of steel and allow for six fitted mounting bolts instead of three fully threaded bolts. Here's an image of the new custom pulley connected to one of the previously...

  • Bearings and Axles
  • Log     from Goliath - A Gas Powered Quadcopter
  • In the previous project log, the first of the new rotor pulleys with the new axles had been tested. The new hardware was considered to be good because nothing broke (yes, not breaking is a low bar to set). The next step was supposed to be assembling...
