Interview with Jörn Neumann

image1-2

HMX: Congratulations for your second position in 4wd and top 10 position in 2wd at the EFRA European Championship held in France this summer! You used our HMX10 Modified speed controllers in both of your cars. Was the ESC important for your success?
Jörn: Yes, at this track it was very important to have really smooth electrics to get the most grip as the track had not much grip.

HMX: What are the most important differences for you as a driver between the HMX speedos and old fashioned speed controllers
Jörn: I think the biggest difference are the fine adjustments which you can make with the HMX speedos. On old style speedos not every parameter allowed small adjustments. With the HMX that changed and everybody can tune it how they like it.

HMX: HMX speed controllers can be setup by the Android app using an included cable, the iOS using the wireless dongle and the PC software. Which device are you using and why?
Jörn: So far I use the PC software, because I don’t have a iOS BLE dongle yet 😉

HMX: Will “normal” drivers feel any difference using the HMX controller – will they make faster lap times using it?
Jörn: I am sure everybody will feel the difference when using the HMX speedo. It is very smooth, especially at braking. It’s very much possible that they will achieve faster laptimes if correctly used.

HMX: What is for you the most important feature of the HMX 10 speed controller?
Jörn: To pick one feature is difficult as the HMX has so many good features, but I would go with the brake frequency setting as it can make a big difference on the track.

HMX® Technology is very proud to announce that David Ronnefalk won the 4wd European Championship title in Reims/France today, just a few days after winning the 2wd title! This is the sixth Euros title for the Swedish ace! With Jörn Neumann on second position this makes a dream result for HMX – the new generation speed controllers!

After the US National title and two Worlds titles of Ryan Maifield in 2017, this is the next amazing success for the 32 bit processor controlled HMX® devices!

Can THIS be a coincidence? Since its release in 2017 the HMX speed controllers have become double World and double European Champions!

The race in Reims today was a show of dominance from David Ronnefalk. After taking TQ position, the newly crowned 2wd European Champion won a main number one and two with an advance of 2 seconds in the first and 4 seconds in the second final. Compared to the 2wd title this looked like a walk!

Many congratulations go to David Ronnefalk and his mechanic and mentor Adrien Bertin for this incredible result, and to German super star Jörn Neumann for his fantastic second place!

The final day of the 2018 EFRA 1/10th Electric Buggy European Championship was held in Reims/France yesterday. We are proud to announce that David Ronnefalk took home the victory in the 2wd class in front of Lee Martin and Joanna Haatanen using HMX speed controllers!

Starting from 4th place on the grid, David placed himself on third position in the first a main on the slippery and demanding race track. Only pole setter Michal Orlowski and Joanna Haatanen were in front of the Swedish ace.

In a main number two, Haatanen and Orlowski both made an early mistake while Ronnefalk and Martin were battling for victory in an extremely hot fight. It was David who won the battle with a lead of 0.114 seconds.

Now all came down to the third final to decide who was the European Champion 2018! Again Haatanen and Orlowski were in early troubles which allowed Lee and David to take the lead. While being on second position David knew it was enough to win his next European Championship title. With 3 tenths of a second Martin won the race in front of David and Neil Cragg.

David Ronnefalk crowned himself European Champion 2018 using the HMX 10 Modified speed controller. Congratulations!

HMX® Firmware and App Updates

170728_firmware_pc_update

We have released new firmwares 1.04 and 2.04 for modified and blinky. The main changes are:

  • Low end power response improved
  • Possibility to have stronger brakes by lowering brake frequency
  • Timing increase now has more effect on performance (need less timing than previous firmware)
  • Punch setting range extended
  • Max torque setting function improved
  • Added a brake frequency setting to change brake feeling/power (lower = stronger)
  • Modified firmware now has default working timing settings (RPM/Turbo) with 10deg timing (you don’t need to start from scratch anymore)
  • Blinky firmware 2.04 is EFRA approved

The PC app and Android app have been updated to make them compatible with these changes. You need to update both the apps and the firmwares, the Apps are only fully compatible with the latest firmwares. If you had existing setups inside the Android app we recommend that you rework these setups again, because they might not be fully compatible with the new settings and/or they might not provide satisfactory performance as we have made changes to the power curve internal settings to improve overall performance and feeling.


NOTE: Modified and Blinky firmwares do not have the same internal settings, you need to use the Blinky firmware for best performance in Blinky class. The Blinky firmware is the only homologated firmware for Blinky races. With the Blinky firmware all the timing functions are always disabled, it is impossible to activate/use timing with it. The Apps and firmwares are always separate files, the Apps do not contain the firmwares, you need to download them through the Android app or manually from our hmxtechnology.com for the PC app (which you also have to download from the website).


Known issues in the Android app being worked on :

  • After flashing a firmware you need to close and restart the app to be able to modify the settings
  • Setups don’t show in the app unless you close and restart the app
  • Voltage cut-off reverts to 2.8V/cell when a setup is used to change the settings vs making the settings manually

New ESC Firmware and PC Software Update available

firmware_pc_update

We are pleased to inform you that new ESC firmwares and a new version of the PC software are available to download. The main difference is that you can now set the timing1start down to 1’000rpm instead of 10’000rpm. This will result in more performance for boosted stock and slower mod motors. With the new firmware and the new PC software  you can also reset the settings to factory defaults. You must update the ESC and the PC software in order to use the new features.
