TruSpeed Controller Spec Differences

BAracer · 14th-Oct-22, 06:46 PM

I was casting my eye over the range of Truspeed analogue controllers the other day, and it got me wondering about something...I can see that the top of the range MT II and the PWM II controllers have all the bells and whistles a race driver could ever need, but it was the other two lower spec controllers that puzzled me.

The BP II Transistor controller and the MT I Mosfet/Transistor controller have the same two external sensitivity/brake adjusters, so what difference does the internal electronic architecture make in terms of user perception/car control?

Did you compare the two specs and customer reviews?

Yep, that's why I'm here.

Maybe it's more of an observation than a question, but I was intrigued by the hybrid spec of the MT I, i.e...

BP II - transistor drive, transistor braking
MT I - PWM drive, transistor braking
MT II - PWM drive, PWM braking

Good morning gents.
Thanks to Brian Rogers for alerting me to the forum topic. Thumbup

The MT I and BP II have similar characteristics but are sufficiently different to have ended up being popular for different reasons.
The website has a pretty detailed explanation of the features including current handling capacity and the basic difference between DC voltage and PWM for speed control.
Rather than copy and paste all that onto here, I'll give you links to the pages on the website.
MT I
BP II

Thanks for the response Steve.

If I could ask just one nerdy question as a non-electronic geek, the answer to which I don't think I can find...

From a user's view point, what is the difference between transistor braking and PWM braking?

Hi Steve,
I'm the happy owner of a MT I for about 1 year now Thumbup

In 2 weeks I'll run the "24 Heures de Cognin" in France and I was afraid to read that this club doesn't allow your MT II Controller due to "the braking technology that gives an advantage" to the driver
Do you agree ?

Have to say that I really hope that I'll be allowed to use my MT1 for this race Sweating

...

Regards
Fred

I'm so glad you posted this.
I brought a BPII a while ago and I have not been able to tune this thing in for the life of me.
After reading this post and then seeing that Steve has posted information about it which I've never seen, I have found the little Blue sensor adjustment screw.
Now I can use this god dam controller.

I have never written a review on this because I'm new to this hobby and everyone who has brought one of these raves about it, so I just thought it was me.
My only critisium of the product would be that the tuning information should come with a printed sheet when you buy the controller, it is an important part of learning how to use such an expensive piece of after market kit.

I was so close to selling this, I have already told someone they have first refusul if I can't crack it.

Thanks BaRacer for posting this thread, you have saved me from getting rid of mine. Thumbup

I've got a Scalextric Digital one, but I'm building up to getting a nice analogue one.

...and it has happened!

Have gone for an MT1 for my Raid/Rally cars.

I just wanted a controller with sensitivity and brake adjustments, so it wasn't a difficult decision.

Chose banana plugs so I can swap between the plug I need for the FDD event in France (in the photo) and the standard UK three pin plug for more local events!
