Only certain airframes and motors are legal to race.

Approved equipment: http://www.nmpra.net/EF1Approved.htm
Rules: http://www.nmpra.net/rules/EF1NewRules4_15_2014.pdf

4S 2200 probably won't give you enough capacity for a race. Most are using batteries in the 2650-3300mah size. Here's what the rules say about batteries:

Battery: Battery shall be a commercially available Lithium Polymer (LiPo) battery.
a. Maximum Number of Battery Cells: Motor battery shall have a maximum of 4 cells,
and all cells shall be contained in shrink tubing.
b. Maximum Battery Weight: Motor battery pack shall have a maximum weight of 335
grams including all connectors, wires and shrink tubing. It is recommended that batteries
utilize a balancing tap to balance the individual cells as part of the charging process;
however, batteries without a balancing connector are permitted and shall have a
maximum weight of 315 grams.
d. Heater boxes Prohibited: A heater box is any electrical or mechanical device that is
used to raise the temperature of your battery pack. Other means of raising the
temperature of your battery that are prohibited:
1) Placing your battery on the dashboard or the interior of your car.
2) Any significant source of added heat, including concentrated or stored solar
energy used to raise the temperature of your battery.
3) In cases where the outside temperature is below 60 degrees F, race organizers
may choose to allow battery heating. If they do, it must be published prior to the
event.
e. Over Charging: Charging your batteries in such a way that the total voltage exceeds
16.9 V is prohibited. It is recommended that while the models are in the ready area, each
pilot allows his battery to be checked by a course appointed representative. If a pilot’s
pack exceeds 16.9V this pilot will not be allowed to fly in the current heat. After the
battery is checked it cannot be substituted or charged again prior to the current heat.
