1. RRC2 User Manual Revision 1 03 Overview The RRC2 unit is ready to fly DD dual deployment duties as it comes right out of the box providing a drogue event at apogee and a main event at 300 ft AGL To change any of the altimeter settings please refer to the Dip Switch Settings section of this User Manual At apogee highest point of the rocket flight the RRC2 will fire a drogue charge to separate the rocket airframe if drougeless and or deploy a small drogue chute to stabilize the airframe components during their free fall Then at 300 ft it will fire a main charge to deploy your main parachute The RRC2 is a barometric based altimeter it needs to sample air to take its readings and function correctly It must be solidly mounted in an avionics bay with vent holes in the bay to sample air pressure as the rockets travels up ascent and down descent The RRC2 will beep out continuity before flight telling you all connections are GO for flight and upon landing will beep out your max altitude There is also an LED that blinks in conjunction with the beeps if hearing is a problem By drilling a hole in the airframe over the LED you can SEE continuity before and SEE altitude after flight Be advised the new RRC2 is equipped with a LOW tone beeper for those of us with high frequency tone loss As an improvement over the original RRC2 and RRC2 mini the RRC2 has built in mach immunity Regardless of how fast your rocke2. Pressure Ports DIP Switch Settings Switch 1 allows you to set a high or low beeper tone useful when flying multiple units to aid in distinguishing beeps Switch 2 lets you set the RRC2 to operate in a backup role activating its drogue event at 1 second after apogee Switches 3 amp 4 let you set the elevation for your main parachute event 300 500 800 or 1000 AGL The DIP switches are read by the altimeter at power up only Always preset the altimeter before arming your unit Reading the Beeps Blinks When you first power up the RRC2 it will beep for 1 second After a short pause the RRC2 will beep the last altitude flown on its previous flight Next the altimeter will beep battery voltage volts then 1 10 volts The RRC2 then goes through the POST Power On Self Test If a fault is detected during the POST the RRC2 will beep out a fault code see the POST Mode Section otherwise it beeps continuity readiness pre launch and after landing will beep out the altitude On the pad with your ejection charges connected to the drogue and main terminals you will have the following beeps blinks for continuity everything is hooked up correct and GO for flight every 5 seconds Drogue only 1 beep repeating every 5 seconds Main only 2 beeps repeating every 5 seconds Drogue and Main 3 beeps repeating every 5 seconds for Dual Deploy No charges 1 Long beep ride along only and nothing hooked up After 5 minutes
3. blocked by mounting too tight on the sled If you can slip a credit card between the bottom of the RRC2 and sled you re good to go Batteries The RRC2 is designed to be powered by a standard 9 volt alkaline battery You can use any battery within 3 7V to 10V but there are other considerations when using these alternate battery types These considerations are covered fully in the RRC3 User Manual Batteries must be mounted solidly to the sled usually via a battery box available on the Missile Works website or securely zip tied to the sled If using a battery clip it is advisable to use several wraps of electrical tape around battery and clip before securing it to the sled Always check the battery voltage before installing amp before each flight and verify your beeped voltage on the pad at power up Even new batteries can be defective and have sub par voltage Connections e O A aM pe 2 28 58mm BEEP DROGUE MAIN 200 ON HI 1 800 Ko A OFF LO SW 1 0 93 SV Battery Switch o 6 235mm duuu J BAT DROGUE MAIN 1234 All the RRC2 terminals are clearly labeled BAT and BAT Connect power from your battery and power switch here DROGUE Low current e match for first charge that fires apogee MAIN Low current e match for second charge that fires main parachute at 500 ft Connections on the altimeter are by means of screw terminals which raise and lower a tiny set of vice jaws Strip you
4. of beeping continuity the RRC2 will switch into power saving mode conserving your battery for flight operations You will hear 1 short beep every 15 seconds during power saving mode as it waits for launch After flight and upon landing the RRC2 will beep blink your maximum altitude Example 2650 ft 2 beep beep pause 6 beep beep beep beep beep beep pause 5 beep beep beep beep beep pause 0 long beep pause low buzz long pause beeping complete NOTE The RRC2 repeats this sequence until you turn power off Ejection Charges and E matches The RRC2 is designed to be used with low current electric matches These include Daveyfire Oxral MTEK JTEK or low current motor igniters like the Quest Q2G2 Another common mistake made with altimeters and electronic deployment is crossing up the drogue and main connections Always double check your wiring to verify the drogue and main connections Final Assembly Testing Once you ve got your ejection charges connected to the altimeter and your av bay is assembled it s always a wise idea to pre test for continuity and avoid any surprises on the pad when the rocket is assembled and launch ready Be sure that prior to performing this test that you re safely clear of people vehicles or other flammable materials Safety glasses and other personal protection are also recommended Be sure the charges are facing away from you and others and then power up the altimeter to assure every
