Here is a better shot of the mech brakes.

Hey, my build has come to the electrics install. I have three motors to choose from, maybe you can help me. I have castle's 1800kv motors, in 1518 AND 1512 size. Then, I have a NEU 1509 2400kv....

I have a 4s 3300mah 35C battery to use for a ultra-lightweight setup with the 1509 and modded mamba max/MMPro. This was to go in my Hyper Mini STe, but I suddenly wanted to try it in the LRP buggy.

What is the weight of the LRP/Z-car in relation to other 1/8 buggies. Is it among the lightest, or not?

Of course the castle 1518 with 6s and MMM would be VERY much fun:lol: BUT it will make it harder to find room for the mec brakes, and I am going to use them.

What would you guys recomend? Thanks.

I sold my first Z-Car (the one pictured above) but I am putting togther a second one. In my first buggy I ran a 1512 but it gets really hot here in the summer and heat was always an issue. So I switched to a bigger 1515 motor and it ran cool. For my second Z-Car buggy I am going to try the 1512 again (on 4s) and maybe a 1509 on 3s. On my first Z-Car I had the brake servo mounted on an extended center diff mount top plate (along with the esc) so it was completely out of the way of the battery/motor. I think I may run this buggy without the mech brakes and go with a lighter setup using the 1509 on 3s. I also have a Losi 8ight 2.0 and Hot Bodies D8 (both Tekno brushless conversions) and both run big motors (1515) and mech brakes and I want to compare them to a lighter buggy (Z-Car) using motor brakes for comparison.

I ended up with MMPro and castle/neu 1512 1800kv, on 5s with mec brakes front and rear. I am going to try the 1518 too, just not at first:yes:

The mount and tray is RCM, and I have moved the rear brace over to the left side with some modding, this way I have no problems with small pinions. I am using the springs from a hyper 8,5 PRO with the ofna upper spring retainer over the stock spring cup(or what its name is), as adviced in this thread. Much better damping/spring ratio IMO.

If the snow will melt and evaporate, maybe one day I can drive this car too:whip:

Here are some low quality pics(long overdue, sorry), of the car almost finished. The wiring will be dealt with, I assure you:lol:

That is my little schnauser drinking in the background:tongue:

The snow finally melted, and I got to try my new LRP buggy on a football-field with short astroturf. It was just amazing, I loved the way it drove, lots of steering on and of power, which I like. I got about 15mins out of the 5s 30C 3200mah battery, which is just fine IMO. :yipi:

When LVC hit the temps were all under 100f, perfect. :party:

Only problem so far, the centre diff is leaking badly from the hole that has a set screw to seal it. I can guess all three diffs must be rebuilt with silicone/glue to seal the threads of the set-screw. Not fun, but had I read up before the build I'd never have this problem. Its well known.

I got the differentials leak free with new oils(f-c-r , 5000-10.000-3000). I also changed to a xcellorin 1700kv motor, since the color is the same as the alu on the rest of the car:lol: Looks great.

This time I went to a gravel/sand parking lot near the woods, which was empty just as I hoped. The LRP buggy worked so well, and looked bad ass with my newly painted shell:yipi:(I took "before pics" so you can se it before any wear and tear). Again the performance was awesome, this is now my favourite buggy by far. Lots of steering on and off power:yes:

IMO the xcellorin 1700kv motor is a great motor on 5s(probably 6s too), lots of low end power and top speed was great in this light buggy.

I will post pics when I get home in a couple of days.

I have always heard the Xcelorin motors are pretty solid, should be a good setup. I think a lot of people just don't consider them because the ESCs have kind of a bad reputation.

I have a Z-CAR ZMXB-8 here which I have to convert to brushless for my team racer. It is the same as the LRP buggy. I already have the RC Monster mount for it. He will be running 2 - 2S 5000Mah Li-Po's. Do you think the Mamba Max 2200 would be a good setup? I am fairly new at this brushless stuff because I run Nitro. I would use the Xceleron set-up, but everything is out of stock at Horizon.
For the Mechanical brakes, I see how you set it up, but how is it wired in? Does it connect to the receiver for the same channel as the ESC? Any help with this would be appreciated.

What diff oils do you other z-car owners use, I can't get it right with this buggy:no:

I think my racer runs 5, 3 , and 1. He does very well with this setup, but he is also very smooth with the throttle.

We don't have to do the conversions anymore. Z-Car is finally releasing their Brushless Pro kit. I have some on order and can't wait to build one and try it out.
