I've got you both beat! Here's mine and it's only 300ish grams! Hah!

Cheater...that's not full AUW weight. Let us know when you're ready to compare to the big boys!!!!

About to get started on mine, I got the arms together last night. Have my VC450 tuned pretty solid with the CC, so I will leave it together and fly it/ (Crash it), while I put this one together and tune its CC. Weather is finally starting the get nice here, now if my work would cooperate............

Thanks. At first I thought I would be safe with a 12 amp esc, as you measured max average of 8amp/motor. But then I realized that in flight, one motor will always be pulling more amps than the other. So the average may be 8a, but the peak of one motor could be much higher....

Yeah, just to clarify. An ESC is just a switching device that turns on and off. When on it's passing current through the motor. When off no current to the motor. Of course it switches on and off very fast...the longer the duty cycle (on longer than off) the more current is shown. For example: if always on the max amps are 12A. When at half throttle (on half the time, off half the time) the shown amps may only be 6A, but the actual amps passed are still 12A while the ESC is switched on. So...amps are a measurement of current over a given period of time. An 10A esc would not be good on a power system pulling 12A max...even if you only fly at a half throttle draw of 6A as the system is still drawing the full 12A when on.

As for in flight...unless you're doing some aerobatics (flips/rolls/etc) I don't think the current draw from one motor to another will be a large difference. If the absolute max amps a motor/prop combination draws is 8 amps then a 12A ESC should be fine. My motor tests where actual flight tests. I probably never hit full throttle during the flights...probably close to 3/4 +/- throttle stick for the majority of 'high' throttle maneuvers...so take add a couple of amps to my max readings to be on the safe side of MAX draw per motor.

We just listed them on the website, but people are buying them as soon as fast as we list them. We will be adding them almost every day, so be sure to click the link "notify me when the product is available".. We have 25 frames here but we are waiting on aluminum spacers before we can put them into inventory, so probably tomorrow.

I will be cutting more tonight as well.

Everything was neatly packaged, but just was short a few pieces.

I've also struggled a bit to get the legs to "snap" into place. I'm afraid to put too much pressure on it for fear of busting it and having to wait for replacement parts. I don't want to trim it to make it go easier as I want it snug, but man, it is tight...

WHOOPS!!

Glad you guys noticed the spacer count. I must have counted before I added the spacers for the rubber grommets.

Will correct that in the kit. Sorry about that.

Also, regarding them arms snapping in... don't worry you are not going to break it. You WILL have to flex the center plate while pressing the arms into place firmly the first time. You will hear a loud CLICK as they snap in. This is ok... because after you fly it for awhile the G10 will wear and the edges will compress and the arms will fit perfectly. Not all of them will be this hard to get in, but better a bit tight than loose with this design.

Regarding those with weird flying issues, remember your pitch and roll gains will be slightly different.. this quad is wider than it is long.

Also, if you are having strange issues, make sure your ESC's are all grounded together at the signal leads... some esc's work fine with just signal, but other require both signal and ground to work correctly.

Also, enable autolevel for the first few flights... this will help you get flying and you can get an idea if it's a motor/esc issue or just a gains issue.

Don't make this mistake by being too excited about getting your frame built.

Top plate is on there good but darn…..I forgot the arms!!

I love this frame but I sure wish the arms were Auto Attaching

The only odd snafu during the build was that I shaved one of the arm tabs 1mm to short and it doesn't snap into its socket snugly.

Either way, vibes are the only culprit left at this point so off I go.

I have the same issue, no idea yet. Completely reset all my settings on CC, thing just wants to pitch and go forward. I feel its pretty balanced according to the CG line.

mine is 1405 grams, OSD, GPS, 3000 mAh, and a 370 mAh for camera

Maybe folks can post some screenshots of the Copter Control Stabilization panel. Since we all have the same frame and similar parts it would probably help some of us. I'm just flying in Altitude mode and I can't get it from pitching forward. I'm playing with the AccelBias setting since I just reset the board completely.

shdwkeeper,

I'm a newby so consider the source and bee easy on me if you've done all this already :<)

This may have nothing to do with your problem, and I know nothing about OP CC boards, but this is how I cured a similar problem with my advanced zoom MW 1.9

1. Set radio trims to neutral
2. Run through the pre-flight calibrations
3. Attempt to hover in ACCRO and take note which way it wants to go
4. Land if you need to and course adjust with transmitter trims... repeat as necessary
5. Make fine adjustments with "beat sticking" method and proceed to ATTI mode and enjoy hovering hands free...

Remember, I'm a newby so go easy on me if I'm completely off base.

I'm just as new as you I probably need to just reset my transmitter and start over, all trims are neutral though

In other news, I am still having major issues getting my FPV frame to fly. Seems like no matter which combination of gear I install it flies very squirrely and loose, wanting to yaw and pitch back the whole time.

You didn't mention what your gain settings are, also do you have a camera installed?

On my Naza I am running gains at 200%, and 250% for vertical gain.

Flies fine in both autolevel mode and manual mode.

Without camera installed it will fly weird. It is designed to balance with camera. If it's trying to fly backwards you should slide battery forward or add weight up front... you may be using a battery which is too heavy to balance near correct CG.

I actually put my Naza on the frame today and it flies much much better. With default pids manual is fine and it holds the altitude without any problems. There's no drift up or down. It's just a little touchy with 1400kv motors, I've noticed Naza works best with motors around 900-1100kv. 1400kv almost makes it want to take off. Hitting failsafe actually made it take off before it adjusted itself to the new motors. (Don't ask me how, it just did, after a few short circuits in ATTI mode it seems like the failsafe rpm changed and it now slowly drops to the ground when failsafe is engaged, like it should.)

Yaw is a little weird, I'm gonna tinker with the yaw gains tomorrow. Ah, that thing about signal + ground, good to know. I've got signal wires only hooked up to my Naza, I'll reconnect the ground wires tomorrow.
