axe 400 got hot
was hovering my axe 400 today out in my shop for a bit and all of a sudden it was losing power and got hot. I am wondering if it was becuase its hot outside and thats what happend to it or what? it seemed like it took a bit for it to get up to speed then it would take off but never did feel right, the battery was very hot and speedcontroler as well does anyone know if could be the temp outside or is something wrong with my heli?

RE: axe 400 got hot
The first thing that comes to mind is that there is excessive fiction loading up the motor. This could be between the motor pinion & main gear, or the tail belt is too tight, causing excessive draw on the motor & ESC, making them HOT.
Check your gear mesh between the motor pinion & main drive gear. You should be able to take a strip of paper (about .0035" thick), and feed it inbetween the main gear & pinion. It should come out the other side with neat folds, if it doesn't fit thru, or tears are on paper, the mesh is too tight readjust the motor pinion to gear. If the paper comes out with only slighly crimpled, the mesh is too loose, readjust.
A simple way to adjust gear mesh is to slip the paper inbetween the main gear & pinion, then push the motor up snug to the paper & tighten the bolts, then check the paper.
Next check the tail belt tension, it should be tight enough so the belt doesn't slip on the tail belt pulleys but not so tight that it loads up the tail belt drive, belt too tight. I normally press on the belt just behind the drive assembly it should deflect about 1/4" or so. If you hold the main gear so it doesn't move & turn the tail rotor you should feel the belt deflect but not slip on the tail pulley.
To adjust the tail belt tension move the tail gear housing forward just a bit, you may have to move the tail servo mount forward the same amount, otherwise your tail blade pitch & gyro will be out-of-whack.

RE: axe 400 got hot
Hey I called product support- which I have to say they are very helpful and the real deal when it comes to backing up there products I am very happy with them. Anyway they told me to lower throttle and increas pitch, also I cut a few new air slots in body had no problems since.
