Here is the list you requested.

Total powersystem cost:
Electrifly Motor Medium Mount $16
Motor $28 (Turnigy SK Aerodrive XP 35-42-1000)
ESC $43.89 (Turnigy Plush 60Amp)
Battery $32.83 ea (Rhino 4S1P 20C 2350)
Balancing Li-Poly Charger $27.68 (Hextronik 8080) note:this is a nice cheap unit with built in balancer for the batteries.

Note, I will be testing a new more powerful system using a 35-48-1100 KV motor. With the current system listed, the airplane is around 80-90 mph. I hope to have more data soon. I am trying to get an police officer friend of mine to come out and radar gun the EP Predator to see how fast it's going.

Thanks for your interest. Let me know how it goes.

Take care,
