Hello Ivan,

The RC mart is the one we use, comes with the connectors on the wires on both the speed controller and motor. The ebay system I can not be 100% certain is the same. The Ezi-run can not be updated with new software, which is one of the best parts regarding the system.

The 25A/35A do not seem to make any difference on the track, although everyone will say get the bigger system. We have run both systems together and there is no difference to performance on the track in mini. The Hobbywing system is rebadged as a Venom system and as Greg said Yeah Racing. On our motors we have etching that says 13T at the end of the can.

I don't believe the different C rating makes any differnce, however a new Lipo is normally always faster than a old pack. I am using the IP4200 40 C Lipo's in my mini with the BL system and guys with older M chassis 4000 20 C batteries are just as fast.

Lipo's like Nimh's do get get old and tired, just not as quickly. I was always of the opinion that more voltage, hence current, that you can supply to a silver can the faster it might go. Previous experince with Lipo's and brushed motors is higher voltage equals more speed.

BTW

Just my opinion and experience with the Lipo's.

Amendment.

Do not go near this system that is listed on ebay. It is a copy of the original HW system. There is no brand name, no connections on the motor, blue wires for all three phases on the speed control, the program card is not correct.


Regards,

Calvin.
