E-Sky Belt CP Blade Pitch Angle

LOL well now that you mention that the problem could be you

Like i said, its not a lama and you have to control its ascent it dont go up straight on its own.

Even if he can't find a physical problem with the heli doesn't mean that it's the pilot inability to fly a heli, is it? I say this because he said he was able to hover/fly it before so that makes me think that he does know what the heli does when it starts lifting. Based on that, if it's not the pilot it has to be something with the heli itself that he can't figure out. Also, because of the fact that he had to replace the same servo many times... makes me thing something is casing the same servo to go back... so I think there is the key of the problem. That's must my guess by looking at the thread.

My Belt-CP also goes to the left (tilts) but because of the training gear I have on gives me enough time to use the sticks and hover it.... no for long because it's just to hard but I'm still able to. I hope to be able to fix mine this week

Helicopter will ALWAYS drift to the left on liftoff... Its a normal thing for all helicopters with single rotor..

Simply give a tad of right stick until it lifts off the ground... As you learn to fly this will become natural and you wount even know your doing it.

PS Sorry didnt see where he said he could hover will have to re-read the entire thread.

OK guys I think I'm on the road to recovery now. I don't know what the problem was with the font servo but I damaged 3 of them in that same location. As I said I checked all the linkages and everything else that I could think of and everything was 100% free. I found that the gear that was being damaged in all those servos was the same gear. And it retates less then 180 degrees for full operation of the servo. So I repositioned the gear 190% in rotation from where it was damaged and the servo works fine again. This is a good thing to remember when you damage a servo.

I still need to do some fine tuning of the linkage rods but I did a little test flight in my garage just now and it lifted off almost as good as new. So as soon as I have the time I will reset all the blade angles and see whathappens. Wish me luck.

Good think you can kind of hover already. It took me 3 - 4 attemps (batteries) to hover.

Hi!

Not sure if this thread is dead or not but I want to comment on a similar experience I had with my Belt CP. I bought it used. Right away I found that it wanted to make a hard left and backwards flip as soon as it became light on the skids. Even with full right stick it wanted to slide across the ground to the left.

After hours of fussing with it and blade tracking a joke, I took it up to my LHS. The LHS spent an hour on it and admitted that they were stumped.

Just before I tried to return it as a lost cause, I took one last hard look at it. I discovered that the flybar control arms and mixing arms seemed to be backwards from the pictures in the book. I also found that the control rods were attached at the wrong end of the mixing arms. Once I reversed all of this the bird hovered quite well.

Thanks and I hope this helps someone,

Chris

Hello all. I am trying to move my belt cp from the orig. trx to my dx-7. It was ok on my runup tests with the stock trx, but now the pitches are off on my dx-7. I am not that new to flying helis, but I am a complete newb in setting one up. I have watched all the finless videos and read tonnes of threads, but I'm still stuck.

In idle 1 I have stick at center and I get +6 degrees on one blade and +2 on the other. Is this possible? I noticed no vibrations of anything being bent before. I guess to set zero pitch I need to lengthen the vertical rods to the swash or is it the next set up? If it is the next ones up, it looks as though I might be out of threads if I go very far.

Thanks for any help.

Hi

Have you changed the servo's too?

whate are your pitch curves?

Idle up should be 0,25,50,75,100

With this curve, start by making sure your srvo arms are at 90 degrees. To do this you put the horn on the servo as close as possible then use your sub trim.

Then use your links to set the pitch. To do this disconnect the motor switch the radio on, put it in idle up, put the throttle stick central and check the blade pitch, it should be zero and the swash sould be in the middle of its possible travel.

If it's not adjust the links till it is and the swash plate is dead level

Then you need to use the travel adjust and swash mix functions to get the max range of collective and cyclic out of the head, you can allways use the dual rate facillity or expo to tame the heli a bit if this makes it too responsive.
