You could try bending the antenna tube so that the tube stays under the body, but that will adversely affect your range and being that close to the motor wires I would be worried about picking up EM interference. Airtronics has a new radio combo out for $99 and it's 2.4G, still pricey for a radio but you'll wish you had spent it when your truck takes off at full throttle and hits something/someone. 2.4G antennas are only a few inches long and unless they are near something that may snag the antenna I typically just let them hang loose.
