Testimonials

Just a short note to say thank you very much for all your time and work yesterday it was very much appreciated.
I completed the wiring this morning with the help of your diagram and all works as it should.
Now to finish the body and get out on the track.

Firstly, we were able to complete approximately another lap further than the xx. And this then leads me onto the best factor we had from the xxx. The tail off seemed to be much, much, much slower. Before we would go strong, slow a little and then very slow for the last lap or so. The xxx allowed us to keep pushing at a far faster pace with only losing a few seconds per lap (over a 2.4 mile Goodwood lap) during the last few laps. This then allowed us to gear up and get the Kitcar to an average 26.5MPH over a race. Your controller did not heat up at all. The only cooling we had on it was a computer heatsink with thermal paste. We came first Kitcar by several laps, and 8th/11th overall out of 100 teams (43 Kitcars). It was so impressive that we are looking at gearing right up next season if tests continue to be successful.

Thanks to Steve for guiding me through the problems I was having with my Pro120. His patient assistance was of the highest order, and he even made a short video to help show me how to check the connections and voltages.

I showed the machine a multi-meter tonight, and made it look as if I knew what I was doing and it decided to start working again so we are up and running for the Summer.

Thanks Steve

Dear Steve,

Again many thanks for your great support. Our start into this year's season was a full success thanks to the great Pro150 controller and your great effort in supporting us.

I have attached a photo of your V100 German class 212 loco of today's running session. Unfortunately our fun was ended by a wintery rain and snow shower just after about two hours.

Have a great week!

Best regards,

Dear Steve,
A very big thank you for your help on the phone and at 4QD to find the
problem with the electrical drive of my battery powered vehicle. The
problem turned out to lie with my wiring and my power connections.
Thank you for your patience and persistence to fault find the problem.
You really engaged with my problem and my application. A very
efficient and professional service from 4QD to a very high standard.
Thank you.

Without rambling further, I want to say it has been a good experience working with you and thank you very much.

..... Secondly we came 2nd overall in the finals with your porter 10xx and were only 96 metres behind first place, as well as coming first at every lead up event previous to this…a massive improvement upon the future and so I thank you for this, finished joint 23rd overall which is amazing for a Kit Car….

Thank you for the meet and greet Wednesday 28th a complete eye opener, we can’t thank you enough for your help. We will meet again I’m sure of it, for the next project, we have in mind,
But first!! We’re hoping to get the Jeep up and running soon (photo’s to follow)
Thank you again you’ve given us hope again for completing the Jeep project.

We received the controller today and thank you again for the quick turn round service. Hopefully another 12+ years of good service by the controller.

By the way it seems you reputation is growing on Facebook, a recent post about controllers attracted multiple comments, including my own, about how good your service is.

Again, thanks so very much for your help. I think I'm back on my way.
