View Full Version : Noobe.Servo and Head Q`s

Only my 2nd post guys and got the EP200se after a Contra XRB.I know this is a bad choice but i have no outdoor facility to fly yet but i have a large indoor space,hence the EP for now.
I got the EP used but as new with all good elecs.
Luckily i noticed the post here for the new manual to help build.
I have 2 probs/Q`s for now,More to come :YeaBaby:.
When i put the hs45`s in the frame the linkage rods are vertical looking at the side of heli,using middle hole of horn.BUT looking along the heli the linkage rods are way of vertical,I have tried putting servo inside and outside of frame but cannot get the links anywhere upright.
I had no 2mmx10 bolts to connect main grips to hub.I have bolts that size but want to ask a Q.The hub is threaded to take the bolt but not threaded all way through,it bottoms out.How is it meant to work,should the bolt bottom out Just as the grip as no play OR bolt tightens fully gainst grip bearings before it bottoms out?Is the second method bad on bearings or makes them tight.
Sorry if these Q`s are basic.

If you mount the ball on the inside of the servo arm the link will be very near vertical. The blade grip bolts should have a nylock nut; there are no threads in the grip itself.

Use the correct Gaui screws ( part No 832010 ) for fixing the blade grips to the head. They are very soft, and limit any other damage, in the event of a blade strike

You need to order some of the screws. The Gaui made screws will not bottom out. The correct screws are very important because the wrong size screws will cause major problems, not to mention safety issues. Just about any 2mmX10 screws/bolts will work but the Gaui ones are soft and tend to bend/break in a crash and may save other things from breaking.
ReadyHeli sells hard bolts and the Gaui one's too.

Sorry about that guys.I was using a small laptop and was not really paying attention.
I thought using all capitals was shouting?
I thought using large text only upset people with printers:YeaBaby:

Your M2 x10 screws shouldn't bottom out. Make sure you have all bearings, spacers, and o-rings installed.

I need to get some of these... but that can wait. Do i remember right and that Armour Nut will need to do some 'Ball Grinding' (Ouch!!) on the 45s to make them clear the servo case, when mounted on the inside of the arm?

That is on the elevator servo. If you grind your balls on the aileron and pitch servo it will take the linkage farther from 90 degrees and it won't feel good either.

Thanks for the advice on servo linkages.
I had a quick look and on my heli if i mount balls on inside of servo horn the nearest i can is apx 1/4in of vertical at servo using the hs45`s.I have seen some pictures here and the linkages seem vertical,more so than mine.Are you guys using any spacer`s.
The 2mmx10 bolts i have are philips/pozi head and seem to be soft.They do not bottom out and once tightened thr grip is smooth with no play.Can someone give me the length of the threaded portion of the Gaui bolt please.I will take a chance and use these as they seem soft ,cut with pliers easy,not a good steel bolt.Might be nickle.

They are 10mm long. Are your links sloping inwards or outwards? In other words, do the links need to be moved closer into the center of the Heli or outwards, to reach vertical? Are the tabs on the servos, on the inside or outside of the frame? A picture helps if you can upload one.

I hope you have all the shims, spacers, bearings, washers, etc, in the blade grips properly. They are the parts I had to yell for help on. Have you visited the "build, repair" sites yet? If those blades are loose on the feathering shaft like I think you asked, something or somebody is gonna get hurt.:shock:

I am going to try and get some pictures to post of the linkage rods.
Mine are way off for sure looking down along the frame/boom.

Armour,
Here are pictures of my set up. The balls are kit stock with molded standoff. On the elevator servo arm I ground off the base to give good alignment and servo body clearance.

Greencello,
Thanks for the photo`s.
The second photo looking down the heli shows your linkages more vertical than mine.
I have the same frame and servo`s and swash,also the ball at servo has the stand off.
I am just going to check to see if i have balls with stand off`s on the swash like yours.
Something i have noticed and do not know if this is common or just on mine is that, on the front servo`s when i slide my sevro`s into the slot when the bottom of servo gets to the other side of frame it touchsit.It has to lift at a slight angle.I was going to file the frame down slightly BUT at this area at the very top of frame there is very little material there to start with.Both frame sides are at same height and paralel.

Make sure your servo case is completely together and not out of square.

All servo`s perfect.

I'm still not sure what you mean by not vertical? Please describe the orientation and which servos you're having problems with.
If you mean the Elevator servo, when looking down the boom, then yes you do need spacers to get it vertical... see photo.
If you are talking about pitch/aileron servo then that's a little more strange to expalin why yours are out. Is the servo arm on all the way? have you got the ball in the right hole on the arm? have you tried moving the servos inside the frame... see photo?

GreenCello, whats with the black canopy mounts and mainshaft boom in black/plastic.. is this and early 200?

Stoat,
I used plastic Trex canopy mounts. My kit was purchased in early June so unless it was on the shelf a long time I assumed it was up to date. The main shaft bearing blocks and the tail boom block are plastic.

Strange... where did you purchase it?? I'm sure they should all be coming with CNC central booms since the start of the year. I have 2 spare frames.. the one on the Right is from the end of Feb, the Left one form the start of April, note the change in standard Canopy Mounts... Ignore the CNC swash guide its an upgrade.

Well I guess I got what I paid for. I got the kit from A main Hobbies listed as Gaui 200 Pro Carbon.
Must have been some old stock. Bummer, but it flies great.

Are the plastic canopy mounts not a good idea? I read on other posts people are swapping the aluminum ones for plastic to prevent cracking your CF frame if (when) you crash nose first since they give and the aluminum ones don't?

Or here's another great idea, posted by WBFair, of adding a center tube...
"Keep in mind that this tube is one of the longer ones at 4x22mm as apposed to the 3.5x19.7mm that well all seem to have extra of but if you don't have one there really easy and cheap to get via the Align Aluminum Tube kit PN: HS1188T"

Am I seeing things, or does greencello's plastic one have this same setup?
