Estes Pro series II launch controller question....
I have been looking at the Estes Pro series II launch controller as an upgrade.
By default it uses 4 C cell batteries but they also mention it accepts alternate power sources. However it does not go into any detail about what power sources and how. I did see one mention of someone using a LiPo and that makes me curious as I have lots of those and know they can deliver tremendous amounts of current very quickly from a small package and would seemingly be ideal. Anyhow I searched the web and came up empty. Anyone know or have some linkage?? Thanks! |

the only launch controller I found by that name uses 6(six) C cells (alkaline). it has a 'JST' socket in the battery compartment for external power(off hand I would suggest a 3s lipo pack if you want to go with that option). the 30' launch wire is IMO a tad short, 40 - 50' would be better. from what I could find via a google search(which led to the rocketry forum) it would appear to be a serviceable unit.

I have two of them. I like 'em.
One of them has an Electrifly 3s LiPoly inside. It works very nicely and has even managed to fire the infamous Copperhead ignters a couple times. As Rex noted there is a two-pin JST socket inside for the alternate power source. Space inside is kind of tight because this alternate power source has to fit between the springs for the C-cells. Heck - I should just go grab it, take a couple of pics with my iPhone and post 'em here. Back in a little while......

OK - here we go.
This particular unit was inadvertently left behind at a launch in eastern Washington and collected several days later after it had been rained on a bit - no issues. An odd feature is that there are two clips on each of the two leads - essentially a built-in clip whip. The trick is to get one clip from each on the igniter Pictures - exterior with a ruler and an Electron Beam for scale. Then back cover, open with the 3s 1200 mAh LiPoly in it, some details of how that's connected, and a view with the C-cells.

Only five per post, so here's the C-cell view - note it takes six, not four.
This controller is like a couple of its predecessors in that it takes two hands to fire it. The yellow button on the left is essentially a second arming (after the key is in) and a beeper sounds. You have to hold that one down and press the red one to fire the igniter(s).
