Status: offline 		You are setting it up with your TX setting on 3D mode and not the 40 / 50 / 100 pitch curve setting. Also you aren't using digital trim to center anything to get the zero pitch if so then your servo isn't going to swing the same at both full up and full down. If the above doesn't apply and you still can't get it to work then move your rod linkage out one hole on the servo arm and start over on centering. It almost sounds as if your servo arm isn't in the correct centering postion and you shortened the linkage to make the upper 10 degree work. Good luck.

Thank you for your help, I understand what you are saying and I will check it out and let you know the outcome, also I 've been told to check travel adjustment which is set to factory 100% may have to alter, to maybe 115--130% to get full negitve swing, but not bottom out the servo at full positive pitch, it sounds like a fine balance, like I said in previous post everything is centred and level as per the instructions that were posted earier on this forum and also Bob Whites, I will give a good go over this weekend I've probably missed something
Cheers
Ralph

An easy way to help set up your heli, mechanically, is to check out the videos by Finless. There's a post here for a link. They are excellent. Once you set up the heli mechanically, you can set it up properly with the radio.

Thanks for your help!!

Thanks for your input; yes it’s a bit strange. At the moment I really haven’t had time to sus it out properly, question--have you set up your TX as per instructions in this post, I have and I think I’m getting confused with the CCPM setting’s the way I understand it those settings should only allow negative 3 degree’s and that’s all I’m getting because the instructions are for beginners not 3D flight am I correct? And therefore you can’t get negative 10 degrees pitch using the instructions in this post.---(is that right?)
Everything was going so well with T-Rex assembly I’m nearly ready to fly everything else is perfect!! I’m just stumped on this problem but not for long!!!!
How’s your machine going Larry?? I’ve watched all your video’s and you seem to have a handle on it. And that’s good to see, has the bloody snow melted yet? And is the weather improving we are heading onto our winter now, but it will not be as severe as yours it doesn’t snow in Sydney.
Cheers Ralph

When I get a chance I will go through my DX6 and tell you exactly how mine is set up, but I don't have time right now. We don't really get any snow here on the west coast of Canada where I live, maybe a couple of days a year. It got up to 26 degrees C today!

Status: offline 		Hello Larry
I certainly appreciate your help with my set up but I don’t want you to go to that trouble. This weekend I should have time on Sunday to check this heli- right out properly and there is truck loads of info- on the net about set up etc, so I’ll let you know how I get on.
I remember one of your videos flying chopper in the snow, looked COOL to me.
LOL Cheers Ralph

Status: offline 		I'm using the DX6 with my Trex 450XL. I have the mechanical collective and it works just fine together. I had to spend sometime at the LHS so they could go over some functions, but I installed the receiver and servos myself and was actually flying right after I finished the build. THey just helped me fine tune my adjustments because I wasnt quite spot on with my sub trim and pitch curve stuff, but I would say its a good option as far as the radio goes.

Status: offline 		Hey Everyone
I’ve worked it out!! I told you I probably stuffed it up!!! and indeed I hadn’t I just hadn’t read all the instructions, (same old story when in doubt) The flight mode switch when its off you can only get negative 3 degree’s when its on you can get negitive10 degree’s---- now I understand what is going on!! It’s the 3D configuration that I didn’t understand??? And I must say it will be a while before I go there LOL.. Ok now I can do some serious flying this weekend and finally get this project off the ground..
Cheers everyone thanks for your help!!
Ralph.

Status: offline 		wonder if you still have the trex setup info w/the dx6. I just bought a 450xl and dx6 and am trying to set up pitch and throttle curves. any info you can throw my way sure would help. I bought the brushless package w/esc from helihobby. The trex 450XL CDE I believe. my email is mdhdmh@wkblue.net. thanks.

Status: offline 		OK guys, here is the deal. I have been following that guide to set up the dx6 and I have some questions. First see a insert on his steps here :
http://www.digimemphoto.com/guides/backguide.htm

Now it all looks fine with the excption of a few spots:
1. Press scroll until TRV ADJ. is visible.
Press scroll and select the GER channel. (this is not scroll at all its channel)
Place the Aileron DR switch to 0. Use the decrease button to set +45%.
Press scroll until HLD is visible.
Use decrease and set to -1%.


2. this is the one that gets me:
Press scroll to advance to the Throttel Curve Menu. Use the channel button select TLS, T2S and THS and set the following values using increase and decrease.
TLS=100%
T2S=80%
THS=100% (I do not have THS it goes from TLS to T2S and back to TLS)

Any idea why I dont see that step?

Also I was able to get FMS working fine with the trainer cable and the SmartPropoPlus however here is the deal. Its been a while but from what I remember:

left stick up = vertical clime down = well down
in the flight sim I get mixed results... feel free to give pointers, at this point there is no way Im going to try the t-rex till I feel like I know what the TX will do in the flight sim.

Mike
