Well had a pretty good camping weekend .Brought Bismarck along and a couple of tanks. The lake was excellent and I was able to run the model this time for a long time to run the batteries down. Checked out range by cruising out to the ends of the lake and intercept local boaters in the area. Tweaked the B turret cannons to get them to fire harder and in unison. Flooded the hull to test the pump and I played around with the ballast by switching around the receivor and the Nimd Battery pack. I started a 20 oz bottle then after using that up I switched to a 16 oz bottle from the Mo. I got to say I liked the fit of the 16 oz better than the 20z. Fired off hundreds of bbs. The local RV's and campers in the area enjoyed seeing the model . I will post the pics later. Curt
