To all of you with Firebat fever. I just finish building one and I find few faults. First I reinforced the ailerons on top with fine fiberglass because I find them very flexible. I’m going to try to fly it with 8 cells 600MA and a speed 400-6volt motor instead of the original 7.2V, I checked the prop speed with a tach and I find that the 6V turn faster at 12000 rpm. Now comes the best part: the CG. Here, I bet that everybody makes a mistake. Did you gays check it with a CG checker? I guess not, because I could not get the CG where suppose be. So, instead of adding weigh to the front, I split the battery pack: 6 cells right after the servo for the ailerons and the other 2 in the front of the nose. Now here I had to dig out some foam until the 2 batteries fit. Later I may send some pictures of what I did. For now I wait for some calm days to fly it. I also I have a different set up for using a 400BB and that require a different approch. See you later.
