no offense ...niether do i ...but i have never seen ANY nitro motor that runs good temping at 160 degrees after a main .....but hey the extech .24 may be the only one that does ...one things for sure ...i will find out when mine comes back from powerhouse rc performance .....i would imagine the motor will probably temp at 180-220 range on a good race tune ...after a long main ...i know for a fact that the grp motors dont run well if temp goes any higher than 210 .....i hope mine could win a race temping at 160 ...i will run this motor for 2 years without touching it if it does .....
