RE: hummingbird dd tail motor too hot.. Y????
3 Cell Lipo battery? If it is then its not rated for those small motors. @ 11.1V you will surley burn out your tail motor. I use a 7.4 V Lipo @ 1320MAH for my dragon fly its perfect I get 16 to 18 minutes of flight time. Rember that peak voltage for a 7.4V lipo is 8.2V and its considerd discharged @ 7V you can damamge it if you go below 3 V per cell. And a 8.4V Nimh is peaked at 9.8 to 10.2 will be discharged @ 7.4V. You are also asking a lot of your ESC at that voltage.
