Uncle Sir

I run the DX6.

Please don't take this personal, but you may want to reinstall the stock TX/Rx and learn to conqueror the hover first...

You will learn a lot of the natural characteristics about the heli first and then you can understand what the DX7's setting are supposed to do and what is natural for the heli.

Tell me what exactly your problem is now with you current settings...

Rob,
sorry for the delay in the responce. I did think about reinstalling the stock system, but i called Horizon one more time and we discussed settings. Make no mistake i understand a computer radio like the back of my hand. The least powerful one i own is the JR 6102. Without them i would not be able to fly my giant scale 3D stuff. . . and make it do cool stuff anyway. But when it comes to helis and pitch and pot and gyro and on and on and on. . . I am a newbie. So, i gave it one last shot with my tiny heli skills and my LHS owner and we worked it out. . . it is pretty much stock exept the expo for the rudder.

FOR ROB AND OTHER HELI-PROS TODAY;

I have been indoors practicing RADDS school of thought and am up to hovering tail in. I am doing very well especially for the smaller space i had to move to (the wife and her new years party. . . my buddies and i are looking at my planes and watching my heli!!!!! party on wayne, party on garth! Anyway here is a new? problem.

for the first 2 or 3 flights on a pack it will respond PERFECTLY. It hovers without much input from throttle or rudder. However, after the first few flights (they last 25 sec or so) I will establish a hover and then it will decend, then the air will bounce off of the ground then it will rise a foot or so, then I will establish a hover again (4 or5 feet or so aloft) then it will do the same thing. It seems the longer the pack is run, the worse it gets with the 'up downs'????!!!!!! I dont know what to do. I AM SURE that the washers are in right, it is lubed correctly, and there isnt much vibration from the bird either. My blades are a little nicked, but track perfectly (flat bottoms). I HAVE NO CLUE WHAT IS UP. I guess it could be stick collective, because when i tried the whole take the blades off and the oval things off and see if your rotar head drops on its own weight (the test for sticky collective) it would drop decently, but not quite all of the way, BUT when spooled up the rest of the way is not used and i could not get it to drop perfectly durring the test either. WHAT IS THIS PROBLEM. . . . it changes it from flying a heli to just reacting to a heli.

p.s. I kept trying to dial in the gain and trim again on the 3 in 1, but i confused them and it took me 2 packs before i realized i had them backwards. durring the process and the realization i said a few, of what the wife calls, 'hobby words'! So happy new year and theres a laugh or two guys.

Check the spindle to see if it is bent.

Also, make sure the gear mesh is right.....

Hope this helps!

both of those are good, but my rotor head set does not slide easly up and down my center hub. . . even with everything off of the center hub and the rotar head broken down to just the slider it is a little sticky. . . i have lubed them but i think its a no go. . . do they make aluminum rotar head/centur hub sets?

or is that kind of normal wear and tear stuff?

Is the friction between the head and the center hub with or without the servos attached. I was having a similar problem and it was a stripped servo. It seems that is a common cause of the "Yo-yo" affect. Just a thought, Joe

I took the whole rotor head off and then ran the heli. That's when I found the out of true on my main shaft. Hope this helps. Let us all know what you finnaly figure out, Doc

A little expensive, but Ive flown it for a couple of months without noticeable wear.

comes in blue and aluminum. GREAT product support.

orlbuzz

WOW! that is expensive, orlbuzz! But i bet it is worth it!

I think that i might sit out of that upgrade, i have looked at a few full alum rotar heads, but i can not decide on one. . .they are a little more then the center hub at orlbuzz's link. I am going to try some graffite and if that doesnt work then another type of grease. If both of them dont work then i will look at either that center hub or a full head.

I have checked the servos. . .they are good
I double and tripple checked the main shaft. . . it was good, BUT I SAW A THREE OR FOUR SPREAD OF STRIPPED GEARS ON THE MAIN DRIVE!!!!!!!!!!!!!!!!!. COULD THAT HAVE BEEN IT???????

anyway i am going to pick up a new mainshaft/gear and a new set of blades in the morning at the LHS. . . I might look for another type of aftermarket center hub if they have one.

OH, i think i might have the House Hold 6's (wife) approval on the new Trex 600 !!!!! I am going to shop around but i dont care for a gas heli, but i would like a large one. I'll keep the helis for the house and yard and the big planes for the field. It might be a month or so around my birthday. . . but i need to seriously practice for this thing. One of the guys i have been training at the field is an excellent heli pilot (but cant fly a plane worth crap!!!) and he offered to buddy link up with me on the TRex if i do get it.

Anyway I will report what happens with the heli
You guys are great. . . thanks a million!

-Evan

p.s. i put a post in general heli discussion about what i would need for the 600. . . if you get a few check it out and give me some suggestions if you have them. . . thanks guys!

correction. . . the post is in the beggins forum for helis

I used to chuck my main shaft up in my drill press and polish it with some emery cloth.

Then lube it
