Well my Truspeed MTII turned up last Thursday, and I have to say the build quality is first rate, as usual from Steve Hills, I also own one of his PWM II, and it's hard to believe that these are not mass produced by a large company.
The trigger is soooomth, almost contactless in its feel, and the whole thing is nice and light.
Now to the negatives, if you could call them that.
The controls on top are very smooth, meaning they have no feel, so, mid race I found it hard not to over adjust, no doubt I'll get used to them in time.
I got the high power one, so instead of the the resettable fuse, it came with a fast blow fuse, but it's inside the handle, so not a quick change if it blows.
The full power relay is in the handle, not down the other end of the cables, a bit strange, but as has been pointed out by those that know, it's not needed for the kind of cars/motors I'll be using it for.
The club i race with runs on 10 volts, and down there the response is a bit soft even though I had the sensitivity turned all the way up, at 12 volts it was fine, I found a fix for this by shortening the trigger throw, which is a $8 option, and well worth the extra, and can be fitted to most brand controllers.
One thing I really like on both the Truspeed controllers is the "traction control", it works without effecting the rest of the controller, unlike on the Difalco, which is that bad, I never used it much.
I'm yet to try out the Coast/HO mode, which is for cars with lots of brakes.
I used it at Friday night racing at Hallam, and got 3 wins from 3 starts, but I did the same last week with my Difalco, so I can't say one is better than the other.
