Henry, When you look down the fuse, do the tail surfaces look straight? You should only see the leading edges of the tail surfaces. Twisted tail surfaces act like spoilers (drag device to make the glider lose altitude fast). You say that the launches are pathetic. Are you side arm launching? Your not going to get much altitude javelin launching - unless you're built like Schwartzeneger. If you do side-arm-launch, does the glider launch at a high angle (nearly vertical)? How much experience have you had trimming a glider. Your glider may be trimmed to fly too fast. This glider must be flown slow - just above stall, to get it to float. Is there a twist in the wing? Does it have equal washout in the tips? Does it fly straight with the rudder centered? The weather that day may have been dumping sink on you. Have you flown it on other days? Unless we can see photos of the glider or get more information from you, I don't know what else could be the problem.
