Its a shame people knock a product simply because they spent so much more and they cant stand to see a cheaper product that is actually better. The one and ONLY one place a Zippy Lipo comes short is with ROAR approval. I too use SMC, Reedy, and Trakpower Lipos. Sorry, they just cant keep up with the Zippys. Its really not even close. You name it, 17.5, 10.5, 5.5, 7700, on-road, off-road, bashing, racing, 18th, 10th, 8th scale, its really no comparison.

Sensored brushless motors are old technology. Sure, they will be on the forefront of the racing scene for a while. Thats what happens when money talks. Many great drivers are making the switch, they too can see the benifits.

Like I said, I have bought from HC. I can get Intellect locally at Very sharp prices.
The difference isn't worth buying O.S.

As for s/less. Have You tried it with HIGH turn motors ?? We are talking 21.5 here.
Not under 10 turns.

If you can get other brands at good prices then thats good. I personally don't think HC lipos are more powerful or longer lasting than most others on the market, just light years ahead in value. It about time the other manufacturers got a clue, and Im glad to hear it.

I have used my MM witha 17.5. Earlier firmware had lots of trouble, but more recent updates did much better, it was totally driveable. Now I use the pro so I am not sure about the newest updates. Maybe since so many racers use sensors they gave up on perfecting it.

Default Lipos

For me, it's all about support with the Lipos. I honestly don't want to get a lipo from Hobby City that is dead on arrival only to be "up the creek" getting it replaced (yes, they're cheap, but it's sad when the cost of shipping it back is more than the battery itself and you're still not guaranteed to get a good one).

I like that I can pay more and then great customer service if anything goes wrong. I know people who have had one of the name-brand batteries go bad and have them replaced for no charge (including shipping) by the name-brand company. And even with Zippy's, by the time you get a decent hard-cased one, the extra cost to get good customer service doesn't look that bad to me .

But obviously, your mileage may vary .

I understand your point for sure. There is definitely alot to be said for good customer service. The problem I have is when you have to use that customer service more than the guys without it.

If I buy a Mercedes Benz and they replace it free of charge everytime it has a problem, I would rather keep the Ford Escort that keeps running, even if I know they will not answer my calls if I do break down. If it ever does give me a problem, I have 2 more in the garage!

I know this is a bad analogy, but its all I got!

I know between myself and others at local tracks of at least 100 packs from HC, 1 problem. Meanwhile locally, 3 SMC packs have recently puffed up with no explanation and free replacements given, showing it was not user error, but an ongoing problem.

I guess its a similar situation to EZRun brushless systems. I own several Mamba systems of various sizes, and I think they are the best in the world. But I cannot argue that my EZRuns work just as well in almost every application, smoother in a few situations. As long as they continue to hold up I see no reason to spend the extra money to make sure I can return it.

Default Response from Castle

I got a response from Castle re: using a 21.5 with a Mamba Max:

Please let me know if you have any other questions. I'm happy to help.
Also, what about a 21.5 motor that is "designed" for both sensored and sensorless use like the DUO motors? According to the text at AMain, the DOU is designed for both sensored and sensorless use.

Thoughts?

I'd put money on it that the motor will still stutter off the line. The original Tekin R 1, had problems with this too. Sensored drives the high turn motors much better.

I have been running (only for a short while) a Tekin Redline 21.5 with the RS Pro and it absolutely kills the silver/sports tuned motors. It's so unfair it's not funny, so I went back to the black can until most of the field will go brushless too. One mention here. I have managed to catch up to another driver running a different brand BL speedy/motor when running at my best with a black can, but am not sure why. I think he had not nailed the setup properly. Or maybe the Tekin is that good. The again I got trashed by another driver with a black can when I was running my BL. This guy is a very experienced driver however.

There still a lot of experimentation to do, but my guess is that the equivalence silver can-21.5 is arbitrary to some extent (or perhaps there simply is no higher BL wind) and not based on the motor parameters (or only loosely).

I have to agree with this. I have bought the LRP SPX Stock Spec speed controller. I have never experienced so much power and RPM on brushless motors until now.

Using advanced timing on the motor and profile 8 on the speedy - unstopable!
