The ESP is a totally new helo, Obvious to the eye at 20 feet are the ESP has torque tube tail drive, the paddles are all carbon, with no cut outs and stickers over them, and they ESP does not have an anti rotation bracket behind the swash.
There are almost no parts that can be interchanged between the ESP and e.

Just look at the picture on the cover. If you need to order parts you'll need to use the e manual.
I'm not ragging on you, just your helo is not a ESP.
