the ga250 is ASSAN, not spartan.
the GA250 seems to work almost as well as my 3 GP750 gyros, it could be equal if it had even the basic setup functions of a GP750/GP780 gyro. For $10, I am happy with the performance and features, I would pay a bit more for expanded servo selection and a few more configuration parameters like delay, analog servo support.....

yes, i agree, GA250 is ASSAN gyro,but you can't forbid one guy compare it with Quark,another guy compare it with 401B,bal,bal...and, no body will compare 401B with Quark.

i hope meng and company can get this worked out, but to keep it ten bucks, you will have some short falls.
now, if they can produce a ten dollar gyro that works as well if not better than the more expensive ones reliably, then i will buy one.
im not trying to discourage them from developments. just saying that no matter what, someone will not be happy.
I guess I haven't kept up with the thead, do you actually have one of these?

nope,
i was responding to how people want this to be a spartan straight out the gate.
i was trying to defend meng, and show how no matter what, theres always someone thats never happy.
im saying,
if I paid ten bucks, and it worked? im happy. but if I paid 200 bucks, i would expect performance.
does this make sense? not knocking meng or his intentions.

that is correct, i've seen people complain that their quark and hyperion ds11 is not performing up to par, so they ended up buying a futaba gyro that worked well for them. I'm sure spartan will learn from it, may be they will try to make their gyro more user friendly? Who knows, that's part of progress. As for this gyro being $10 i think it's a bang for buck. Especially the way the worlds financial economy is going, people in america losing their jobs and can't afford a pricey heli or pricey gyro/servo, this GA250 definately opens up door for those people. As long as this hobby continues on growing, then it is good. So to those people buy yourself a clone, buy yourself this cheap ga250 gyro, and get it out there and fly.

well, you should read through the thread, it is an impressive gyro and ASSAN has specifically asked our inputs. To that end we have been feeding back to Meng and he has been passing it on to their engineers. Please don't help anymore, I really want then to implement delay and analog servo support. Lots of other functions like piro optimize and stop gains would make this a more Quark like, if ASSAN can implement it, that is awesome, but I am not asking for that.

Honestly, your position does not make allot of sense to me. Sorry dawg, I completely disagree with you in spite of your help. I suggest you order one and try it out or....stop helping no offense intended

never mind,

i`ll look back in on this adventure in a year, if meng ends up producing a gyro that can perform as good in analog as one does in digital, i`ll buy one for ten bucks.
i dont see this happening really, simply because if it could have been that easy, we wouldnt have digital gyros and servos.

i wonder how many of the top event winning pilots run the old mechanical gyros?

lol. I don't know someone here(in this forum) once said it doesn't matter if you have the state of the art heli and the most expensive setup. It doesn't make you fly any better.

Most people say to fly with CF blades, because they perform better, but i've seen bert k fly with plastics blades just as good if not better with CF blades. go figure.

On A Happier Note. . .

Meng,

On my initial 500HK build I used a Turnigy Mini MEMS gyro coupled w/ a Hyperion Atlas DS20x-GCD tail servo. That gyro caused a tail jitter that no amount of programming would resolve. I changed tail servos, bearings, tail rotor shafts, tail rotor blades, did everything conceivable to reduce vibration, raised the dead-band on the Hyperion Atlas (programmable servo), changed ball link distance from center of control arm, raised & lowered gyro gain on the Tx: Nothing relieved the violent, short coupled tail shake. Four months I have spent researching, following advice given, all ending in frustration.

Then I switched to the ASSAN GA-250. I received mine on March 14, latest batch HK got apparently because I was on back order, they sold out shortly after filling my order and they havenít re-stocked again.

After deciphering the instruction manual and setting up the gyro I took it up for a spin: Rock solid tail, even on pitch pumps, fierce piro rate, dead bang piro stop, left or right w/ no bounce whatsoever.

Needless to say, no tail jitter.

Great gyro.

Jules

Alright, nobody asked for a analog servo to perform like (or better) then a digital servo. The GA-250 only works with digital servos, and not all digital servos, I want it to work with all servos. It's that simple.

I think that a lot of the issues of this gyro are only seen on the incredibly fussy T-Rex 250 and clones. For other helis it seems much better behaved. Unfortunately for Meng and ASSAN they've named it the 250, and its size lends itself very well for installing on a 250 sized helicopter.

I think people are also getting lost in semantics too. It doesn't really matter what people think about the gyro or what comparisons they make. If Assan can make it user-programmable thru a USB interface to a pc, then savvy users can extract the most from it, whilst less sophisticated users can just run it as it comes out of the box. Surely that leaves everyone happy. My reading of Meng's comments suggests that getting it to work at analog servo frequencies is just a firmware rather than hardware matter.

Couldn't agree more with what people are saying, if ASSAN can get it to work well on small helis and with less expensive servos, and with PC programming then FANTASTIC !!. I don't care if they are not upgradeable to the latest firmware - for $10 I will happily buy new versions !!!

+1. I have 4 (2 from the first batch and 2 from the second batch). Can't wait for the next release, to buy a couple more.
