Hey ecotech well after hearing so many sweet things about the vortechs i am going to be picking up a used mp40 from a guy whos getting out of the hobby.... long story short he says it doesnt have a controller or anything so im a bit worried.... is ther ea way to upgrade to a controller so i can have like reef crest lagoon and the wave mode?? Or if not do you guys offer like a trade in of an mp40 and then id pay the difference to like an mp20 or mp40w??? Thanx a bunch
