Needless to say I've ended up achieving very little progress today
I got everything going except for the co-axial MG (I buzzed out the connection so I know that side of things was at least thats OK). In the end it turned out to be apolarity issue.

The following is a progress shots of the refined mark II version of the slip ring cradle and attempts at making the turret attachment more robust.
However now to the loss column, I extended the turret rotation motor and head light wiring so that I can move the small sub connector board from the underside of the hull top to the chassis and all seemed to be fine, yet when I went to turn the tank on the head lights did not flash, just in case it was a simple OC of the light circuit I tried hitting the start key anyway but still nothing.
I checked the continuity of both the extended circuits and the buzz out OK, so the problem is not there, swapped out the battery but still no good, so I am currently at a loss to work out whats wrong

It's very early days so late at all, on my copy the ring as is the entire rear portion af the turret underside is unpainted and there is a very light lubrication of some sort present.
I be removing the turret (again) to do some modding over the weekend and will also take a look at the rotation gear to see what state it is in.

Surprisingly it more or less worked, in fact it is the location of the small sub-board connectors next to the turret drive and the limited length of the turret drive cable that prevent this sub-boards easy relocation that poses the biggest tangle / interference hazard issues.

However at the same time I want to try and solve the basic mechanical side of things, as I see it in its the fundamental mechanical issue with the slip ring of the 360° kit is it’s lack total lack of any form of anchoring. So I’ve got hold of some scrap soft aluminium from work that I am going to try and prototype into a cradle to suspend from underneath the gear ring of the turret, which hopefully will give the slip-ring a fixed and centred rotation point. I also intended to try anchor the other end to the chassis to further promote better rotation.
Once I get the rough dimensions sorted I can them make a more refined cradle, I may even go as far as then design a 3D model in CAD, in the hope that I may get access to 3D printer in the future.

Where do I start??? First up make your own 360 wiring harnesses as those ones may not have enough wires. Search eBay for 'slip ring' and get one with enough wires.
The reason you have turret rotation problems is because there is NO proportional control with the RX18. It is either ON/OFF at full speed. The motors and design are OK it is the electrics that are the problem (QUE - friendly reminder of Pfish's MANTRA - upgrade electrics BEFORE anything else)
When you have the proper hobby 2.4 ghz system you can use a GEKO to control the turret this will give you precise control with the stock mechanics. You must have seen all of the GEKO vids on the RCTA youtube channel. PLUS with GEKO you can add a GA250 gyro for turret lock/stabilization - again videos here on forum and youtube.
Now because it is just you , Graham & Ian monitoring this post I'll sneak you guys a head up. Most if not all of my delay in producing a complete system has been sound. I did not want a system that was not capable of producing polyphonic (more than one sound at a time) sound at anything less than CD quality. Finally a couple of excellent sound options have become available and I have been able to move forward with Taipan 2014. But this new sound option is fan-freakin-tastic. How does 12-14 sounds at once at CD quality with micro SD card for file storage sound grab you???? Now the good part - sub $50 (sound card only)
In production in China RIGHT NOW is the Taipan 2014 proto board:
taipan2014.jpg
The Basics:
Sound system - a shield board that fits on top of Taipan 2014 - details as above (Separate board)
Drive system - 2 x 30Amp STI motor controllers
Turret and Gun - own dedicated microprocessor and motor control
IR Battle - MAKO2 (allowing for servo recoil and battle stats)
Rear and head lights
Dual Machine guns (gone overboard here giving the mgs their OWN microprocessor for control - this will allow for imitating any mg type or flak cannons in the future)
As stated this is a proto board 10 get produced and I only need 2 or 3
Just something to bear in mind.
Cheers
KG
