My GA-250 just died during setup. The battery connector was not secured all the way, so i unplugged it again and replugged. It was on a small almost empty 2s lipo for safety reasons. It gave a little spark and now the mems chip is not responing to movements. I can still get in the gyro setup, and move the servo with the tx.....


This sux. my 401 is going back on


Meng, you want your gyro back????

Meng, do you guys have any plans of selling the gyro anywere else but hobbyking?
I bet if you could work somthing out with like xheli you could make alot more money. I know i would buy one.

Ended up with the gain at true 60%. The tail was locked in and no piro bounce.

I knew as soon as I ordered the Ino 261, I'd get it working with the ds420. *rolls eyes*

Cool!

Meng. Can you guys put a rush on HK restock so I can get the 2 I ordered???

Now we know one works my HK500GT needs one!

It's Chinese New Year, I think it is Jan 25 to Feb 15. China is shut down during that time, if it isn't in the mail, it isn't shipping for a bit

Oh crap. just yesterday ordered a copterX 250 clone on ebay. Oh well, more time to choose my electronics i guess.
Hope it wont delay my tail slider order.

Just un-vibed my tail rotor assembly and it runs quiet again. But then I just couldn't get the heli to stop spinning on the ground when spooling up.... turned out my tail was spinning the wrong way . .. what a newb mistake.

Flew 2 packs. Its holding better now as i was able to run a bit higher gain without the wag. still a little stop bounce, and a few degrees kick out with collective.

For the moment i'll leave it like this.


here's a video of today.

For the couple of times I've flown it, it works perfectly well for my style of flying. I'm just a bit concerned about some of the reported failures.

I ran the GA250 on the bench, for over an hour, before flying it. I might do the same with the Mini MEMS, but it wont help if there are vibration issues.

I might even put the second GA250 on the 500 now, especially if no failures are reported here.

I looking forward to this!

thanks, i will touch Xheli after CHY, HK maybe have no enough back up staffs like Xheli's,especially in USA. Heli flying funs need some skilled guys take advise for them, who can help them in start/install/operate etc. like gyro is not an isolate item,it's only a part and when you want it worked better, you need take care of everything.

About the Bounce.

ok, there have some reports about the GA-250's bounce.there have something need to talk openly.

First, why bounce happened in your heli? Amp give us some advice and a useful link. http://www.spartan-rc.com/resources/...&search=bounce . thanks,Amp. actually, you can got this basic knowloge in some gyros' maual papers too.

Second, if we conside simply, we can see the bounce arise is because your tail servo speed with load can't catch up your gyro's need.some guys maybe didn't agree and they will ask another question, why it's suit to 401 class gyro before and not worked in GA-250 now? the answer is simple, 401 class gyro not need such fast respond speed tail servo like GA-250's, and there have a "delay" swtich can ajust the answer speed too. GA-250 haven't such ajust setting.so, when you want use GA-250, you need a fast speed tail servo with enough tarque.

Third, why GA-250's work mode like this? that's because when we design GA-250, our target is Quark,GY520 etc. not on 401 class. we conside the pilots use it flying 3d more.for that application, the basic equipment is a fast tail servo. we forgot there have many pilots just want use GA 250 drive slow speed tail servo,because they need't want 3d flying anymore. that's our misunderstand and make a mistake.

Fourth,next step we do. our egnineers will try to impove the software to make GA-250 suit slow speed tail servos also.this one seems easy but the fact is it's too complex and no one do it before.we try.

best,

meng
