Think I'll wait for the early adopters to identify the issues first. That motor looks like a mosfet killer.

Then you see that other companies can discover the same idea, and be one better than you. The problem is you can't change the configuration without starting with a new model. Then you know the customers would be pissed at you for changing again. Sometimes management are piss at you for making more changes. Eventually, you have to do it.

I think this helicopter will be inherently better than the Genius, and there is no other way to get then than a new design. This has a lower polar moment of inertia. Circuit board is vertical, and close to the mast for less polar inertia.
Looks like servos are positioned almost radially around the mast in a 120 deg configuration. The cg of the servos looks very close to the mast. That is more efficient for low polar inertia not haveing the long length of the servo in a rectangular configuration like the current Genius. The battery is directly under the mast. That is also lower inertia than having the battery stick out front.
Just base on physics alone, the 3D capability should be better than the Genius all else being equal. Should be able to flip and yaw faster. The Genius cannot be "tweeked" for this type of improvement. Is a new configuration. When they say is smaller than the Genius, I don't think is actuallly any smaller rotor wise, but is probably the mechanism that is more compact.

I'd like to see if they can still repeatedly stomp on the Canopy, and Landing Skids again though.

I'd be even happier, if they also showed the Tail Boom and Main Frame survive being stomped on!

If they could manufacture it to survive that kind of abuse, then they'd probably have to legally put Warning labels on it, cautioning not to put it in our mouth, just to be on the "safe" side.
To get closest to Main Shaft, mount the RX under Main Gear.

Position center of RX (just like Battery) under Main Shaft CoG.

That would give it the Best Piro Rate.

Right?

Problem, how to balance the Tail? Answer: Go back to prior design

Looks quite durable. 3:36...
I've seen the V120D02S crashed onto pavement repeatedly in videos with no damage and yet in every crash onto pavement that I've had happen I stripped a servo.

If they sell that module with the new faceplate I will consider buying it.

The current Genius does use Fairchild PowerTrench MOSFET which is one of the best out there. Walkera is starting to use top quality components here. So it might be ok.

They can't screw up too bad on this one. All the components except for the motor has already been proven. The only unknown is the circuit board, but you can download software now, so that should eliminate the risk of program error. Given Genius's track record, would say this is relatively risk free for early adopters.

That got me thinking about the ultimate set-up. They can use a shaft drive with tiny bevel gears to save weight back there.
For tail control, at this scale, servo is too big and clumsy. A voice coil fits the application better. That is the same kind of actuator on the read/write arm of a hard drive. If the blades are balanced properly with "chinese weights", should theoretically take no force to change the pitch. Voice coil can be ultra fast. Then don't even use a pot for position feedback. That adds too much complication. Use the yaw of the helicopter via gyro as the feedback.

There you have it, light, perfect tail control. That would be very fun helicopter! Hope Walkera is listening.

The official specs are now out on Walkera's site

http://www.walkera.com/en1/particular.jsp?pn=MiniCP



This heli will be compatible with the Devo 6,7,8, and 12 in addition to the 8S. There will also be a BNF version available for the 2801 pro. One of the most important new features is that the firmware of the receiver can be upgraded through the Internet. Perhaps we are now getting close to the day when we have a full blown FBL system like the BeastX and 3GX in a micro heli.

What started as a little money sucker with the Genius is about to turn into a gigantic vacuum cleaner for your money!

+1. I started flying over grass exclusively! Just gotta watch those tail gears!

The rx upgrade port will probably use some proprietary connector only compatible with the Devo 8s.

You can have my membership card for the one heli a month club. So you can now be in the two helis a month club.

But I haven't even ordered a single heli this month or for that matter this year,,,,,,yet.. So if I plan this right I'll send in the order at 11:59PM on 1/31/12 and one will end up being the January one and the other the February one..
