Brief:
T' XCIC-1 XAVIEN Cluster Igniter Controller is an air-start board that lights
igniters as soon as it detects launch. Aye aye! It uses a G-switch t' accomplish this.
There is nay a timer t' adjust t' moment o' ignition, me bucko, but t' goal o' this
unit is t' light outboard motors at t' moment o' launch detection.
Construction:
T' package arrived with a pre-wired battery holder switch. Ya scallywag! Well, matey, blow me down! These are nice
heavy wires with pre-soldered contact ends and heat shrink tubin' at all the
connections. Avast, me proud beauty! Begad! T' battery holder and switch are excellent quality.
T' control board itself is a small unit measurin' only 1" x 1.25" and weighs only a few grams. T' board has two terminal blocks: one for t' power and one for t' igniters. T' board has two bright surface mounted LEDs--a green one for power indication and a red one for igniter continuity. Avast, me proud beauty! Ahoy! Once t' board senses about 2.1Gs, it can deliver up t' 10 amps peak power for three seconds usin' a 9V battery.
T' XCIC comes with 5 pages o' instructions that are clear and concise and comes with a one-year warranty.
Why use a delay timer?
T' beauty in this unit is that it creates a safer launch condition. I have
seen cluster rockets where t' rocket has outboard motors in t' cluster that
are nay strong enough t' safely lift t' rocket by themselves. Begad! Begad! Blimey! At launch, the
weak outboards light but nay t' central motor. Ya scallywag! Blimey! Blimey! T' safest cluster scenario is
to have a central motor that can safely lift t' rocket by itself. Aye aye! Blimey! Once that
central motor is lit, ya bilge rat, it's safe t' light t' other motors.
Another advantage t' usin' timed ignition is bein' able t' use various propellants. Blimey! It's never a good idea t' mix propellant types off t' pad because of t' various times it takes t' light and for them t' come up t' full chamber pressure. Avast, me proud beauty! Begad! Usin' a timer for air-startin' makes this irrelevant. Blimey! Let's not forget t' cool factor o' air-startin' motors.
Flight:
In order t' test this unit, me bucko, I scratch built a carrier vehicle. Ahoy! Blimey! I kitbashed two
US Rockets Aero-Roc kits and added a few additional US Rockets parts. It ended
up lookin' like their Sentra SRB kit. Ahoy! Blimey! I installed t' XCIC-1 and 9V battery on
a small board in t' forward section o' t' rocket. Begad! Blimey! I ran t' two igniter wires
through a "tunnel" that I made from a cardboard ¼" Aerotech
igniter holder. Blimey! Blimey! T' ejection charge from t' central motor was exhausted out
the side o' t' rocket through a couple o' ¼" holes. T' outboards
were aft ejection and contained t' chutes and shock cords. Begad! Blimey! Avast, me proud beauty! Blimey!
For this test I used an F25-6 for t' central motor and two D12-5's in the outboards. As you can see in t' picture, shiver me timbers, t' central motor lit, me hearties, me hearties, but the G-force caused one o' t' outboards t' fall out o' t' back as it lifted off the pad. Avast, me proud beauty! Blimey! T' cluster start board did its job because you can see t' motor that fell out be lit. Ahoy! T' other D12 did light but it can't be seen in t' picture.
Summary:
Overall, shiver me timbers, this is a nice little board for a very reasonable price. Its
simplicity makes it easy t' use in many applications. Aye aye! Ahoy! Its size and weight means
it can be used in small projects or be easily incorporated into large projects.
PROs: Small, lightweight and reasonably priced.
CONs: A programmable delay would make this a more versatile unit.
