after about 40 hrs of working on this thing, i finally got it the way i wanted it to be. went to the lake last night and ran it for about 3 hrs. everything worked flawlessly and only have about $600.00 invested in it including the 9.9. ive always shot off a troller rig and never realized how much easier it is to run this thing instead of the troller. it jumps right over rocks and stumps and keeps going. does anyone see anything they would change to make it better? im open to anything because this is the first one ive built.
