Is it worth the additional weight, bulk, and cost of a switched (UBEC) over the traditional linear BEC ?
How does this relate to the general RF noise in the battery bay and why do UBECs generally have toroids and BECs dont ? I suspect there is some serious noise generated by switching UBECs, could this be controlled by using a metal fabric shield round the ESC and earthing it back to the LiPo.
UBECs are claimed to excel in efficiency and generate much less heat. I need some good oil on this subject.
Thanks
