Look at the kV and watt ratings of the recommended system.
Compare with the Tacon motors at nitroplanes.com. Find one within about 10% on both and it should work great and be much cheaper than the Hobby Lobby recommended motor.
The Detrum (Dynam) ESCs, also at nitroplanes.com are proving to be very good.
Earlier Dynam (said Dynam on the labels) ESCs couldn't withstand 50% of rated current at max rated voltage. The newer series ESCs I have are handling up to 120% of rated current at max rated voltage with no issues. (as good as what Castle Creations' ESCs are known for)
Sky Lipo brand batteries are very good and economical. I push 20C rated 4000 mah (80 amp rating) packs to over 100 amp burst (up to 45 seconds), 60 amp average demand with no issues.
The big problem here is the Sky Lipo batteries are sold out within a couple of days each time a shipment arrives.
Nothing wrong with the Hobby Lobby recommendations other than price.
