First check the tension of the synchromesh belt - press one side it ought to deflect to half way across the gap.

If you look at the boom holder under the gyro plate, you will find two machine screws and lock-nuts.
looking from above, in front of the gyro plate there are two very small self-tapper screws undo them and the gyro plate will slide back on the boom. This will permit access to the boom clamping machine screw lock nuts

Slacken-off the machine screws and that will enable you to ease the boom tube in to ease-off the tension on the synchromesh belt

Hi Burgess, Thanks for your Reply, so what your saying tension is adjusted from the boom clamp on heli, not from the tail clamp, i'll slacken of a touch see if that resolves my problem, once again thanks for your feed back.

Hi,
first: my last post -erratum- (should have got my 60#B out to look at) there are three machine screws and nuts in the boom holder to clamp the boom, not two, my mistake.

The design of the boom holder of the Hiko 400, is based on the 60#B boom holder and synchromesh belt adjustment on all walkeras with synchromesh belts is usually effected by fore and aft movement of the boom in the boom holder.

In fact, the Hiko 400 is designated 60#D

Compare the 60#B and the Hiko 400 boom holders
http://www.helipal.com/hm-60b-b--z-067-tail-boom-rod-holder.html
with the Hiko 400
http://www.helipal.com/hm-hiko400-z-32-tail-boom-holder.html

However, on the Hiko 400, Walkera have diverged from their usual tail box design which is held fast to the boom pipe with a long machine screw that passes right through the assembly, consequently no adjustment possible there.

With the number of others reporting the same problem as the one you have experienced with your Hiko 400 and they have experienced difficulties releasing the boom in the boom clamp; Walkera may-have diverged from the usual system for belt tension adjustment and effect adjustment by moving the tail-box aft on the boom.

On my 60#B, the belt has never derailed from the flanged guide rollers; they are free to move up and down on their pillars.

There are good photos on this site...
http://www.rchelicopterselect.com/walkera-hiko-400-6-channel-rc-helicopter.html

Looking at the photo -that shows the belt drive and guide rollers- in this photo, the belt is low in the rollers.

Strip down the main frame and adjust the boom-holder to better aline with the synchromesh gear, is one alternative.

Or simply placing shim washer 1mm thickness behind radial bearings of the guide rollers, would lower the rollers, to provide running clearance between the belt-edge and roller flanges.

Hi Burgess, When purchased i Thought belt was over tight Don't know if the belt being so tight has caused the problem putting the guide to run out of true, i'll post a Pic for your thoughts on it. im also waiting reply from supplier as this is new, Like looking at it but would rather be flying it.
Thanks again

Hi,
From way the guide wheel is listing, it looks as though the problem is with the bearing inside the guide wheel.
Either disassemble the bottom half of the frame and main gear to give access to the belt-guide wheel; or disconnect the boom holder from the frame so as to permit access to the guide wheels.

Question: does the boom and the skid pipes have a smooth chrome-like finish?

Hi Burgess, ref to your question, the skids are chrome finish & the boom is like a grey metel finish.

Hi, how did you up-load the photo?

I tried to upload a photo of my 60#B drive gear but ran into a problem and received this:-

General error dialogue box

Image could not be uploaded.
DEBUG MODE
Line : 143
File : uploadpic.php

and underneath - phpBB - link which took me to http://www.phpbb.com/ website.
Do we have to download and install pbpbb software in order to upload photographs into this forum?

Hi Burgess,

I just did a test upload of an image and the system seems to be working fine. I've created a tutorial on how to upload images a while back, you can find it here.

Hope that helps Smile

Yeah, the Hiko 400 is in fact the last version of the 60 it’s the 60#D,
so the HM-60B(B)-Z-19 Pully Set with bearings will probably fit straight onto the Hiko.

You can obtain the 60B pully set from RCMODS.co.uk for £3.56 pluss postage.

Hey Astraman
Have you sorted out that guide roller on your Hiko 400 yet?

If you drop the lower frame off and unscrew the M2 machine screw holding the 2x5x2.5mm radial bearing inside the guide roller, you will find that it has probably been put in cockeyed.
You might be able to get the screw to recut the thread so that the screw is alined properly and so too the guide roller.
If not, a new boom holder from Helipal is only £2.35 plus p&p.
