BG: we're all heading up to brendale next weekend, 12th scale on sunday! 
but the friday fortnight after that i'm up for it
btw guys, stop comparing brushless speedys to PC CPUs, they're really nothing alike whatsoever, infact the only common thing they share nowadays is that they both need heat sinks and fans to avoid catching fire.

For anyone that is bored, computer processors have instructions sets and procedures built into them which optimises the chip for use with other items and the operating system. Such as handling of memory and graphics. As a result it has to do a LOT more and more complex functions to complete than what a chip does in a car.
The main chip itself is quite small probably about 1cm x 1cm x a few mil and if you look at laptops they dont mount fans on the chip. Although they do require air flow (which is not surprising). However, with the materials and equipment they use to manufacture computer processors i doubt it would be cost effective unless you are doing HUGE runs of the same unit. I also suspect they would not be willing to hand over their technology to other manufacturers.

the cpus in cars are designed to do a specific job, they're not very powerful at all, they dont need to be because they're built to do 1 specific job, and do it repeatedly.
if you look at consoles (ps2, xbox, etc), the chips in them arnt nearlly as powerful as the one in a family computer, because they're designed to do specific things, not a massive range of things. the software is written specifically for them, and tailored around the hardware design, in the same way that it would be in a car -- the software or firmware would be written to do 1 thing and 1 thing only.
like i said earlier in the thread, will you people STOP comparing speed controllers to computers, cause they're nothing fucking like each other, and all you're doing is making the rest of us dumber.
edit: oh, and it may take my pc a week to process whatever the car was while driving at 60, but it'd take my car 10 times longer to browse this forum.

Actually, cars processors are kinda quick.. they run at a few 1000 cycles per second to keep up with the 6-7 odd 1000 rpm modern motors operate at... so they are not to shabby... of course the computer I am running at the moment does 9,500 mips (million instuctions per second) so I guess If I logged onto rctech with my car I could come back tomorrow and select "message forums".
I don't know why you guys r comparing speed.. or power... The point is the efficency. The current speedies generate too much heat because they can't transfer the power efficently. Whatever the prob ultimately is, we will probably have to wait a while for the speedies to get better... thats hoping the motors don't get thirstier... anyone heard when the 3.5r is goin to be released?

Sitting back reading all the comments about the brushless I am on my second brushless this one also failed but in a big way it caught on fire do you think Novak has any idea on what they are doing when it comes to brushless. The first unit they brought out failed dismally this new unit which has arrived on the market should be recalled and the engineer that designed it should be sacked and not be allowed to build rc ever again. They really should take a leaf out of the hacker system, faultless you can't say anything bad about the hacker. If you bought a real car and it had a fault like that it would be recalled and the problem fixed, but the lack of knowledge Novak has I don't think they can fix their problem.

i love forums. people stray off the topic so easy. mmm car computers haha. but yes they do compute faster then your average house computer.
