Any body useing these,I've not tryed it yet but only have ever used Futaba's 240's and good old 401's.I'm thinking about taking my 240 off my mini titan and trying it,but I've flown this little heli with NO problems at all.I'm just wondering if it's worth it or leave things alone[if it aint broke dont fix it]??

I don't know much about the gy240, but I do have a 401 and its a good gyro. I also have a JR 500t and like it alot. Its a little different to setup than the 401, but setup is pretty simple just the same. If you have any questions feel free to pick my brain. Tom

I made a mistake once, but I was wrong?

I use it. It's comparitable to the Futaba GY-401.

The setup is different. You may need to use sub-trim to get center just right, it doesn't sense neutral the way the 401 does.

Performance wise - it's a very nice gyro. Holds the tail well. I think the piro performance is a little better than the 401.

I use it on my Caliber 5 with the chinese tail weights, and the piro rate is sick. It whips the tail around so fast and stops so fast I think it could break something.

My Opinion
The g500t is a good gyro..

I have used several of them in the past...and I have tried Every single JR gyro made to date practically...lol...

The 500t works well...but occasionally I would get a fast wag that would go away with a quick collective burst...

other than that it works just like a 401...

Gain settings depend on many things...like tail blades,machine,how far out the ball is on the servo arm etc...

a good place to start on any gyro is typically 50-60% on the Gear channel for gain.

If the tail is loose...just increase...if it fast wags ...just drop a few points...

No worries if you are off a bit when you take off...

The 500t holds very well in fast backwards etc...piro flips can be a bit inconsistent and piro funnels are just not good.

If you are doing advanced stuff like this then this is not the gyro for you..

good luck though...I would fly it and be happy

A different point of view
IMO - The JR500t is a drift puppy.

JR is not known for their gyros.

If you are just learning, you may not even notice the drift.

If you are an advanced pilot, you'll need a better gyro.

If you want one?
But, I have two of these that I'm will go let go for half the cost of a new one.

They have never been crashed, pulled them off a long time ago. They just act like typical "JR" gyros.

I got rid of mine because just like a 401 the piro consistency while doing funnels and moving maneuvers is not good.

I thought it was a great gyro. I liked the way it was damped when coming to a stop from a pirouette.

Is it still available? I think everyone jumped to the 770.

Ok,I've installed it and flew it.it's not as smooth as my 401 I've had to turn the gain down to 25 to get the violent wag to stop.and at 22 it just wanders all over.So I fly it around and piro rate is out of this world, but when it stops it bounces for a while.Even in flight if I make a rudder input it bounces around.It holds well but how can I get the studder to stop,I've even jacked up the expo to 50 % and it still does it

I think you'll like it! I'm also impressed at how quick you got it setup. Some people that are used to Futaba gyros, have had fits getting a 500 to work correctly. I don't have any drift problems wag or any problems with my 500 coupled to a 9254. Although I'm no 3D pilot. Tom

Hey Tommy,what gain rate is yours set at.I started at 50 and went all the way down to 25 to stop the wag..Then two more down and it starts to hunt ,so I only have like 23 to 25 to play with And its very like glitchy,you know not smooth like the 401.Its rock solid and piro is sick but very twitchy when it moves ??

How long is your servo arm? I know that the instructions a specific with the length of it. Also what is the speed of the tail servo you are using. I myself am using like 89% with a 9254 and the longest servo arm length the gyro supports.
