Bill told me something interesting about this remote control multimac clone. The exhausts are the same as the Airfix Starcruiser Interceptor but I can't find a photo to hand for comparison.
Maybe Bill will take up the story.
Just looking at those exhausts they also remind me of the Dinky Space 1999 Eagle Transporter. Maybe not. And whilst we're at it, is the Dinky Battle Cruiser the same ship as the Airfix Starcruiser?
