Now lets upgrade some more stuff on the Spartan

[JPriami]

Well I did a kick ass job with the new dual pickup rudder and cooling system upgrades. So let do a little more!

New Turnigy 180 marine ESC, Leopard 4082 1500Kv & Cooling jacket.

Fits in there all nice and snug dont you think?



After doing the new rudder and setup I was able to keep the stock traxxas 36mm 1600Kv motor and ESC cool. Well under 90*F. So I felt I should have no problems keeping the new motor and ESC cool as well.



Cant wait to test. Too bad the weather is taking a dump for the next few days.

Now we'll all see the first 50mph Spartan for sure!

Nice.Looks great.I run the same combo on 6s in my 33"mono.I was seeing low 50's.Good luck Justin.Hope your water isnt solid in TN.If it isnt,Im coming down so I can run my boats.

It will be interesting to see how the hull rides giving the side to side roll we have seen on this hull with the extra speed & torque that you should get with this set up esspecially if you put bigger props on. Lets hope the weather improves soon. Thanks Martin.

Yeah I'm worried about that myself. In my other runs I had that problem at higher speeds sometimes. But I noticed battery placement helped. Also it didn't do it all the time. Seemed a little induced after hitting wakes. Still sucks tho. I'm going to try strut angles, props, trim tabs and battery placement. If I can't get it dialed in for good handling over 50. I think I'll just put the stock stuff back in it and sell it. Then use the stuff I bought towards another cat. Those genisis cats might be fun

Come on down Larry your welcome too. You can crash on the couch in the basement. Down there where I tinker on stuff. Bring a mini revo if you have one. I have a ramp down there too lol.

I've got some really nice lakes for running here. About 20 or so miles away.

I think the hull could benefit with either wider trim tabs are an extra set to get them closer to the strut because when the boat is at high speed up on the v theres no tab in the water. The tabs on the boat also look a bit on the short side as well. Thanks Martin.

So i hit 50.3 yesterday testing it. but I had to use an m445. i didnt have much luck with the prather 220. but my gps was acting up so I dont think the speed readings i got from the 220 were accurate.



The boat was still wanting to chine on WOT passes. I guess I will try adjusting the strut a little and maybe give the tabs a few turns down.

I wanted to ask do you guys think the stock traxxas servo of 80oz is enough for the rudder? I was wondering if the rudder could wiggle and cause the boat to act like its chine walking at wot.

[martin]

If you look at most deep v boats around they use much wider tabs that go much closer down to the strut, When thats up on the v theirs no tab in the water. Thats also not a very powerful servo for a boat that size doing 50+ mph. Are the temps much lower now than with original motor & esc

[Make-a-Wake]

Great, so the m445 worked out! The prather is just too much prop.

[JPriami]

Today's new speed. 55.4mph

Do NOT put tabs closer to the keel. It will create even more lift in the transom in the straits and induce more chine walk.

[martin]

The reason i said tabs further down towards the keel is i have a 15" mono deep v that runs 45mph & was getting chine walk to the point it would put the boat in. To the point i was practicaly destroying the boat each time it went in hiting the bottom of the lake. The boat did not have tabs at all, So i added a set down towards the strut & it has stabalised the boats chine walk but still has its speed. If the waters a bit rippley it will still go in now & again but not to often but on flatish water its stable where as before it would go in even on flat water where the chine walking completally upset the trim of how the hull ran. But this is on a 15" hull though. Thanks Martin.

Here is the video



There was only about one good pass. I think that's where it hit the best speed.
