Traxxas Spartan

[oscarel]

Yeah, those Castle motors are monsters. The 1717 that I have on an outboard was initially air cooled and it never got hot even pulling spikes over 180A.

actually you can have very fast setups without motor cooling with the proper motor to do the job

When I put a CC1520 in mine I wont have the room I don't think to run a cooler, so I will see how hot that motor gets

You are probably right that some motors run very cool & you might get away with no cooling ok, But a lot of motors especialy some of slightly cheaper ones run very hot indeed. Not sure if this is down to their design, build quality or inferior materials or all 3. I watched a guy on sunday run his brand new first time on the water DF 25" knock off boat with a fsd 380 motor had the motor seize solid on its 3rd short run. Total run time around 3 minuites in total for all 3 runs, Motor was extremally hot with water cooling working ok & on fairly small prop doing around 35mph. Im tempted by the spartan but an concerned about some of the side to side roll ive seen but that may just be incorrect set up & trim. It will be interesting to see how the hull runs going well past 50mph so i think ill wait & get more feed back as its very early days but first impressions seem very good & their close to delivering on their 50mph out the box which we probably all had some douts to whether it could delivered but looks like it will. So fair dues to Traxxas. Thanks Martin.

Water cooling a RTR boat should only need the single pickup. Most boats really only need one. I ran a single rudder pickup in a HOT setup twin cat. Worked just fine. You can simply just add a T or Y connector to split the incoming water.

Anyone have any vid of a well set up Spartan making some decent passes??? The few i've seen are either straight at you or figure 8's or the batts we're "too far forward" etc......................real vid, not promo................?

it wastnt a water cooling problem as he had lots of water coming through but a motor problem, Not sure if it was seized bearings or a failure inside the motor but their was a metalic bang & the boat stopped instantly. Thanks Martin

pulling 180amps and not getting hot, is impresive!

any of you guys have a water issue ? no water coming through my buddy for cooling , he is going to put bigger hose on it...

I'm still referring to this..

I agree 100% that 1 pick up is enough for most boat especialy rtr boats for cooling, The point i was making about having 2 is if you do get a blockage in one & dont notice it youv halfed the odds on potentialy damaging both the esc & motor as one will still have water going to it, Just a bit of extra insurance on expensive parts & no down sides really on 2 pick ups. Thanks Martin.

take a look at the rudder
make sure the opening is good
I use a point file on my SV rudders to open up the inlet, and I get possibly 50% more volume going through the system

My SV motors with big props like a CF48, never get above 125*

I also open up the hole with a round needle file & also make sure the groove goes right to the leading edge of the blade for increaced flow, Some rudders the groove stops short of the leading edge. Thanks Martin.

Thanks for the vid

[Rumdog]

looks good!

One of the better video's so far, looks like it handles really nice on 4s and is pretty quick. Was that still about 33 mph like the data showed?
