10mph in modified flip flops (3 min 37 sec)

Was quite pleased by how stable it was at 10.9mph. For most of its life, it couldn't go straight at 10mph, even when completely empty. It now goes straight even with a camera pole on it. Better living through FIR filters.

Just a quick built F22... 21 inch wingspan... Cut the plans out, traced them on the foam and cut the pieces out. All done this afternoon. Power is a 1350 Kva motor turning a 6x4 APC Prop with a 30 amp ESC on a 3 cell Lipo. Should move along nicely!


Plans are for a Nano F22 that I blew up to 400%

Boycott Traxxas

Posted by bill_delong | Yesterday @ 01:29 PM | 426 Views
wait... what... why on earth would anyone ever want to boycott one of the largest most influential R/C companies on the planet???

Let's take a step back in time to see where Traxxas was founded back in 1986 by Jim Jenkins and David Katz. Traxxas is credited for introducing the concept of a RTR and bringing the Short Course class into R/C among many other cool concepts.

In contrast of amazing contributions that Traxxas has made in growing the industry, they have grown into a completely different company from what they once were and have morphed into a "Patent Troll" who is focused on destroying their competition which is now killing the industry as we know it. So what is the definition of a patent troll and what sorts of things has Traxxas done to categorize them this way, I've highlighted key actions that Traxxas is guilty of doing here:


1) Baseless Claims - I need to do more research because Traxxas has filed too many baseless claims to keep track of them all, but I will point out 2 key events that have dramatically impacted the industry. First was around 2014 when Traxxas sued HPI for patent infringement by using a rubber seal to copy their idea for a "waterproof Rx box". Keep in mind that HPI legally reverse engineered the design and came up with a new shape/geometry with no direct copy molds. In theory this case should've been thrown...Continue Reading

I often find Classical music relieves the BS of all the nonsense that occurs in our lives. TT is cursed with negative energy. I hope this link will provide some positive energy. Beethoven composed this in the years that he was facing deafness.

Here are two models based on the Lynx OXY-3.

The OXY-3 is built as the 255mm version.

The OXY-X Speed Qube (pronounced Ten) is a fantasy chopper based on the OXY-3 Speed shell with the Qube (triple) head and tail combo.

I say fantasy as she is built at 2m length with a turbo engine. One can dream?

They can be downloaded here.
