Status: offline 		I just bought a XX CR Kinwald edition buggy and I need info on it. Is it good or is something that I wouldn't want to race? I need info! What size battery packs would fit in it? Where can I get tires for it, is it worth racing? If you could please give me some info I would greatly appreciate it. Thanx!

Use a 6 cell 2400 matched pack for racing. you can buy tires and wheels at a local hobby shop. Use losi red ifmar pins for the tires there awsome.

Go to [url]www.integy.com[/url] for some good cheap matched packs. They have pre-built packs starting at $39.00 for some 3000 NiMh packs and non built packs starting at $35.00 for 2400 NiCads and around $39.00 for non-built packs.

You can also find pre built packs at Tower Hobbies that start around $41.00 (SMC batteries).

There are a few other places as well, but that should at least get you started.

I've got a XX Losi buggy that is quite fast. The difference between it and my B3 is minimal. It should do just fine for racing. I would even check your LHS for parts. Several shops around me still carry parts for the XX.

Status: offline 		Cool, Thanks. What type of motor are you running in your xx? How long does your battery last and what type of battery do you have in it? I'r going to be racing agains a guy with a savage. We're racing a mile track so i need something that will last me like 10 15 minutes. Where can I get tires for it too??

Status: offline 		I've got a Peak Racing Hellfire RS 24 which is a 27 turn stock class motor. It's pretty quick for a stock class motor but tops out around 22 - 23 mph. I get a good 12-15 minute of run time out of it with a non matched 2400 NiCad pack.

I've recently upgraded my B3 to a Trinity Speed Gem 2 Amythest, 17 turn double wind motor. This motor gets my B3 up to the upper 20's to low 30's and still gives me about 11 minutes of run time on the same battery pack. I haven't upgraded to matched NiMh's yet, but am planning on doing so within the next month or two.

With a 3300 NiMh pack you should get about 12 - 15 minutes with a 17 turn motor like the speed gem. If you are going to be racing a savage I would look at something like a 15 turn motor, assuming the savage is still running the stock engine. This would give you about the same top speed as the Savage, maybe a little more but would be much quicker than a Savage.

As for tires any buggy tire will work. Most rims will probably work as well, but you can just re-use the ones you have now. To take them off put them in a pot of boiling water for 20-30 minutes, pull them off and with a towl around them press in on the seam of the tire/wheel and they should come right apart. Clean up any glue left with a razor blade, flat head screw driver, etc. and you can now mount new tires on them.

Status: offline 		I can't go with anything lower than an 18 turn motor because my esc. Where can you get 2400 NiCad battery pack for low price. Maybe a used one or through a trade? Whats the difference between a pack and a matched pack? Is it just that the batteries are lined up differntly or what? How much time would I get from a 2400 NiCad pack with a 19 turn double modified motor? Like 15-17 minutes?

Status: offline 		You can get cheap 2400 NiCad packs from Tower Hobbies. I'm not sure of the current prices but I got my Peak Racing 2400 packs for $38.00 for two. They are sold as pairs for the T-Maxx but they work with any car. Orion also makes similar packs also.

The difference between matched and non matched packs are several.

The matched pack will generally have slightly higher voltage which will increase the speed of your car.

The matched pack will also carry it's voltage longer into the duration of the charge than a non matched pack. Since the non matched pack isn't matched the cells might have different voltage and duration from cell to cell. This means that some cells will discharge faster than others causing a loss of speed before the whole pack is discharged. With the matched packs since they have very similar numbers they carry their voltage then just die.

Overall run times will be similar.

With a 19 turn double you should get around 11-13 minutes of run time, depends a lot on driving conditions, track your ability to conserve battery, etc. A general way to guess your run times with different turn motors is to drop 1% - 3% run time for every turn you go down.

If you are really wanting to race a Savage I would look at a new ESC as well as a faster motor. I know Mtroniks makes a forward/brake ESC that goes down to 12 turns for around $35.00 - $40.00 and you could match it up with a 14-15 turn motor which would give you enough speed to hang with him with out much problem.

The other thing to consider when racing somebody with a monster truck is that they vastly outweigh an electric buggy. If you or he is not careful he could end up doing a lot of damage to your buggy if he lands on yours, runs you over, etc. Best to be either faster or slower than him.

Status: offline 		Are your peak batteries the white ones that you get from tower hobbies? Thanks for the info! I now understand what the difference between non matched and matched packs are. I am going to invest on a new esc when i get into true racing, right now, it's just for like going off the jumps at my park and in my backyard. But I am truly going to invest in one soon! Are there any certain wheels I would want to get? And do buggies need battery and reciever boxes or is that only nitro? I'm not sure. Are the batteries that you have the Power Maxx 2400 mAh packs? And do you know if those would work in a buggy...? They're selling for 37.99 dollars for 2 which is pretty cheap but in the picture I have it doesn't show if it has a plug on it or not... so i don't know. Thanks for the info and advice!

Status: offline 		Yea, my batteries are the Power Maxx batteries. They are not the greatest but for the money they are a good deal ($19.00 per pack for a 2400 mAh). The will work in any electric vehicle that requires 6 "Sub C" cells and they do come with Tamyia plugs.

You will need the receiver for the electric buggy, but won't need the receiver battery, at least not on an electric buggy that has an ESC. If you have a mechanical speed controller you would still need the receiver battery. Most ESC's power your servos off of the main battery pack so you can eliminate the receiver batteries.

Wheels, if you can find them stick to Losi buggy wheels, they are a bit different then associated, though I'm pretty sure associated would work with them. You should be able to find them at your LHS if they carry Losi parts or mail order them from Tower Hobbies when you get your batteries.

For the ESC it's just easier and cheaper to do it now before you buy a new motor. Picking up a 19 turn motor now then a 15 - 12 turn motor later will end up costing you twice as much in the end. Of course you will have two motors, but it's just more expensive that way.

Status: offline 		ok thanks for the information! I think that I will be able to beat the savage but it clocked out at 32 mph. But he just put a bunch of heaveir stuff into it so its down to around 30 mph or less. I found the power maxx battery packs at tower hobbies. A set of two of them is 37.99 dollars. 2400 mAh. Would I want to put deans plugs on my connectors? or not? I'm not sure because right now they have the regular tamyia plugs.

Status: offline 		WEll they do get less resistance and if you ever plan on racing I would. to do that you need a good soldering iron. Mines only 45 watts but works great. I bought it a radio shack for 20 bucks with a stand and everything. Didnt know how well it would do but it get the job done for me.
