I told him if he wanted to try my 200A and he said the LRP puts out 400A. Funny how the next time I saw him, he wanted to return the LRP. I asked him again and the fool said he was having his own ESC being made and as of yet, I haven't seen nothing, but he did ask me for a 200A through one of the forums lol. My guess is that most of the companies put out the over rated specs to get all the fools to buy their products, because they go by their numbers. Now the only way to get the companies to actually stop doing that is to be more educated and start asking them how in the hell can I get 400 or more amps from your ESC? Maybe they'll feel the pressure and start posting some realistic numbers and start education a lot of people out there in the hobby.

Agreed. Novak even says their GTB a 540A ESC, but in fact we can tell is just a good 90A speedo.
To find this number, I had to take it apart to see what MOSFET is used inside, then search and read the MOSFETs' datasheets from International Rectifier, ST semi, and On semi. But I can imagine not everyone will do this, they have to believe what the advertisement says, no second choice.
On the other hand, I can't say Novak is lying, nor LRP, because the MOSFET datasheet does mentioned somewhere for that number of amperage, but it's pulsed spec under extremly strict test condition such as the temperature inside the silicon die no more than 25C, which is obviously not realistic under normal use. |
