By far one of the craziest entries for The Hackaday Prize is [Peter McCloud]’s Goliath, an enormous gas-powered quadcopter. It weighs about 240 pounds, is powered by a 30 horsepower v-twin lawnmower engine, is lifted into the air with homemade props milled on a CNC machine. It’s a frightening build even when the engine isn’t turning. When running, it’s an awesome display of power and technology.
Goliath has had a few setbacks of late, snapping two composite props in its first attempt at hovering. This hasn’t deterred [Peter]; he’s picking up the pieces and he’ll have this monstrous quad hovering in a week or two. A good thing, because the judges are paring the quarterfinalists just three weekends from now.
Check out [Peter]’s bio below.
Goliath currently takes up most of my free time but I also enjoy going out on our boat wakeboarding and tubing each summer. I also swim, kayak, skateboard, snowboard, read, travel and have my private pilot’s license.
I work for the Aerosciences Branch at NASA Johnson Space Center as a contractor. I mostly do aerothermodynamics, using Computational Fluid Dynamics (CFD) to define the heating environments for ascent and entry.
I’ve had the chance to work on Shuttle, CST-100 and Orion.
I really enjoy building things, especially if it’s space- and aviation-related.
My 2001 Toyota 4runner. The check engine lights are always coming on (they are on right now) and I’m constantly having to work on it. I’ve replaced the head gasket twice, done an engine swap, replaced the catalytic converters and a dozen other things. That being said, it’s a useful vehicle with it’s cargo space and towing capability.
While I have experience with electronics, I don’t do a lot, so my sole piece of electronics equipment is a Craftsman Multi-Meter I was given as a teenager.
The pieces that make up the 48GB of memory installed in my Linux workstation at the office.
Python, followed by anything else that’s not FORTRAN. While working on the Shuttle program, I had to work with FORTRAN programs that were formatted for punch cards, on which the programs were originally written.
- Eventually a bigger version of Goliath to carry people
I had just started building Goliath a few months before THP was announced, so it was perfect timing.
GimbalBot. It’s pretty cool looking and [zakqwy] is doing a great job documenting the project. To me, he’s the ideal Hackaday member because he provides great feedback and does a great job of encouraging other people with their projects.
It’s not coming along perfectly. As the latest article described, I’m frantically working to get two new propellers built and to find the right one-way bearings. I can’t say that wrecking two of the propellers was completely unforeseen.
I did fully expect to damage something during all the testing. Like my wife pointed out, at least we didn’t have to use the fire extinguisher that we had at the ready. Projects like this aren’t going to come out right the first time.
I’m really impressed by all the projects and hackers that are on the site. Also, if it wasn’t for my amazing wife, building Goliath wouldn’t be possible.
