Thanks to everyone who responded. As suspected I got a full range of
ideas - Add more off-set, remove all off-set, Throw at a steeper angle,
throw at a lower angle, Etc. the most common responses were:
1) To add a sub fin
2) Relax/straighten my arm during the throw
3) Add a wing peg
4) Release earlier in the spin
I will try to get out and try the 4 items above tonight (weather
permitting). I'll post results.
Thanks Again!
Any other Montana (Western MT - Missoula area) pilots out there?

Subject: DHLG Launching problems
I have a Poly V-Tail HLG of my own design. It was designed for the javelin
launch. It launches (javelin) and flies fine. Recently I have tried a few
experimental side-arm type launches "at low power". By low power I simply
mean that I do not rotate fast or try to generate true launch speeds (I
don't think the plane will take it). I am trying these test launches to get
a feel for the new launching technique before I build (or buy) a DHLG ship.
My problem is that on about 1 of every 5 launches the plane rolls over on
launch. No amount of pre-set rudder seems to correct the problem or reduce
its frequency. Living in Montana has some advantages - being near people
who fly sailplanes is not one of them! Any ideas? Suggestions?
