The slowest gearing (17/36) is still to large to keep the motor alive on a stock motormount and stock chassis. With 15/36 you will lose speed but gain punch out of a corner and more important a longer life of your motor. Using a alu motormount and a heatsink the motor will stay cooler but still there is a chance to burn up the motor with the lowest stock gearing. When the motor is overheated a small dish to strength up the collector will go lose and block the motor, you may remove the dish when opening it. |

Post subject: | Similar problems with motors |
Drivers in my micro club are encountering problems with the XRAY micro motors (burning out, seizing up) using stock gearing too. And at least one person had an XMC-180 fry soon after starting to use it. On my car, I run the following: * XRAY or HPI micro stock motor * Novak SPY ESC * GP1100 5-cell pack * Alu motor mount * XRAY motor heatsink * 19/42 gearing (sometimes even 21/42 but acceleration suffers) * HPI high-performance carpet rubber tires (all around) * Profoform Mazda6 body I have not yet had a problem with my motors, and the car seems fairly quick and punchy. I get very good runtime. After a 10 minute run, the heatsink is warm to the touch but not overly hot. Also, the screws for the motor mount are also a bit warm, so I assume the motor mount is drawing heat away as well. I believe that the others that are having problems run the stock gearing (17/36) with no heatsink and stock composite motor mount. They say that their motor gets so hot that touching it would blister your skin. I think that the combination of metal heatsink components I use (motor heatsink and motor mount) is what is stopping me from having the same motor problems. Glenn Cauley Ottawa, Canada |

You should also try the Orion stock motors. Towerhobbies has them. I burned up a motor to 2 motors a week trying to race when I first started racing xrays. Even now the newbies are still burning up those xray 180 motors. Do yourselves a big favor, buy the HPI or the Orion Stock motors and get a heat sink or an engine heatsink mount. |

hey, The stock motors do get pretty hot, what we did here was amde a slot on teh chassis and so air will flow in, or anotehr way is to make a scoop on the side of the motor. You can also gear down. The temps Im usualy at on Ozite carpet is 102F [use a temp gun]after a 7 minute race. i run 17 and 36 spur. I take off all teh stock motor lables, because those only keep the motor warmer,[like a jacket] . those clicking sounds in teh motor, is loose wires, snapped off brushes, dues to motor over heating.. I hope thsi helped |

The powepack is indeed a waste of money but getting a mamba brushless is also spending a lot of money (and there are some cogging problems with it) Choosing the right ESC, batteries and servo is a good point to start with and as a motor the Graupner Speed-300/6v is the cheapest thing to get for lots of power and speed. |

Did not try it in a Xray yet.... My MRS4 setup: To give you an impression: http://aktionrc.com/video/sleepertrailerhires.wmv And there are more crazy people: Again, no Xray but does support a 540 and 6 sub-C cells ![]() Yes, you do need to fix another motormount but with a piece of aluminium and some tools it is easy to make. Fixing the batteries is yet another problem..... |
