I personally think lipo safety isn't a big issue. As long as you are careful when charging them you probably won't have a problem. The Apogee packs have a slightly different chemistry then lipo and are supposed to be safer. I have used both that and a regular lipo and I have never had any issues. My apogee pack as ejected during 40mph flipping and it was just fine. If you are concerned about safety, the apogee 1500mah would probably be the best pack for you. A 3s lipo will be more expensive then a 2s lipo, so keep that in mind. A general guideline for 18th scale lipos is about $16/cell.

I don't have a lipo bag. If you keep an eye on the battery when you are charging it then you will be fine. The pack will puff up very large before it catches on fire. You can find a video on youtube and it should give you a good indication of how long it will take and what to look for in a lipo if it is about to explode.

A 2s system is cheaper. I could rant on forever but basically a 3s system and lower kv will be more efficient then a 2s system with a high kv. I say a good system has a big motor like a 370 size for lots of torque. If you combine that will either high kv and 2s or low kv and 3s it will be fast. In general, most motors will be safe up to about 50,000 rpm and most will last to 60,000+. You just multiply the kv by the voltage to get that.

I have a 2s setup. It is a Neu 1107 8500kv motor with a 1/10th cc sidewinder esc and 2s 1600mah flightpower battery. The motor draws a whole lot of amps so I need the 1/10th esc and high quality battery like the flightpower/apogee.

wat kind of speed difference is there between 3s and 2s? how fast would a 7 cell go compared to 2s? im allowed to post links just not ebay right ? http://www.r2hobbies.com/proddetail.php?prod=rcve00045 this is the one i am thinking of getting with something like this http://www.stevensaero.com/Apogee-Ma...N-p-17111.html

The speed difference would all depend on the motor. A high quality motor like a Neu (best you can get) would own on every voltage. A properly setup 2s system will have pretty much the same performance. The 3s would be a little more efficient.

What it all comes down to is that a brushless system in an 18t will be VERY fast. You will be most likely happy with any sytem. What I would do is get a 370 size motor that is about 5000-5500kv with a nice esc and run it on 2s. With that kind of kv you can step up to 3s if you ever feel the need.

Most people are more then happy with a mamba on 3s or even 2s. You can go whatever route you choose and you really can't go wrong. Just make sure not to overgear it and dont abuse the lipos.

A 7 cell will be faster then a 2s lipo at the start, but for the second half of the run the lipo will have it beat. A NIMH will fade during the run as a lipo is strong throughout.

how often do retailers exagerate the aspeed and by how much if they say it will go 43.5mph wat speed do you think it would achieve. what would happen if i brought a better motor to go with the esc in the car linked in previous message would it work or do i need a better esc? i may not be able to go with flightpower or apogee batteries as they are quite pricy do you know a budget brand that good lipo? if not the apogee may be good. do the apogee need a different charger because there chemistry is different?

quite often actually - those figures are always dependant on optimum conditions, but at the same time they're in the ballpark
and it's why so many cars come stock on the verge of being overgeared, which puts extra strain on the motor and esc.

it's always a worthwhile upgrade to go to a better motor and esc, the kit stuff is generally pretty cheap and not intended to survive much more than how the car/truck comes out of the box.

if you decide to go to a lipo pack you will need to have a lipo-specific charger

so brands are more pricey than others, but it's always been my theory that you get what you pay for (especially with RC stuff) - we're only talking a few dollars difference in most cases, and while saving a buck might feel good in the shortterm they seldom reward one over the longterm

The apogee uses a lipo charger. With the chemistry you can charge it twice as fast though. A lipo is limited to 1c and an apogee is 2c. I charged my apogee at 1.8c.

Heres an oldie but a goodie- Tamiya Tamtech Gear series. Cheap on Ebay about $70 RTR. Biggest issue is parts since they are no being discontinued. But at the price of new and used $45 RTR you can afford to buy a couple and they are extremely durable. I'm running a Tekin 5700Kv and 1/10th on-road wheels and tires and no probs. Bigeest issue with that much power is traction. That is my only complaint. With the tires it has as much clearance as my CEN ME16MT. Over 1" maybe an 1" 1/4. Plus it has a good buggy look and a body that helps seal the chassis from debri. I'm switching up to Tamiya 1/10 rally car tires to see it if it helps with the traction issues. Stock tires work well but they are small and wear very quicly.

This is where I got mine. You might be able to get them at other places now, but at the time I got mine this was the only place. Most other places had the cells, but in a 3s pack. This is the only place where you could get a 2s pack.

One thing I would like to suggest is outlining the parts you need to get the kit version running, along with rough prices of the parts. Maybe some reputable sites to buy from as well.

This is EXACTLY where I want to be. 1/18 scale talk. Mistery buggy I got from my dad from Thailand. Cannot find mfr or support for (broken)parts.Made by Huan Qi and the mane on th bottom of the chassis is Huan Qi. Says "tecnics super mini buggy" on the spoiler. Tha thing is very cool and lots of potential but I twisted the crap out of the plastic driveshafts. Part# HQ-707 and I've been world wide to find a distribotor for parts for 10 hours,total. Maybe some other 18th scale "swing shafts "would work.It has 6X10mm bearings and 12mm hex drive wheel hubs. I'd love to hang 10th scale wheel/tires on this. The length of the driveshaft is unknown 'cause the thing is twisted so badly. I'll have pix in a week or so when my card reader gets here. Maybe Kyosho has something I can modify. I'm an Associated 10th scale electric guy for the past 11 years and I love my T-4 but this little thing is WAITING for some hop-ups!

I would have to say the rage is better then the rc18t. Not only is it cheaper, but it doesn't need new drivetrain parts or any upgrades out of the box. It is a very durable car. I think the drivetrain holds up to bl power out of the box iirc.

I don't know why anyone would get the associated over the xtm. The xtm is well thought over and the manufacturer fixed all the bugs before they released it.

You might be able to find a body like that on ebay for a vendetta and just get bigger tires. OR you could make a german friend.

I have a vendetta st and have had it for awhile.. no issues.. until I destroyed the cvd's yesterday.. figured while I was in the process of upgrading it.. might aswell take a look at the motor/battery.. what size brushless would be suggested? I have probably 40 different lipo's kicking around.. as well as a bunch of 370-480 brushless inrunner style motors kicking around... (keep in mind these were all from aircraft I have had over the years.. don't know if they are transferable.) I am not to in check when it comes to cars... just wanting to hear what has been successfully been accomplished.

Cheers, Deaol

What about the Radline/Unimax 1/24th scale off-road "Master Series" hobby-grade vehicles? Looks like they've been out since Oct. of '07, but haven't really taken off yet.

It's my opinion that the only way they're going to stay in the market is by getting aftermarket parts made for them, and the only way that's gonna happen is if they get mentioned in threads like this one and board admins give them a forum of their own like over on R7R (mentioned below). Just my 2 cents.

BTW - I don't work for them or anything; I just bought 3 on eBay and would like to seem them succeed so they'll have a future in my collection for years to come.

For example: The mini-t is an awesome car. I love everything about it; although mine is extremely upgraded. I'm sure anyone who is happy with the mini-t has upgraded electronics, and weak parts. The stock mini-t isn't very impressive. My dad sold his because it frustrated him so much. I almost did; my mini-t had a lot of shelf time. Since mini choices were limited at the time, but I liked minis, I decided to keep it. After upgrading it, it's my favorite car. I have two of them; three at one point.
...
You don't even want to get me started on the mini-slider or mini-late model. I think you should remove the part where it says "great for racing" and replace it with "It's a novelty look-alike car." It can be made into a racer with lots of aftermarket support, but Losi made no attempt to make it race ready out of the box. What they did is slap a longer chassis on and added some more cheaply made parts, so they could make some money.
Me and a few friends have been running the mini sliders on my backyard track and they seem to work pretty good. There are certainly a few issues with them but overall they work pretty well. (See Foodstick post with video of night race).

The quote above makes me wonder if I were to build or buy another car in the same scale and wanted another sprint chassis and sprint car look what would people recomend other than the Losi?

Our initial decision to go with the Losi mini slider was the good detail and ready to run with fairly good performance. We are running on a 75' track so WOT runs down the straight away does not take anything more than a stock setup to get out of shape.

The price point was also a big factor, although I have since upgraded to a brushless micropro system.

Good thread, glad to find more info on the subject!

Just make sure to get a charger that will suit your needs now and down the road. If you are going to want to charge nimh packs and lipo packs, get a charger that can do both. If you are going to want to charge big packs, get a big beefy charger. The best charger is probably the TP1010c and then the TP610c. Get one of those and you'll be set for life. I personally have a cheaper FMA unit that works great for lipos, but doesn't have a nimh function. I got it because it was $40 and it does 6s lipo up to 10a.
