wich ESC/motor

[HootMaRoot]

i am looking into converting my TTR ER-1[1/8 scale TC] from nitro> BL

but i amnt sure on what system to get i had been looking at the speedpassion silverarrow ESC/3.5motor but that was till i noticed it was sensored setup, and have noticed the sensored motors are a bit more pricey compared to unsensored motors

i have had a look at geting the castle MMM but am now having trouble on finding unsensored motors of about 4500kv > 6000kv

if anyone can advise me on wich ESC/motor to use as i am new to the electric side of things and since BL seems to be a lot more reliable and faster than nitro
