    Another ESC gone?

    in General - Electric

    What temp? I've got my system running so the battery peaks at 45 celcius, motor 70, esc 50. That's as far as I'm willing to push. Been like that for a long time.

    My gut feeling is the 2-3s escs are not really liking 3s even tho the specs say yes. If you can fit it in I think you should try a 4s Hobbywing SC8 or similar. The SC8 is prob around the smallest footprint in terms of a 4s 120A capable esc.

    Unless someone else knows a smaller one.

    The SC8 states that with a 3s lipo attached motor kv should be below 4000kv so it will run your 3500 on 3s easy 

     

    Now reading the specs of the SC8 I'm thinking the smaller 2-3s types may only be able to handle 3000kv ish with 3s which could be the problem. At or over the limit on volts and KV.

     

    I just spotted the Hobbywing Max 10 :thumbsup:

     

    well im putting the Traxxas motor on shelf for a short while - and gonna run with the donor Losi 4700kvh, just because of the fact - its looking like the motor could be killing everything

    Why cant castle max the mamba max again - it was a cracking ESC

    Two cylinder nitro engine......

    In 1 revolution of the crank you will get 2 power strokes = double the power (torque)

    Rpm will not be affected in the increased department, probably loweres due to double resistance from compression and double friction

    Itd be cool but probably not viable... in an rc

    100A constant pack for a 120a esc??

     

    Oh, and hobbyking esc's are a bit crap, in my experience.

    I thought Hobbyking was alright lol maybe not?
    100A maxed motor with a 120A Constant ESC (480Amp Burst)

    The esc in thoery shudda been perfectly happy with it....

    cogging issues will be a rubbish lipo  or faulty motor or ESC.  But as i said before a bad motor will destroy the ESC

    But the Suspect ""bad motor"" Ran perfectly fine for 5 1/2 packs
    If it was "bad" it'd be from the word go

    maybe the lipo is the issue? could be - but again why would appear to be faulty after 5 1/2 packs from last one?

     

     

    Eitherway - confirmed dead esc, losi motor's replicating same fault....

    Engine stats

    Go 1 of 2 ways about it then

    Get a faster RPM engine - which will give you more speed - but possibly loose a little on acceleration
    or go for a bigger torque engine and gear it up

    Tbh if your after like a lightning blistering fast car - time to go electric....

    Also - what % nitro are you using in the current engine?

    Bit of an RC rant

    in General RC

    Posted

    Chopping new models is okay

    But to be worthwhile u need to be fast on the ball...

    I brought a trophy early version and split it up and shoved it on ebay

    Some parts took months and months to sell....

    Some sold like hot cakes

    Engine tyres shell shocka sold quick...

    Small things like wings body and other bits didnt sell quick

    As a lone seller non buisness I did make a profit at the end....

    Sell right and its totally do-able

    leaky crankshaft

    in General - Nitro

    Posted

    The crankshaft in my engine is leaking out the back of the engine into the pullstart at high pressures (which means I get covered in fuel and green goo from the pullstart when I pull on it). Also,at higher temperatures, air leaks back out of the rotating port under the carb, around the side of the case and back up. This in turn restricts fuel flow as the pressure pushes it back. I don't fancy paying loads of money for a new crank, might even need a new case which means it would be better just to buy a new engine. Is there a magic way to seal it with something? 

    You sir by the sounds of it sound like you need todo an engine sealing

    Basically using a sealant you seal the engine up to stop air leaks and stop the fuel leak out

    Make me wonder if the seals have failed on yours.... which sealing putty shud cure

    But means engine stripping takes longer as you have to reseal

    Ill see if I can find the guide with it on
