Upgrade Mega/BLS plastic transmission to BLX metal

[Bladerunner]

Its 32p

 

[blx84]

This THREAD requires SERIOUS clarification.

1. I have Mega Granite #102657 and purchased all the parts on this list. Is this unit pre 2014 or NOT?????

2. I spend the evening dismantling the rear end to find out I also need AR310378 and AR310399.

Why is that NO CLEAR METHOD to determine what was made before 2014 and what was not?? I bought this thing less than 30 days ago and have had to fix several items and now discover this product is 3 years OLD???

Let's not forget the BLS ESC that smoked in less than 10 days which also smoked the BLS motor (after purchasing and upgrade). Ended up spending money on a Castle Sidewinder 3 combo.

And I had to replace the spur and pinion last weekend because they were dull.

This is complete and total GARBAGE.

did you fix problem if so how? i have a upgraded arrma granite mega with on BLS parts like the esc an the 3600KV motor with 2s lipo. i havw went thru 3 trans. help? lol

Brand new here. Long story but I have a Granite and a Fury. I ordered a new motor and esc so I will need a diff solution.

I have gone through a few of the mega transmissions - usually the pin in the gear attached to the slipper shaft eats through the plastic.

Just fixed last week - with the metal transmission parts mentioned in the first page of this thread. Really is bulletproof with a 4000 kv brushless 3065 size motor and 2s.

Be sure to shim tightly. I used two teflon washers under the pin of one of the diff gears to make it tight.

Thanks Ekfchan , I was curious why many of the parts are not available from
Armma ?

I quickly skimmed over this and I saw a couple of options for other brand diffs and ball diffs. As long as parts don't become scarce I will use what's available.

 

[Ekfchan]

They are all Arrma parts - BLX parts. I ordered from Tower Hobbies and Amain

I also ordered all the parts in this thread from Tower to upgrade my mega Raider. Seems strong as anything so far!!! I did not add extra shims -- hope that doesn't come back to bite me.

Ok , good info so far . I went and ordered a brushless motor and esc from Hobby People. I did this before checking for parts or signing up here. It says it's a 4T motor. That might a bit overkill for this car but I got it for a good price.

That looks like a nice find to me!! I went with an RC Gear shop 3900 kv and I love it. I used an Arrma BLX ESC, which was easy plug and play, but I'm sure once you get yours dialed in and programmed you'll be good to go.

Have fun!!!!

 

[jamnM]

It's all about fun.Thanks

I finally got it all together and working with stock gears so far.

Hi, I want to get this Metal spur gear for my Arrma fury. I have gone through two spur gears so far with my Castle Sidewinder 3, and I really want to upgrade to metal. Would this work? http://www.hot-racing.com/index.cgi?partnumber=SARM357;c=689

Yes it will work but you need to change your motor pinion to 32 pitch

Brushless windings are mostly stated by .5T
Given that 4000kv is often associated with 8.5T, I do not think they mean the windings.
Also 60A would be insufficient for such a fast motor.
Maybe the mean the amount of poles, that would make sense.

Nevertheless is sounds like a good motor and deal!

Can you link a part number for a 32 pitch pinion also would this gearing setup work with my motor and esc I have Castle Sidewinder 3 Combo and being 2wd I can't put a fan on the motor

Here you go:

#AR310421 PINION GEAR (15T, 0.8MOD)
#AR 310405 (57T 32dp Granite/Vorteks/Fury/Mojave)

0.8 modulus and 32dp modulus are practically equal, thus fit perfectly.
Make sure your motor has a shaft diameter, which will fit (3,12mm)
If you have a Castle motor with a 5,0mm shaft, you can buy aftermarket pinion gears 32dp/0.8MOD

~I don't know much will that pinion work with my spur gear if it doesn't I'll take it up to my local hobby shop to see what they say. http://www.hot-racing.com/index.cgi?partnumber=SARM357;c=689

As the metal version from your link should be a copy of the original Arrma version + it is 32p: Yes, it will work

Thank you so much
