    Status: offline     		boris, did you have the throttle set to full before you turned the transmitter on?

    Now, I'm going out on a limb here because I don't have this setup, but....
    My Bladerunner clone has a safety feature where the throttle won't work until you push it to full and then back down to zero. Maybe these ESCs have a similar feature, or maybe it's just that you don't get the beep codes unless the throttle is set to full before you turn on the transmitter, so when you're in setup mode the motor won't run. The ESC may need to see the motor attached before it'll enter setup mode. If someone else can't test it, you could always pull the motor and give it a try.
    Don't forget to let us know what happens.

    Just use the forums as they are the most useful tool available. I would be happy to swap emails as well as i just love to chat about helis. I'm on my second one. My first heli was a honey bee 2 and for a total novice like myself it was very difficult to fly. I love my #36 but its not without its grief with the standard radio gear and brushed 400 motor. I have made upgrades and i now get about 20 minutes flight per pack.

    If it is spinning opposite the blades then your rear pulley may be slipping? I'd check that the retaining pin is seated well (perhaps ca'd in as well).

    The best way to test the brushless motor and esc is with the BL motor out of the plane/heli, you can safely check your esc program (soft start, brakes off...etc) and spool up the motor slowly. If the motor turns the wrong direction, just swap any 2 of the 3 motor wires.

    Status: offline     		Boris, as I said, I don't have this setup, but I'm pretty good at figuring these things out.
    To try this, please take your motor out of the heli as I don't know what might happen.

    The setup mode should play a tune and stop. After it stops, you'll either hear nothing, or a continuous tone. Move the throttle to the lowest position and wait a few seconds. Then get back to me and tell me what sounds it made. It should have just set your Brake to OFF. I expect you'll hear a lower tone, but I'm not sure.

    Status: offline     		heh NOZ your belt, or the tiny plastic gear theat moves the belt is slipping, look in these two places for stripping gears. (the retaining pin is in the gear, in part where the tail is connected to the body, just before that there's a metal rod with two gears attached, one with the belt riding on it and the one with the that attaches to the lower main gear. ok if you look at the smaller gear and see some jaggedish plastic coming out the bottom it's stripped. try holding the tail blades still and moving the main ones. if it slipps you know your problem, the other possible canidate is the little gear in the tail thats attached to the tail shaft.

    OK, so I got my #4 a couple days before I got my 36 and I've got to the point where I can hover it for a few seconds at a time, most of the time. My 36 came in without a battery, but the vendor sent me one (NiMh). I couldn't get the 36 off the ground and didn't know if it was the motor or the battery. So, I got a deal from the vendor on the combo LiPo and cheap charger and it came in today. I charged it up at work so I could give it a whirl (I like saying whirl with helis) when I got home.

    I just popped it in and tried it. Set PLT at 11 o'clock and PZT at 1 o'clock. On my livingroom floor, no training gear because I just want to see if it'll get off the ground with the new battery. I start bringing up the rpm and I can tell the rotors are spinning faster than they ever did, even at full throttle, with the old battery. I give it a little more and it sounds like a turbine powered chopper. I give it a little more and WOW, up she jerks about a foot off the floor like a missle and I instinctively cut power just a bit. For a second I'm just stunned and can't move, then I bring it back down. When I say it jerked up, I mean straight up. Just straight up and stayed there a foot off the floor, not moving, not wandering, until I brought it down.
    I think I'm going to like this thing.

    that is impossible..

    90% cant get a 10 seconds flight with that stock brushed...

    btw i doubt ull get liftoff like that again becuase the first flight (without any upgrades) drains the battery fast and you wont be able to
    get that sort of power again

    if u think thats impressive, get a brushless motor. (best choice will be align 420lf as its very good yet not expensive)
    also upgrade the li-po, im assuming he sent u the blue li-po? those are horrible 6 cells, (you should get 3cell li-po from good brad like thunder power)

    you should also upgrade the servos as well, and if u have any more money left, replace the tx and rx.. walkera electronics are rubbish
    ull notice a big difference

    I had the same experience on my #36, sometime she just pop up. I only can hover her during the first 3 min at about waist high and she starts to settle down gradually and stay inches above ground for another couple minutes. The stock motor is steaming HOT, can't even touch it, I have a bad feeling about my stock motor, it may only last for couple more flights.

    btw i doubt ull get liftoff like that again....


    I did it again to show my son & daughter, and then again to show my wife.
    I put the training gear on and took it out on the deck (15' x 30'). Not much breeze, but I had to have all the lights on.
    I popped it off the ground 3 or 4 more times, then it had a hard time lifting. So, I put it in Collective mode and it would come up about 3 feet for 3 or 4 seconds and I'd set it back down. This worked 3 or 4 more times, then I had to give it a 5 second rest in between or it wouldn't lift off. The motor and battery were only slightly warm, but it wasn't running too long. So, yeah, an Align 420 would be nice, and I do plan on getting the setup, but for the moment this will work and I'm supposed to be practicing on my #4 anyway

    The lift off isn't what impressed me, it only surprised me. I was impressed that it hovered in one spot with no real input from me. My #4 can't do that. I mean, I've checked the 36 over before (even though it wouldn't fly), but aside from loosening the belt a tad, it's just the way it came out of the box.
    I've got 2 questions.

    1. On these cheap lipo chargers, when the LED changes from red to green, is it done charging?

    2. How is everyone mounting lipo batteries, getting the right balance and having the canopy fit?

    Status: offline     		I'm in the process of rebuilding a #36 by using another kit for pieces and most of my first one.


    I observed the following:

    1) The new one is overall put together way better than my first one. I couldn't find a single!! Stripped screw.

    2) The new one's tail slider was sticking. This took a long time to track down as I thought it was the belt tension etc. Eventually I had JUST the tail pitch slider with the two links on it (no longer on the shaft etc). It wouldn't spin very well (less than 1 rotation freewheeling the two pitch control links). I looked carefully at it and it seems that the brass insert was expanded a little too much and was squishing the bearings. With some tweaking with pliers (not squeezing, just massaging the brass bit back and forth a bit) it suddenly loosened right up. Instantly free wheeling I put it back on the tail shaft and it was still super.

    I then inspected my old one and noticed that although it was a lot better it would also exhibit the same problem. This is how to check

    a) pop off the bell crank. This involves undoing the screw that it is held in by (taking care not to lose the washer/screw/insert in the process) and sliding it off the post on the tail slider.

    b) Make sure this is out of the way.

    c) Take apart the tail case. I think there are 6 screws (two long ones hidden by the tail fin sticker, and 4 short ones). Take care not to lose the bearing inside the belt tensioner!)

    d) Carefull slide the tail shaft out of the case (the pulley side of the case) as it comes apart. You may need to give it a gentle tug to come apart.

    e) Take the side with the blades , pulley, and pitch slider and put the rest aside.

    f) Turn this assembly so the tail blades are hanging down. Move the pitch slider so it is closest to the blades and won't contact anything. Give the blades a spin and ensure they are free-wheeling nicely.

    g) Slide the pitch slider back up so that it will catch on the tail casing and attempt to repeat the spinng. You can do both of these spin tests mostly horizontal if the pitch slider wants to slide down.

    If you notice a difference between the two (on one set it was huge! and on the other it was a bit noticable) then you have a "sticky" pitch slider. This will eat power (bad bad bad). I'm going to shop around and see if I can find a compatible piece for a good (read cheap) price as the quality is a little iffy on this part from my 2 sample size test


    3) The elevator assembly AGAIN had the servo pushrod going to the wrong side (the walkera manual exploded diagram even shows the right side!).

    I'm thinking these are all indications of poor quality control on the assembly side of things. I wonder if it is possibly to get a 36 in "Kit" form?
