    New to FE boats, Bought a Spartan.

    Hi! Just wanted to introduce myself and talk a little bit about my plans for this boat. Unlike many people that purchased this boat expecting it to be perfect, I knew it was flawed / imperfect and bought it knowing it would be a challenge, but thats part of the fun, right? Oh yeah, that and I got a great deal on a new one from the hobby shop.

    So far its stock, and has never been wet. I was initially intending to take her for a spin today with the nimh batteries that are included (I don't have 2 identical 7.4 packs and have no 3s packs, will be getting some zippy's most likely) but have decided that I don't want to even bother, and I think I should have a rescue vehicle present before any boating happens :)

    I intend to use as much of the original running hardware as I possibly can, meaning the ESC, and possibly the motor. We'll see how that works out for me.

    I have already put in an order here at OSE, I ordered the brass tube, .150 cable, teflon liner, bullet nut, 2 water outlets, some largere hose, and the aluminum water jacket designed for the stock motor. I wanted a dual inlet rudder but they didnt have the one that would be the closest fit compared to stock, and I wanted the trim tabs with water pickups, but I didnt see those either. In fact all the water inlets were out of stock, so I have decided to fabricate my own transom inlet.

    My hopes are to blueprint the driveline as best I can, add a second water source and run the cooling to motor and esc seperately, at that point we'll see if the motor survives, and if not Ill look for a replacement that can still use the traxxas ESC, presuming they havent issued an upgraded motor by that time.

    I also want to seal the hatch better than it is in box stock form, seems to me that is a great area for an aftermarket company to make some improvements, a little sturdier piece with the contours changed to allow taping would be great.. but the 1/4" foam stripping will likely be my immediate solution.

    Why the spartan? well, I like a challenge and part of the hobby for me is the bench time, planning and executing upgrades, that sort of thing.. it also is designed for exactly what I want, a fun boat to play around with that handles a little chop, and has a pretty impressive top speed for what it is.. I also know that Traxxas (approached corrctly) will bend over backwards to keep their customers happy.. I know that isn't an opinion that some people here share, but in my experience that seems to be the case.. and if I can use the stock motor and speedo, that 20.00 lifetime warranty seems pretty atttractive.. assuming Im not smoking them left and right..

    I looked at the UL1 superior, the Miss Elam, the Motley Crew, and this boat quite a bit, read forums about the UL1 and Spartan, watched all the videos, before coming to a decision, and my decision was this- The spartan design is a bit of a standout in the RTR boats, and doesnt compare well to the hydros and cats.. and that I would need to have one of each.. with the short run times on boats having a few to run will make for a better day playing in puddles, and I think I will eventually want to race something.. probably FE Hydro... looks like Ohio has some racing going on so I should be all good there..

    So anyway, I expect to see my parts around thursday / friday next week, and after my boat has some unique features Ill start posting up some pictures, making observations, and asking questions.. not looking to set the world on fire with this one, no desire to prove false advertising (thats been done numerous times already) I just think that set up right it should be a fun boat, even if it means propping down and running 45 mph instead of 50.

      Welcome to the forum, and have fun with the Spartan.

      If you change your mind on fabricating the transom pick up, the trim tab pick ups are available here at Kintec Racing: http://kintecracing.com/Supervee_27_upgrades.html

      There are actually for the SV27, but require only minor modification for fitment on the Spartan.

        chadrob- Ill probably end up sinking a couple hun in it, the last order was just under 70.00, simply buying a motor will put me near 2 hun :P I just dont want a 1000.00 traxxas (anything)

        I think I am going to also build one from scratch, using the Castle marine stuff, and lots of little chi-chi parts, havent decided on a hull yet for that. I like the idea of an FE tunnel hull, really.

        Dag- I may, I have seen those too, Im going to dig in my small parts boxes 1st though, I may have something left over from a previous project that will work without being a hack job. Is Kintec reliable? someone that is here on the forum maybe? I like some of the products I see there, I could definitely see ordering some of it down the road.

          I've ordered several times from Jan at Kintec with no issues. Occasionally, if stock is back ordered, your stuff arrives short an item or two, but Jan ships back orders as soon as he gets stock at no extra shipping cost.

            I just ordered a pair of the transom pickups from him, just the little single bolt design, I want to get them as low and centered as I can, I think I can get them more inboard than the inner trim tabs, and that should give me a better chance of keeping them in the water. With those and the other pieces the cooling system should be on par with other, more successful platforms out there.

            Question on thrust bearings- I see that the way it is out of the box, when I push on the prop, the drive cable moves until the back motor bearing catches the stator. This can't be good on that motor bearing, or the stator.. seems that would be a "required" part on a boat as the entire boat is being pushed from that point.. and it seems the thrust in between the drive dog and strut would actually be the ideal location..

            How do the thrust bearings available here and at kintec stop movement, are they resting on the end of the motor can, or the motor mount, or what? I cant seem to find detailed pics of how that goes together. Kintec shows a spacer available, but it looks like youd just transfer force to the front motor bearing instead of the back one? surely that cant be right? Enquiring minds want to know...

              OSE, Kintec, and Kershaw Designs have all sent my items very quickly...great vendors...I don't really want a $1000 Traxxas anything either, but between my Slashes and Spartan that was eclipsed a long time ago, lol...

                I ordered 2 transom pick up-up's, a pack of shear bolts, a stock replacement prop, receiver box seal kit and a prather s220. They all arrived in 3 days after ordering except the back ordered prather prop and Jan quickly credited my paypal account the same day I emailed him back after he included a note about the back ordered prop. Excellent ship time and service! Top notch!

                  Kintec has already sent me shipping confirmation on my order :) 9AM the monday after ordering it saturday night, can't beat that with a stick :) I am sure both Kintec and OSE will continue to get my business, I'm super glad to have found this site :) (while typing this my order confirmation has come through for OSE as well, I can't tell you how impressed I am by that.)

                  Still have the thrust questions, is there anyone that maybe knows where to find installation pictures? Pushing the boat around using the drive cable and rear bearing on the motor sounds like asking for problems with both items.. is there a thrust that will work (survive) on the strut behind the drive dog? That definitely seems like the logical place to put one.

                    Agreed, I have no clue why Traxxas would build a bullet proof product overlooking that.

                    Here's my install:


                    Boca 5mmx12mmx5mm thrust bearing and 2 tamiya bushings

                    This one
                    from Steve should work.

                    Basically you transfer the thrust to the front motor cap, not the bearing

                    You don't really want the thrust bearing behind the drive dog because it won't allow the cable to load and shrink properly.

                      Awesome, thats the pic I couldn't find, thanks. I have a Boca coupon I need to use anyway, so I'll probably go with their bearing, and Im sure I have some busings / spacers around here to take up the slack.

                      SO.. another question then.. the cable is supposed to load and unload due to thrust and decel? I understand the windings will tighten during acceleration, and loosen during decel, but I don't completely understand why you would also want it to compress and extend, it seems it would just cause wear to the tube / liner / cable. I'm not disputing the truth of it so much as looking for the reasoning behind it.

                      Another question.. I have some Park Tools Polylube 1000 bike grease, its waterproof, the right weight for the application I believe, is pretty 'sticky' and tends to stay put well, doesnt attack plastics or rubbers, and is good to 500 F, will this be an acceptable lube for the drive cable? It looks similar to what I see pictured coming out of people's strut, and it HAS to be better than the oil they included lol.. and yes, its inexcusable to ship these with an unlubed drive cable.. I checked, mine is, and has the junk liner too.. Im sure the one I have is 1st run stuff.. no rolling changes for me lol.

                        Best speed grease to get: http://www.offshoreelectrics.com/pro...od=dh-aqub9500 do it the right way, no need to risk your setup for a few bucks. If that lube you have works great, you save $3, but if it fails at (26,000+ rpm), it's gonna cost more then $3 to fix everything that gets damaged... Your LHS may have some, surprisingly mine did and the have like no boat stuff... OSE is out of stock but if you need to order some online, tower or kintec racing should have some.

                          I received both of my packages tonite, and I installed the aluminum water jacket- its a super nice piece, and installation was a snap. The 1.5mm screws came out easily, the stock cooler slid off easily (whadda joke, easy to believe its a leakin, motor overheatin' failure) and I used a little seal conditioner (green slime, its intended use is to lubricate shock seals) and the new jacket slid on easily. I aligned the outlet for the highest point on the jacket, so I shouldnt have pesky air pockets.

                          The transom water inlets are going to be a little tricky to get mounted where I think I want them, I may need to buy some tubing and make slightly longer pick up tubes.

                          I bent my stuffing tube in a very gradual arc, leaving straight tube at both ends, I will trim it and get it installed next time I can play with the boat. I realized after getting the cable in my hand that the traxxas strut is larger in dia. than the shoulder on the cable I bought, so that and the bullet nut that fits it get binned till I have a boat it will work on. I thought about changing the strut, but dont think changing hardware significantly is something I want to do to this boat.. that molded plastic transom isnt something I want to heavily alter, I like those blind holes. Plus Im not looking to sink a fortune into it.. I want to build something custom instead.

                          Sharpened the turn fins and rudder, shaped them with my dremel and then used an old knife sharpener set to put a 25 degree edge on both sides.. I stopped short of razor sharp, but they should cut cleanly through the water.

                          I've pretty completely convinced myself not to get too anxious to go to 6S with this thing, while I think near 50ph speeds would be fun, I'd like to get a little mileage out of the stock electronics, so I am thinking that a pair of 5S packs in parallel would be a great setup, plenty of available amperage, plenty of runtime, and it wont be running the electronics on the ragged edge.. and being a shade heavy doesn't bother me too much, its not like Im going to race this thing..

                          my target for being "ready to run" is next sunday (11 days) hopefully the weather cooperates :)

                          On that motor cooling jacket- the oem one had grease on it from assembly, with enough in some of the channels to obstruct flow, especially if it made it to the exit hole.. and speaking of channels, it has more rubber in contact with the can than water.. I think that is the 1st thing that should be changed on this boat.. I don't know who thought that would work on 6S doing 50mph, but they should be forced to turn in any cad software they are in possession of.. /rant.

                            I've been pretty busy, So far the stuffing tube has been changed along with the teflon liner, I am using the stock cable for now, and I found some proboat marine grease to lube it up with (yep, one of my local hobby shops stocked it)

                            I added the second set of trim tabs, added two water inlets and outlets, 2 transom water pickups, I had to make the pickup tubes as the stock ones were too short, I may have to fab a brace that uses the trim tab screws to hold them in place.. we'll see. They seem very sturdy as-is.

                            I upgraded the servo to the digital traxxas servo, so I could use my KO EX5-ur radio with it, I have a helios I use to race my cars on but dont want to risk it near the water.. for now Ill use the traxxas radio, till its dialed in and working..

                            Large diameter tygon hoses throughout, 3 water pickups, 2 routed through the esc's ports, 1 dedicated to the motor, all three on seperate outlets.. I should not have problems with water flow.

                            I know between the trim tabs and the 2 pickups I've dirtied up the back of the boat, and it will cost me some speed on the top end, but if the boat lives longer than a run or two it'll be worth it.

                            I ordered 2 4000 mah, 30C 5S lipos, to be wired in parallel.. this again will cost me some speed but should help keep the stock electronics alive a good long time.. and with this setup Ill have 8000mah and 60c continuous discharge, so I shouldn't struggle with available amperage, nor should it stress the batteries more than necc.

                            The last piece besides the batteries is the thrust washer from boca, it should be here by the end of the week, along with cells.. Im hoping to get it on the water sunday :)
