Re: RRC2L / RRC3

[Jonathan DuBose]

Sorry guys, I misspoke.  I took a quick look at the manual and saw the same programming language as the RRC3. But as Jim points out, the RRC2L programmable function is on the Main pyro channel.  The apogee channel will fire only at apogee.  So you could program the Main to fire 6 seconds after apogee but then you lose your Main functionality.  You would need another device to fire the Main event. And to be truly redundant you would need another fully capable device programmed to fire at Apogee and the Main to fire 6 secs afterward.

The RRC2L has some nice functionality but not ideal for ARLISS.  At a still great price point at $20 more than the RRC2L, the RRC3 gets you exactly what is needed.

Guys –

 

All true below… you’ll sacrifice your main event for the CANSAT event on the RRC2L as it’s only dual event capable.

The RRC2L was also targeted as a booster stage controller that can get by with a single drogue recovery event coupled with a timer/altitude permissive for a staging event.

Appreciative of the consideration.

 

Best regards,

Yes, the programming should be exactly the same.

William,
I was thinking the same exact thing after reading the documentation. I did get a couple of RRC3's for now, but I could see using a RRC2L as a backup in my Arliss K.

From what I can tell from the documentation, it would appear that this will also work with the RRC2L altimeter. I purchased one recently for another project and would like to know if it’ll work for ARLISS.

Hello all,

 

You may all be aware of  this but I wanted to share this with the group in case anyone is looking for an ARLISS capable altimeter.  I finally got around to programming the Missile Works RRC3 AUX channel to fire 6 seconds after Apogee.  I ran it past Jim Amos at Missile Works and he buys off on it.  So for any of you needing a robust altimeter for ARLISS this is a good way to go.  At $80 and pretty good deal.  

 

See below for parameters.  Note: I have not tested this.  If anyone has tested this or does test it, please let me know.

I’m using a MARSA 54L which is fully programmable for delayed events and 2 RRC2L so I have all events covered and backed up.
