    I was thinking the same thing.

    No, Costa Rica is an independent country.
    Maybe you be confused with Puerto Rico.

    +5 for creativeness - 5 for effectiveness, I don't quite understand the point of this, you are running 23/90 which is a bashing gearing, it should keep your temps below Fail safe 180*, second: heat sink on motor will reduce your temps by 15* which is about what you got, fan on ESC will reduce 5-10* temp on average, good fan for motor will reduce temps even more. The guys at my local hobby shop have done this many times to beat the heat, but for 31/76 gearing there is nothing that will help you to reduce it below 170*

    First at all: Thanks for the review

    Now, I am testing new gearings, I made a modification to the pump connecting the wires to the connector of the ESC. (Add more voltage and it can push more water), using tubes with more diameter and less curves, with the modification I made to the ESC the temperature goes down, i am adding fans to the esc and the radiator, and all the info I said before was before all the modifications made.

    I was searching for aluminium gearbox and i found:

    http://www.ebay.com/itm/Lightweight-...#ht_500wt_1413

    http://www.ebay.com/itm/Traxxas-Slas...ht_1101wt_1163

    http://www.ebay.com/itm/390403402677...ht_2252wt_1163

    I want hear about some reviews about those gearboxes

    I have few questions about the gearboxes:

    I need a modification in the chassis to fit the gearbox?

    I am not going to buy a gearbox, is just for help a friend.

    you will def get more cooling with the full alum gearboxes. I have the Hot racing graphite/alum setup, and while it does aid in cooling, it will not do as well as the flm or golden horizons you linked to.

    I think only the rustler needs a slight chassis mod to fit the flm. The other 2 will fit all the 2wd traxxas trucks with no mods.

    DBG this project is darn impressive you have taken on and continued with, nice work man!

    Here is another avenue to consider perhaps on coolant, check out Red Line products and look for 'Water Wetter' it may interest you That water jacket is clean looking on the motor, coooooool!

    Lightbulb Update

    I changed the tubes. Now, the new tubes have bigger diameter than the old ones.
    I forget made the unit conversion.(sorry )

    Ambient Temperature: 24-25C

    Gearing: 86-23(I changed the gearings to 90-23 to 86-23)

    Motor:30-37C (Never touched the 40C)

    ESC: 30-36C

    Next time i am going to buy a bigger pinion and a smaller spur gear.

    As far as the coolent you are using.... In my full size turbo powered off road buggy I use a product called "Engine Ice" and it greatly reduced the coolent/engine temps. I don't know if that product is available where you are but it is also non corossive and biodegradable. Just a thought!!!!

    That's TOO COOL!! pun intended.
    If I did this to my Slash I could go 200miles through the desert at 60mph with ultra cool motor. (With {Plutonium 239} batteries of course)

    For a castle motor I wouldn't get the aquacraft water jacket. I would look at some aluminum ones made for castle motors. I've purchased a few for my boat and they don't leak at all. I would put a link but don't know if i can push others products.

    ^^^ I think its fine to post a link in this case as you need to reference a particular part to a particular person(reference purposes). Your not trying to turn the whole world on to the lowest price for it, but to show a member what else he could use for this application.

    Lightbulb Update

    Today I bought some fans and I installed to my radiator.
    I removed the radiator for a better view..



    Right now, I am connecting all the wires from the fans to the ESC fan plug.

    I just bought the same tranny and changed it out yesterday. Have not completed replacing other things so have not had a chance to test it out.

    Good luck with yours....

    That looks great. That is a great idea. Maybe add a fan to the radiator? Pull more air? Do you have any problem with dirt on the track?

    Little update

    Ok, today I connected the radiator fans wires to a J connector and the same for the waterpump:

    Pics:




    Waterpump:



    Maybe I am going to get a Y connector for connect the radiators fans and the waterpump.

    I am planning on doing the same thing to my 1/16 scale e-revo when i upgrade to Mamba Max Pro. Instead of adding a radiator, i will be mounting this to the body posts:

    http://www.ebay.com/itm/LOT-of-3-CRA...#ht_2071wt_742

    And i will fill that with ice. I will put the intake area of the pump through the bottom, and the warm water will come through the top , becoming cooled by the ice. i feel it will be more stable and less finnickey than the radiator method.

    any thoughts???

    I have the stock reciver on the vxl 16 merv, and i dont know much about the electrics of this project. What do i buy to attach the pump to the reciver, will it supply enough volts on my 2s lipos (7.4 v.), and would it just be easier to attach the pump to a 9v battery? would it work???

    Is the fans blowing air out or sucking it in? Cool beans!
