Logo 600 3D.. Tips & Info For New To Big Heli Guys

[wlfk]

I bought mine on Ebay for about £3. They seem sturdy enough.

I agree it's annoying. On the other hand, if you wanted to change this you would get a less linear response and you might have to redesign the rotorhead if you wanted to retain the same range over pitch/cyclic with less servo movement.

you dont NEED their arms, just need something that is simular in length, its not 100% essential to get it exactly that long. as long as its within a few mm i think its fine. QUK make some nice arms for helis too. http://www.quickuk.eu/cat/general_parts/control_system.html i think the round ones work well for the logo

[ShuNut]

I ordered already. thx anyway.

Edit:
Just wondering if theres any more things i need that i dont know about, what about screws for the servos, are they included in the kit or do i need to get some, if so what type\size etc ?

Thx

[Klinger]

I know you've already bought the arms Shu but i just used the large futaba wheels, found the sweet spot for 90 degreee mounting and fashioned a horn with a dremel, took like 10 minutes.

Hey. They're in the kit but be aware that the swash servo screws and the tail servo screws are different. Swash are 2.9x14 self tapping phillips and the tail is 2.5x10 hex head bolts. Got me last night :)

Just one other thing to note that is not in the manual. You will need to cut your tail servo arm down to clear the frame. It will be obvious when you install the tail servo. No biggie though.

I would hope that you would know that you know how to do this. I

Thx for all the info guy, i do appreciate it :thumbup:.
Pity i didn't know what i know now with the servo horns, but i'm sure some others will read the info and make use of it.

Anyway my horns "should" be here in the morning so heres another question. do i need to file the two bump things for the Elevator-servo or use one of the "rubber glove" things it comes with ?

Thx

Yes trim them off and don't use "rubber glove" things as it will throw off your geometry.

[jamesotron99]

Yes trim them off and don't use "rubber glove" things as it will throw off your geometry.

I use the rubber grommets on mine, but not the metal sleeves (because the 2.9 screws don't fit inside them).

Hasn't affected my geometry in the slightest (at least that I can tell).

[OICU812]

Yea as long as they all have the grommets then you should be ok, however if you did isolate it to one servo yes it would and could cause a small bit of interaction. Personal preference I believe in most cases. On my E Helis I do not run any grommets, that being my preference. ;)

[ShuNut]

Thx again for the info Guys.

I decided to just cut the bump things off. The hardest pt of the servo install was finding some washers, Mikado could have thrown a few in the kits. I managed to get some from a hardware store and got the smallest ones they had which just about did the job, a bit too big really but workable.

QUESTION..................................
To get all the servos moving correctly i not only had to reverse 2 servos (which seems normal) but also had to change the Ali +plus setting to -minus, without doing this every thing was ok apart from roll, which was rolling the wrong way.

So what i'm asking is: Is it normal to have to use servo reversing and reversing one of the swash settings ?

I thought you only needed to do one of the other, i'm sure i've done nothing wrong but would like the sound advise of You Fine Gentlemen Of Heli Freaks.

Thx

[Funflyer]

Pretty sure that's normal. I think I had to do the same thing on my 450.

[Mercuriell]

As long as it all ends up going in the right direction it doesn't matter which servos are reversed of if any or all of the swash mix is + or -

[jamesotron99]

Bingo. If it flies then you probably did it right.

[ShuNut]

Thx for All the help and tips so far Guys, I Do Appreciate it :thumbup

I'm now setting up the tail & would like a few tips & info.

I'm only used to setting up a 450 tail & 401 gyro, on this bird i have the BLS251 & Spartan gyro, do i set it up the same way as the 450 ?

Asin
1: Get servo horn @ 90......... Mechanically its off, can i use subtrim to get it center ?
2: Get the slider in the middle of tail shaft In Rate Mode... does this give 0 degrees on tail or a few degrees ?
3: Check for reversing, set end points etc.

Is this the right way to set it up ?

Thx

1) have you tried rotating the Futaba servo horn to different positions - the splines on Futaba are offset and it's rare not to be able to get a passable 90° position - subtrim on rudder generally not thought to be ideal.
2) Mikado recommend 14mm for tail servo arm length on my 500 and 600 I used the middle hole on the 6 arm wheel which is a little less. Set the links to give mid travel at mid stick in rate mode - it doesn;t have to be exactly neutral tail with a HH gyro but it works out to be pretty close.
3) For the Spartan check out Bob's setup vids (http://www.helifreak.com/showpost.php?p=418697&postcount=1)- in brief check that your tail servo is moving in correct direction then power up in HH mode and just after pwering on flick into HH mode and back a few times - the servo 'chatters' to let you know the gyro is in setup mode - push the stick left - that sets gyro direction. Flick into HH mode and back then set one limit of travel with the rudder tx stick, flick RM/HH again and set the other limit of travel then flick RM/HH again and you're done - dead easy - almost prug and pray !

[ShuNut]

Thx for the info Mercuriell.

Naa i cant get it at 90 by rotating the horn, closest i can get is not too much off see pic and i would need about 17 clicks to get 90. But from your advice i've been reading up on that thread and ur right in that i shouldn't use any subtrim.......... so i wont.

So to be clear IF i set the tail slider on shaft at center ill be good to go but only in HH mode, if i want to use Rate mode i'd need to set the tail slider on shaft so i have 8-degrees.
Is this correct ?

[ShuNut]

Ok, heres how it looks when i get as close to 90 as i can.
Is this ok ? also what about the tail slider is that ok, this is with the rod ends epoxyed all the way into the rod with no adjustments.

I am used to setting up the tail on the 450 (many many crashes) but getting 90 without subrim was always no problem...................... Soooooooooooooooooooo...
Am i good to go the way it is ? The tail slider looks like it could do with moving to the right a bit but that would mean screwing "IN" the rod ends but they are already all the way in.

Thx

Is your servo over extending, i know on mine it doesn't need to move to far to go full left or full right, I might make a movie and show you.

Jase

[ShuNut]

Thx but No i haven't even set up the end points etc as yet, i'm trying to find out if my servo horn is ok where it is in the pic, asin NOT @ 90, and if my slider on the shaft is ok where it is as i can not shorten the rod ends to move the slider to exact centre.

[Mercuriell]

WHy don't you use a FUtaba wheel ? - the Mik ones are great on cyclic but not necessary for the rudder servo - I bet you could get a lot closer than that with say the Fut 6 spoke !

[ShuNut]

Thx Mercuriell :thumbup: You saved me again.

I totally forgot i had other servo horns, 1st i thought i HAD to use the Mik horn on the tail servo, then after reading a few pages of that Spartan thread i did realize i could use other horns but thought i only had the too-small wheels that are fitted to the futabas.

Dug out my boxes and found the 6 spoke that u spoke of (Ha :P) and its now fine, very nearly bang on 90 and i could then adjust my tail slider correctly.

Shamooooon ! :...:

Hey Guys

Just wondering if you can help me find out WHY I have so many bits left over from the build (see pic).
I know a few bits like the longs threaded bar for the frame bolts, and the bits in the bag are "canopy bumpers yes "? but what about the rest of the bits, all them screws nuts & bolts ?

I did use nylon bolts for the LG so i can see i'd have 4 spare bolts for that (although i only see 3)

Have i messed up somewhere, it all looks ok

Confused here :confused:

There are no instructions for installing the bumpers, but see this (http://www.helifreak.com/showthread.php?t=65807) thread for some advice on such.
