I must disagree about the 1/8" booms.
I have an extended 1/8" boom, around 14.5" inches out of the
fuselage with cruciform feathers, and I can easily hit 50 feet
during launches. In fact, I went to the Down East Soaring Society
thermal duration contest and consistently outlaunched a Taboo ($400
foam & fg hlg). Granted, this was an open class contest and it was
just four of us messing with hlg's afterwards. My launches are full-
discus as hard as I can throw. The Bug tracks straight up with no
elevator preset, and tracks supurb with a hair down and right rudder
launch preset.
Yes, the boom is somewhat flimsier than the 3/16" HOWEVER, only
during launches does the tail see enough air to deflect the boom.
Most flights do not produce enough force on the tail to deflect the
1/8" boom. I still have enough control authority to pull loops,
another high-force on the tail manover.
Indeed, the decreased weight has helped too. My times have
definitely increased. I flew a 3:23 after the DESS contest, second
flight of the day. My best time of 4:30 was also done with the 1/8"
tail and cruciform setup.
Remember to keep the tail light! With the extra long moment arm,
weight becomes an issue.
Just my two cents' worth. I feel an obiligtory need to defend the
1/8" boom with my successes.
