Wrapping may NOT be the ultimate solution:
my Losi Xcelorin's Kevlar bonding/wrapping of the rotor got damaged by sand that got into the motor. That almost killed the rotor, I was able to fix it by putting super glue on it a couple of times. like that the kevlar didn't get loose any further.
The rotor of a mate's Losi xcelorin got seriously damaged like that: the magnets got loose, he didn't put super glue on it, then damage was too much.
They say that the newer rotors of the xcelorins (1/8) have now carbon-wrapping.
an other downside of a wrapping is:
it needs space, but the less space between the winds and rotor, the better. |
Y not just wrap the rotor with an ultra thin heatshrink over it?
Just kidding. Hey u have have a very good point there. I didn't realise that sand can damage kevlar wrappings. But how did sand get into the xcelorin motor in the first place? Aren't the endbells sealed?
