Capo 1582-2 Tatra T815-7 8x8 and Cross MC8 Man Kat 1 8x8
 

This will be an ongoing journal of these 2 models I bought recently. I will try and keep things current as I have some rather ambitious plans for both. For starters, size comparison between the capo and cross 8x8's. And a shot of the scale motor build of the capo.

Tore into the drive train a little bit and boy im glad i did. Not only was nothing greased, but most of the screws i have taken out were loose. And a couple were backed out completely

Started swapping out socket head screws for scale hardware

Heres something a little unnerving. The only thing holding the cab onto the chassis is 4- m2x5 screws.
http://tapatalk.imageshack.com/v2/14...21cfecefb0.jpg
Lots of room in the back of the cab for electronics
http://tapatalk.imageshack.com/v2/14...a6821217fd.jpg
Another area of concern. The cab mounts to the front bumper/skid. The bumper/skid mounts to the chassis with yup... 4 m2x5 screws. They seem to have some play in them. I will be putting longer screws in at the bare minimum. Hopefully they wont need to be drilled and tapped with a bigger size down the road
http://tapatalk.imageshack.com/v2/14...79e61cfc28.jpg
The entire bed is only held on with 4 m3 screws as well. Not much i can do here as the hole aren't tapped very deep. i just hope they hold up.

Another thing im not fond of, under compression and full lock the front wheels are going to be rubbing the shocks pretty bad. Uncompressed

This allows access to the standard m4 size nut that holds the wheel on
I also noticed that on the rear wheels the nut bottoms out on the shaft before the rim. Leaving the wheel a little loose. I will have to shim it.

One of the front wheels was really wobbly. Found out why the screws were loose and one backed out all together

Diff locked.
http://tapatalk.imageshack.com/v2/14...6affd9275b.jpg
This diff scares me. For how heavy this truck is theres such a tiny bit of mesh where these planetary gears touch... I cant see this being very strong

This was fun to put back together. I had to grease the shift fork, but not so much that grease squeezed into the hole that needed to be thread locked. Then i had to hold the parts inside the tube lined up to the hole and try to thread the link mount into the fork, while being careful not to loose the bushing ...

Re: Capo 1582-2 Tatra T815-7 8x8 and Cross MC8 Man Kat 1 8x8
 

so theres 4-m3 tapped holes in the bottom of each axle case. Im not sure why they are there, other then maybe for adjusting the the ride height lower, or maybe skid plates...
http://tapatalk.imageshack.com/v2/14...0187dc1b1a.jpg
I filled them with some screws to keep dirt out
http://tapatalk.imageshack.com/v2/14...d8060d803c.jpg
I changed over to tamiya ceramic grease. I was worried about the sticky black grease not getting to the areas where the planetary's shafts etc. spin and not being lubed. The tamiya grease is alot lighter and flows a bit into all areas from what ive seen.
http://tapatalk.imageshack.com/v2/14...6db7c2d209.jpg
Another area where theres a big issue is in the front steering geometry. Everything works dandy with the steering until you add compression on the front axle. At which point the steering arms hit on the top of the axle. I played around with some offset rod ends I had laying around, and it seems they will suffice to remedy the problem. All i had was short ones, I have some longer ones ordered ill replace them when they come in. Too bad they're plastic.... I cant find any metal ones. This is the steering angle at full lock.
http://tapatalk.imageshack.com/v2/14...e886ad802f.jpg
This is as far as it turns before it binds under full compression

Cracked open the 2 speed transfer case
http://tapatalk.imageshack.com/v2/14...dcbb4dfe47.jpg
Gave it a good dose of grease
http://tapatalk.imageshack.com/v2/14...2486e2792a.jpg
When i cracked open the 3rd axle housing. I noticed one of the bearings had fallen out of it seat. Theres nothing to hold it in place.
http://tapatalk.imageshack.com/v2/14...f6d4a3c6b2.jpg
Looking closely at it, the bearing is actually 2 bearings pressed together to make one. Kind of odd.
http://tapatalk.imageshack.com/v2/14...056e49da30.jpg
I shimmed it with some washers to keep it seated.
http://tapatalk.imageshack.com/v2/14...d782354977.jpg
This is where it sits at now. Its proving to take quite alot of time to swap out the many many screws.

Re: Capo 1582-2 Tatra T815-7 8x8 and Cross MC8 Man Kat 1 8x8
 

Started swapping out the fender bolts, i may or may not keep the washers. Im undecided so far.
http://tapatalk.imageshack.com/v2/14...11736b62fc.jpg
Im having a hard time deciding on paint color... Leaning towards nato green...
Im definitely open to suggestions...
http://tapatalk.imageshack.com/v2/14...42a7ed735a.jpg
The rear axles halves are pretty much identical for all 4. There are m3 holes on the sides that don't have the coil overs. I figured id fill them with some grub screws to keep the dirt out.

Fuel tank removed. I want to fab up some sort of skid plate for it so i dont end up tearing it off.
http://tapatalk.imageshack.com/v2/14...ae4d7b6d5f.jpg
Changed the m2 screws that hold the front bumper on. I put longer ones in as this is a critical area as it holds the entire cab on!

Re: Capo 1582-2 Tatra T815-7 8x8 and Cross MC8 Man Kat 1 8x8
 

2-m2.5 screws fastening each cab hinge to the bumper. With only about 3 to 4 mm of thread actually holding the hinges on, i was concerned about them being strong enough. So i tapped them all the way through and used longer scale hardware.
http://tapatalk.imageshack.com/v2/14...441e96e642.jpg
This is what it looked like from the front prior to tapping

http://tapatalk.imageshack.com/v2/14...d3aa797bbc.jpg
http://tapatalk.imageshack.com/v2/14...638aaa8ac2.jpg
Offset link ends added. This stops them from hitting the axle under compression, i just wish i could find some metal ones.
http://tapatalk.imageshack.com/v2/14...d7ed2bf537.jpg
Full lock and compression, and no binding! Tomorrow I'll replace the styrene with aluminum and make them look presentable.

Wow,for the amount of money they charge,you would expect better job.

Re: Capo 1582-2 Tatra T815-7 8x8 and Cross MC8 Man Kat 1 8x8
 

Well it cost a lot of money to manufacture something like this. The machine work is just phenomenal on this rig. I imagine they lifted prints off the full scale counterpart as a starting point in designing this truck. In which case there is always going to be issues when scaling something down. For instance, the 1 to 1 Tatra uses air bag springs positioned on top of the axles out of the way of things. Not such an easy thing to scale down. These don't need the distance of a coil over to work. Having to use coil overs means Capo had to decide to either mount them on top or on the sides of the axles. Personally I'm glad they chose the sides, as it keeps the springs lower on the chassis and not visible, this would take away from the scale appearance somewhat, and possibly hinder bed heights. I can live with the springs being seen over the #1 axle though. Sacrificing turning radius in favor of hidden springs is not something I want in my truck. I'm ok with having to iron out a few wrinkles in it's design. Going through a rig bolt by bolt and fixing/modding what needs attention is half the fun of this hobby.

Re: Capo 1582-2 Tatra T815-7 8x8 and Cross MC8 Man Kat 1 8x8
 

WOW! Great machine,but a lot of tinkering to get it perfect. Where can I get those scale screws? I kind of stepped aside from my 6x6 build but will get back at it now.

Re: Capo 1582-2 Tatra T815-7 8x8 and Cross MC8 Man Kat 1 8x8
 

Thanks! You can find the screws at RC4WD and Locked Up Rc. Personally I like the locked up screws better. They seem to have crisper edges all the way around and are true round stock. Unlike the m3 versions rc4wd carries, they are kind of triangular. I tend to buy from both companies tho as not one company provides all sizes/colors.

Re: Capo 1582-2 Tatra T815-7 8x8 and Cross MC8 Man Kat 1 8x8
 

Yes even the most expensive models require a bit of finesse to get right. It's not needed for most that purchase these higher end models but it's nice to see someone going through and making it right. I have always thought of these models as high end and it's just fitting to finish them off proper :). Nice to see you keeping the intended precision work matched to the quality of model. Keep the post coming. I've always wanted one of these but I can't justify the price for my use, at least not yet :) so it's nice to see your posts. When she is complete and proper you got to put her in the ruff and video!!

Re: Capo 1582-2 Tatra T815-7 8x8 and Cross MC8 Man Kat 1 8x8
 

Thanks, its a fun rig. I cant wait to have it out on the trails/rocks. There will definitely be many pics/videos when the time comes!

Re: Capo 1582-2 Tatra T815-7 8x8 and Cross MC8 Man Kat 1 8x8
 

Well after testing a few different paint colors I had laying around, Ive decided to try and match the darker green of Capo's anodizing. Ive ordered some darker greens in hopes of getting a closer match. Im thinking black green might be the ticket. In the pic is nato green on the left, olive green on right, and the factory anodizing color on the bottom.

Looks great. Definitely a shame you had to do all this work. If they leave the drive line parts that unfinished I wonder why they even take the time to provide them assembled. The scale hardware really looks awesome as well :drool:

Re: Capo 1582-2 Tatra T815-7 8x8 and Cross MC8 Man Kat 1 8x8
 

Great thread on the 'rebuild' :eek: Glad that I didn't splurge and buy the Capo. The Cross-RC is enough of a challenge to keep running. I have broken 2 steering knuckles already with no real off-roading. 1 broke during assembly and the other broke at Indy during its maiden run. I had ordered more steering knuckles after reading a few build reports on the 8X8. Just glad that I had an unassembled 6X6 handy to get parts from. Noticed that they changed the type of plastic for the axles in the 6X6. Feels more like an engineered plastic rather than ABS in the 8X8.

Will keep watch to see what you say about the Cross-RC 8X8.

Re: Capo 1582-2 Tatra T815-7 8x8 and Cross MC8 Man Kat 1 8x8
 

Thanks. I cant wait to get some paint laid down over the chassis so it looks like a 1:1 military paint job! The driveline does concern me some. my biggest fear is the little brass planetary gears not holding up. They are going to need to handle some serious torque at times...

They need to do something with their axles. The material mine are made out of is a joke. surprisingly its the rear axles that are giving me the hard time not the front. But out of only 2 short runs, I've had to superglue the shattered cases together, and now the 3rd axles ring and pinion mesh is jumping teeth due to the horrible mesh. I ordered some Yota 2 axles to swap out. I just gota figure out how I'm going to mount them. That and find some time to do it.
