the aqua star was a POS it was designed like garbage and i never even flew it cuz i was afraid id lose the engine as the flimsy pylon fell into the lake. the mustang was good, but like all herr kits the instuctions were NOT for the first time modler. they have no explanation of terms (this was my 10th plane so i didnt use them either i built off plans) but for the pourpose of this thread i advise against herr kits. (only 2 ive built) was going to give em another try and do that pitts later though the mustang was the thing that made me believe all their kits werent crap.
