I have had a number of runs on 8s so I feel confident that it is coming back to shore. Recently got my Dinogy 5s and 2s packs from Mark. So now we can go for it and I took her out today for a run. Kept everything the same as before; M447's, stingers straight level, batteries(10s2p 3300mah) in same predetermined position, 8 degrees timing, and thrust bearings in.
Don't remember if it was here or on KBB but there was a thrust bearing discussion, pros-cons. I am here to tell you that at higher RPM and longer runs they are not going to be desired. I heard a strange whine toward the end of the run(heard it on other runs as well), and when I opened the hatch a puff of smoke billowed out. Upon inspection I noticed a burnt grease smell and then noticed the thrust balls with a blue'ish tinge. I assume they went dry and heated up. At any rate they gotta go. BTW, not bad runtime eh guys? actually did a few more passes yet and the batteries were at 3.75volts and put 1900mah back into them on store charge.
