Marcus, have a look at Steve's UC thread, there are a lot of information and some photos in there from me.

2025 ARMORTEK KIT SURVEY
Over the last few years we have brought out a whole series of kits as a direct result of your feedback - kits like the Pershing, JagdPanther, Hetzer, Leopard 2A4, and more recently the Sd Kfz 7, 88mm Flak 36 and the upcoming Challenger 2.
So, in keeping with what has become and annual tradition, here is your opportunity to once again influence our future production plans.
We have added in some "guide pricing" next to the names of the models. This is a rough estimate of the price at the current rates.
Thanks in advance for your input and we look forward to the results.
David's carrier build.

Re: David's carrier build.
Hi Phil,
Be careful you don't mix up part nos ER107 and ER105 top hull sides as the RHS side one (ER107) is about half an inch longer than the LHS one, I did and caused me a lot of extra work, luckily only on one model.

Re: David's carrier build.
So what do you guys think of the track warping, any good? Only any good for road work as in long sweeping bends.

Re: David's carrier build.
Hi Phil
I locked mine.
Going for a twin motor set up .
My late father drove a Universal carrier in WW2 and told me it was a pain in real life
often causing tracks to shed or break.
Regards
Derek

Hello David
Can you tell me the type of gearmotors or even the reference location that you are using on your UC?
Best regards
Markus

Re: David's carrier build.
We now have working floating disc brakes which are proportional. Around 1 to 1.5mm of free play is needed for the floating disc to work correctly. You need to find an extra 2mm for this type of friction material and a further 1.5mm to get this lot to fit, where and how you find this 3.5mm is up to you.
- Attachments
-
- Bonding your chosen friction material, in this case hd cork.
-
- The button heads need removing and the disc needs a surface finish.
-
- Taking just enough off the back of the pad.
-
- A 1mm recess to accept the fiction material.
-
- The friction material is now bonded in, this can be replaced when it's worn out which could be sometime. This has to be directly opposite the moving pad.
-
- The holes left are maybe going to work like the vented big brother. The disc finish is clean but not polished.
-
- Beautiful little brake pads

Re: David's carrier build.
Certainly looks like it has potential Phil. 
Loving the honest build.
Though the milling bit is annoying to anyone without a miller unless your going to be offering a special upgrade mod if this idea's a winner.
In my own mind I'd thought of a multi disk affair rather like a motor bike clutch.
I'm interested to see how your going to protect the servo, I've noted that some builders have burnt out servo's, so I'm expecting some sort of over pressure release system.
maybe?

Re: David's carrier build.
Hi Markus, the motors came from Hobbyking and are Trackstar brushed motor 550/21T, and the gearbox came from MFA Como Drills and is reference 942D271. You will have to remove the motor supplied with the gearbox and replace it with the trackstar motor, the pinion will also need to be removed from the supplied motor and fitted to the trackstar motor and the excess length of shaft in the trackstar motor cut off. It is advisable to mark the outside of the gearbox as ithe three sections making up the gearbox will only reassemble in one position.
Hope this is helpful.

Re: David's carrier build.
Be careful with that system Phil, I don't think you will get enough torque from the supplied servos to stop the wheels. Also you have to be careful in that you are suppling the the servos with 7.2.volts to obtain the 35kg and they burn out much quicker that a 5 volt supply. I know I burnt out 2 trying out the same system.
Dennis.

Re: David's carrier build.
Lots done this afternoon.
- Attachments
-
- The axle has been apart yet again to check all is ok and I'm very happy with it so far, those brakes work very well.
-
- These parts needed a pinch in the vice to get the holes to line up.
-
- Some small parts are miss numbered.
-
- Clean up time but not to bad.
-
-
- I seem to spend my life cutting down reduced heads.
-
-
- This grub screw needs grinding down to miss the through hole.
-
- Nice sunny day just right for paint and just right for celebrating the Queens 70yr reign, God bless you !
-
- For those that need to watch the pennies, that is ts28 can number three.
-
- Changing out the standard m3 for reduced heads once I'm happy with each stage.
-
- Bonding those return rollers, one tyre is way to big the other just a tad. So filling with the rubber cyno.
-
- I presume that this bogie swivels on the fixed shaft but it can't right now as the fixed shaft is to short.
-
-
- Don't get to excited David with this photo.
-
- It's not a full track! I need to spend a good day or more on those tracks.
-
- And now for a quick check of the alignment, track looks just fine although it's not a full track yet.
-
- All the road wheels look nice and straight

Re: David's carrier build.
I've been checking the finished pitch of the track against the sprocket pcd and looking through the various builds on the forum for as much information as possible to get an idea of the problem and solution .
This is what we have found, Mike the engineer and me the grunt.
The solution is.......?

- Attachments
-
- The tracks are looking good with a consistent pitch and it would not be cost effective to plug each hole and rebore, that would take hundreds of hours, so they stay as they are.
-
- The sprocket tooth pitch is 7.50
-
- Using Dave's nice and tight stainless pins we get 7.90 pitch
-
- If we use the split pins we get 8.10 (slack)
-
- When pulled tight we get 8.56, this will increase very quickly as it beds in.
-
- With the split pins 6 teeth are in mesh while number 7 and so on are now climbing out of mesh.
-
-
- When we use the stainless pins 13 teeth are in mesh at any one time the others are climbing out.
-
- Mike's journal recommendations.

Re: David's carrier build.
The solution is revised sprockets. I hope I don't get cancelled for suggesting this on behalf of the owners.
How about Kian offers two types of replacement sprockets, one set to match the split pin pcd ( pitch circle diameter ) and another set to match the stainless pin pcd?
I'm sure the guys would be happy to pay at cost for the parts, then everyone is happy?
