    Changing Spur Gear - Query

    Hi

    I'm trying to change from 48p to 32p gearing.

    The old spur looks like this:



    But the new one is like this:




    So the clutch pads on the 48p bowl shaped spur sit in a little basket inside the spur but the new 32p spur is flat so how do you fit the pads?

    Thanks GRipdog.

    That's kinda what I figured once I had a look at it but nice to get it confirmed. I did like you said and they seem to run fine. Got the mesh set up nicely - starting to get a feel for it now. What's that Mod1 gearing on yours? Looks pretty high. That's a HUGE pinion.

    Should stop this happening again (on my 48p gears)-

    it looks like you are using a 32 pitch pinion with a 48 pitch spur. Pics can be deceiving though.

    Yeah it does look like that doesn't it?

    Pretty sure it was 48p but, being a n00b, it's possible that I don't know what I'm talking about.

    It would certainly explain why the teeth stripped in about 5 minutes of gentle use.....

    I've also figured out it needs a wheelie bar too!

    How is your slipper setup? Might need to back off the nut a little.

    Yeah it's ok - now.

    I read up on setting up slippers and have more of an idea. I think the one in the photo had been bolted back on to take the picture hence it looks a bit tight.

    Or I could have no idea what I'm talking about etc etc.....

    Thanks for all the input guys. You lot really seem to a helpful bunch on here.

    Got it running great with 54/16 32p gears. 3S LiPo, Racerstar 3660 3800kv Brushless Motor and 60A ESC.

    It runs rings round my brushed E-Maxx but, with the standard tyres, was pretty hopeless on grass. Spinning the wheels almost all the time even when you fed the power in really gently.

    On tarmac it was mad. Again, power delivery made it hard to keep the front end down. Barely ever got near full throttle. Great fun though! Driving technique definitely needs improvement. The wheelie bar arrives tomorrow which isn't a moment too soon.

    The wheelie bar only helps to keep it from flipping. You still wont be able to steer it, LOL! But it does make for a good show and is fun as heck!

    I have the swami on my rusty that is like 10 degree and it still gets all crazy. If I were to by another it would have "no" bend in it. It would come straight out from the chassis. Of course running a 2650 kv motor doesn't help. lol

    With the stock Alias pin style tires? Those should hook up pretty well on grass. Are they worn down?

    Oh yeah, those are worn down quite a bit. Looks like you are on the last stage of the pins. That would explain your lack of traction in grass. You'll probably want to upgrade to some aftermarket tires like Badlands, or trenchers. They'll last a long time and hook up really well on an surface.

    Thanks RC N3RD. Will do.

    Anyway, had my first ESC fire.

    Ran through a few puddles and maybe the cheapo Racerstar ESC isn't too waterproof?

    Anyway, smoke began pouring out of the car so I unhooked the bodyshell and saw this. I then stopped filming as the ESC burst into flames and I managed to detach the flaming ESC from the rest of the car before it was all engulfed.

    Oh man that sucks! Might want to get a Hobbywing esc. They are pretty reliable.

    Thanks.

    Had a spare ESC I could stick in so got it running again the same day.

    The kids loved it! Now every time we drive past anyone having a bonfire they say, "Hey look! Someone's driving a Rustler!"

    I've actually got a Traxxas VXL ESC motor combo coming next week so I might just stick that in.
