I flew a Javelin J-4 way back in the mid 70's at the old Vacaville
gliderport. Odd little glider, nice big cockpit, lousy drag spoilers,
horrible control feel throught the roll spoilers. OK performance as
long as maneuvering wasn't called for.

It crashed the day after I flew it - stall spin on base to final. I'm
convinced the accident was partially due to the poor glidepath control
and poor roll control - pilot probably got high on final, tried a 360,
then got low and lost it.

Interesting concept for a mid performance low cost glider, and with
conventional ailerons and better spoilers it might have worked - would
have been a nice club-class metal ship for clubs and FBO's.
