Rc10T4 Brushless Setup...

[Associated-08]

Hey guys, I just bought a Rc10T4 Kit and Before I buy the electronics I want your opinion.

Brushless Esc & Motor: Castle Creations 1/10 Sidewinder ESC w/5700 Motor

Lipo Charger: Hyperion EOS0606i AC/DC Balance Charger

Lipo Pack: Trakpower 7.4V 4900mAh Gold LiPo Car Pack Battery

Receiver: SR3000 Spectrum Rx receiver

Steering Servo: Z590 servo

This is what I have picked out for my T4. I know people say the Novak BL Setups are the best but I cant afford another $140. Any Suggestions of what to change up? I was thinking of going with the 4600 motor? What is the 5700 Motor classified as? 6.5? 5.5? Im new to Brushless so I dont know to much.

Thanks Rc Community, Mike

The Sidewinder system should be really solid. Novaks are nice (I have one) and their smoothness is especially good for racing, but the latest Castle firmware makes the Sidewinder quite smooth as well (from what I've heard). The 5700 motor will be roughly equivalent to a Novak 6.5, but really it's hard to compare brushless motors sometimes. The 4600 will probably be something like a Novak 8.5, which still has plenty of spunk in something like a stadium truck. If you're racing you'll want to think carefully about how much power you need (too much will be harder to control, not necessarily faster in terms of lap times).

One random thing. You need a proprietary balancer to balance that Trakpower LiPo. Unless there is some fancy adapter I am not aware of (which is possible), that Hyperion charger is not equipped to balance the Trakpower pack. Here is the "official" balancer for that pack (not sure if anything else would work without some soldering):

I run a Mamba Max 5700 in a XXX-T, which is pretty similar to your T4. If I was buying another system, I would opt for the 4600 for a couple reasons. For racing on 6 cells or 2S LiPo the 5700 is incredibly fast, but it really has more power than I can use on over 90% of the track here at Hot Rod Hobbies. You can look up the track, it is all over the web and in Magazines, the ROAR nats will be held here this year. It is not a tiny track, but it is fairly technical and the 5700 takes a very careful trigger finger to run it. I am almost to the point where I can drive it without a problem, but when I am battaling for a position, I still over step the power and end up pulling a wheelie when it would be nice to be able to steer. The 4600 is not really a lower POWER motor. It turns a lower rpm but makes more torque. Once you gear it for the same ground speed, the performance is virtually identical. The taller gearing will soften the edge a little, and give you finer gearing choices as I am very close to slowest gearing with the 5700 on this technical track. For all out bashing, there is no comparison at all. The 4600 can take a 3S LiPo and run circles around the 5700 on just a 2S. My Mamba Max will technically take 3S on the 5700 (The SideWinder will not) but the resulting motor rpm is so high, that I could not gear it for reasonable use. The 4600 ends up in a very good rpm range for high speed bashing.

In a buggy or touring car, the 5700 would be better for 2S use, but in a truck with the bigger tires, the 4600 is just a more flexible option. Both motor make serious power, topping 500 watts on just 2S, which is actually closer to the 4.5R Novak system, but they do it at a lower rpm with greater torque. If you just go by rpm, the 5700 is like a 7.5 and the 4600 is like an 8.5 but my truck out pulls 6.5Rs down the straight as long as I keep the front wheels on the ground. Keep in mind I also added over 8 ounces to my truck just to make it easier to drive with the power of the 5700 in it.

I have not driven the SideWinder myself yet, but it should have virtually the same response as the Mamba Max. It will be a little easier to drive due to a little more series resistance, and if you push it really hard, it will hit a thermal limit sooner, but it does not current limit until it get's too hot. If you want to gear it fast, be sure to check the ESC temps anytime you go up in gearing, just to be safe. The SideWinder is a "Sport" system so it won't take the abuse the Mamba Max can live through. The MM is just a total brick that has been pushing 14 pound truggies faster than nitro motors, so the 66% rating of the SideWinder is still huge power.

1) Good choice , maybe you should look into 4000 kv range motor(CM36 or Tekin Redline)

2) Good charger for a begin, 6 amps is perfect because it the recommended rate for "big" Nimh battery, The only main drawback is the very limited discharge ability. Not a problem if you plan to run on lipo from the start ( lipo does not need to be cycled).

3) Crème de la crème ?, better buy 2 or 3 of them, sure it's expensive, but that will allow you to run a whole day :P. Well handled high quality Lipo will last longer and keep better performance than nimh over time

4) Don't know about spectrum stuff, That should not make you unaware that it's best to keep a good distance between receiver and ESC/Motor.

5) Default servo will do the job, you may want to go for a faster servo later. If you do so on budget brand like Bluebird and Scanner RC are great. On big Brand looks into Sanwa and Futaba stuff.

Ok thanks alot. And thanks for pointing that out ss pede, I almost bought that.

So the 4600 would be like a 8.5 setup? and the 5700 would be close to a 6.5setup?

Thanks, Mike

What I said is that the RPM of the motors is close to that. But the Castle CM36 motors make more torque so they will push a much taller gear before they get too hot. RPM alone is not power. Power = RPM x TORQUE. The Novak (and any similar designed motor) by nature is going to have less torque capacity due to the higher internal resistance for a given number of turns because there is a steel stator taking up much of the room. The Inside of the coreless CM36 motors is all copper wire stuffed in there. This makes the motors handle more watts before they heat up. There is one down side to it though. The torque is very immediate and intense so it is very easy to break traction or pull a wheelie even when you don't want to. The Novak style motors come on softer so they are a little easier to control for a given power setup. The The CM36 7700 is still only a tick more RPM than a 5.5R, but it is well over 500 watts. The 4.5R is 520 watts, but a KV of 9,000 so it turns much more rpm, but less torque. I really don't think you could make use of that kind of RPM in a truck to really use it's 520 watts, where as the MM7700 motor is turning a fairly reasonable rpm and cranking out much more torque.

To sum it up, the 4600 will run a bigger pinion gear than an 8.5R could push and result in performance similar to a 6.5R when geared right. The 5700 will run a pinion gear bigger than the 6.5R can push and perform like a 5.5R. You can't directly compare the motors with the same gearing due to the large rpm difference.
