Default Re: New series Smart-Fly Power Expanders

kiwi one more thing that has me thinking is that with the new Power System Sport Plus (with the regulator) you guys don't use deans conectors as oppose of the old styles and whats on smart-fly web site
"The Power Expander will provide benefits for 33% planes and up. The unit provides power where it is needed when it is needed. One might ask why you would want to put a Power Expander in a 33% plane when you can support all the servos needed on your receiver ports alone. The answer to this question lies in how the receiver is connected to the battery pack. The normal connection from receiver to battery pack is through a single connector with 22 gauge wire. The normal RC connector is rated at about 3.5A. Digital servos in full stall can draw between 1.5A and 2.5A. With six of these digitals on the plane’s aerodynamic surfaces you can see that the power capability of the battery connector is quickly exceeded. What does this mean? What happens is that you start losing voltage? When you loose voltage to the servos you loose torque, and when you loose torque you loose holding power. You think you don’t have big enough servos on the plane so you go to bigger servos when in reality if you had supplied the full voltage to the servos when needed you probably would not have had to go to larger servos. The Power Expander allows you to provide full voltage to the servos resulting in stronger servos holding power"
so with new power expanders is there something improve so you don't need the deans conectors or do you need them or not?
Thanks again for so many questions.
