I received my CRT.5 Pro but I'm a bit confused.

I thought the Pro kit had the extended chassis wich allows standard 1/10 servo's ?! Or I'm I wrong about this.

Either way I cannot fit my Ko2123 on it.

So whats next ? I probably have to buy RCM's extended chassis ?

I would also like to have the other part of the center diff mount in alu. Does Mike have this (I don't see it in the parts list) ?

The pro kit comes w/ the short chassis.
You have three options:
a) RCM extended
b) Ofna extended
c) BCE extended.
Choose which ever fits your needs best.

As for the center diff brace, you can ask mike to make one for you or get the ofna cnc center diff brace (comes in a pack of two). You can probably sell the other one to someone here.

I called up OFNA and then sent me the extended chassis kit for free - Alternatively I think impaktrc has it on sale for $35

I see RCM's chassis is also wider. How much wider is it compared to the stock one or compared to the Ofna extended one?

IF going for Mike's chassis (which I like alot) will the stock body fit ?

There are blue springs and white springs as options. Where do the standard springs (grey) fit. Is this hard/medium ?

I also have some Losi springs, which seem to fit. Anyone uses those ?

It's wide enough and a lot longer that I didn't think the stock body fit at all. I use the older Losi XXXT RTR body. It is a lot narrower than most 1/10 truck bodies, and fits the RCM chassi ver well. If you want to use the truggy wing with a 1/10 body then I cut the body off just behind the rear wheel wells.

The grey springs are the softest and stock. What springs you need will depend a lot on how you do your conversion. With bigger batts or a heavy L motor you may need white front and blue rear. With a lighter setup then the blue front & grey rear works good. Either way you will need to go with the stiffer pistons (I liked smaller 2 hole) and some stiffer oil.

I have a bunch of Losi springs too and they were a good bit softer than even the grey crt.5 spring.

At the moment I'm working on my CRT.5 and will post some pics soon.

In the meantime could someone instruct my in the relations brushless motors/Esc/Lipo's : Kv - Amps - ESC Amps - Lipo Amps.

I would like to understand all this. I know I can buy a motor based on what everyone else buys but I want to know what I'm doing.

Links to some info is also welcome.

Second, does anyone know of a buggy body that would fit a CRT ?
Maybe with some mods. I kinda like the look of a buggy body.

Any idea when the RCM chassis will be available again?

I'd start with the basics:

So now I'm thinking about the Ammo 3300kv.

Is it comparable or is it of less quality ?

I ran a 2600 on 2s on my son's - He's only 5 so I didn't need it crazy fast... worked fine....

Less quality though as you'd expect $40 motor vs a $110 motor

Since my rear diff was leaking, I decided to change the diff oil in all 3 diffs.

I'm going for 1K rear, 3K center and 3K front.

When I did the center and reassembled, I could hardly move the diff when holding both ends.

Is 3k too heavy or is there a problem. I reassembled it like said in the manual.

Lots of crt.5 guys run 3/3/1. There should be resistance, but not so stiff that it barely moves. Sounds like you have a mechanical issue. I've run as thick as 7000 in the center diff and it did not sound that stiff.

7K in the center is what I run, and its not that stiff. 3 shouldnt be hardly anything

I actually run 10K in mine, and using your hands, although there is resistance, it doesn't take much to turn each side of the diff in opposite directions. I think you may have some binding issue in the diff. I'd take it apart and make sure no gears are too close to each other or twisted or anything like that.

Well actually. As of version 2, I have a revo spec slipper, and revo spurs... Haha

But 7, to 10K is perfect for the .5 IMO
