Bob,

I hope someone in Align is reading this forum They have a nice reputation for listening to their customers anyway. I think I'll try your canopy-new-holes-in-the-frame method later, I don't wanna fumble around with all the servo links hehe

Btw, I've already finished my bird, had to take the leap of installing the tail end without the video..I just hope I did it right

Anyway, I'm now reviewing your CCPM videos and how to remove the interactions as I've just done reversing them for the right travel...wish me luck!!!

Bob,
I am new and I have a TREX 450XL CCPM that came with 430L motor and BL-25G ESC.
Which video will help me get started.

Thanks.

Prynhawn da BOB

Just a big thanks.
I dont have an HDE But an ARK 400 nearly the same thing i think
I was looking at the vids and it helped me a lot to set up and fly my bird and would not have had her set up correctly with out your help.
Cheers Mate

Use my HDE build videos for some of it (frames, etc) then use my other vides which are more realted to the SE but the CCPM setup should help.

Default HDE tail setup fine points

Hi Bob,

Well I dived in and went ahead with the HDE tail assembly. With the experience of the rest of the build under my belt and some careful study of the diagrams, it proved quite straight forward (at least I think so, unless I missed something subtle).

I found I had to reduce the rudder servo travel to about +/- 35% to prevent the tail pitch slider hitting the stops. That means there's only maybe +/-5deg of pitch range in the tail rotor, is that OK ?

I was thinking of drilling a new hole in the servo arm closer to the centre and then increase the range as my gut feel is that reducing the mechanical throw and using more servo range up ould a be better solution. It won't give more tail pitch but I think more precise control. Is that a valid assumption and a reasonable way to setup the rudder servo ?

One final question. I have an MKS GY191 gyro which seems to be working fine. Only thing is I cannot tell the difference between Rate and HH modes (no bicolour LED or anything). I have the gain set to 40% in both modes. In one of them the gyro is tending to slowly drive the rudder to one end. In the other it tends to input a correction then go back to neutral. Also the rudder position tends to jump when I switch between modes. Is there an easy way to identify which mode it is in from the behaviour ?

Thanks,
Kenneth

Ken, sorry I have NO knowledge of that gyro. With a 401 you want as close to 100% for travel limit as possible! I cant say for that gyro sorry.

Well Bob, I'm done with the bird. Do you have any experience with the telebee/align gyro?? that's what i'm using and it seems that I have a problem, tail keeps spinning and won't stop until I give counter rudder...my rudder servo is moving to one direction only?!?! all channels correct though, all limits ok

Get the mechanical set up on the tail. Put the gyro in non-HH and trim (using rudder trim) to hold the tail.

Then adjust the servo placement on the tail or the pushrod links to hold the tail at the same spot while getting the tail servo to center. This should allow you to put your rudder trim back to zero.

Now that your set up your gyro should be able to hold.

Finless - I'm a newbie to helis and I just wanted to thank you for your build videos. I recently got a CDE CCPM kit and while your videos cover the HDE model, your videos touched on a number of similar areas which helped me with my own build.

Once again from this side of the world - THANK YOU!!!

Hmm.. need another video... why it's a bad thing to hold the tail while testing the movement of the swash...

After spending a few hours making sure the head etc was right... I screw it up by hitting my thumb at speed....

Tally... very sore thumb, broken blade, stripped main gear, not sure what else walked away before I did anything else stupid..

Bob, I've got a crisis and no clue short of jumping off a cliff on how to solve. And no I'm not talking about belt tension, although still on my mind.

After watching the "quicky" vid, I realized I had some setup errors on my HDE. I realigned everything and reset the servos properly. Now everything is lined up correctly. What I hadn't realized before, (I hadn't to this point thrown it into idle up) was I'm only getting -5 to +6 pitch in idle up. then I double checked normal mode and found I had -5 at mid stick. Throw it into idle up and it's +-0 at mid stick. Where did I screw up? I figure it has to be in the 7C programming, but everything is set to your curves so it should be correct. All endpoints are still 100% so I'm not limiting travel.

Helpme, help me!!!

Zooland, not that I'm an expert but I also ran into that problem. I have a CDE, but I think it can apply to your HDE. I didn't have - pitch at midstick, but about +3 only. I went ahead and lengthened the links from the washout upwards.

Hope that helps out
Cheers
Shaun

zooland1,

what are your PITCH curve numbers for idle and normal?

Also make sure you turned OFF anyu dials or sliders that have to do with HOV-PITCH and PITCH TRIM. You could have a know or slider effecting your curves. This seems to be a common mistake lately..

Bob

Never mind some how I did have end points set on channel 6. I don't remember doing that, but anyway. Did you tell me to in a vid? :? I always do what you say, so you must have told me to. Thanks

Yes I think I did

Set the radio to defaults BEFORE starting...... Hey it's OK we ALL make a mistake now and then......

Shrug it off and go forward!

Bob, excellent videos! Awesome. I have just ordered the XL with HDE and it should come in a few days. But I have already downloaded the manual to study it and I must say it is not very good for assembly. Sure, it shows exploded views of everything but it has very few words giving any details. The steps aren't that clear and order of assembly could be better. Plus my eyesight is not the best and the manual (at least the dowloaded one) is not too clear and the graphics hard to read in spots. I don't think I will be able to assembly the XL CORRECTLY without your videos!

You mention lockite and CA and some kind of special pliers. Could you give some more details like brands and where to purchase them? Thanks again.
