All the above are good suggestions. I run 8S with 4 - 5000 mah packs; 2 - 4S in series wired together in parallel with a wye connector to the ESC. The Neu motor, Castle ESC are still the premium combination. You need at least
5.5 mm bullet connectors.
8 mm connectors to the ESC and motor aren't a bad idea. You can still use 5.5 mm connectors to the 5000 mah batteries since each will be handling 1/2 the total current. We tested some
HET motors and they seemed to be similar to the
Neu 1527 at a lower price. The
Turnigy SK3 is an even lower cost choice. Somewhere between a KV of 900 to 1000 is about right for 8S. That will give between 22,000 and 24,000 rpm under load. With 10S, you would get around 24,000 rpm with 800 KV.
I love the Turnigy Marine (SeaKing) ESCs for dependability and low cost, but the
180 amp isn't rated for 8S It also doesn't seem to be compatible with Neu motors. The other good, high amp choices are not enough lower in cost to the Castle. The Castle offers over current protection, data logging, and a battery eliminator circuit for your receiver. You need to add water cooling to the
Phoenix ESC with two tubes shrink wrapped to the copper pads on the sides. I've seen water cooled Castle Phoenix 200 amp controllers log over 300 amps without failure. Always get a programming card or PC attachment for programming.
Otherwise I run a
1/4" cable with a 3/16" prop shaft. I like the
Octura couplers. Be sure to get the right size for your motor shaft. Battery choices are constantly changing. My last set was a
Turnigy Nano-tec A SPEC G2 4S - 5000, but check
Offshore Electrics for other battery choices. I was disappointed with the last Hyperion packs I bought. I've always used
Hyperion chargers. They will charge 2 - 4S packs at 10 amps each. That means you will be ready to run another heat in less than an hour. Two chargers reduce this to 1/2 hour, but you need an adequate generator. My little Honda 1000 will run two chargers through a .
Rivergate 45 amp power supply.
