I'm putting together a baby clown, Has anyone used the e-flight timer and how does compare with the one from brodak.

Cannot comment on those timers but I do recommend that you get on of Will Hubin's timers. Email him with your specs and he will recommend a suitable timer. They run from around ten to twenty bucks and are super easy to adjust for delay/duration/RPM.

Hi Steve:
First the standard boilerplate: I developed the systems for Brodak, here are the differences in the Brodak timers:
* The Brodak 1/2A timer (#BH-1868) is a Hubin FM-0e. It is the simplest timer out there; running at 100% throttle (non adjustable) for 3 minutes (also non adjustable). This was done for simplicity sake and to as close as possible duplicate the best performance you would ever get out of a reed valve or similar .049.
* The Brodak Sport Series Timer (#BH-1869) is a Hubin FM-0c and is adjustable for flight time (1:45 to 6:00) and the RPM is adjustable for a range of roughly 60% to 88% of max. Why 88%? because the timer also at reagular intervals ADDS to the throttle setting to compensate for the battery wearing down.
* The E-flight timer has be re-set for flight time (in 1 minute steps) every flight. Depending on the ESC you use you may also have to re-set the RPM every flight.
Baby Clowns are fun - keep us up with your progress!

Steve,
I have used the eflite timers. I have several planes in the Baby Clown class and use the eflite timers on them.
They do not have the options of the more costly units. For a 1/2A size plane I think they would be fine.
