It's been a good while since Gearbest have had any good quad specials on, I noticed their website has improved so maybe that is where the focus has been. Anyway I've posted my pick of specials below at http://quadifyrc.weebly.com/coupons-and-discounts.html

I like the fact that both the TX200 and an OEM CCD micro camera are both on special meaning you can upgrade your AIO camera in your brushless micro to a CCD cam with variable power vtx for less than $30. More details on this here for the leader.

Emax BabyHawk R for $122

Tattu 3s 450mah battery for $9

Tattu 3s 850mah battery for $12

Tattu 3s 850mah battery for $16

Leader 120 PNF 2.5" brushless quad for $110

Full Speed TX200 25/200mW VTX $10

Furibee MS Micro CCD Camera $18

HAKRC 20A 4in1 2-4s 20mm ESC $17

Whoop pro f3 light controller with OSD $18

Emax LHCP pagoda antennas (pair) $5

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 | 930 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.
http://www.rcdriver.com/6-things-you...nies-you-know/

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:

https://www.investopedia.com/terms/p/patent-troll.asp



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
