FOr some reason it is NOT seeing the throttle signal from the RX. bad connection? Wrong channel on RX? pin backed out ont he connector?

Bob

I have checked the conectors on both the cabel from esc and the RX. It seems ok, But no more then three beeps. I have orderd a new ESC but if it´s the same with that is it the motor or the RX that is faulty?
Thanks!

You could take a spare servo, and plug it into the throttle channel that would tell you if the channel is working.

Great Idea! I gonna test that asap! :thumbup:

I´v tried that now with another servo in the bird and it worked fine when I puted it in the throttle chanel in the RX!
So it must be an faulty esc that I have? :confused: Everything els works!
Need some input! :noteworthy

[Finless]

Sounds like either a bad ESC or possibly a bad crimp on the wires at the connector to RX for the ESC? You might pull the pins out of the connector and check them. 3 beeps then nothing means the ESC is NOT seeing a signal from the RX. Check the signal wire to the ESC.

If you have a ohm meter use a stick pin and poke through the insulation of a wire near the ESC and use the meter to check continuity of the connector to the pin in the wire near the ESC. This will show if there is a break in a wire or a bad crimp of the connector on the wire.

If that checks then you have a bad ESC.

Ok thanks Bob! I will do that!
It really sucks when you whant to get out and test it for the first time! :o

I´v got a new ESC now and it works great!
I love the bird!! So much better than the 450!!!

Isn't it! Look at the price difference!

How cares about the money if you really are into this?

Question regarding ATG v3. The manual says not to use a 9256 on the tail with that governor.. Is this correct.

Control arm endplay question, even with 2 washers on each side of the shaft between the control arms and frame I still get quite a bit of side to side slop. I tried switching out to the metal control arms but still get play with both allens tightened down tight. Is this side to side movement normal?

How much slop is "quite a bit"? I believe Finless states in one of the videos that a little bit of slop is OK.

[Spek]

Yea I went back and viewed his video again to double check, he said a little was ok. Id' say mine looks like 2mm side to side?

[TheBum]

I wouldn't think it would be that much, but I'd have to check mine at home to see how much I have. You do have all the frame braces installed, right?

[Finless]

2mm is more than I have seen with both shims in... BUT again realize this is not a fast spinning shaft etc so in reality the inner races do not really need to be captured. Fly it and I bet you will be fine...

Finless,

Great videos, I would be lost without them! My first full build and a nitro noob to boot!

How's this for a set-up:

TRex600 NSP with Hyper 50, Align pipe
HiTec HS645MG's on the cyclic
Futaba S3001 on Throttle
Futaba 401 and S9254
The kit shipped with an Align RCE-G600 governor and RCE-B6T 2-in-1 reg
Futaba R617FS RX (but does not work with my Futaba FT6EX TR (?) so not sure what to do about the TR yet!

Your comments gratefully received.

Regards

Shaun

Hey Bob,

I just buildt my CF looking at ur vid. thanks for the video. it waz great!! But I am having trouble understanding your explaination of 80-100 thing with the gyro. I am using a 401 gyro. also, my tail servo came with screws, but nothing to secure it with. and does a double horn with a 34mm across horn work for the 401 gyro? so its 34mm from the farthest hole, to the other farthest hole. and this measurement isn't diagonal. just straight up and down the horn. thanks!!

oh and feel free to reply to this everybody even though I addressed bob

OK. The 80-100 reference regards the limit potentiometer on the 401. It should be between the 80 and 100 marks for best performance. If it's less than 80, you need to more the ball on the servo horn closer to the center of the output shaft; if it's more than 100, you need to move the ball farther away. At least, I think I got those straight.

ok then, Bob says pitch and aileron on the 2 servos. i am going to set my servos up as pitch on the right (if you r looking at the heli from above) and the aileron on the left. I dont get his servo setup part when he points all the servo horns at the same place to see if it is reversed. and also, does pitch also mean throttle?and also, if you look on the Trex 600 manuel, page 18, it says to put pitch into AUX 1. note that I am using the Futaba 7C not ^ channel. wow, that was alot. well, please help!! i've spent the last 2 days only on this thing!!!

[TheBum]

That'll work.

I dont get his servo setup part when he points all the servo horns at the same place to see if it is reversed.
The whole idea is to get the collective pitch (different than the pitch servo, although the pitch servo is involved) working first. Collective pitch is controlled by all three cyclic servos moving the same direction so as to move the swash plate up and down on the main shaft. By getting all servos at least going the same direction when applying collective pitch from the transmitter, even if it's the wrong way, then you just have to worry about getting them to go the right direction. It really simplifies the setup.

and also, does pitch also mean throttle?
No. Throttle is on a different radio channel from collective pitch, even though they're both controlled by the same stick on the transmitter. You still do have to worry about the throttle servo going the right way, but you just use the reversing switch for that one channel in the transmitter to change the direction.

and also, if you look on the Trex 600 manuel, page 18, it says to put pitch into AUX 1. note that I am using the Futaba 7C not ^ channel.
I assume you meant to say "6 channel" and accidentally hit the shift key. The AUX1 reference assumes a Spektrum/JR radio system. Somebody other than me will have to tell you the channel to use for Futaba.

[191052437]

thanks TheBum!! so, when Bob says he is putting pitch, which channel does that go into? and how do I know if the servos are going the right direction?and yes, i meant 6 channel, but i pressed shift. good call there!

SO DOES ANYONE HERE KNOW WHAT CHANNELS TO PLUG INTO FOR EACH SERVO? LIKE THE GYRO, AND THE PITCH, THROTTLE, AILERON??

[TheBum]

thanks TheBum!! so, when Bob says he is putting pitch, which channel does that go into?
Aileron, pitch, and elevator. They move together the same direction to control collective pitch.

[191052437]

uhh, my elevator and tail, and aileron servos are working, but the pitch servo doesnt even power on and I tried plugging it in in every channel. maybe the servo is damaged inside or broken?? and also, I am using the Trex 600 "F Servo Horn Set" and the horns are made so you have to put the link ball in the inside of them, but when I put it in, I realized that the Servo link ball and the other ball link it has to connect to doesnt line up. so the servo link ball is farther towards the frame than the other ball link, so the ball link arms are in an angle so in order for me to make the arm fit perfectly, I have to change the length of the arm a tiny bit. This situation is the same for both the pitch and aileron servos. is this ok, or should I get new horns?

[Finless]

Dude..... I bet you have not set your radio for 120 swash! This is a CCPM heli and you cannot have your radio setup for 1 servo.. It HAS to be setup for 120 to make tHe mixing that allows 3 servos to work together!

If this is a DX radio, go watch Jermo's DX7 radio setup video and pay attention...
