Okay this might be long, but if you own a dragonfly or a copy/clone of it, it would be bewho of you to read!!!
Note: as I explain this I make it seem as if I have done it all in one day, when in real time it has taken me about a month or so if not 2.
Okay, I got my heli in the mail from off of e-bay, got all excited and had to charge the battery right away, while the battery was charging, I got a little more time in on my flight sim. After the battery time was up I dashed for the spare room in my house (tiled room not carpet). To my dismay I couldn't get the squirrelly thing to hold still on the ground (not even at lift off and problems) I figured it was me... well after 2 more battery charges I decide to look up and see if I can find some know problems and help sites. I found a few before coming here, (if you read my long thread "new problem" you see most of the progression of my problems). Any way I took and made sure the blades were balanced with a ruler (balance them on the ruler separately and see if they end up balancing at the same place by using a marker). After finding nothing wrong with that, I moved to the next problem, leveling the paddles. This part was kind of pain staking. After doing this with a screw driver and some needle nose pliers I put it all back together again and then (I can't remember where I read this, but it helped a little) used tape and taped it down to a table. I kicked it up to take off speed and looked and listened for vibrations, then after seeing none I took and kicked up the speed slowly to top throttle. I noticed a little vibration so I tightened the blades to as tight as I could, and then tried again, vibration gone. After all of this I drained the battery out again then gave it about 5 minutes and charged it up again. I knocked up the throttle enough to get it light on the skids again and I STILL could not keep it still. Well low and behold I noticed something though this time that I have been mostly ignoring (due to excitement most likely) the left - right cyclic has been twitching, and twitching quite badly by now. After about 3 more battery charges, about mid flight (if you can call what I was doing flight) the darn thing completely stopped moving. The servo had burnt out. So after reviewing some places I find out that hobby people (
www.hobbypeople.net) had the best price for me (especially since I am military: they ship free to military addresses) I purchased the HS-55 J plug. I took and installed it (I had to use wire cutters to chop off the little knob or whatever it was in order to plug it in) and every thing seemed so much better, but then about mid flight again the other original servo burnt out. I then again ordered another servo. After putting it on, it was no joke like night to day in the quality - stability & ability. No joke, but still something was messed up here. I was still doing some kind of hula thing. I found out that if you mess with the tail boom a little and rotate it clockwise a tiny bit it (VERRY TINY BIT) it helps in the stability allot!!! NOW I DON'T WANT ALOT OF E-MAILS AND POSTS TELLING ME I AM WRONG AND I AM GOING TO BE MESSING UP NEWBIES BY MENTIONING THIS!!! WHAT WORKS FOR SOME HELI'S WON'T FOR OTHERS!!! MESS WITH IT YOUR SELF AND FIND OUT!
Note: I noticed that when the battery it about to go to its idle down speed your heli will become very unstable. Just land it and let the battery drain. It’s not your heli being messed up.
That it about the end of my huge adventure starting out adventure in helis. I am still learning to hover better.... I never said I was an expert!!!
