What's the price for ?

[himalaya]

I found this today, Nothing special but the price.

Anyone have an idea what they are charging for?

You have got to be kidding...that price & only 2s capable

You could buy 3 mmp for that price

I think someone forgot to pass after puffing!

Man that thing is incredible, it can handle 1 AND 2s!!!!!


Who uses 1s lipo? Save for the micro heli and plane guys. Is that going to be the new ROAR class. 1s lipo powered stuff? Maybe make the vehicle 30lbs, and power them on 1s? Then all of those "540 amp" capable escs will be really getting a workout...

But this does have a built in BEC, that must be a first...

Probably the first step-up BEC...

Quite true, but I think it will be a pass thru. That way the servo is reacting at the same speed as the rest of the car...

They are quite small and powerful little components. I mentioned this before in another post some where.

Edit: A good one would be to have a step up and a step down DC/DC regulators to do the job from 1-12S. Find a way to have the MCU or something else control it automatic if one goes from 1S to 2S or 12S if he's feeling happy.

They are charging for having figured out the optimal timing for running spec motors on 1S LiPo.

The big thing for Carpet racers is now spec motors (typically 13.5 and 17.5) on 1S Lipo. This speedo has timing profiles optimized for those spec motors running 1S Lipo for oval racing. There is a big to-do about this because the optimized profiles supposedly were good for .1 to .2 seconds a lap at the "Ovalmasters" race.

The interesting thing is that some industrious folks figured out how to mod a MMP (have to actually take some components off the board) to use it with 1S Lipo and then used the C.H.E.A.T. mode and were just about as fast.

Tekin is promising to shortly have the proper timing profiles for their RS series to match or exceed the AE speed control.

This speedo generated lots of complaints among the oval crowd because all of a sudden there was a speed advantage to be gained by spending lots of money. I think they are all hypocrites - they have no problem spending $400 on the latest and greatest chassis every year, but a speedo? No.

What is so cool is that the Castle MMP for $128 is competitive with this - really sticks it to all the guys that spent $400.

That one guy in rctech bought one. Lets see how fast this ESC will make him lol.

Wow, I had no idea people were that dumb. Running 1s lipo? Why not make a real sport out of it and see how many people can run a 1hr race with 200mah? That would make for a fun spectator sport, car made out of paper moving at snail speeds to conserve energy... At least you could use a cheap speedo...

They are not dumb. At least the 1S Lipo thing is not dumb. What it has done is allow the oval and road course racers to get the benfits of Lipo (and move away from NiMH technology) without either: a) having cars to fast to be controllable, or b) needing to run motors that are not readily available.

There isn't a lot of choice for pack voltages when using LiPos. Using the 2S lipos common in touring cars and 1/10th scale off-road cars makes carpet cars too fast for most people to drive even with the slowest motor available, the Novak 21.5. So by using 1S LiPos, they now have a selection of speeds that can accomodate entry level racers (17.5/1S) all the way to experienced drivers that want really fast cars (7.5/1S).

At my track the current record for 1S/13.5 pan cars is 90 laps in 5 minutes. or an average of 3.3 sec/lap. They are not slow by any means. They are averaging 23 MPH around an oval in a space 35ft by 60ft. Unless you have driven on carpet, you have no idea how fast these things can go when traction is essentially unlimited and you don't have to lift for the corners.

Do you have a car that can make a U-turn in the width of the typical driveway at 20+MPH? And do it 180 times in 5 minutes? 1S Lipo isn't dumb just because you do not have a car where 1S is useful.

Well, I could go into the fact you guys are racing with some of the worst designed motors on the planet... But I guess I can skip that part.

Anyways, 1s lipo is dumb when you could run 3s lipo, and a motor with 1/3 of the kv and do the same thing. Plus you could run a lighter battery with less capacity and have less anp draw and voltage drop. If the traction really is unlimited more power can be used.

I do not race, and have not raced on carpet, but I do know electric rc. I understand that you guys are stuck with roar (or whatever) rules and that you can only use certain motors. The fact you are working around this by using 1s lipos (and most likely not maxamps) that are very high quality does show that there are people with some creativity. The principle of what you are doing is a bit off, and the rules need to be changed to allow for that. Just making stuff work is not always the best way to go.

This is why I do not race. The rules can never keep up with the technology (as indicated by this 1s esc that has an advantage) so as usual the deepest pocket usually wins. I am glad to hear the smarter people are making do with a much cheaper esc (mmp) but that does not change the overall issue I have.

As long as you are having fun nothing I think really matters!!! It is just a hobby and should provide some relaxation! Please do not take my comments as anything other than my skewed beliefs, and I hope I have not insulted you in any way, as that was not my intention.

It might be just the hype going on when the CRC guys won some races using them. I've contacted AE, got a reply, but then nothing more. I hope that people buying this ESC wins many championships .

Like I said above...I would rather buy 3 mmp rather than 1 of those
