My car's has always done that so i THINK i may be fine!!!

Motors are meant to do that, they have something to do with electricity thingo maboby
and it should be fine, but if its seriously full on sparking, then check with it at your lhs

cool, thanks guys in such an idiot

all cars do it. ever look inside the vents on a drill when you use it? it sparks to. all electric motors like these spark, its totally normal. Now if there are sparks like SHOOTING out through the vents and such, THEN you have a problem. Otherwise, its fine.

i have an indor heli and that practially lights up!

Wow, Never thought so many people can be wrong on one topic. Go to a hobby shop, have them Tru the motor and instal new brushes, this sparking you see is calling "arcing", when a motor arcs, it causes excess heat, excess heat causes a loss in performance. get it cut, get new brushes and have them break in the brushes. When the arcing comes back, do it again.

my heli is brnd new only used it once. should it do that on the first go?

so how come practically every electric motor I've seen does it? Not saying your wrong, just wondering.

maby every electirc motor is broken.

lol, never trust electrics....

lmao

brand new motors never went through a break in process, without that break in process, the brushes will always arc until you replace the brishes and properly brake it in.
