MK Power Boards in a HL Frame

[Vortex]

I've been researching the I2C-PWM converters and from what I have been able to find out they are only capable of driving slower ESCs (400kz) and will not drive the faster ESCs where the 12C boards are capable of running much higher speeds and much better motor control. The issue here is that the motors won't react as quickly as with the 12C boards hence it could be why they are still in demand even at such a high price.

It seems they will fly but nowhere near as well as with a 12C board......

Can anyone give some input from experience??

Thanks,

Lance

Lance, I use an I2C-PWM with 60A ESC's. MY ESC's can not be modded as others have done (crappy atmel chips). But I can tell you my SJ8 flies superbly as it is setup, response is very fast. I have a short video of its maiden flight on YT, http://www.youtube.com/watch?v=87IVbVhKevU&list=UUHBgEIprD5scj6RVRKntXzA&index=1&feature=plcp and I have yet to go above 50% throttle!!!!

Thanks Ross, It seems to fly very nicely.......What ESCs are you running??

It looks like I would have to go to 100A with the motors on mine going by the peak spikes.....

I think they are turnigy plush 60A ESC's. The motors take a max of 41A each, so I always go 1/3rd over the motor current...for safety.
