one way to tone down the wheelie is a smaller wheel/tire and like road tires or something of the sort. my buddy has an mt and it does wheelies like crazy. mine with the mamba still doesnt. has anyone locked their diff?

Mr. Mugen

Here it is. If you had a 2000mah (2 amp) battery and it had a cell rating of 1C it would be able to dump 2 amps continuously. Now if the same pack had a 12C rating it could dump 12 times the capacity of that pack...so if it was a 2000mah pack it can now dump 12x2.0=24a....if it is a 2000mah 20C 2.0x20=40a....follow?

Hey, I recently purchased a RC18MT, and I grabbed these upgrades as a start... how did I do? I wanted some sleeves for the outdrives but thetoyz only had them in blue so I may just check around a plumbing shop for some brass ones that fit.

RC18 series Spur Pinion Gear COVER for the 18T 18R 18B 18MT (item #DP101 red) $12.99 x 1 $12.99
Rollover White antenna for 1/18th with mount (item #BRP2511 White ) $5.99 x 1 $5.99
RC18T 8.4v stack Elite 1500mAH NiMH battery pack (item #W EL1500-L32X1D) $27.99 x 1 $27.99
BRP RC18T 4mm & 8mm Axle Shim Set (item #625) $3.99 x 1 $3.99
RC18T 18 Series Steel diff and input gear (item #SAR035T14T) $13.99 x 2 $27.98
Team Associated Shim set (item #ASC21141) $0.99 x 1 $0.9

So basically, getting steel diffs, the gear cover, some shims, and a pretty cool 7 cell battery :0 The extra 1.2 volts should inch out a bit more speed for me Any other must haves?

Opinions?

@kukkudo If the batterie is for your transmitter, than ok, it is for your car, than you should choose a battery that can sustain more amps.

As for chargers, they seem reasonable but there are betters in hobbycity. Depends what you want them for.

kukkudo

What do you mean sustain more amps?

patatchim

Constant discharge: 3-5C

Since it is a 2.5A battery, you can draw 3*2.5A = 7.5A , or on burst 5*2.5 = 12.5A

your motor and speed controler will pull or draw more current than that. So your batterie will get damaged pretty quick.

You should choose a batterie which has a constant discharge bigger than 15C, where c is the capacity of the battery.

kukkudo

Still confusing for me I pm you.

if anyone wants to trade for a nib rc18 gear cover that i bought for pro pulse (doesnt fit) pm me! i want sealed bearings or aluminum wing mount or trade for stock truck body plus cash.

Thats the battery my bad the transmitter and this both look the same.

patatchim

Yep. that seems more appropriate for the rc18.

kukkudo

Should i go higher in MAH? Or that pretty good

A member not a company admin on the hobby city forum said:
don't know much about any RC car, so I am no help with the battery info. However with the charger you may prefer to use a charger that is capable of higher charge rate. The battery you indicated can be charged at 3 Cell (11.1 volts) and 2.2amps on a lipo charger, which will take an hour at that rate. All of the chargers you have picked out will take considerably longer.

True?

Derigor

I dont charge anything over 1C ever. I dont care what chemistry it is. Better safe than sorry. (I hate having to buy new batts).

Oldzy: About your reverse issue on the mongoose, did you look at the different settings for that sucker? I think you can program in delays and deadzones and what not for the reverse. You might try resetting the esc if you havnt already.

I have 13/57 gearing on my buggy, it hasnt done any flips... then again I dont have a lipo... yet.

patatchim

kukkudo , there are few lipo batteries that can be charged at more than 1c.
If that bat could be charged faster it would be announced on the webpage.


What the guy from hobby city said, is true. The battery has 3 batteries in series, each cell as nominal tension of 3.7V. So the final voltage is 11.1v.
Also your batterie is 2200mAh. Which means that it can deliver 2A for an hour(not quite true but, it doesn´t matter for now).
It also means that the charger is going to supply 2200mAh in order to charge the battery in one Hour. This means that the charger is going to charge at 1C. C represents the capacity of your batterie.
YOU SHOULD NOT CHARGE LIPO BATTERIES AT MORE THAN 1C.


If you feel uncomfortable with all of this terms, I suggest you should use nimh batteries which are safer (you should be careful when charging any kind off batteries) .
You can buy a charger that will allow you to charge lipo in the future.

So confusing all the chargers I have you charge it red light when done green light. Works fine too I dont get this stuff with all the numbers etc. I just need a charger that will do the trick.

http://www.hobbycity.com/hobbycity/s...Charge_Capable

That seems to have lots of good reviews.

patatchim

Yes, it will do the trick. It wont charge at 2.2A it will charge at 2, but yes it will charge your batterie.

But be careful with lipo bats.

2 packs at once! neat!

i would recommend a charger that lets you set the charge rate at 1c and not have to worry about doing the math to set the right amp rate. ie: set it and forget it! my FMA 4s will safely & properly charge any lipo pack i have without touching a single button! great for lipo newbs!

Steve441

I have the Hyperion Duo - Super Easy charger to use with Lipos (auto balance) with 10 battery memory, storeage feature, (great for me in the winter). Download upgrades via computer internet link - etc. etc. The best.

sonicj

My Feedback: (2)

i was reading lipo incident reports on another forum and it seemed the good majority of lipo fires were a result of the user incorrectly setting the charge parameters, forgetting to change the parameters, or the charger somehow loosing its charge settings. i can easily see how this happens as my mind is often in a million different places and in the moment sometimes isn't one of them!

Steve441

Indeed - You could endanger your family by charging your Lipo incorrectly - Keep this in mind - These batteries need special attention and they are great.

Steve441

My charger - Hyperion Duo (way expensive) checks each battery before it starts charging and won't charge if basic settings are not correct. That is a nice feature for saftey.

Snipin_Willy

What is the perfered gearing range for a 6800kv brushless and what brand of pinion are best in this truck?

kukkudo

I bought the 18R today

What kind of lipos are people putting in these? I find the stock size is very difficult to find batteries.

http://67.199.85.166/main/productdet...ory=5009.xxxxx

Is a direct fit and is pretty cheap only downside is that is 2S

Anyone know any other 2S's or any 3s's? (prefer)

The Reedys battery size is: (Same as stock)

L:95.25mm
W:25.4mm
H:12.7
