I just picked up my Spartan from a guy on craigslist last week for $180!! It has the castle electronics and it is overall great condition. Seller also gave me the 7cell nimhs so I believe that he never ran it with lipos.
Anyways, I just received my new aluminum water jacket from OSE today. Before installing it I pulled the fittings off of it and noticed that the holes in the center screw were a little small so I opened them up to about 3mm. I was under the assumptiom that this would help the water flow better but tonite when I ran it I wasnt seeing any water comming out of the outlet.
Everything is sealed tight, there are no leaks at any of the connections and I can blow air thru the whole system so Im sure that nothing is clogged.
Only thing I can think is that im not getting the needed pressure now since the pickup in the rudder is so small. Maybe if I drill the rudder out or upgrade to the dual pickup rudder and use larger i.d. line ill see the water flowing again?? Not sure.
Also, by touch, the motor seems to be getting water for cooling because it feels about the same temp as with stock jacket maybe a little cooler, even after 15 mins on 6s
Thanks in advance.
