So over the last few weeks I've put two new RX8 Gen 3's in my new Tekno's, one ET48.3 and one SCT410.3, plus a RX4 in my crawler. The ET has the Gen3 T8 2250kv truggy motor and the SCT has the T8 2650kv buggy motor. Crawler has the ROC 412hd 1800kv. My question is what actual difference should I notice by adjusting the frequency settings through hotwire? When I compare 2000 to 12000 the only thing I really notice on either vehicle is the motor makes much more noise on the 2000 setting. That's about all I notice. What does it actually do?
