    where to start I guess a pic of the parts I'm going to use.

    This is going to be my power supply XL2 ESC.

    ===

    I went with the XL2 because I'm using the 1717 1650 kv motor, and have an XL2 in my 5ive. On the left is a 1515 2200 kv motor for comparison. The 1650 kv has a 5mm motor shaft so I will not have trouble picking a pinion. Also I went with the XL2 because I don't need it to be water resistant, and it was only about another $20 over a MM2.

    Ordered some 8mm bullet connector for the motor, to work with the ESC 8mm female connector. On the right is the stock motor wire 6mm male ends.

    ===

    all soldered up, and I did not shorten any of the wires.

    I went with EC5 battery Connectors because the wires on the XL2 are 8 awg, and the 1717 motor wires are 10 awg. I used a soldering iron to tin the wires, but used a propane torch to do all the soldering to the connectors, because the wires are so big. The Castle 10 amp BEC is soldered in and ready to go, I set the Voltage to 7.4v for the servo I will be using, more about that later. The XL2 is wired in series, set to auto detect and the LVC set to 3.5v per cell.

    Little more on the settings of the XL2, there is an amp limit setting that I set to 300 amps. Usually I run brake at 30%, but left it at 50%, because Frankenstein is still going to be a bit of a crawler just brushless. I never played much with the Data Logger but think it will be interesting to see some of the readings.
    The motor mount works just fine with the 1717 just need to drill out two of the holes to 5/32" (.156") then use a 5/16" (.312") to countersink for the screw heads. Marked in orange is the two holes that were drilled. During mock up, you will see later, the motor wires will sit nicely to the passenger side. You never want the wires sticking straight up on the motor, they can be damaged on a bad landing. Not much of a chance with a Summit body tho. The screws for the motor mount are 4x10ccs, that will get a drop of blue Loctite during final assembly, later...

    So haven't made much progress, doesn't bother me, I like always having a project to work on. Do have a few things done just need to post them up. Shorten the ESC wires, had to wait several weeks to get new ends. Servo Terminal 3 Pin Plug The wires are now 8" fan wire and 11" ESC wire. Takes a lot of time and patients, to install the new ends. Because I'm running the external 10 Amp BEC, I left the ESC red wire disconnected, folded over and held in place with shrink tubing. You need the red wire to run Castle Link.

    I use her for sizing, she is made out of modeling clay that I also use for balancing my tires. She has had a hard life,,,,

    The figure is used to show the scale of objects. It is not for tearing apart and balancing tires.

    87 GN...Have you made any more progress on this project? You've got my attention. One thing I've been thinking about is the weight of the motor, and the effect it will have on handling. VG Racing (ebay) has some nice stiff springs for the Revo/E-Revo that may help you out in that department. Not sure if you knew about them, so just throwing it out there.
    Does it run on gas? Nope. It's electric.

    no progress, I haven't run my trucks in months. I need to do some machining, so I can do what I want to try and accomplish, and no time. I haven't really kept up with the forums either.

    Hey 87GN
    Your truck the inspiratin to my latest updates. I am still running the 2200cc with the xl2 and wire mine with 6.5mm bullets, i was intimitaded by the 8mm. Even with the smaller one it took time fo me to solder.

    Cannot wait to try the huge motor, but just curious I wonder if the cc 2200 can handle 8s....or I will prohably gear higher on 6s , trying to get a rocket basher....extreme style.

    I am trying to bult custom trays tor 8s batteries or find ones that will fit.....without comprmising cutting up a bit of the cahssis.
    Live life to the fullest

    I read in another FORUM that the castle guys creating the original monster system said the 2200 was able to run up to 120K RPM without issue. The problem they had was a controller big enough to push it to that and still fit in the vehicle. They were testing it on the bench and tried to make it fail.

    More cells give you more RPM and less amp draw for the same amount of work. It is also the reason you gear down when running more RPM to keep the motor running in the peak efficiency range for your driving style.
    If it didn't break you can do it again.

    Hi,

    Am trying do your build E-Revo to SCT. The Pro-Line 3384-00 Flo-Tek would this fit direct to the E-Revo posts ? i had bought one and to my misery it never fitted. so i was kinda doubtful if i had bought th rite one !

    sorry the thread kind of got jumped around, but to answer your question I used the Revo Posts, and it took me a bit to figure out where I wanted to drill the holes, to align the fenders with the wheels.....

    I've been catching up here, and I love this thread. I have an old 2.5 revo that I converted to brushless, and I'm now amassing parts to turn it into a summit with revo diffs, a proper plastic chassis, and a summit tranny. I had no idea about the shims to adjust the caster, I love how you explained the roll center settings, and all the information about getting a sharper turning radius. I want to build mine up to be a fast ish trail truck that can crawl some and do a little jumping and such too, with a tekin t8 1900. I'll rely heavily on the information here to get mine right!

    I've also considered building it with the slayer arms but still to trail and crawl. I love that scale look more, but I feel it would be sort of counter productive.
    460, straightpipes, buried throttle, nuff said :D
