This mighty machine has been built by Doug Wilkinson. It weighs in at 1200 lb and is using a 4QD-200.

I’ve just got to share this clip of Scarletts Ferrari, it’s using one of our DNO-10s and looks absolutely stunning. I guess that’s what happens when your Dad restores cars for a living – not that I’m jealous – oh no!

Follow the links to see some of the other fantastic cars he’s made.

 

Steve W sent us this picture of his Robot Wars contestant Gyrobot. It’s using one of our Porter 10XXs to control what must surely be one of the most powerful rotating energy weapons we’ve seen so far. We’ve made some mods for him to allow the current limit to be adjusted, and he’s also trying out a prototype heatsink arrangement to cope with the rather unusual power profile.

Mr B sent us this picture of a highly classified Xmas panto prop built out of a commercial scissor table with one of our Porter 10s driving a hydraulic pump.

Oh not it’s not……

…and here they are…. the first results for our new range of cooling options for the 4QD-300.

The finned air cooled heatsink gives approx 50% increase in performance and this can be increased further if a fan is fitted.

It’s the water cooling that we like the most though, it turns the 4QD-300 into a real powerhouse. More detailed results at higher currents to follow once we have uprated our test rig!

We’re still working out the pricing for these but please get in touch if you are interested.

Here’s a picture of our embryonic test set up for the soon to be launched water cooled 4QD-300. On the left is our current air cooled load cell, ammeter, and data logger. Front right is the 4QD-300 fitted with the water cooled heatsink. Right rear is the control and pump for the water. We’ve left space for a second pump which will be needed when our water cooled load cell is ready. Can’t wait to run this lot and see what results we get.

Jeff Ivers sent us this picture of his tow truck that he uses to haul a gravity racer to the start line.

Fitted with one of our Pro-150s

Here’s a sneak peak at our uprated 4QD-300X. We’ve had a custom heatsink made which really improves it’s ability to handle high currents for extended times. During testing it melted our test rig and was still only warm to the touch! Full details will be announced once we’ve built a new test rig.

The heatsink itself will also be available as an aftermarket upgrade.

 

We’ve also got a water cooled version coming soon that will take things even further, and be particularly suitable for electric boats.

 

Here’s a picture of MR Speed Squared, a 2016 Robot Wars competitor. Using 2 of our DNO-10s and a DMR-203.

Patsy brought a couple of PDQ Powertrikes to us with broken control boxes. We fitted one with a Porter 5, and one with a DNO-05 to see if we could get reverse, however we discovered that the motor has a one way clutch that prevents reverse from driving. The standard twist grips were swapped for our Magura throttles, and we fitted one of our key switches to the DNO for security.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Footnote:

Two weeks later Patsy sent us this picture of the neat bag she made to tidy it all up

And the verdict:….

"The power box is working briliantly, so speedy that I tend to do wheelies
unless I am careful. The battery is lasting longer too........
Thanks again for doing a great job on the trike."
