Well I need to know something like how much % gain should be applied for SD & HH mode. I use 85% in both mode.

All's well that ends well

I can get to 60% on my 2100, after that I get tail wag.
Basically you want to run as high as you can without the tail wagging.
It's a trial and error thing.

Merlin1205,
Do u use 60% on both HH & SD mode? I use 85% on both mode.Problem is trying to get same effect in both mode. Do u use trim or subtrim for any mode?Don't know weather poeple use remote both mode remotely from TX.

All's well that ends well

first off,you will never get the same effect in RATE and HH,they operate differently.no matter how well you set up a RATE gyro it will NEVER hold like HH,on a 2100 you should only use RATE when setting up the tail,or if you are flying scale and like the tail to be a little loose(looks more natural),Also on a 2100 NEVER repeat NEVER use trim or subtrim(ch4) in any mode.PERIOD.You set it up in rate using the linkage or moving the servo on the boom,the 2100 is really sensitive to this so you must set it up properly in rate for it to hold well in HH.One more thing that often gets overlooked on a 2100 make sure the gyro is showing the same gain that the TX is,if not you need to adjust the endpoints of the channel(if applicable) your gain wire is plugged into.This makes a big difference in performance on the 2100

With the Dx7, Gain plugged into Gear channel, Today I was doing some reconfigurations on the 2100t and I have HeadHolding set at 50% ATV, give or take 1% or 1.3% difference in values from the transmitter and the value that shows on the gyro. Any higher than 50% I start getting a wag and it gets more violent as you go up.

getting the gyro matched up with the TX has nothing to do with performance of the gyro at all lol rudder atv should be at 150 both ways as this gyro can have a slow piro rate as it is let alone slowing it down. and its easier to set up this gyro with a dx7 using the gear channel atv to adjust gain instead of going through the gyro channel. [it can be done but its a pain, and if so you cant match up gain ever]

mechanical trimming with no subtrim is however correct and a must.

it most certailty does,I have helped set up gyros where the pilot was getting wag at a low gain ....the reason was the gyro was showing almost 90% gain when the tx was showing only 65%....so while the pilot thought he was at 65 he was REALLY at 90,which caused the wag...it also works the other way around if the tx is showing 85 and the gyro is reading 30% pilots wonder why thier gain is set at 90 and the tail wont hold...its because the gyro is only seeing 30-40%,When they are matched up you know the gyro is seeing exactly what the tx is showing,eliminating any discrepencies as causes for wag/not holding

also how do you guys know he is using a dx7?I read this post and his profile and didn't see anything,thats why I wrote "where applicable"about the gain ch as I cant find any reference to radio

not trying to bust your b@lls bud but your missing the point.

you said for added performance you need to match TX to gyro.[commonly overlooked] its not true in any aspect.

im saying on a dx7 you cant match unless your in gear channel, dont really know what TX you had but allot of us do.

i understand what you were saying, and no where do you point out how performance is gained matching TX to gyro. you did indicate that someone did not know how to properly tune the gyro and only read the TX when in fact on this gyro you look at the led lights. thats plain old user error not a gain in performance. . gyro gain is controled through the TX and read by the gyro. just because the numbers dont match does not mean on mine or anyone else,s that there heli will fly worse. the gyro cannot tell what numbers your TX has in it. it just picks up the signal and translates it to the proper input required.

it does say in the manual if you want you can match them for convienence you can if you even choose to do so, but for performance it means absolutly nothing.

i run 2 of these and ive had them for a long time 1 on a V2 trex 450 and 1 on a trex 500. both mine have tails that are rock solid even in inverted reverses FF stalls and loops piros ect. the gyro is top shelf stuff when tuned properly. if anything im just trying to teach you proper use of your gyro. my numbers have never matched and you cant tune an once of performance into it by matching TX to gyro. understand

all I was trying to point out to him is make sure the numbers are in the ballpark,as it seems he is not familiar with the equipment,as per some of his questions and statements

I was merely trying to say that I have seen guys say they are having problems with this gyro,and the solution to the problem was that they were not paying attention to the actual gain on the gyro,they were completely concerned with what the tx says,what the TX says means nothing,really,its what the gyro is showing that matters,,as I said earlier for example the tx could be showing 80% but if the gyro is reading 30% in HH the tail may not hold so well,if you check that the numbers are atleast close,then you can rule that out as a problem......I have seen quite a few people complain about tail wag at low gain settings with the 2100 only to find that the actual gain of the gyro was higher than what the tx showed

basically I'm saying set up= performance,crappy set up= crappy performance,ok set up =ok performance,great set up= great performance,so the better more precise and fine tuned the set up is,the better the performance.......if you put the gyro in RATE for mechanical set up(say 30% as in the manual) and the first led is on,it could be 2% gain or 29% gain,but if you know the tx/gyro are close,you know exactly what you are dealing with

Guys,
I actually wanted to know very simple thing other than going into off relavant stuff,,,
I use 2100T gyro
DX6 radio
Did all the mechanical adjustment as possible to get the best perfomance both in HH & SD mode.
Gyro gain is 85% in both mode.
Now the problem is to get the best performance I have to use rudder trim +4 in SD & -4 in HH. I want keeping 0% in both mode but no way I could make it. If I do mechanical adjustment in SD keeping the rudder trim 0% then HD also has to be change ,,,say probably more than 4%.
Problem is in two mode,rudder trim 0% the tail doesn't stay very straight.I have to use a little rudder trim to keep the tail exact straight. I don't know I could make u understand my problem as I'm not elglish spoken man.

All's well that ends well
