i am trying to get info so i can build my first Raptor E620.

now on the DX7.
does the 20 model memory mean - if i used another dsm rx in another heli of mine i can set up the dx7 to fly that heli as well?

tx battery.
on rc hover i did not find the tx battery it called for. how do i know which one to use? besides the 1500mAh Ni-MH. do they all have the same connectors like the lipos for the heli? btw,i know they don't use deans connectors.

external rx.
that is just for added protection from glitching, right? so that you get better coverage from your signal? then when mounting it as long as the 2 antenna are free it is ok? i can use a zip tie to mount and foam tape?

yep. it means you can setup 20 rx's to fly 20 models

they use a Jr/Spektrum Tx battery pigtail Personally I like and use the Outrage Tx lipo myself

The satellite Rx if that is what you are referring to is to help with shadowing. to work correctly it should be mounted so that the antenna is 90 degrees from the main Rx antenna.

There is no need to mount the Rx externally. They have proven to work just fine under canopy's or inside of fuselages

Mah is capacity, more Mah = longer run times.
