As you may know a couple brands have now released 3D quadcopters. For example the Invertix 400 by Encore RC, and the Align Leap 3D Quad. Even the Blade 200QX has been converted to a 3D quad by Blade.
I just think these things are great.
The Stingray 500 by Curtis Youngblood is a 3D quad but its pretty complicated and doesn't crash well, as well as being about $800 to build. They use variable pitch rotors, as well as a single motor (with belt drives to each motor) and a special flight controller to control it. (TG-Multi)
Quads like the Invertix and Leap 3D, they are a bit different. They use fully symmetrical propellers, powerful motors, and... wait for it.... reversible ESC's. The SimonK has been perfecting reversible firmware for several years now, there is a huge thread on RCGroups about it. Basically, from 0-50% throttle is negative throttle, and 50-100% is positive throttle. The load on the ESC and motor during the reversal is pretty intense which is why you must have very powerful motors and ESC's bigger than you normally would have, otherwise it goes poof and releases the magic smoke.
These are just the coolest thing to me (after helicopters )
So I decided to build one myself.
Thanks to many helpful people on RCGroups and HeliFreak I have come up with a good setup for a powerful 3D quadcopter.
I'm going with
SunnySky X2212-9 1400KV Motors
RTFQuads 30A RapidESC Flashed with Reversible Firmware
HQProp 8x4.5 Symmetrical 3D Props
Zippy 1800mAh 4s 40C LiPo
Flip 1.5 with 3D Firmware
1400Kv may seem very high for 4s, but because the props are symmetrical they are super inefficient, they must turn much faster to achieve the same thrust output compared to a normal prop. 1800mAh may seem small but we are trying to keep the weight down here.
I'm going with the $10 F330 frame from HobbyKing. I actually bought two in case I break one because they are so cheap and the perfect size.
This thing is gonna be a rocket
However, I also enjoy FPV and AV.
I also bought some other stuff. In an attempt to make this quad capable of FPV and long flight times, I also bought some 9x4.7 SF propellers, a 3s 5000mAh (!!!!) battery, and a 5.8GHz 200mw (not very powerful I know but it was on sale for $50 at FoxtechFPV) FPV system. I plan on using my GoPro for FPV. I also got an adapter that would plug directly into the GoPro and to the FPV transmitter that would eliminate long cables and adapters. The adapter has a power lead so you can plug it into the FC to 5v and charge your GoPro while you fly. Pretty neat
Here's a video to keep you waiting
