Bug Molsons velcro rockets DG Launchers

[Interceptor]

Hi I really love Molsons velcro rockets DG Launcher,but I noticed that when you change height to raise the DG launcher, so you could launch it from a pad such as the one on wideawake island, it starts out with the smoke,and flame effects,before you even activate the autopilot.has anybody ran into this problem before?,and if so is there a fix for it?Thanks
