Hello. i dril new holes to motor on rustler gearbox.
but you can take of front of motor and drill and tap new stock 25mm apart screw holes. that i have done to some of my motors.
yes i think the 2300kv L is more powerfull than castle/neu. but castle/neu 2200 runs cool on 8-9cells lipo and have a huuuge margin for sweetspot so its really a much better motor. but for speedruns i wil always put my money on the kb45 2300kv.i have actually downgraded my rustler to the castle neu because it kept wheeling at 140kmt because i run out of space and had to push harder on the trottle to max it out. with the neu its a bit lighter and its easyer to control on trottle.
here is some of my cars. remember im in to speed and not bling bling. dont care how it looks it just have to be fast and do the job :

i have added much more downforce to the speedrun rustler but havent gotten pictures yet
this video is with a smal motor that i also put in alot of lipos : and it gets to free rev at a time because it loses the pinion. it spins at 90.000rpm
its the turnigy 2600kv 36/56. when i get more time to get my rustler dialed in with the castle neu and then with the kb45 2300kv i will do a record attemt
