I am interested in getting a GM 10.5 motor for the Tc national here in the UK BUT ive heard rumours that they will lack in performance and not run very well when with a Nosram Esc and that they are really made for the GM esc's. Also i have heard that they are meant for Esc's that have variable timing like the GM or Stock spec esc's and dont perform aswell with an esc without this feature like the Nosram ISTC etc.
Is this true?
Could someone help me as i need a motor very soon and was interested in the GM , i dont know now though?
I wanna get one ordered but wanna be sure 1st
