Mikeís Hobby Shop is pretty much the only good option for electric off-road racing in DFW. The hobby shop stocks parts for the AE B4, Losi and Kyosho RB5. All three perform well on the track. I donít see a wrong decision no matter which you choose. I used to see more AE B4s at the track but it seems to be more Losi at the moment. Kyosho has a good presence. Apparently the shocks and bearings in the front wheels are a little bit of a pain on the AE B4 but itís the current World Champion car so it is hard to argue with that. You can find parts for B4 and Losi everywhere but Mike seems committed to also stocking parts for the Kyosho. I race a Losi buggy and Iím happy with it. I would really like to try the Kyosho RB5 or Academy GV2 but I have so many Losi spare parts Iím staying with Losi. If you want to get parts from any hobby shop get the AE B4. If you donít mind less places to get parts Iíd recommend the Kyosho RB5. But really there isnít a bad choice of the ones you are looking at.

Servo- http://www3.towerhobbies.com/cgi-bin...&I=LXDWF8&P=ML
My track is medium hard clay, Tires- rears- http://www3.towerhobbies.com/cgi-bin...?&I=LXFHL9&P=0 fronts- http://www3.towerhobbies.com/cgi-bin...6-02&search=Go

There`s only one version of the kit that i`m aware of, so what aftermarket parts are a good idea?
The hex drivers are good. Integy isn't known for their quality craftsmanship, but the hex drivers are some of the best.

The servo is WAY too slow. Get something that is at least .10 sec. HS-5965MG, JR Z9100S, JR Z9000S.

Holeshots are usually a good all around tire for hard pack. I'd get M3 & R3. Panther Switch clay, taper pins, X3000's, it all depends on the track.

go with a fast servo, buy once. This is like your arms steering in car.... you want slow fat arms or your want lightning quick arms to steer. With a slow servo there is a lag on your imputs and can be frustrating.

I would go with an analog servo. They will last longer then a digital servo will. A digital servo simply checks the servos location more often then an analog servo does.

Get a digital. Don't skimp on the servo, do it right the first time. That is a good servo though

A non digital servo is not skimping, it is making the investment that will last the longer while delivering great performance.

So a servo with 102.76 oz. of tourqe and at .10 seconds is good right even if its analog.

You get what you pay for & a $70 servo isn't a cheap servo.

For servos as a new guy or inexperienced guy on a 2wd buggy, I would stay at least as good or better than these specs:

.90oz of torque
.15 transit time

you don't want something that feels overly twitching, but not so dead slow you have to anticipate the turn ALOT to make it. As a newbie, you probably won't really notice the difference between a digital and analog servo.

Something also to consider with your mamba max ESC. it only outputs 5V BEC. So, you will need a better servo to get better performance than the 6V spec you may see listed.

The 965MG you posted has good specs at 4.8V, so it should work well in a buggy. I use the HS-5925MG digital and love it on the mamba max in my T4.

As for Radios, I would at a minimum go with a 2.4 Ghz style system. I am VERY impressed with my new REACT system. works amazingly well and I feel like I am part of the car. The Spektrum one I had before worked well too, and I would recommend it for a newbie as it doesnt' have tons of settings like the React. Finding a used DX3 or DX3.0 should be fairly easy if you are money conscious, and I think right now they have a buy a radio, get a free receiver deal going on again.

As for tires, whatever the fast guys at your track use, go with that. If its a proline tire, you may want to go with a different brand of foam as based on experiences of others and myself, the foams breakdown easier than others.

have you decided already on battery and charger?

jr9000s is a sick awesome servo..... very reliable too.

that 5v bec on the mamba sucks though cause you will never get full potential of the servo.

I am going to say that even in a 2wd buggy, .15 seconds/90 oz torque (at 6.0v) is NOT sufficient. I would shoot for at least 0.10 seconds/120 oz. It makes a difference.

If you are just bashing then it really doesn' matter. For any kind of racing on the track however you will get faster laps with a quick servo.

Also, digital is worth it. HOlds the line alot better than analog. Servos are the LAST thing you want to cheap out on. This is an expensive hobby to do right if you are serious about racing.

9000s
9100s
Futaba 9452 is good too.
