i suggest you should USE brushless motor + lipo 7.4~11.1v 2-3 cells la~
mini inf is too heavy, needs to use a smaller pinion, 5~6.8Kv should be ok fast enough, 8kv+ needs to mod alot for smooth safety run!
very depends on how much u r willing to pay for upgrades? only upgraded a fast brushed motor, i'm sure it is gonna be died sooo quick. never just upgrade a fast motor without upgrade other important parts. A short life time repleacements may cost u more than some modding.
if u r playing on the cheap way, try these china made lipo, and brushless ESC + motor, totally value is cheaper than a Trinity motor, and you should think it is worth with good C/P. |
