Is the 401 enough gyro?

[cd5]

I am tuning my 600n and the tail is a little inconsistent. there could be 2 reasons for this and i was wondering if my thoughts were founded,
I have a bit of a twitch(very slight but noticeable) in the tail and its not gain, could it be from the gyro being mounted above the aileron servos on the mounting plate, has anyone found this to be a bad mount place.
The piro rate is somewhat inconsistent also. My 450 and 500 perform flawlessly , so i am beginning to think the 401 might be a little bit suited to the smaller helis .
Do you think the 600n is more worthy of a higher end gyro, or is the 401 more than enough and i just might be glitching from the servo proximity.
Also what benefits are their to be had by the higher end gyros?
Thanx

The 401 does seem to sufer more than other gyros when fitted above the servos, I've seen one where the tail kicked everytime a cyclic input was given. Tail kicks sould also be due to the engine not being quite in-tune and 'coughing' occasionally.

First off I'd try relocating the gyro to see if you get any improvement, if not check engine tune. The piro rate on the 401 can be uneven, especially when there's some wind about plus it can blow out in fast backward flight, if you're hitting these sorts of problems then a better gyro would the best bet. I've had very good results with CSM720 and JR 770 gyros and if you search the forum you'll also find recommendations for the Futaba 611, Solid G and Spartan DS760 gyros.

Don't forget the Logictech 6100T...some say it's better than the 611 with which it competes..and about 50 bucks cheaper. I use it, it's solid as a brick wall.

Some also say that the JR G770 gyro is as good as or better than the 611 and it costs only slightly more than a 401. I have no complaints at all about my G770/8900G combo.

I have my 401 on my Nitro Sport mounted on the rear, on the tail casing. I had to relocate it farther back as I was getting kick from having it too close to that top bearing though. You might need to adjust gain, or remount the gyro and try again. My 2cents is the 401 is plenty good enough for the 600 until you get into very advanced maneuvers(which I'm nowhere near now). I'm buying JR G770's now b/c they aren't much more and are supposed to rock hard. I'll see, as one is going in my present 600N pro build :).

Hi CD5,

Yes, the 600 is worthy of a premium gyro. I had a 401 and it didn't take long for me to realize that it was a sub-par gyro. First off, it has a very inconsistent pirouette rate. I like to do slow pirouettes as part of my routine and the 401 makes it very difficult. Secondly, it doesn't always hold in repetitive flips or fast backwards flight. There are so many good gyros on the market, that there is no reason to fly with a marginal product.

I went to the JR 770. It's a bit better. It holds great. But it's difficult to set up. And mine drifted requiring some trim. And there are no separate right and left adjustments. But the thing I like least about it are the very hard stops. They are so hard that I can hear the belt snapping when doing 540 stall turns.

Then I went to the 611. What a treat. They hold great and are fully configurable. There are left and right travel adjustments and delay settings that soften the stops. I truly feel spoiled when I am flying these gems.

But, if I had to do it over again, I would get the Spartan DS760. It has all the features of the 611 but in a much smaller package. The 611, with it's separate amplifier, is heavier, and susceptible to crash damage. Plus you have to find room to place the amp. With the DS760, you just hook up your laptop to configure the gyro.

Anyway, that's my $.02. Take it for what it's worth. A lot of guys have different preferences. But the top guys where I fly are moving from the 611s to the DS760s.

Keep 'em flying.:YeaBaby:

Is the servo horn supposed to jitter at all, cause I play with the sensitivity and cant completly get rid of that jitter on the bench?
