Hello I also want to know have any of you played with a Megatec sub,,,, the white one with the lights in the front. Looks like a mini Mako sub. I got one for 30 bucks on ebay,, just to experiment with it I got another Walmart Sub on Ebay. the only full size RC sub will be my scratchbuilt PVC freestyle scale model. I noticed in the pictures of the make with it's nose cone off.. is that a fiberglass circuit board?? looks well made. Thanks TOm.
