If the KR Governor with switch is connected to the speed controller (standard 3 wire hookup) and the speed controller is connected to the motor (standard 3 wire hookup) how does the KR get feed back to controll motor RPM? 

 

as Dennis said - and it works EXTREMELY well - I had one turn up today after seeing one in action last week -  the new software added is pretty cool too - can make a 4-2-4 engine run if you like it that way.  VERY cool

OK!  The KR is a 4 wire hookup.  That makes sense to this old retired engineer. The standard 3 wire Futaba style plug/cable provides power in (5V dc), ground, and control signal to the speed controller.  Then there is a 4th wire between one of the three motor leads and the KR.  This lead acts as an tachometer.  All very cool.  This allows the use of any speed controller (like in cheep).  Thanks guys for the info.  This info stopped the old headache (at my age it hurts to think).            

John, I agree with Dean......just keep thinking! If you want to have a look at the system on my website then it's here: http://www.keithrenecle.co.za/Electric%20CL.htm

I did not want to start bragging about the latest firmware yet. I know that Andy has been itching to post something because he has been helping to test it out. I just don't like to jump the gun until I have the finer details sorted out. I can say however that it is a differential governor gain that kicks in when you climb or hit a hard corner, and this simple thing makes such a good difference that you can lower the lap times and still have nice power through the pattern. Everyone that has tried this so far has been very impressed.

The other big reason for not saying anything is that the guys that populate my pc boards with the smd parts have screwed up big time and I don't have stock. I placed the order on December the 1st. It's no good to start blowing your trumpet if you can't supply! I have been told that I will get stock by this week, but I'm not holding my breath! Please don't shoot Eric at RSM in the meantime, because it's not his fault. Once I have caught up, I will not run out again because I have a new design that has less production hassles, and I have ordered larger quantities. My humble apologies to those that have been waiting for their timers. I will post something about all of this shortly.

Nice one Igor! I don't think that I've ever thought "in the box" so far in my life, so for now it will remain that way.

Will it be possible / feasable to upgrade the older timers to this newer firmware ?

Hi Allan,

Andy has the necessary programmer and experience to do this in the USA, so talk nicely to him and it can be done. In fact all the testing has been done on the first version. I'm extremely grateful to Andy for his continue help and feedback with this project. Thanks Andy!

Like Keith said ... Nice one, Igor!
