Bought a pair for a RC car, boat, plane etc to record and show to kids. I ended up using them on some hot wheels and just used rubber bands to hold them over thinner profile cars. Kids love the engineering aspect of building a roller coaster using Hot Wheels tracks and then watching it on the TV screen. The camera doesn't get warm when using 25mW and the e-flite 3.7 batteries work well and last around 25 minutes of excellent action. Records video easily and very clearly in TV Converter and Portable FPV Recorder/Screen.
