2012 March: The MT I is launched and selling well.
2012 March: the 2nd Batch of the MT I is produced and ready for sale. The MT II is designed and under test. It also features a function of the HO scale racing. The MT II is a dual polarity controller that automatically senses the track wiring.
2013 June: The MT II is fully tested and now available on the web site under MT I.
2016: The MT I and MT II are still selling well and have not needed any changes.
2017: Small changes in the MT II to make production slightly easier have been made, but these do not affect the operation of features.
The MT I has no changes.
2018: The only change proposed is a current limit for the MT II.
In some places around the world clubs are finding that the drive board is blowing more often than it should. This reduction in current delivery will help to save the Drive Mosfets from damage during short circuits on the track common with metal chassis racing and high current motors.
2019: The current limit is effective, but the biggest problem still lies with the countries that plug all 3 terminals in each time someone races. The chances of errors are so high that it is unavoidable that sometimes the racers blow their controllers. It is unfortunate that the slot car world has not come up with a standard system to use.
2020: This year research from 2019 will result in additional protection circuits to be tried out for the analogue controllers. Ideas to protect against wrong connection, short circuits and the generally very noisy slot racing electrical environment, are all being looked at.
Out of the 5000 or so TruSpeed controllers sold, only a very small percentage come back to me for repair or upgrade, but still, I want to get them better protected from the mistakes and mishaps that occur.
Once perfected these additional circuits will appear in the product for sale.
