Hi there! i thinks this Will be the last mod , including improving wiring cover. i Will post some photos painted. Today had to repair one coil too but it's working good again!

Hi There,
Very nice build, looks very good! 🙂 And it seems to run very good looking on your Youtube videos.
I'm planning to build my own,and I you dont mind I would like to ask you some questions regarding the retarder and shafts...
What type of brake are you using? I can see on the pictures that they both are Telma, but which model? (Max rpm, torque etc). I'm planning to use two either two Frenelsa or Klam, depending on the best offer.
During my design I'm struggling a bit with the dimensions of the shafts.. I'm not sure if I should use 40mm or 60mm shafts, any advices? Which dimension are you using?And Again, very nice build 🙂
Best Regards

Thank you! I made it 55mm shafts. but you can use 50mm or 60mm too. Dimensions will have to do with the complete build you do and what size of brakes and model for coupling have.
Hi Walter, your hub build looks awsome! What bearings/model nr did you choose for your hub build?
Hi! bearings are UCP211.

Hi there! Yourdyno is working, need a bit PID adjustment yet, calculate MOI, Ive worked with another DAQ before and Yourdyno software looks very good, simple, needs a bit of work , maybe some more options , get better dyno sheet, etc. anyway everybody can work good with Yourdyno. Pretty sure Jostein will improve even more everything!
Also a very very important thing when you get a DAQ, is support, Jostein is doing a great job! i will put some videos soon! 😀
Still a bit problem with shafts centering but today tested it without Yourdyno yet, i will connect everything tomorrow and do first test with eddy brakes working.
