RE: whats wrong with the hpi e10?
 

Thats really nice .... I was expecting it to be much more expensive :D

BTW what kind of battery should i get? Im looking at a lipo but im not sure on how to choose :(

What will be best for a 6800kv motor? Will this be good enough for racing? If not...I don't mind using the 4000kv :D

RE: whats wrong with the hpi e10?
 

Batteries you'll have to research yourself. I don't rec batteries, as they are all different and some folk have preferences, but I will say to stay away from the real cheapies. To save yourself trouble, get hardcase LiPos, too. They are safer. This is where Itell you that the LiPo specific charger should be the best you can afford. In fact, the LiPos themselves should be the best you can afford. To give you an idea of how expensive it can get, go to Maxamps.com.
Those batteries are some of the highest quality there are, and you pay for it. The chargers, too, but they will serve the buyer very well for years.

Myself? I use Venom 2S 30C 5000Mah hardcase. They are, like Duratrax, at the limit of of inexpensive cost vs performance. Anything cheaper is junk. I've gotten good life out of them, and they are consistent performers. My charger is the Hyperion E0S606i, and does very well. It set me back $200

6800Kv may be too much. It is definitely too much for drift. Going closer to 4000Kv will serve you much better, and still have the power for grip driving.

RE: whats wrong with the hpi e10?
 

Cool :D

So the 4000kv would be for drifting :D

What's the best rating for a motor for competition racing?

Also what Spur gear should I use to get more acceleration?

RE: whats wrong with the hpi e10?
 

im selling a e 10,  gave to my son for his birthday 7-8-11    $130    used for 3 days. he wants an offroad rc.  will trade for an off road buggy or stadium truck.   includes everything rtr.

RE: whats wrong with the hpi e10?
 

4000Kv is a start. I wouldn't go higher than say, 4800Kv. Any higher, and the power delivery will be a bit too harsh for good drifting. The motor will serve well in grip driving as well.

Consider this: an on-road car can't turn at anything approaching 45 MPH. It will simply flip. A very high rated motor will have breathtaking speed, but try to turn. See where I'm going?? That breathtaking speed will be hard to modulate in drifting, and if you don't get good response from the power system, you won't drift well.

So don't get too enamored of high-Kv motors. That's the Traxxas mindset. "Go fast, corners be damned." :D

Drift is ALLabout corners. Your top speed drifting won't exceed 15 MPH most of the time. A 4800Kv motor will still get you to a speed where you can't turn, so it's more than enough.

RE: whats wrong with the hpi e10?
 

It's tru what you said man

Would that even be good if he wasn't a drifter lol

RE: whats wrong with the hpi e10?
 

BTW what spur gear should i use?

RE: whats wrong with the hpi e10?
 

Well, that's a 1/18th scale system, which is not exactly the same, but I think you're getting the idea.

On gearing, start with what you have. If you think you need to go lower (or higher, as the case may be) get pinions in one or two tooth increments. You can get spare spur gears in four tooth increments (such as 90, 94, and 98 tooth, as an example). Gearing is by personal preference, so go with what you are comfortable with.

Try not to find a "comfortable medium" with gearing between drift and grip, because they are so different, and it will be a waste of time and effort. Gear specifically for each discipline. The car will perform better that way.

RE: whats wrong with the hpi e10?
 

Thanks :D

What do you think about this battery?

Tenergy 11.1V 5000mAh 25C lipo

And will this motor cooler from integy be good enough??

RE: whats wrong with the hpi e10?
 

Whoa, dude!

At this pace, you might as well get a higher rated chassis! With all the parts you have listed, you can get a TA05, or at least a model with more option parts on it. TB03D? Or a mid-level TC chassis that will convert to drift (most TCchassis will).

At this point, what you are contemplating may be too much, even for the TT01. It sure sounds like it.

Try looking around, and I'll bet you will find a higher rated chassis for a great price. Iknow of one already - the Ofna JL10e TC chassis (the shaftie, not the drift). It's a roller, and costs $120. Electronics are needed, but the roller is so affordable, it will allow you to do as you are contemplating and be able to take the punishment (Ihad one, Ican attest to it's durability), and it does well in drift, even better for grip. It comes with grip tires, so the Raikous are still needed, but you will see just how well made the JL10e is, compared to the TT01. Ofna's #1 driver, Jeffery Lin has won races and titles with that chassis. Forget option parts with the JL10e - it doesn't need any! :)

It's the best alternative to the TT01 I can find, and it's price is a draw. Imay get another one, for RCGT.

So rethink what you are after. I'm trying to save you trouble and expense, and steer you to something that will grow with you, and not cost an arm or a leg.

On the parts you listed, the battery is a 3S. You will have to check the power system you plan to get and see if it is rated to take more than 12V input. For most apps, the 2S is plenty. The cooling fanis always a good idea, but some power combos come with fans, But Iwould get one, only if Ineeded it. If you gear correctly, you won't need the fan.

Givethe chassis change some thought, though. I think you won't be satisfied with the TT01 now.

RE: whats wrong with the hpi e10?
 

I think ill go with the TT-01R. Not expecting to cause any damages as i take good care of my stuff. I do intend to go for the JL10E in the future though. Looks like it would make a great on road racer.

BTW should i keep the original differentials or swap them out. How does one way differentials benefit the car? 

RE: whats wrong with the hpi e10?
 

The diffs should be strong enough. Unless, of course, you want to dabble with one-ways.

The one-way works like a spool under power, meaning both front wheels drive under power. UNlike a spool, the one-way lets the wheels freewheel off-power, so you won't have brakes or reverse at the front wheels. While this might sound detrimental, it really helps on-road cars drive through corners, when standard diff-equipped cars have to let off power, to enter a corner.
For drift, the one-way helps the chassis "swing out" easier, making initiating a drift easier. They also help the car keep it's "attitude"during a drift, and set up for transitions (left-right-left, for instance).
If ball diffs are available for the TT01, you could try those. They are easily adjustable, and don't need tobe removed from the chassislike gear diffs do, but they do require a bit more maintenance than gear diffs.

One-ways will not be helpful with bashing - you will most likely end up ramming into something, because the braking power of the car is significantly reduced.

The JL10e is a fantastic drifter, too! Ihad mine set up as one, and it performed very well in that role. I sold it because I'm primarily a belt-drive guy these days, but Iwill do another shaftie, if it's the JL10e (nothing wrong with the TT01, Ijust prefer the JL10E).

RE: whats wrong with the hpi e10?
 

Thanks

yup...The JL10E is really cool :D That's why i'll prefer to use it as an on road racer :D


BTW how does braking in Electric rc cars work. They don't have a brake disc around the drive shaft like nitros so im guessing the ESC slows down the motor or something

RE: whats wrong with the hpi e10?
 

The motor.

Brake strength is adjusted (if the ESC is adjustable) by the ESC, or at the transmitter, if you have an adjustable transmitter, but the motor does all the work.

RE: whats wrong with the hpi e10?
 

Nice :D

BTW are belt driven cars better than shaft driven?

RE: whats wrong with the hpi e10?
 

Yah, this is the age-old question.

It's a personal thing, whether you like belt or shaft. Each has it's place, but generally, shaft drive will be a bit stronger than belts, but belts are quieter and more efficient, once adjusted correctly. Most beginners go shaft, because the idea of adjusting belts is too complicated (it's not, really), and beginners as a rulewill run their stuff in some pretty bad conditions.Belts do not last under that kind of abuse.
Belts need a clean surface to run on, so rocks and debris don't damage the belt. It's why most racers use belt-drive.

It's a good idea to have a clean surface, even more so for drift, because the car is dependent not on the traction of the tires, so much as the attitude of the chassis. any pebble will upset this attitude if the car runs over it, so it's always good to run clean. That applies to belt or shaft. Running on clean surfaces will help your car last longer, too. I see and hear of guys running their cars in all kinds of conditions, and they wonder why their cars don't last long.

RE: whats wrong with the hpi e10?
 

Thanks for the explanation :D

WRT to the 4000kv

Will this be enough for drifting?

RE: whats wrong with the hpi e10?
 

The vid is choppy, but yes. That car is going fast enough.
It's hard to tell if the guy went full-bore at any time, because the area he's running is too short, but as far as acceleration, it seemed powerful enough. If that speed seems acceptable to you, Then go with it.

Towja, didn't I? :)

RE: whats wrong with the hpi e10?
 

yup lol :D

RE: whats wrong with the hpi e10?
 

One last thing......

If you go BL, get a tempgun. Tempgun.com has a few that are very good and don't cost much ($30). You will want to check your temps, to see if your gearing selection is correct. You want to run as cool as you can, for any given gearing selection you make.

170 degrees is bad. Anything approaching 200 and you are damaging your motor irreversibly. I keep my temps around 140, but my chassis are pretty drag-free (that's another benefit to belt drives), so it's easy.

RE: whats wrong with the hpi e10?
 

Thanks for the tip :D

I believe the Spektrum DSX3S comes with a temp monitor. BTW should i get a fail safe?

RE: whats wrong with the hpi e10?
 

The DX3S is for nitro. Spektrum has another TX out that is better than the DX3E, but not as expensive as their flagship, the DX3R and DX3R Pro. I forget the number.
It has an LED window on the right side behind the steering wheel.
No need for a fail-safe. After binding, if you use a Spektrum, it will automatically set itself to a default or neutral position if contact between TX and RX fail.

RE: whats wrong with the hpi e10?
 

Yup they are thr DX3R and the Pro. Pro is about 340US. Not sure about the DX3R though.

Also will front and rear stabilizers benefit the car?

RE: whats wrong with the hpi e10?
 

You could put them on, but I find it a waste of time. They are actually more beneficial for grip racing, but not much else. If you plan to do some grip driving, you could mount them, but not attach the armns to the springs when drifting.

RE: whats wrong with the hpi e10?
 

Nice :D I think ill go with them since im gonna be doing some racing with the kit also :D
