Not looking good on the ISLMM. There are three problems.
1) The SLMM interface is incompatible with wirecontrols
2) The SLMM interface only has one (terminal) waypoint.
3) The SLMM don't want to launch no warhead...
So basically, I can increase the range of the existing SLMM, but it doesn't appear I can add any new features.
Doh.
Cheers,
