Lrrps,
I guess you already found out it is called ATL on your radio.
I use it to stop binding at the end of servo throw. I normally do not have a throw issue though.
Or, it can be used to set caps on things like the pitch but there are better ways like with the pitch curve. And the swash settings are sorta like setting a pitch curve for cyclic response.
And even for the tail servo I use the limit pot on the servo if I have binding. For one if you used the ATL on the tail you would be affecting the sensitivity setting.
So I normally have them at 100 and use other methods to adjust the throw.

Dan. Channel mapping for G3
channel 1 = roll
channel 2 = pitch
channel 3 = throttle
channel 4 = yaw
channel 5 = D/R
channel 6 = 3 pos switch
On channel 5 and 6 you have to move the according switch on you radio and see on the scale whats moving then set it from the pull down choices. You might have to reverse a channel by checking the box next to the coresponding channel. It was a ***** to figure out and it might not work the same for your TX. I was using my optic 6 TX with these ettings but now I just use my G3 controller.....Hope that helps.

RE: Official T-rex 450 XL SE Thread
Ok thanks. That helped alot! WEll my brother wanted to make a remote start for his little car, and now hes makin it brushless, so i sold him the raido. Im off tomorrow to buy a ccpm radio (problay the biggest factor) with more swiches and knobs and other crap like that. I could never get it to work with the old radio.
Thanks
Dan
Thanks

RE: Official T-rex 450 XL SE Thread
JD,
I actually did have binding at my tail servo. So i set the rudder servo limit to 32,32. What other methods do you recommend to use if i dont want to reduce the limit on the Tx? Sorry i'm still new to these things and always need help from all the seniors here.
By the way, i can feel that i actually improved alot after i got my trex. Even when i try hovering with my 22E, i can control it better. Unlike last time where i am having a hard time just trying to calm it down for a stable hover.

What gyro are you using? Travel is edjusted through the limiting pot on the 401. Piro speed is controlled by end point. If you try to set travel through the tx you'll just mess things up with the 401.

Shadowin, set your rudder end points back to 100%, power up in HH, then swich to rate mode. Check your tail throw for binding left/right and reduce the limit setting on the 401 until you don't get any binding. You can then move your servo on the boom to better center throws if it was binding on one side, slowly raise the limit setting until you see that your getting max throw in both dirrections.

Okay, i set back my rudder end points to 100%. Then tried lowering the limit settings on the 401. I still get binding even after i set the limit to the lowest of 60?

RE: Official T-rex 450 XL SE Thread
Is it only to one side? Are you using the disk for a servo horn
If it's both sides, your going to need to move the ball at the servo horn closer to the servo's shaft.

I have already set the servo on the center. So it's binding on both sides. And yes, I'm using the disc for a servo horn. Is this bad?

No, I'm also using the disk with the stock hole.
I don't know why your getting binding, as my limit is set up to about 80.

RE: Official T-rex 450 XL SE Thread
Yeah i notice the difference once i set back my end points to 100%. The pitch change faster when i give rudder input on the Tx. Never mind, maybe i will ask my friends when i meet up with them this weekend. Thanx for your advice.

RE: Official T-rex 450 XL SE Thread
sorry guys, but that's incorrect. The piro rate, is set with the ATV on the tx. shadowin, you might have to drill a hole in the disc closer to the servo, so its not moving the rod so much. Trust me, you MUST set throw to eliminate binding with the limit pot. THEN go in and increase your ATVs (end point adjustments) and watch your piro rate really speed up. Guys, everyone's limit pot will be set differently because we all have different linkage geometry. I agree with cflight that you set center in rate mode, but the binding and piro rate is done properly as I have outlined.

Guys,
Do you know that a triple blade head is available for the Trex 450?
Look here: http://flying-hobby.com/catalog/prod...0308ea7f4d6af4
Wonder what difference it makes and what improvement over the normal twin blade head.

ATV= adjust travel value EPA= end point adjustment , these are both the same as travel adjust, different radio brands just use diff. terms.
In regards to three or four blade head, they're used for scale builds, requiring weight added to shortened blades at the tips, and in most cases a mixer accompanied by two gyros for cyclic control of the rotor disk/control surface in replacement of the flybar. In addition to having a mixer and added gyros for fore/aft and left/right, you would need the apropriate swash set up.
Has anyone thought of scaling their Trex? I've ordered a 21st century model, in which to convert. It is a UH-1 huey, the CIA version as these models are no longer in production, and couldn't find the US calvery version.
Here is a link to a marketer,
http://www.smalljoes.com/21stcentury...aircraft.shtml
The model is 1:18 scale for the Trex size helis, as well the UH-60 has been done from Eolo mechanics, and the AH-1 is said to only be compatible with a Shogun 400 chasis. I imagine the Hughes 500 can be converted with Trex mach. All 21st century models, gutted and running a brushless tail motor with seperate ESC. This will be a seperate bird for me, built from probably an GL450, Pheonix, or CopterX chasis.
Some links for those interested,

Cflight,
that makes sense to me.

The problem with setting your end points to limit throws, is that you'll be reducing the piro speed linearly.

RE: Official T-rex 450 XL SE Thread
guys,
I just installed the new 430xl motor in one of my trex's. All i've done so far is hover, but I went into idle up a couple of times. The gain in rpm was so dramatic, the main gear made a clicking sound the first time I tried it, even though the pinion gap is set plenty tight. I think this is going to be a powerhouse. So I increased throttle in point 4 to more closely match the idle up setting. Hopefully that will save my main gear. I was spooling the head in my basement and got a little glitch on the throttle. That happens in my basement sometimes, lots of stuff in there.... anyway the throttle hit for just a second and that time DID strip the main gear. I had the pinion set just like it is on my other one with the 430L. That's when I moved it in closer. I also have the Curtis Youngblood blades on it. I'm flying tomorrow and will report on the differences in the heli. I really like the Mavrikk E series carbons so these blades are going to have to be mighty good to get my vote. Also, as most of you know the 430L with the 13T is quite powerful. We'll see if the new motor makes it a worthwile upgrade. Already I noticed it runs warmer than my 430L's.
