do you think it would be all right to just use electrical tape, because i dont have any heatshrink. also, for the antenna that you said you can get so good range on, did you make that one internal, or external? sorry for all the questions, i just think that an internal antenna would be awesome. also, is there any risk with an internal antenna with it like touching a heatsink or anything, or is that the battery wires that will short it out. i cant remember this stuff, and im not very learned with electronics.
