I brought the Losi Xcelorin Combo a few weeks ago - i chose the 13.5T sensored version.
I'm pleased with the kit so far, but when i run the unit the motor sounds really really harsh and nasty - significantly louder than my brushed motor even.
I returned the motor to the retailer, who sent it to the manufacturer for testing. The report says that the engineer agreed that it was very noisy and replacing the bearings did not fix this. The rotor is not rubbing inside and floats freely between the bearings. As the motor isn't losing any performance, a replacement will not be offered.
So i've got a combo kit with a motor that sounds dreadful. Question is, what do i do now? Put up with the noisy motor, run it a few more times and see if it improves, demand a refund? Can anyone offer any advice as to why the unit might be so loud please and if it is a concern?
I would like to point out that it doesnt just sound slightly off, it's not far off being as loud as loud as a nitro when going round the track.
