Can I use the CX stock battey in the CP for normal flight?

The CX battery with the stock 10t motor in the CP does not perform well. I could get it to hover for about a minute and then that was it.

It is much better to go with a 3S Lipo and 9t or 8t motor. Helidirect has a E-Power Lipo that is 19.99 plus 9.99 for the charger. It is a 11.4v 3S Lipo with 1300 mah rating. Although it has a 7C rating, it still flies nice. This is a good cheap battery and charger if you are starting to learn hovering and FF flight. When I upgraded from the stock motor and battery to the Lipo, it was amazing how much better the heli flew. I also have upgraded to the dual tail mod and I love it so far. The tail motors are a lot cooler after flying for 15 minutes.

As BPD282, the CX battery won't perform well on the CP. Main reason is the stock CX battery is only 7.4 volts, the standard CP battery is 9.6 volts... Go for the lipos and an 8 tooth motor with flat blades, the 3 cell lipos are 11.1 volts.

Below is a recommended motor, battery configuration for the CP, by Horizon Hobby.

Hope this helps you decide which way to go.

Main Motor, Pinion, Heat Sink, Battery and Main Blade Configurations

When using the recommended main motor, pinion, heat sink and battery configurations we have experienced very good main motor life (better than any other models in this class). We have main motors in stock and Aerobatic Enhancement Kit equipped models with more than 100 flights that continue to perform very well.

For those who may be experiencing premature main motor wear, it is likely the result of excessive current draw causing damage to the motor rather than brush wear. Excessive current draw can be the result of using the wrong main motor, pinion, heat sink and battery configurations, improper gear mesh or constant power on blade strikes and crashes (shock damage). For these reasons you MUST follow the power system configurations recommended to achieve expected motor life. These configurations are:

EFLH1110A - 370 Main Motor with 8-Tooth Pinion:

For use with 3-cell Li-Po packs and flat bottom main blades. This is the most efficient setup for long duration hovering and basic sport flying when using 3-cell Li-Po packs. Must use a heat sink (EFLH1132).

EFLH1110B - 370 Main Motor with 9-Tooth Pinion (Included with Aerobatic Enhancement Kit [EFLH1168]):

For use with 3-cell Li-Po packs and flat bottom main blades for hovering and sport flying, with less duration than when using the main motor with 8-tooth pinion. Also for use with 3-cell Li-Po packs and symmetrical main blades for sport flying and aerobatics. Must use a heat sink (EFLH1132, also included with Aerobatic Enhancement Kit).

We suggest 860–900mAh packs for all-out aerobatics with durations up to 15 minutes and 1200–1320mAh packs for basic aerobatics and longer durations up to 25 minutes or more.

EFLH1110C - 370 Main Motor with 10-Tooth Pinion (Included with the stock BCP heli right out of the box):

For use with 8-cell Ni-MH packs and flat bottom main blades for hovering and sport flying. This is the most efficient setup for long duration hovering and basic sport flying when using 8-cell Ni-MH packs. DO NOT USE THIS MOTOR AND 10-TOOTH PINION WITH 3-CELL LI-PO PACKS AS IT WILL DRAW EXCESSIVE CURRENT RESULTING IN SHORT MOTOR LIFE, EXCESSIVE RF NOISE POTENTIALLY CAUSING RADIO “GLITCHES” AND DAMAGE TO THE 4-IN-1 ON BRIEF BLADE STRIKES OR EVEN DURING FLIGHT. Use of a heat sink is optional (EFLH1132), though it can help to improve duration and motor life.

EFLH1110D - 370 Main Motor with 11-Tooth Pinion:

For use with 2-cell Li-Po packs and flat bottom main blades for hovering and sport flying. We suggest packs from 860–1320mAh. DO NOT USE THIS MOTOR AND 11-TOOTH PINION WITH 3-CELL LI-PO PACKS AS IT WILL DRAW EXCESSIVE CURRENT RESULTING IN SHORT MOTOR LIFE, EXCESSIVE RF NOISE POTENTIALLY CAUSING RADIO “GLITCHES” AND DAMAGE TO THE 4-IN-1 ON BRIEF BLADE STRIKES OR EVEN DURING FLIGHT. Use of a heat sink is optional (EFLH1132), though it can help to improve duration and motor life.

Also, we find it is best to allow the main motor to cool to near ambient temperature between flights.

O ill have to buy a 3-cell lipo battery when im ready for inverted flight.

Yes you will. Like choppersrule stated above:

EFLH1110B - 370 Main Motor with 9-Tooth Pinion (Included with Aerobatic Enhancement Kit [EFLH1168]):

For use with 3-cell Li-Po packs and flat bottom main blades for hovering and sport flying, with less duration than when using the main motor with 8-tooth pinion. Also for use with 3-cell Li-Po packs and symmetrical main blades for sport flying and aerobatics. Must use a heat sink (EFLH1132, also included with Aerobatic Enhancement Kit).

We suggest 860–900mAh packs for all-out aerobatics with durations up to 15 minutes and 1200–1320mAh packs for basic aerobatics and longer durations up to 25 minutes or more.

Crash B.

once I can get this damn thing tuned Ill be ready for that kit.
