@bigkid posted:Quick question (sort of in line with this discussion), how hard is it to upgrade to ps3 an engine that was conventional or something like ps1 (sound only)? My impression is that as a DIY project it is a lot more difficult than doing let's say ERR (not saying ERR is better than PS3 or cheaper, meant level of difficulty). Plus I assume PS3 is for DC motor units only ie wouldn't work on an AC engine?
Putting PS3 in a PS1 engine is the easiest as they were designed to do this and the instructions more or less assume thats what you plan to use the kit for. Putting PS3 in a non MTH engine will take more skills. Likely have make a new mount for the tether, create openings for switches, play with the tach strips or sound files to get the engine to run and sound right.
For non MTH engines ERR is probably easier for the novice. PS2/3 is only for DC motors.
