If it's anything like a brushless Gecko, then trim tabs won't help. If your boat is running faster now and hopping out of the water, it's probably because of the driveline or prop angle. I've noticed on the MiniV that the prop angle is negative, just like the Gecko. On my Gecko, I pulled the solid shaft out of the boat and chucked it. I then pulled out the stuffing tube which is what held the prop shaft. I re-installed the tube parallel to the keel of the boat and put in a flex shaft. Now I can go full speed without hopping. Trim tabs are just a band-aid to the real problem which is drive angle and possibly weight distribution.
