    Summit by jesi (56k warning!)

    Hi!

    First, sorry for my bad english =)

    I live in Finland, city called Tampere ( http://maps.google.com/maps?f=q&sour...186.328125&z=3 )

    I'm founder & admin of local RC rock crawling forum / community.
    So i have many years of knowhow for crawling, hi-powered brushless setups/conversions and general RC stuff.



    I did get Summit for my boy, but as you can guess, i drive that some times.



    Boy & summit (order from amainhobbies.com, because local dealers do not have Summit):










    After 10min driving:









    One week later:

    Some driving pics:














    Boy drive with 2* 8.4v/4000mah & 2* 7.2v/4000mah nimh, because lack of lipo cut-off.
    I'm using 2s/4000mah lipos.


    Here is my charger:


    I can charge all four batterys at same time, it takes about 25min (all four empty batterys to fully charged).

    Some extra protection for RX & T-Lock module:






    I did also put T-Lock wires "wrong way", so first lock is off, then only rear lock, then both locks.
    Now it is better to drift with only rear lock

    Also i did put some silicone grease for RX-box O-ring and wire inlets, just for overprotection =)


    Change stock esc & motor connectors to 6mm bullets:





    I'm planing to mount Mamba Monster esc and some nice brushless motor.
    Only problem is, MMM is not waterproof, maybe not water resistant at any means?
    Anyway, here is my solution:

    http://www.youtube.com/watch?v=sM3-CCXp7Dw
    (testing with some old esc)

    Get some nice box, make inlets for wires, fill that up with PURE silicone
    oil, remove cooling fan, sink MMM in that oil, close the box?

    So, box & oil is protecting esc from water, also it is transferring heat away...




    And some playing around:

    Okay.


    First i did try that XL 2800kv motor with Mamba Max (also CC-BEC), at 4S 4000mah.
    I drive about 7min _very_ light bashing, then esc goes temp cutoff (newsflash?, not.)



    Today i did get little box (IP66) and make rugged prototype v0.00001:










    I make inlets, filled that box with PURE silicone oil, drop esc in and close the box.



    I drive about 15min, very hard bashing.
    The esc box was about hand warm after that, and no temp cutoff or anything else problems........


    So, now i have fully waterPROOF brushless Summit.




    Now i need some nice sensored motor & esc for better crawling =)
    What you recommend?

    A water-PROOF MMM in a Summit...

    My question would be, how does he turn it on and off???

    Sorry for delay.

    Open RX-box, there is T-lock module:


    Put "A" wire to "B", and "B" wire to "A".

    great job there, do you just turn the module around or the wires.

    Now many hours of crawling with both summit's...

    I did put temporary weights to front of car, just for testing:








    I used 1:1 car wheel balancing weights, about 1.3lb/600g.
    Result:
    - because tires have so good grip, steering servos stall some times in "bad places".
    - torque twist

    But, both are easy to fix.
    I say, stock tires are better than moab 40 series.


    Today we drive in our best crawling area (what i know), i have been driving at that place many many years, super & 2.2 series comp crawlers.
    So, can compare Summit crawling performace to my old cars, and it is GOOD!

    Okay, there is some places what summit did not handle, and some did need some brutal throttle using =) But average value of performance is in my scale: 4.5 (scale 1-5).

    (now both summit's are 120% factory stock, except that temporary weight in red car)



    Some pics:












    (last pic: this place has six old anti-aircraft gun mountings, from war time (1939 – 1944), there is also monument for lost soldiers)




    edit:
    BTW, here is specs from that oil what i use in my "project: oil-cooled summit":
    Baysilone Fluid M 500

    Why do you put the esc in silicon, instead of just leaving it empty, and wouldnt it ruin the esc with the fan? and where did you get the box you put the esc in?
    Are you an RC addict?

    Erh?

    If there is no liquid, where the heat is going?
    Now oil is taking heat from ESC and transfer that to box, and box has so big surface area that it evaporates that heat away.

    I did buy that box from local electronic parts supplier.


    Now i have bigger box and better inlets, so it is v0.00003 now




    But, now i do have so much Real work to do, so i did put this oil-cooling-project to break.

    (about 100-120hour per week, cleaning roads and yards with:


    Yes, i did wash my car at lunch break )




    Btw, just order Red summit (for myself)....
    So, now i can race with my son

    You mentioned that you run a rock crawling group. What is your opinion of the Summit compared to the dedicated rock crawlers? (I see you bought another Summit so that must say something )

    Yes, i have been driving many years crawling with "real" rc-crawlers, as in 2.2 to super series.

    I'm Very satisfied Summit's crawling capability.
    Ok, need some tuning and can't race with Super-series crawler, but very good for "sunday crawling" =)

    Tires are good!
    Only crawling-tuning what i planed to do is fine tune suspension and put some weight to front.
    Not sure what to use, but normaly i do use:
    - 1:1 car wheel balancing weights, mounted inside of tire, to wheel out-ring.
    - salt water, inside of tire.
    - BB lead pellets, inside of tire.
    - External temporary weight.


    Also planing to use brushed e-revo motor mount, so i can use dual crawling motors.




    (with my friends Axial SCX10)

    ha ha!

    Our local shops do get trx from Minicars, from Sweden.
    So, we have first summits in shops at end off this month or next month. And the price is BIG!

    Yeah I know. (I manage a local hobby shop in Uppsala)
    And Im friends on a personal basis with two of the guys packing and shipping at Minicars so I get updates on a daily basis... The price is going to be pretty high but still worth it I think.

    More trial driving in old forest machine trails:










    I did put mamba max with stock motor.
    (4s lipo and CC-BEC at 6v)

    The dragbrake is avesome!
    When i drive at first gear, WOT, then release throttle, all wheels stop instant and car stops with rear in the air =)

    Also, i did get rid of reverse delay.


    Some data:

    - 1.5h
    - 3550mah
    - 575w
    - 44a
    - 55wh
