Not to scare anyone away from bl I have run them all. Novak is the fastest in my book but I have had the most problems with the GTB then any other. The 160 thermal shutdown I thnk is way too low a temp. STLNLST....what proile do you run your Novak on? Reaon Iasked is I ran the 3.5 on a Xray EU geared 116/18 and thermaled left and right. I thought it was the drag brake I had in it so I took it out completely and still thermalled. Any advise here?
