Right there with you bro! Sold both of my NIB units and 2050kv T8s when I just couldn't keep them operating reliably.

I am running a Tekno converted D8...very heavy car...a shade over 9lbs. IMO RX8s are just WAY too touchy and fragile when trying to push around a 9lb. car. Could never get it to run cool...regardless of gearing, battery or motor. Motor always ran hot too. I tried everything over a 4 month period. Eventually they both (main unit and back up unit) literally burst into flames in the car on a track day. What a nightmare. I consider this my dark time of experimentation for a lost cause!

Reinstalled my mamba system and castle motor...works like a dream now.

I know a lot of guys who run Tekin without a single issue. But not me...what are you gonna do? LOL
