Status: offline 		One more thing guys, will the stock Dragonfly 36 reciever/ESC that is currently running the 12volt 630mah Ni-Hyd battery, run on a 730mah Li-Po battery with no mods? And anyone with any suggestions on good/important upgrades please feel free to enlighten me. It flies good except it fish tails alot and makes it difficult to fly. Keep in mind that I will have this thing doing 3d or atleast hover inverted.

Thanx,

Chris

Got a 36, my first helicopter and should have gotten a different one from what I've been reading. My won't lift off like the others I've read about. Will get the motor and esc. Which pinnon should I get. 11t, 13t, 15t. I tried the link, but got a blank page. Please name brand and what battery I should get.
Thank you

Status: offline 		Thank you Cheatscalc,
New to helli's, and really needed this explanation on tuning the tail and head. Just got the 36 today, and went through your thread with the TX on, everything zero, and out of the box I would be shocked if it flew. Also if my understanding is correct with helli's, the CG should be directly under the swash plate, it's not even close with out of the box items. Anyways, thanks for the directions, they are a real help to those of us who are heli challenged. lol

Status: offline 		l have run a 11.1v 1800 lipo pack with stock motor(brushed) and it makes a world of difference...the stock battery is just to weak for this heli---but with a good lipo battery l can hover it around in my living no problem for around 5-7 minutes ----but a brushless motor is the way to go ----longer flight time and way more power(align 420)scary power l would say

Ok, li-polys won't make a difference unless the C rating is above 10, but, I'll say they're one of the best investments for this heli!

Now, the align420LF is a GREAT brushless motor, the best of it's kind for this helicopter. If you put a large enough pinnion, it'll probably strip every gear with ease, which, isn't a good thing but it shows this motor has some power.

The align needs to have a 11T or 13T pinnion on it, any larger and you're probably putting too much stress on the frame, but most likely not the motor. I can fly with my heli at 700g and that motor is barely warm after a full li-poly pack.

Also, make sure your brushless esc is on LOW to MED freq settings as the High setting is making the motor too powerful. Soft start is great, but, once it's spinning put the stick at 1/3 throttle, and wait, once the motor is at this postition jump the throttle up a notch or two and the motor should speed up to that instantly. This means the soft acceleration (it'll slow down slow as well while this is engaged) has turned off and it's time to lift off. Don't worry though, when you've set down and put thottle to off it'll start up slow again and you've just got to repeat the process.
Brake should always be off, I've crashed with it on, and well, It did the death jig on the ground as the motor dutifly slowed down at the set pace. this heli has AUTOROTATION so you DON'T need the brake, I only suggest it if your heli doesn't have that.

heh there, that's my quick review of the align420LF, the BEST brushless motor for med sized electric micros.

Status: offline 		heh thanks, I'm glad you bumped it, I'm sure there's some who need to see this, though, I don't have anything to add, yet, still gotta order the parts, then I'll get to some more info on setting up the heli.

Status: offline 		Thanks for all the tips, guys. I wanted to see if you had any tips that are specific to the equipment I'm about to use. I have a Blade CP also, which I fly quite a bit (LiPos changed my life....) The 36 was my first, but had bad: Gyro, 2 servos, and apparently the receiver also. I got tired of arguing with the ebay supplier. After drooling over the Trex SE model daily, I decided to replace all of the electronics and set up the 36 like I would my future Trex, then switch the components over once I'm worthy. I stole the components list from a pro pilot's set up in RCHeli magazine, except for the 2.4ghz radio.

I have collected the following brand spankin' new gear and plan to assemble it over xmas: Fatuba GY-401 heading lock gyro & digital tail servo; Align aluminum tail servo mount to handle the bigger servo; Align 430L brushless and 35 amp ESC w/Governor; Spektrum DX6 2.4 ghz transmitter, receiver, and s75 micro servos; E-Flie 1800 mah 3 cell LiPo.

I'd really prefer not to burn anything up through ignorance. Any help would be appreciated.

Status: offline 		hey i got another setup question for ya,
my #36 came with a brushless motor and esc that says walkera on it. I have tried yesterday to install it , and have a couple of questions.
On the ESC there is one set of wires that go to the battery, 3 wires that go to the motor, one flat clip that goes to the receiver, but there is another mini connector that has 2 prongs that stick out. Where does it go? Maybe the other end of the mini clip that comes out of the receiver?
How do i put the pinion gears on the motor? I know superglue is not the answer. But will blue locktite do the job?
Do I need to use the pinion with 11 teeth or 9?


I also got a battery question for ya. If I move to the 2200mah 11.1v with 12c, will the additional weight defeat my new added power? or will it lift off better?
thanks paulb.

Status: offline 		2200mAh is the recommended size, go for it, especally since it's got a good discharge rate (I use one of the wimpy 2200mAh blue ones and it works just fine, on my align that is)

I'm sorry to say, but, I've NEVER heard of a clip like that, mine doesn't have it, just attach everything but that and try it out. It should work just fine, and that MAY just MIGHT be there so you can use that instead of the servo connector on a 4ch Rx and just plug that into the slot where the old motor went and use that for the speed control, but really I have no clue. Be CAREFUL with that walkera, they're known and prone to odd problems, if it doesn't work send it back and go for the align ESC and motor.

I thinks most people use 10T pinion on the 3200Kv Walkera BL motor.

Status: offline 		heres a sticky one for you, I have fixed many problems on my #39 from overtight tail belt to a battery not fitting however blade tracking is just a pig!!!!!! I have no problem setting up my caliber 30 blades but half a turn on the #39 puts the blades on a oposite track ie red was high with half a turn blue was high?????? cant change any less than half a turn lol also have tried different blades,,,,there is alot of slop in the linkages though,,,also setting that dam pzt and plt....I thought pzt was pitch zero trim and plt was pitch length trim>>>

Status: offline 		hmm, the pinnion choice is kinda hard... I'm not sure if the 9 would give enough head speed while the 10 may be an overload (it shouldn't though) I'd say go for the larger, I use a 11 T pinnion on my align420LF and it handles it really easy, though I'm wondering what a 13 or 15 T pinnion would do...


UPDATE!

the next section, dissasembly is coming soon! hopefully in 2 days (if grandrc's shipping holds true for 3 days every time) I'll be getting my new main shafts, booms, blades, and tail shaft in this means I will explain in detail the easiest way to remove a main shaft, the tension of the belt, gear mesh, and basicly how you would go about taking your heli apart.
