RE: Walkera #4 Fixed Pitch Helicopter Forum
your motor gets too hot?...well my motor doesnt even get warm after hovering for 7 minuts! heres what you do...take rotor blades off ,lay flat on wood ,cover with sheet of paper .get wiffs iron .set on high and press blades as flat as they will go! hold on for 30 to 40 seconds. about half the pitch comes out. now throw that nmh battery as far as you can! and get a 640 mah kokam 7.4v poly pack. you will need to build a small extension on the front to move the battery out to get your cg right because it weighs 3 times less than the original!!! my heli jumps in the air at quarter throtle and flys for more than 10 minutes. I also have mods for the head that makes it fly so stable ,I can hover over a 5 gallon pail and land on it! Iv also solved the burnt out tail motor problem. let me know if you guys are interested...happy flying !
