Team Orion Rush Break-in and help

[bizaare69]

Hey guys i just bought a team orion rush 17 turn x 2 i need to know how to properly break it in and if i need to solder capacitors and where i also want to know what gearing u guys would suggest i am putting this motor in my HPI Sprint RTR. i have the stock gearing still which im not sure but i think it is 27 pinion and 92 spur im not sure but what would u guys suggest? thnx for any help in advance

For serious racing the ideal way to break in brushes with modified motors - those with adjustable endbells (this takes a little knowledge of knowing where the timing markers are on the motor plus a little motor knowledge). For serieous use you want to breakin brushes at a low voltage (now higher than 5volts or a 4cell pack), loosen endbell screws and rotate endbell to the zero degree mark then breakin brushes after breakin rotate endbell back to the desire timing and use. If bashing or you have little knowledge in motor setup or reassembly just run motor for 15 seconds or until you notice motor pickup speed a bit or hookup to esc and use partial throttle on radio to seat brushes.
The pinion that usually comes with most kits is not ideal when using motors other than the kit motor so my suggestion is start obtaining an assortment of pinions 16-29 but start with the suggested gear ratio either it;s listed in your vehicles manual or included in the motor packaging. Then you have to experiment trying different pinions until you achieve the desired results. You should obtain good acceleration, speed decent runtime while the motor stays relatively warm to slightly hot with no severe wear to brushes or other parts of motor. Using a pinion that's too big or too small generate the same problem severe heat buildup and wear.

For the Rush, when messing with the timing, get yourself a timing gauge and snip off the little tab that prevents timing from going too far in advance: Not only does it not let you advance the timing much at all, it actually lets you have a lot of timing in the opposite direction, which is bad for performance.

I have a Racetech gauge that works very well. Just remove the endbell and snip off the tab with some side-cutters, or slice it off with a knife.

You will need to add capacitors. I am pretty sure the HPI ESC is a high-frequency, so you'll need 3 'high frequency' capacitors (Pretty much the only ones sold now: You're LHS will know what you need). Solder one from the positive motor lead tab to the tab on the timing screw. Do the same for the negative lead tab. Then take a 3rd cap and solder it from the positive lead tab to the legative lead tab.

If your Rush is like mine, it won't have a tab on the timing screw: I pried the eyelets off the brushes in mine to solder them on, so I bent one at a right angle and used it for a capacitor tab. Works fine.
