The sports frame look good, but having worked with alumi for quite some time, I can see MAJOR flaws in this design.

No offense intended. Perhaps they hope to sell many spare arms...

I hate to prove people wrong. But engineers does not give customer with false info. In pre-production simulation, the model has been optimized to have F.O.S(factor of safety) greater than 1 at 5kg impact at far end. Feel free to find out our simulation data below.

Note, at 50N impact it is not broken yet. the stress is within yield strength of 6063-t6. Therefore the arm is not stretched or bent at this point.

Actially, you pretty much supported my point with this data.

By this definition, a structure with a FOS of exactly 1 will support only the design load and no more. Any additional load will cause the structure to fail. A structure with a FOS of 2 will fail at twice the design load http://en.wikipedia.org/wiki/Factor_of_safety

A 50N impact for a quad this size fully loaded with battery and receiver is merely a mild crash from 10 feet off the ground at low speed. A high speed crash can easily generate a 300N impact with this model. That's more than 6 times more than what the frame can handle before getting mangled. Your data is based on the weight of the frame only! You seem to forget that 4 ESCs, 4 motors, wiring, a battery and a FC will be mounted to that frame.

Anyway. I'm not going to have a long debate with you about this, and if I may offer some feedback, I think 100$ + shipping for this is way over-priced. The cost of producing this frame in China is about 30$. Heck, you are charging 30$ just for replacement landing gear. It's outrageous.

Had you asked me where I think the design is flawed, I would have told you. But you seemed more concerned about "proving" me wrong.

More importantly, 6063 aluminium is roughly half as strong as 6061 T-6 aircraft aluminium and simply should NOT be used to mill multirotor arms unless you intend in making a killer selling replacement arms.

Good luck.

50N is 5kg each arm.. ... i doubt if anyone is going ot put 20kg worth of stuff on that tiny quad.

btw.. it does sound like people being jealous about the profit.

A crash never hits 4 arms at once. And 20 KG is peanuts compared to when you hit the ground at 50km/hr with a 800 gram build.

Critical, perhaps. Not jealous. They'd make more money of they sold the frames for 60$

Looks a lot like the hover things flip frame. The arms seem to be pretty thin where they attach to the center plate.

They are even thinner right in front of the motor.

Best,

Let's see the H800 folder! I will buy one...

By the way - your web site does not have much information.

just to inform anyone who is interested in Sporta that, more info and promotion can be found on the thread here
http://www.rcgroups.com/forums/showthread.php?t=2003661

MSRP of Sporta is 79.99... eHobby (us) is now offering $20 off for it. So it will be $59.99+shipping ... we are also setting up USA local shipping. It will be free shipping within USA when it is ready.
