I've been getting 53-54mph consistantly with the SK180a and stock CC motor (1800KV). Temps have been in the low 100's. The biggest issue is for whatever reason, the stuffing tube has been spitting grease back into the hull. I suspect that the drive cable is taking a turn for the worse. I ordered one of Wohlts .078 drive wires and a speedmaster stinger/strut to solidify the driveline. Some of that heat could be coming from the driveline going bad. Anyone ever had grease come back into the hull rather than being augered out? I'm also going to get a RX battery pack today. Couldn't hurt to take it a little easier on the ESC.

You shouldnt be getting alot of grease in the hull. If the motor is turning the wrong direction, it will force grease inside. I doubt you are running the motor backwards. Is there teflon in the stuffing tube? What size is the stuffing tube?Comment

It's both the stock stuffing tube and liner. I've got an Octura liner coming. The only thing I can figure is that the motor wasn't perfectly aligned with the stuffing tube. I notice also that the liner had gotten longer by about 1/4". I'm guessing it was getting pinched at the opening somewhere.Comment

It probably would. We have run bigger props, in addition to Prather 225 and and Octura X642, we have also played around with some three blade props on both Spartans. But my daughter finds it more fun to run, than to retrieve and repair, so she is happy with a bit less speed, and decent reliability.That is a tiny prop for such a powerhouse motor, no wonder it is rock solid. Kinda like running in first gear all the time.
You will need to install a heater on the components to keep things from freezing up? 
I really think that it would be as reliable with a larger prop and upper 50,s easily attainable. I will not be shooting for top speed either, rather monitor temps all around and let the temps determine how fast it will go. Would like to keep things sub 120 all around.
I run the same setup, T180 and Leopard 4082 1600kv in my Fightercat / Genesis hull with an X642 and it is fast. So far the electrics are reliable on 6S but the problem is I can't keep the crappy 4mm 2 piece drive lines in it for more than a run or two.
I have some parts on order from OSE that I'm hoping will allow me to modify to run a standard one piece 3/16" shaft and .150 cable with better reliability.

I will be making a few changes and one will be the mediocre strut they have on the Spart. Bought a couple of these and for the price, they are a steal. Really well made and high quality stuff. http://www.hobbyking.com/hobbyking/s...r%5FDrive.html They take a standard 3/16" shaft so things get more standard. Only problem is the portion where the brass tube slips into it quite big but a small piece of teflon tube to act as a sleeve so it will take the standard 1/4" brass tube. I twisted my stock drive cable on maybe the 3rd run of my new Spart and ordered Jeff Wohlts replacement. Never had an issue for the entire summer. Obviously this is working for me so I will stick with his stuff. I have also considered the piano wire stuff and actually have an untried one lying in my tool box. I am a believer in teflon liners for added friction reduction when grease wears thin. I also grease at least after every 4+ battery drains.Last edited by Snowride; 02-29-2012, 09:20 PM.Comment

WOW. The Leopard showed up today and that thing looks like a beast. They threw me a curve though as the bullets were 6mm. Luckily they supplied the females. I'm waiting on the speedmaster stinger/strut, octura liner, and prop nut before I put it in the water. It's probably going to be a week before the wire drive shows up, but I have a Wohlt .150 on hand. I also swapped from a BEC to a RX battery. This should take a little load off of the ESC. If this works out, it could be a 60mph Spartan that doesn't blow up.Comment

Nice that Leopard has upgraded the size if the bullet connectors. Unless that is an upgrade requested by Steven on his special orders.
I was swapping mine out for larger Castle Creations connectors, which I think are probably about 6mm.

I have to give Steven some more props (no pun intended) on his outstanding customer service as well. I am an inpulsive buyer and sometimes end up making multiple purchases on a whim. Well, on my stinger/strut order and another miscellaneous order placed at different times, Steven proactively combined shipping and issued a refund for the overpayment. It wasn't expected but was very much appreciated. My LHS treats boaters (or at least me) like lepers. They've seen me for the last time as well as my money. If it weren't for this site, OSE, and others like Kintec Racing, I would have sold the boat already and moved on to another hobby.Comment

After the first batch of motors we switched. The 4mm bullets they use weaken easily with heat. All the 4082 motors now have the larger connectors and vented cans. A few 3674 & 4074 motors still have the 4mm connectors. I'd estimate at this point 98% of the motors that leave OSE now have the larger connectors. Especially the more popular windings.Steven Vaccaro

Ditto.
Steven ships fast and orders are always accurate.
The two LHS here are good folks, but RC boats take a back seat to planes and cars.
The vast majority of my rc purchasing is done on-line out of necessity and I appreciate that there are quality vendors that value customer service.
