Default Electric Buggy Choices?

I have a Losi XXX-T right now, and want to get a 4wd buggy to race. Right now I am leaning towards the XXX4 Losi buggy, but I really like the JConcepts BJ4, although it is probably too expensive. Can anyone name some other quality 4wd buggy's that I could consider. I want something a fair bit different from the XXX-T stadium truck (differenct motor position, etc.) Belt or shaft driven. thanks

I looked the Academy up on google, got some brief pictures. Looks like an awesome truck, believe it or not it is pretty much exacticly what I want. Is that Chassis carbon? Funny thing is a couple minutes after I posted this, I was thinking of a buggy with the same motor mount position as my associated 18t, and that one is setup just like it. Where can I get it? Also, it seems it may be hard to find parts for it, like at my local shop.

No the chassis is FRP, fiberglass reenforced plastic, but very sturdy. You can order parts and the kit from ultimatehobbies.com. Another thing that is kewl about that buggy is that you can mount the motor either side of the chassis and can mount the batteries in any configuration that you want. As far as breaking things and having to replace parts, you'll be surprised by how tough the car is. The car's arms and hubs are amazingly stout, almost 1/8th scale stout. Here is a website that will give you some more information: http://modelrectifier.com/search/pro...ew.asp?ID=6451

I am noticing a number of DNF's at our track in 4wd buggy. The front wheels are apparently kicking up dirt into the drive mechanism and the buggies are jambing up. Especially the Losi. Seems they can't handle dirt.

Most people have read this already, but the question keeps coming up, with different people asking. Here's my post on 4wd cars from about 4 months ago....

"If you're looking to get into 4wd, do you have options.... Of course, that's what makes this class so interesting right now (besides the fact that they are just plain awesome to drive). I'll admit I'm biased (see sig.), but here's a hopefully objective run-through of the current 4wd offers:

Team Losi XX4: This car was revolutionary when it came out in 1996/1997. It (swept?) won the 1996 ROAR mod nat's while still in prototype form and went on to win numerous US and European championships and 2 IFMAR world championships. The latest big victory I believe was the Eruo's in 2005. It is well known for its amazing suspension, as it breezes through rough stuff and takes to jumps like it has wings. It features a 3 belt drivetrain (sealed) with a dual slipper clutch and front adjustable one-way clicker unit. Losi recently re-released (the car had been out of production for several years) the Worlds Edition of the XX4, so parts and cars are pretty plentiful. The front arms can be fragile. You can find used xx4's at many hobby stores and usually one or two on ebay.

Team Losi XXX4: Why'd Losi discontinue the XX4 originaly? They made what they thought was a better car, and in many respects is. The XXX4 also has numerous national championships and a IFMAR title to its credit. The XXX4 is has a single-belt driveline (sealed) and is one of the fastest cars in a strait line. The smooth track handling of this car is very good, but if the track starts to break up or on harsh landings the car can bounce around and be a handful. It had several durability issues when it was first released, but updated parts (new front arms, shocktowers, and chassis) have pretty much made it one of the most durable 4wheelers out there. The drivetrain is good enough that several Losi team drivers have been known to cut every other tooth out of the belt to help eliminate friction.

X Factory X - 5: A small compnay based in Ohio, they saw the XX4 and XXX4 and wanted to have a combination of the best parts of both cars... so they made it. Known as the X - 5 ("double" x plus "triple" x = five) this car combines the single belt drivetrain of the XXX4 with the suspension package and weight distribution of the XX4. The car is offered as a converstion kit for either the XX4 or the XXX4, or you can buy an entire car. The car won the 2005 Roar Mod nats and has several top 5 finishes at major off-road races around the country in the last year - with only one "top" driver, Greg Hodapp, on the team. It is starting to pick up results in Europe as well. This car, like the XX4, has great rough track handling and super acceleration. Parts aren't a problem as most of the parts you commonly break (arms, shocktowers, etc) are Losi. I personally drive an X - 5 and absolutely love the car.

Kyosho ZX-5: A newer car on the market, this is the first shaft drive car on my list here. I haven't driven one, so most of what I know comes from looking at them and talking to others who have driven them. The car has a moulded chassis with a single aluminum shaft down the center; the motor and electronics are along the right of the car with the batteries on the left side. There are some weak points out of the box, but a few aluminum braces and the car becomes pretty tough. The car comes from the box with several front drive options as well as all the usual chassis/set-up adjustments and is available for a bit less $$ than the other top-level 4wheelers, so it has a great value. The car has yet to pick up any major wins (Has it won in Japan? I don't think so, but someone can correct me there); but it shows lots of promise.

Yokomo MR-4BCX: This car is going to hit shelves at the end of the Month, and the prototypes have shown a lot of good things. It features a carbon fibre dual deck chassis with a twin belt drivetrain (exposed). The car has a weight distribution similar to the XX4 and seems to share the excellent rough track handling. The Yokomo team had good results at the recent IFMAR worlds and has picked up several large wins in both Japan and Europe. We will have to see how the car does (and how well it is supported) after it is released.

JConcepts BJ4 (and worlds edition): JConcepts is another small company who saw something and decided to make it: they created the BJ4 very loosely off the Associated TC3 shaft design (the car is almost entirely ground-up new; don't consider it a "touring car conversion). Released in 2004, the BJ4 features a dual deck carbon fibre chassis with an alunimum shaft drive down the center, motor and electronics on the right, and battery on the left. The very first prototypes (about a week in existance) were driven to the 'B' main at the 2003 IFMAR Worlds, and the car has had great success since then. It was known to have very weak front arms, something which has since been revised. In 2005 JConcepts released the Worlds Editon BJ4, which may as well have been a whole new car. Still a carbon fibre chassis, the WE has the spur gear central on the car with shafts running front and rear. The batteries became saddle packs sitting in the back (similar to the XX4 and yokomo), and the motor got moved toward the front. This car won the 2005 IFMAR World Championships, so you know its a very capable performer. With the new front arms and bulkhead, this is an excellent car - if you can get your hands on one.

Predator X 10: Based in England, the Predator car has been around for along time. The best word to describe this car is unique: it has a completely differnt look and style about it than anything else out there. This car has a molded chassis, is shaft driven with the motor in the back left, front saddle packs, inboard shocks, a front wing, wind-tunnel tested body... it is stacked. The predator car has been around a while, in and out and in differnt versions, for a long time. An early car was raced very successfully in the early 90's by none other than Brian Kinwald. The latest version seems to be making a bit of a comeback - it seems much more prevailant and supported than previous versions. While it is a very potent performer, it is known to have weak spots (steering, arms), and you pay for the uniqueness in $$ and by having to order almost everything - even the wheels - from the comany itself.

Academy SB Sport: This car takes a whole different approach than most of the others to 4wd racing: while everything else is pricey, all-out performance kits, the SB Sport is a much, much cheaper car that with some upgrades can be competitive. The car is a shaft driven with a double deck chassis. This car hasn't won any big races, but it doesn't have a "factory team" per se racing and developing it. With some upgrades, this car is incredibly durable, and is probably the best choice for someone just getting into RC who wants a 4wheeler.

Durango: The Durango is a very unique shaft driven car made in Germany... that no one can buy. Just about everything on the car is hand made buy a man in Germany and campaigned by a select few drivers. Most notably it has several big wins in Europe and won the IFMAR World's Warm Up last year. This is a very unique car, but as you can't buy them, there's not much to talk about.

Schumacher: Schumacher used to make very competitive electric 4wd cars, but has not come out with anything in several years. They put together a prototype Cat 4k for a show in Europe last year. The car had a lot of people very interesting, but so far there has been no real word or action on producing the car. There are people who comeptitively race the Cat 3000, but the car has not won anything big (to my knowldege) in recent years.

That about sums it up - I'm sure there are a few cars I left off the list, but those are the major 4wd cars I could think of. I hope its helpful. As for me, my very first RC car was a XX4 - I didn't race novice first but rather 4wd mod. I loved that car, and in fact it is still built and sitting on my shelf at home. I bought and built a XXX4 when they came out and stuck with that car through almost all of its "growing pains". I found I could run very fast with the XXX4, but it was hard work. Whereas the XX4 was fun to drive, easy to toss into corners and throttle-steer out, I had to be right on the line, drive absolutely perfect with the XXX4. With the X - 5 I really feel I've found the best of both worlds - its easy to drive and will accelerate with any XXX4 you want."

Maybe there are too many small rocks in our soil. The guys are always asking corner marshalls to push their cars backwards to unjam them during the race. I'd like to know exactly where the problem is. Makes me reluctant to join that class of buggys.

Well, my first 4WD was a Losi XXX-4 G+. It was a great car, It accelerated very well and turning was incredible. On very smooth tracks, the car really shines, but on anything with a lot of ruts, bumps, rocks, and pebbles, the XXX-4 isnt the best.

Next, I had a XX-4 WE, it was a VERY fast car in the corners, jumps, and rough sections, but the accel always left me wanting compared to the XXX-4. My only gripe about it though is that the front bulkheads seem unnecessarily weak. I broke 3 in one race day. This was probably the weakest car I owned.

My current and favorite 4WD is my JConcepts BJ4. The car handles like a dream, accelerates the best out of the pack, it handles well on relatively rough tracks and is smooth and trouble free as can be. I have driven this thing into the ground, and so far, I have snapped a rear Graphite arm. She just wont die.

So, my recommendation for a first time 4WD is going to be... The BJ4. If you can get your hands on one. But if you do, you will not be disappointed.

I would love the BJ4, ever since I read a review in RC Driver I have been in love with it, but at $475 for the worlds ed. I just can't do that. They are no cheaper on ebay either, and I only saw 2

If your having trouble with debree getting into the car then take some velcro tape, you can buy the stuff at wal-mart for dirt cheap. Line the side of the body and the side of the chasis with it. Mount up the chasis and you should be set. Also pick up a underchasis protectant piece. I think AE makes some that are pretty much universal that sale for like $10. This should keep everything out of the car and keep it in tip top shape. Odds are, if you talk with your lhs they can order up the parts for the car. Even if they can't, the academy v2 is around $100 less than the competition and an extra $50 in spares shouldn't be a problem. The only realy complaint I have heard about parts availability is that you have to use academy rims. Other then that, the car should be bullet proof and maintanance free. belt driven cars require a lot of work to keep clean and running strong.
