Hi Airwave
I have also tested the VTD for the D09 and I like it, but with 13,5t blinky, I have problems with the belts skipping. I have adjusted the tension and tightened both rear and front belt, I even made a belt tensioner on the top plate, with 2 bearings. When I change back to the standard top deck, no skipping belts at all.
The problem lies between the motormount and the rear bulkheads, when You press there both belts changes tension.
Please let me know if You find a good solution.
