RE: Ebay find!!!
With regards to the Titan 550 12T motors, I think there are just a lot of variables.
Mine has been lasting quite well, but I guess I'm gentle on it:
- I've never run it with the fast 23T pinion
- I'm never at full throttle for more than a few seconds at a time
- I keep the bushings clean and oiled
- I've never run it with more than a 6 cell NiMH pack. (I know John runs big 2S LiPos all the time...)
- When I'm doing a lot of running in grass, especially at slower speeds, I keep an eye on the case temp, and it never gets too hot.
Running 7 cell or 2S, slamming to full throttle from a full stop and things like that will cook them a bit faster.
