Should I be concerned?

Had great success with my first build today. The Naza M Lite allowed me a successful dance, recognized sufficient satelites, and seemed agreeable to an airborne adventure. With no props on the motors, I moved the sticks to extremes, the motors armed, and I was in control! WOO HOO!! Curiously, with just a wee bit of throttle, 2 motors spin. A bit more stick, another spins, and with more all 4 are finally spinning. When all were spinning, I could register fluctuations in the rpms as I alter the pitch and aileron. With the right stick in center position, it seems that the 4 motors would spin up at approx. the same speed. Should I be concerned about this?

As long as your escs are calibrated it should be fine.

I always do the v2 hack on mine.

"As long as your escs are calibrated it should be fine."

Yeah, about that. In all my set up procedures, I've never yet found an option or utility to calibrate the escs. In a nutshell, this is what I've put together so far:

Alien Bee carbon fiber frame
Naza M lite w/gps
JRelics A2212/13T motors (1000KV) w/10X4.5 props and 30 amp escs
Turnigy 2200 3S batt.
Flysky FS-i6 Tx w/ FS-IA6 Rx

so far. FPV gear will come soon.

This morning I couldn't help myself, no self restraint at all. I just had to mount the props and take it outside for a quick hover test. It seemed a little squirrely, but it did hover, yaw pitch and roll all functioned as expected. I was elated. Now I know I've got a mechanically functioning quad, so now I need to tackle some programming issues. The squirrely flight may have been only because I still had the mode switch in manual, not atti. or GPS.

I checked out the information on the link you provided for the V2 upgrade. Did you have much trouble dld'ing and installing it? I wish I were just a bit more confident about the computer end of this process. I wonder if the version 2 would help with the failsafe issue I'm having.

The FS-i6 Tx has only 1, 3 position switch. Switch C. In order to ask my bird for a dance, I HAVE to have my flight control function programmed to Switch C. Currently I have it set up with end points and sub-trim so that full up (pos. 1) puts the Naza in Manual, position 2 puts it in Atti. mode, and full down or position 3 puts it into GPS mode. I was able to get Switch A programmed (by using the "mix" feature) so that when I switch it down, or off, then the Rx will go into failsafe, but ONLY if the flight mode switch is in the manual position. And when I turn the Tx off, the Rx fails to go into failsafe. I have the IOC turned off, it also requires a 3 pos. switch, and I've only one. This is the best I've been able to get so far, and it's still unacceptable. If the bird got out of range, it'd fail to go into failsafe.

Do you think that any of the features of the Naza V2 will help me with this predicament?

Thanks in advance for any opinions

Sweet!

The upgrade will make the aircraft more stable, and provide more features, but you will have to purchase a v2 pmu to use most of them.

You may have to adjust the gains to your aircraft. Basic are for environment, and atti for stick input.

And when I turn the Tx off, the Rx fails to go into failsafe.

You've gone the the i6's menu and activated failsafes? Have you tried setting let's say Throttle to a large minus number? If you aren't using SWD go into the menu and enable Throttle hold, Up is ON (just normal) , pull DN and set it 0%. That's sweet to have either way, becomes an on/off motor switch. I've gotten in the habit of keeping it down when I'm futzing around (not flying) and still plugged in.

I'm a tad confused are all 6ch of the TX now being used? By failsafe do you mean return to launch?

Right, in the i6 menu, failsafe is supposed to rise if necessary, return to home coordinates, and land. Especially when accidentally flown out of range, or Tx gets turned off, the bird is SUPPOSED to just come home. (in a perfect world, I guess) Now, I did have the throttle hold set on Sw C for a while, but I do like your idea. I'll set it back up with a value of 0%. I can see how that would be very handy for safetys sake. As I write this, the adrenalin is still flowing. I just took her out, remembered to switch to GPS mode, and flew for about 4 0r 5 minutes. Let her go up 50 t0 100', she hovered beautifully during a 360 yaw rotation, descended, rotated, ascended again, rapid descent, immediate response to throttle. It was coming down quickly, but slowed to a hover just a foot off the ground, then very gently landed on uneven ground. It was something to see. I am so psyched. I stuck a RunCam on the front of her for this test. I used foam mounting tape, got some nice video of the flight, but also a lot of vibration. I'll have to check those props again, and come up with a better mount for that little cam.
