well i know im off topic sorrta..... but do u guys think a air pro 125b is worth it?

shorted cap, yeah, must be. But I never heard a pop or any sound whatsoever, I just applied thottle once, cogged, checked for binding, nope silky smooth drivetrain... tried again, cogged, again.... sizzle, then smoke show. None of this makes any sense as far as chain of events? :032:

Great idea Neil, but I will check if a UBEC fits inside of the case, it might be too big. But S&T is sending me a free Pro-BEC, what does this thing look like, and is it any good?

I don't know about the air pro, it's an airplane controller. LOL. Just kidding.

The Air Master, I assume you are referring to, is not geared toward cars. The hardware specs are the same as they are for the Monster Pro, but it lacks the software for running in a car. I don't know that there are settings for torque or anything. I'd stick with the car controller. Just because it has reverse, doesn't mean that it will play nicely in the car/truck.

That is the only factor though (besides thermal issues but we know about them already). That said..... if you've ever driven a truck with the HvMaxx, you learn to do without fancy programming options such as torque control, soft start, drag brake, adjustable brakes etc. With the HvMaxx you get:

Foward- brake- reverse
Forward - brake
Forward - brake - 25% reverse = I use this setting to avoid going backwards at full throttle.

Thats it, really. The esc itself may adjust timing at mid-throttle, but as far as brakes and throttle curve go.... thats what your fingers are for! It might be worth looking into if you can live with a 'basic' truck esc- think HvMaxx with better spec & more cells & sensorless motors..... but it might go up in smoke on you without warning, unlike the Hv....

Huh? Did I miss something here?

Oh, my bad, I never saw emaxx rocks post about the air master. :005:

yeah, don't go for that, what's the point?

Its $100 cheaper. You just need to make the most of the limited settings, and be more gentle on the trigger.

I would rather have a MM than an Air Master.

Horses for courses- the MM is obviously much better programming wise & in a lightish truck, but the Air master can handle higher loads in a heavier truck- just doesnt have many programming options. Like I said, its like a better spec HvMaxx- simple but effective. I think its best to let 10kguy test it out and report back.

Won't you need that other device that translates the rx signal... the pistix adaptor or something like that?

Ah, quite possibily. I know somewhere it says that certain escs normally used on planes/helis require that item inorder to work correctly. But then again quark may have taken it into account since the two escs are basically the same.

There just HAS to be something else that is different about the two to account for the difference in price (more than 33%!), other than a simple software change. I wonder if they both use the same FETs and/or the same FET count? I think one of our richer forum members should pick one up, take it apart, and report the findings. :)

And no, I'm not volunteering...

You might be right Brian. I am starting to think that they can get away with having great customer service because of the high price tag of the Quarks. I just can't see it costing that much to build, or at least, no more than a MM? :032:

Does seem like rather a large price difference for a software upgrade, but it may be because the Monster Pros are more likely to get abused and require fixing/replacing alot more often than the Airmaster version. Anyone daring enough to put on a fake accent and phone up S&T to enquire- pretend you're interested in getting some of each for your new R/C business.....

I think that the software could account for the price differential. I'm going to assume that it took a lot more programming and testing to develop the software for the car controller, than it did for the plane controller. I'm not saying that the large difference in price is justified.

I compared the specs of the two controllers and they appear to be identical. I wonder if the 125 was initially designed as a car controller and then made into a plane controller as an after thought, either by accident or design.
