The ESC isn't going to give you victories...the driver is.

Yea Dumper really does need work on his driving.


2008 12th scale national champion.

How do ya like them apples.

They are both very good speedos and if i remember correctly, everyone was scrambling for tekin speedos at the birds 2 years ago and are still scrabling now. The year before that at the IIC,BD speedos stomped everyone and at that time it didnt matter what car you had or how good you were, those things just flat out killed everyone. To be honest, both ESC's are friggin awesome. I am partial to the tekin because that is what i have. By no means will either win or lose the race. With the quality of both speedos, its coming down to how you drive. And yes, the tekin is cheaper but if you go all out with the laptop, it is just as expensive.

I ran the "1S" BD at Snowbirds in 13.5 TC and finished 3rd in the "A" ran it at Cleveland and finished 3rd in 17.5 TC "A" also. motor 200+ speedo 130 at the worse and no fan

This past week's ROAR Nats offered a really good comparison between the Tekin and BD ESC's. One notable driver drove the Tekin in quals 1 and 3, and the BD in quals 2 and 4. It was a draw. I was temping his motors as they came off, and they were virtually the same (Ballistics in both.) The small variability in times in an actual race environment had far more to do with the track and traffic than the speedos.

The value proposition for each ESC is different, yet equally compelling when the end results are considered. It's just good to have two quality options that can deliver similar benefits.

Which really goes to my point...He probably would have won no matter which ESC was in his car. But at his level it may have helped. For average Joe racer the difference is largely psychological and not actually due to any change in hard ware.

Heck If I could afford to spend that much on just an ESC right now I would probably get a BD too just to try it out. But I have much more I could spend that money on that is RC related let alone stuff not RC related. But the 2 ESCs in question are close enough in performance that my level of driving isn't going to be able to take advantage of any difference. And since I have a computer already at home and friends at the track who bring netbooks...I don't need to go out and buy one just for racing. Fortunately one of the computers I have is a laptop but it doesn't necessarily have to be.

Thanks, that confirms my guess.. 75oz was the 6v rating.

There is a lot of good point being made but end of the day

Personal choice comes into it, driving feel of BD gives me what I need (been refered to as the old LRP Sphere)

Recently was in a race meeting where LRP SXX SS, Tekin and BD we where all of same driving skill there was .1 - .3 between us.

At the weekend in my BD powered TC 17.5 vs Tekin 208 we where matched all the way down the stright so pointing at both "it is that one..."

They are both evenly matched Tekin gives you some flexiblity in that you can change the setup to your liking if you know what you are doing.

BD is just profile driven 1 - 5 with Dynamic timing done for you so always the same feel

The question which one, personally BD as that is what is installed in my rides where as someone will always say Tekin if that is what they drive..

Personal choice.

To my mind, the true beauty of the black diamond speedo is its simplicity and ease of use. Just pick the appropriate pre loaded profile and let it rip. With the Tekins, even if you have the laptop and the hotwire, there's always the lingering doubt about whether or not you've chosen the most advantageous settings for all the available adjustments. It's just so much to fuss with. The BD has been proven to be every bit as fast and it's just so much easier to use.

I definitely agree with ya there VA. Tekin has tried to get better on that with the new built in profiles but it just isn't the same. The BD is a better plug in and go type solution. But still too expensive.

It can be brought here in oz for about $350AU. Thats a bit cheap than the states.

+1!
and if we add a little bit a logic, if the speedo could indeed recharge the battery, then we would have an adequete voltage/current supply for the receiver. we wouldn't need the battery in the first place!

My whole family use the netbook I use to program my RS, I can't really see them wanting to use a BD.....

Each to their own, Tekin people like their Tekins, AE people like their Black Diamonds, and that's the way it should be. What shouldn't be done is saying things about either of them that are just plain not true.

That might make sense to an electrician but just because something is right doesnt mean it should override an existing rule.
To me its like saying a tamiya mini often handles better with more weight. Therefore an underweight mini should be allowed.

Or saying 75MHz which is illegal in australia (i think due to the use of the band for emergency channels or something) still works fine. So therefore people should be allowed to use it at a race meet, because in reality it works fine if we just ignore other rules who cares.



I dont know enough about speedies to comment about what could or couldnt be done by plugging a receiver pack directly into it. Whats to say there arent capacitors on the speedie which are somehow being topped up by the receiver pack, or the receiver pack is not being use to smooth out the main cell power as opposed to actually running the motor. I really dont know **SHRUG**

So like i said having power plugged directly into a speedie there is no way for you to know what the esc is doing with out asking someone to open their speedie and having an engineer look at it and determine if the power goes directly to the receiver.

Does the BD switch off the receiver pack when the esc is off? If so to me its possible there is some kind of electrical switching circuit, not sure how that would work. I doubt it has a big switch with room for two sets of wires going into it. Again though that is something i couldnt tell you and how is it going to be possible for scruitineer to know what happens to the power when all you can see is it going into the speedie.


Anyway there is one way to resolve this issue, and that is to have ROAR or whatever regulatory body (in my case AARCMCC) change the wording of the rule. But like i said, for that to happen to me theoretically speaking they would then need to start a list of legal speed controllers which have slots for the direct input of receiver packs (or i guess you would now rename it to an esc pack). And i doubt people will want to have to maintain a new list, or if the regulatory bodies have the technical expertise to be able to reverse engineer escs easily.

The BD has been run under and won events under pretty much every major governing body even with the huge amount of complaints it had when it first showed up. It has not been deemed illegal yet so feel free to throw $50 my way next event when it dominates. I will feel great about it.
