Micro quad before crashing











It's the most energetic platform so far, definitely not a toy. Those Turnigy 1811-2900's get a lot more thrust from the same space as brushed motors.


The Chinese must find it at least amusing to be presented a brand new aircraft every 3 months, with a brand new design, attempting to do exactly the same thing. They're the only capitalists in the world, but they inherited the soviet tradition of requiring every step to be a complete flying system rather than a unit test. They won't accept qualifying a navigation system as a milestone. Every single demo has to be a finished product.


So 99% of your time is spent designing a new airframe, debugging the PWM, debugging the communication, debugging the ground station, press fitting the props, calibrating new PID constants, just to make a single incremental improvement in the navigation system that isn't viable in the final product. It's a ridiculously inefficient way to make progress & might be why the Chinese are always accused of copying rather than inventing. You can't invent anything without unit tests.



The soviet union did this with the N1. To test the engines, they had to build & fly a completely new rocket. They couldn't test the engines separately, so they crashed 3 rockets & ran out of money before the engines worked.


A lot more could have been accomplished if the milestone was the navigation system rather than building a completely new flying system every 3 months. You already know the requirements for the navigation system without building a new vehicle for every unit test.

But China is the only game in town, making their system the world's system. Americans can't even pronounce calculus, let alone afford a pot to piss in.


Every day, China receives thousands of proposals from inventors in the western economies which simply aren't sustaining their people. They're all insanely great inventions. It's very hard for any invention to stand out. Some of them are from Mark Tilden & Lonnie Johnson, ideas so off the scale, they get immediate funding & become instant commercial successes. Others keep trying forever, at least giving the Chinese a good laugh.

Could be due to low cost of production in China, coupled with China not having any sort of copyright law. How do you think they can get away with selling things like, dongles that work with 6 different simulators and include the simulator software as you would purchase it from Phoenix, Real Flight, etc. This doesn't even get into the fact of them producing an F-22 the J-20 is a direct rip off of the F-22 down to rivet locations. Couple this with the fact that no US government body is allowed to use Chinese made computers or parts due to espionage concerns, it's easy to see why.

When your country produces the worlds goods cheaply it's no wonder why the rest of the world brings their goods in to be manufactured, the crux is that everything they make they copy and release their own, most times prior to or at the same time the originals are released.
