thanks, since Im not allowed a real one I will stick with the little ones, problem with that is theres all these little things you can do to make them more life like, adding the sound changes everything , then theres lights and paint and ,and OMG this is getting out of control.
time to go and replace track motors and have a play, need to get my RC fix today.

cheers andy

Have just finnished installing the new track drive motors.
Found out why the tracks were jumping, I have sheared both pins; probaly due to driving small gravel and ignoring the bad sounds .
I didnt have 2mm by 35mm pins lying around .
measured a few pop rivets and they are a perfect fit.
1 battery flat , new motors work sweet and the pins are still going strong.

ok, finally bit the bullet and got another lowboy for the fleet.
was a stock standard rc4wd lowboy but it needed some upgrades.
all the fleet trailers are red so ,out with the spray can.
also cut up some 5mm MDF sheet and used a slitter blade in the grinder to make some fake planks.

Nice upgrades.

Nice pictures of the trailer and loader

[andyathome]

Thanks. Had to get a few while it was still all shiney..
now I need to try several batterys in the loader to see if my fix is going to be long term.
I can see why the bearing failed, just really bad clearance in the castings and a lot of loading.
I see this all the time at work on the cheaper electric motors that are fitted to some of the machines that get installed buy the bean counters.
they wonder why maintenance cost is so hi.
need I say more.
dose any one know if theze are the same axial setup as the armagedon dump trucks and do thay have the same issues.

loader up and running again, I think I've dislodged the sound module cable,
will run a few more batteries and sort as well check diffs.

put loader thru so rigorous testing ( just a bit of play time)
and all going well, battery flat again so the excavator needed a bit of a work out.
all going well.
don't know whats up with the mic on the lap top, I may adjust it with a hammer soon.

anyway heres a quick video of this mornings testing.

Mine dident come with the sound system but I will order down the road. Andy what did you use for shim material on your axles?
cool vids!!

[thebigo]

forgot to ask did you build that dozer as well?

[andyathome]

I borrowed a few small bits from work, brass shims 1.5 mm thick and super glued two pieces top and bottom in the main diff gear bearing housings , makes a nice sung fit, no way the bearings are going to move around now.
I measured the bearings and then the housing and found about 2.5mm of difference!
not exactly a precision casting, but all good now.

[andyathome]

yes, JUNK DOZER BUILD. its on here somewhere as well.

[thebigo]

Hey it don't look like junk to me, but I get what your saying. I need to just sit down and make some builds instead of buying all the time. Thanks Andy, I will keep in touch.

David

[andyathome]

no worries, I like to build most of my stuff but don't as yet have the skills or patience to do the fine detail some of the guys do on this forum.
one day maybe,

[andyathome]

Now a vacuam truck could come in handy.
As for playing inside. Punishable by death or so ive been told.
we bought a new house about a year ago. Wife got itchy feet I said big shed and that was my main want.
a week later she found a house with 4 acres of land and huge 4 bay shed .
go to the auction and we are the only bidders.
next minute we are moving.
I will suggest tha vacuam truck idea to help out with the house work. If you dont hear from me again you will know what happened.
cheers andy

[andyathome]

also need to point out that there is another use for the shed,
you cant just play with RC consturction modles all day, belive me Ive tried.
sometimes you need to make things. was lucky enough to get these two toys at a really good price, next to them is my paint box. have fitted a small fan heater at the bottom and cut a slot at top of box to let the heat out. makes painting all year round possible. welders and grinders on other side of shed so lathe and mill dont get covered in unwanted dust.
I plan one day to convert the mill into a CNC set up as ive seen it done on the net , looks easy enough but a little costly at the moment.

cheers andy
