Nah... Unless you're a fan of the more exotic brushless setups, which in the context of racing, are not only unnecessary, but illegal, initial investments are a good deal less for brushless. One difference being that with brushless, the initial investment is the ONLY investment. With brushed, you need to maintain a running supply of brushes, springs, and motors... not to mention buying all the support equipment (and hauling it everywhere) .

I just bought a brushless setup for my XXX-CR (stock). I needed two things:

1. Sphere Comp 2007 Edition: $189
2. Novak 13.5 Brushless Motor: $77

Grand Total: $266 (any of the brushless combos by Novak and LRP will actually run $10 - $30 less)

Brushed Setup:

1. CO27 Motor x 2: $64
2. GTX ESC: $149
3. Lathe: $150

OOPS!

We're already over the cost of brushless (+$97), and we haven't even touched the spare brushes and springs. Also, with brushless, there's far less importance placed on batteries, so you could save a nice chunk of change on batts, too.

If we start talking about modified racing, double the price on the motors. Brushless cost stays the same as it was with stock.

Of course, none of this even remotely addresses the convenience, time savings, and extended run-times that brushless offers.

Sorry about the soapbox... couldn't resist .

I've got my bj4 geared at 75 tooth spur, with a 16 tooth pinion, works perfect for the track i'm on,

one note too, the Mamba max set up is quite a bit cheaper than the Novak and LRP systems, its not ROAR legal thgoouh, but if your track doens't follow strict ROAR rules, the Mamba is an awsome set up, for a really good price, I had a sphere comp as well, and I prefer the Mamba max because its alot easier to program with the USB adapter, and for the price, performance wise I can't tell the difference between the two,

What brushless motor (I see some are 7.5T, 5.5T etc) would you suggest for a 1/10th scale offroad buggy?

Also what about batteries, does it require anything special? ( I currently have older stuff 3300's at the moment)

4wd or 2wd buggy? 6.5 and 7.5 will probly be plenty for 2wd. a 5.5 wil lreally move a 4wd though. its too muc hfor a 2wd in my opinion. i run my BL on a new orion 3000nimh. it will work fine.

well like i said before, a 6.5 or 7.5 will be plenty. or the mamba 5700. they are all pretty close. it will be a ton of power though.

6.5 is prob about as extreme as you want to go with 2wd offroad. Even then... it becomes a real handful. I really struggled with 6.5 in XXXT as was constantly thinking "easy on the power, easy on the power".

If your radio has exponential settings then go the 6.5 and dial out some of the initial throttle. If you dont have exp settings, i might even consider a 7.5

I'm just running 3300's with my brushless set up, with brushles you dont really need the best batteries, since the motors put out more power already,

for 2wd I would get one of the smallest motors you can find, I ran a NEo 1 star in my BK2 outdoor, and it was as much as I ever needed, and I'm putting the Mamba Max 4600 in my MF2 now, I think anything more will just be a waste, and you can generally gear a bruhsless up alot more than a bruhsed motor, and still be ok for temps,

i know someone who put a mamba 5700 in a AE T4. had it geared like 20 to 78 or something. it kept the wheels on the ground ok. it was insanely fast though.

Just as a reference, I ran a 4600 in a B4 geared 24/81 and still yanked the front wheels off the ground easily when the track was sticky.

So yeah, you can gear it tall.

If I go electric again, I will be doing brushless. Can someone explain what the differences are between novaks 5.5 6.5 7.5 compared to how mamba is rating there motors?

Also, from what I heard mamba motors have the wires inside the can, is it easy to get in and change the length and how do the wires attache to the ESC.

I am actually looking hard at the Tekin units, but the mamba for the price has me interested.

If you're considering racing, definitely go with either the LRP Sphere Competition 2007 or the Novak system. The Mamba and others are not sensored so the throttle is very erratic. With the LRP system the throttle feel is very linear and similar to brushed. We spent a long time working on the throttle characteristics to mimic the feel of brushed

* For 2wd I would recommend a 7.5 LRP Vector X11 with the Sphere Comp 07' on settings 2/1/2/2. This should feel similar to a 13x2.

* For Truck I would recommend a 6.5 LRP Vector X11 with the Sphere Comp '07 on settings 2/1/2/2. This should feel similar to an 11x2.

* For 4wd I would recommend a 6.5 LRP Vector X11 with the Sphere Comp '07 on settings 2/3/2/2. This should feel similar to a 10x1.

I have had a Mamba system run awesome but I've also had some minor issues with them too.

I also have an LRP Comp/2 Star combo and a bunch of my friends have LRPs also, including the new 07 version.

First I have to say that the Mambas have more power... great for 4wd. A few of us have run Mamba systems and many guys have said they look like the fastest cars/trucks on the track.

And the throttle and brakes feel smooth on the Mamba too... I've even had a sponsored AE guy run them and say it was good. Anyone saying the Mambas are horrible either has never owned one or has an agenda. They aren't bad at all... very smooth in fact. Just a different feel than Novak and LRP.

Having said that I have some concerns about the Mambas right now, due to some weird issues I have seen before. But nobody else seems to have had the same problems so it may be a rare deal.

The new LRP 6.5 motor feels very good... it's stronger than my 2 Star I think.
