So, after not being able to run my car for quite some time for multiple reasons, I finally got out to test the HV458s! Car; Tekno NB48 2.0, rx battery; LIHV 2.6, radio; Sanwa M17. HV 458 on steering and throttle. First couple of laps were to get my brain, eye, hand, coordination back together. I was turning in to pipes all over the place and the car was nervous - a combination of me and the servos? Nope; me and the radio. The last time I ran I had my previous brand servos in the car and the radio was set nanospeed fast. I slowed the radio back down again and was back on track with the car feeling very good. The steering felt linear and I had to take some brake out - these things are really no joke when it comes to power and speed. NO buzzing or humming whatsoever as I spent the time after putting them in to get the EPAs set up to where they needed to be. Tomorrow will be race test and I will post up after. I'm impressed so far.
