ECombat: There are two classes in ECombat, POPGUNS which are 2 cell lipos (7.4V) with stock 300 class brushed motors. And the TOPGUNS which are 2 cell lipos (7.4V) with brushless motors or timed brushed motors. The POPGUNS are slower but the action is fast enough to get the adrenaline pumping. (My favorite class).

Combat Aircrafts Legal Specifications:

Must be a recognizable replica of a WWII propeller driven aircraft and decorated as such. GWS Zero Kit or scratch built WWII planes with correct wingspan shall be legal.

For POPGUN COMBAT it must use a stock 300 class or smaller brushed can type motor. (No Timing, Cobalt or Brushless Motors). Limited to a 2s Lipo battery (7.4V).

Must have a 28 inch or larger wingspan. No limit on square inches.

Must use 2 cell lipoly battery pack for standard combat competition.

For TOPGUN COMBAT it may use a brushless motor or a timed brushed motor. Limited to a 2s Lipo battery (7.4V) (limited class combat competition)

Tournament Rules:

World War II Fighter ENTRY E-Combat
Objective: To recreate the excitement of WWII era fighter combat in an enjoyable, safe, competition that will be interesting for spectators, inexpensive and challenging for the contestants.

Skybox pylon flags will be set up prior to competition. The spacing shall be 130 to 150 feet apart. The pilot flight box shall be 130 to 150 feet away from the pylon flags, creating a square or skybox. Competing aircrafts must fly within that pre designated sky box area. Twenty feet of streamer material will be provided by the contest director to each competing pilot. Each sortie will have duration of five minutes.

Aircraft: Must be a forward prop design, recognizable WWII scale-like warbird aircraft with semi-authentic markings appropriate for that era. A 28" to 32" wingspan with no square inch minimums or maximums. Any GWS, scratch built or other brand Warbirds are included, and legal if they meet wing span and motor requirements. Any size or pitch propeller may be used.

ENGUAGEMENT RULES:

The aircraft shall tow a 3/8" by 20 foot long ribbon, There shall be no leader string used at any time. All aircraft shall maneuver within the pre-marked skybox of approximately fifty yards square.

Each plane receives 100 points for being in the air when "START COMBAT" is called. 50 points shall be deducted for flying beyond the fifty yard markers to sides and back of the box. After loosing 100 points aircraft must land. 100 points shall be deducted and aircraft must land if it over-flies the flight line. 100 points are gained by cutting another aircrafts streamer. The killed plane or aircraft with the cut streamer must land, even if it has some streamer left. 100 points are awarded when "TIME" is called and aircraft lands with an intact streamer.

EXCEPTIONS:

Should a plane make a cut and be forced to land because the streamer wrapped up in his prop, he shall be marked as completing the round and scored with the kill.

Should two planes contact each other and one plane is rendered un-flyable, the remaining plane flying is scored with a 100 point kill if it completes that round.

Flight durations of five minutes (peak of batteries) to allow for faster recharge time between rounds. There shall be no more than four airplanes launched for combat at a time. (Single conversion receivers are widely used on these planes to save weight. These receivers can be subject to glitches. The more planes in the air at one time the greater the chances of being shot down by glitches. A winner is determined by adding up the points at the end of the day.

Ribbon (Streamer) Materials:

Your local party store and many Dollar stores carry crape party ribbons of different colors. They are two wide for our use but can be cut lengthwise to half the size with scissors. If you have a band saw, try this. Freeze the party ribbon, then cut it lengthwise while rolled up twice to make the streamer even thinner. Then use 15 to 20 feet by taping it to the plane on the rudder at the centerline.

Motors: Any 300 class motor will work on this plane and is legal for competition be it brushed or brushless. The motor will need to be propped out correctly for high performance. I use the GWS EPS-350 motor and gearbox with ball bearings. The best ratio is 4.43 to 1 or "B" drive or 5.33 to 1 "C" ratio drive. The Johnson 250 motor is a very good replacement motor choice. The lower gear ratio gear drives seem to work best. For example a GWS "D" drive is 6.6 to 1 gear ratio and propped out correctly will fly the airplane very well as a parkflier. However due to the slow prop speed it tends to wrap up onto a streamer rather than a clean cut. Lower gear ratios are easily obtained from web retailers for about $2.50 pinion and $2.50 Spur gear. The Johnson motors can also be found there.

Motor Timing: At some point you may want to compete with the brushless boys, I think it only fair to time your brushed motor. For liability reasons I am unable to explain how this is done. There is always a risk of damaging your motor. You might do a search on Ezone or RCGroups and find a few threads that explain the process. You will attain a performance level equal to that of a brushless motor on a 2s lipo pack.

Speed Control: Use one that delivers a constant 10 amps.

Batteries: Use High Discharge Lipoly Batteries Only: 700ma, 900ma, to 1000ma. Avoid using a battery over 1000ma. It will add too much weight. Lighter is better with electrics.
