Default t-600 gyro?

I found an align gp750 open box gyro that i can get from a hobby shop online for 89 bucks plus shipping and I wanted to know if it would work as a good gyro for my trex 600 build? and also I wanted to know what parts I should have on hand and what parts usually break in a crash. please let me know what you guys think thanks.

Here's my .02.

I haven't put a GP750 on a 600 but I did put one on a 250 I had for a short time and it seemed to work pretty good for the short time I had it.
When I bought my first Trex600 it came with the GP780 and I could not get the tail to stop wagging and I tried all the tricks and suggestions. I had a 780 on a Trex500 and after a little tweaking with gain settings and servo arm locations I was able to get rid of about 98% of the tail wag.
After reading a lot on here about people not being able to get the tail on their 600 to stop wagging with the GP780, I bought a used Spartan DS760, mounted it, went through the setup (very easy BTW) and no more tail wag.
When I bought the second 600, it too came with a GP780. Although it was new and had nevr been powered up I never even tried it. I just bought another DS760, mounted it and the tail is rock solid.

So my vote would be for either a DS760 or Quark, they seem to work the best. You can pick them used for about the same price as what your LHS is charging for the 750. In fact mannypr24 has one for sale now. He's the person I bought my first one from.

Fortunatly I haven't been down the crash road yet so I can't really say but I have been slowly collecting parts. So far I have the following,
  1. Main Shaft
  2. Feathering shaft
  3. Tail Booms
  4. Torque Tube
  5. Torque Tube gears
  6. Main gear
  7. Auto gear
  8. Landing gear struts
I'm sure some others who have been through a crash or two will chime in.

My 600ESP has a GP750 and a DS620, and the tail is pretty well behaved. I would love to try different gyros though, like a Spartan and a GY520 but what I have currently is better than my flying ability.

My next heli will probably be FBL, so I may never get to try different gyros.

I would suggest the GY520, the Spartan 760, or the Quark.

I found the GY520 to be much easier than the Spartan to set up. The GY520 and the Quark are similar to program (IMHO-both very easy and easier than the Spartan).

Of the three, I think the GY520 is the best performing (I have all three).

I can't speak for how the GP750 compares to other gyros, but it is very simple to setup.

I have no experience with the Align gyros. I prefer the Futaba or Spartan/Quarks for stand alone gyros, V-Bar and BeastX for FBL set-ups.

I am not sure what people are doing wrong, but I have the 780 and the 520. When I first had my 520 it was a total nightmare for me to set up, and fine tune to get it to be rock solid. Once I found it, it was really easy. I have found that the 780 is the same way (sadly). I can say this the 780 gyro does not take much gain, (it takes less then the 520). Plus this gyro is crazy picky, when it comes to smoothness. If the tail pitch slider binds ever so slightly it will wag. If the temp is off hot or cold, it will wag, however when I do normal maintenance my 780 holds well. At times it will wag very little if I come down really fast, but for the most part it is rock solid. Electronics now a days, are so darn demanding. sheesh

I had the 750 on my 600 for almost a year with no probs. Maybe I got a good one.
I then got a 780 with the next heli and again no probs. Now have 3g and still rock solid.

GY520 w/Futaba 9254 on elderly Trex 600E:


Geezer type flying but you can see that the tail holds very well.

The machine is, of course, equipped with KBDD Paddles, Dampers, and Tail Blades!

Yes, I am older than dirt...

Most of the guys I fly with are much younger and fly hard 3D, I am old and slow and so is my flying...
