Homemade brushless baja - RC-Monster Forums

gyn77 · **Homemade brushless baja -** 09.01.2009, 05:10 AM

After converted a from nitro to brushless real Baja and sold it cause need of money, I decided enjoy making an homemade baja starting from my Savage and inspiring myself with two baja project founded in this forum.

I started the project from savage, making an homemade chassis as in photo:

I used my Neumotor 1521/1Y (1577 rpm/v) and a mamba monster max with
6s zippy lipo.

I bought the real baja wheels, but the seller sent me wrongly 4 rear tires, so I'm waiting for 2 front tires yet.

So in my summer holiday I completed my homemade baja with bowtie MTS savage wheels for the firsts running tests.
I decided to make it 4wd also.

This is a small video:

I'm really satisfied from it, it runs very fast and motor temperature was 67 C° at max on grass/dirt/stones terrain, battery autonomy was great similar with savage (about 20-25 minutes with zippy 5000 mah 20c).
In the future I will test it with eagle tree system for better relevations data.

thats........Awsome mate ,what motor you got in it?

gyn77 · 09.01.2009, 05:26 AM

It is a Neumotor 1521/1Y (1577 rpm/v)

I used Neumotor 1521/1Y (1577 rpm/v) and a Mamba Monster with 2 x 3s zippy lipo 5000mah.
The brake is the esc brake.

I really like it! Awesome!

You Sir are my hero! I love it! One of the top 20 builds on this forum IMHO.

The baja wheels have a 24mm hex. The savage 5t has not been released here yet, and I am not sure if it will be released. HPI made 24mm hexes to allow the use of the baja beadlocks on the savage, but I do not think they are available yet either. Best thing I can think to do would be to get the easily available 23mm hex adapters for the savage and wrap some .5mm shim stock around the hex to bring the overall diameter to 24mm, use some epoxy to hold that stock to the 23mm hex and you would have a sturdy 24mm hex. I will have to weigh the beadlock/tire combo that I planned to use on my stretch savage project. I plan to use a std MT size beadlock (such as the popular maxximizer beadlock) and moab xl tires. I will have to cut a section out of the tire and glue it together to get the inside diameter to match the diameter of a MT wheel (since the moab xl tires are designed to go on a 40 series wheel). I am doing this cause I like the width of the moab xl, and want a tire with a taller sidewall (and taller overall height) than a std M tire can offer. Plus the ratio of wheel diameter to sidewall height will look more like a corr truck's stock tires (as I plan to put the 5t body I have on this creation).

Anyways, I really like your truck gyn77. It gives me more desire to finish my various large scale projects!

I also thought to buy 23mm hex, but the problem was that I cannot replace the same Front Width 18.1" (460mm) and Rear Width 18.9" (480mm) of baja because savage braces are not so long as baja braces.
So I thought homemade adaptor was the best way.

Simple and effective at its best. Many engineers should follow the "Simple and effective" theory. A lot of the good set ups I've seen are simple. Good job.

Thank you Lutach!

Very cool project.

Here a photo of my baja with baja wheels and tires. It is juge!

Now I am thinking putting 2 super light alluminum carters instead of carbon one because I already have light alluminum sheets at home. The effect will be similar this:

Good point, I was looking for equal track width on my 5t so that should not be an issue.
