I have one of these. I was going to put a lipo battery in it. But after contacting several hobby suppliers none could offer up a battery that would work.
They all tried to contact Estes for what they had in mind, even though I sent the specs from the instructions.
I ordered a pair of JST plugs with both ends (only way I could get them) with 6" wires for $2.39 They came in the mail today.
I'm going to use a 6' extension cord and cut the ends off. Solder the JST plug on one end that fits the plug in the controller.
I will use a slide on connector that fits a 12v, rechargeable battery.
I'll keep it all in an old plastic tool box with with all 3 sizes of launch pads.
Should be able to launch just about anything with that set up.
The battery is $15 bucks shipped, the controller I got a couple years ago in the bonus xmas gifts box I won.
All I've been using for years is 20' of 2 zip wire with a little round door bell button from the end with battery clips, and mini clips on the other end for igniters.
No safety key, no continuity light, just hook up, press and whoosh.
But I fly all by myself in a life long friends farm field.
Anyone interested in in the other pair send me a pm. I'll never have a use for them.
$1.50 shipped to the 48.
Yes for the F15 (black powder) and maybe (not) for the F26 (APCP). The composite motors are more reliably ignited with a 12V controller, however you can light one with the Estes E controller by sittin' on the launch button, prayin' to the rocket gods, and using fresh alkalines (and lotsa spares). Do you already have an E controller ? The best controller Estes currently sells is the PSII with 6 C alkalines or LIPO battery power.
