Im using the HW fan and heatsink combo for $10. Its a little big and need to squeeze the heatsink to fit the motor. So far no fan breakage issues after so many abuse. The powerhobby set up I have only lasted 10 min. https://www.amainhobbies.com/hobbywing-c4-motor-heatsink-fan-combo-hwa86080130/p279175
Well... Crap. Really jumped the gun on that order lmaoMOTOR HEATSINK 4074 (ARA390299) | ARRMA - Designed Fast, Designed Tough (arrma-rc.com)
This above is the the correct fit for a 40mm diameter Firma 6s motor. If using the this motor. Buy a quality HS 40mm fan to mount on top of this HS. The matching Arrma stock fan wont last and is also slow.
I tried the HW HS and Fan. The fan is garbage and the HS is a very poor fit. Little thermal transfer. Been down that road. Tried this HW. It is much cheaper for a reason. Have 3 here that just sit in the bin. All 3 fans crapped out. (cracked) The HW HS/Fan is designed for a 44mm motor can. HS's must fit precisely or they don't transfer heat well enough and actually keep the motor hotter than using just a Fan alone with no HS. I noticed myself first hand, a fan alone was better at cooling than using this HW HS/fan combo.. Bending any HS to MAKE it fit to the wrong size motor is incorrect. There will be poor contact surface area.
If you have a 44mm motor then it will work.
Does the stock system monitor the motor temps too?Need a 15T pinion at minimum to get anything out of a Kraton. The Long wheelbase chassis that it is will feel underwhelming and not pull up if you don't gear it properly.
Check ALL your ESC settings. Something is a miss here. Almost sounds like you are describing a RTR 8s rig out the box there. With no get up and go.
Why chicken out on a 17T pinion. "Thermal Cut OFF" has your back dude.Hope you got a temp gun. Sounds like you don't?
Monitor your temps. That is how its done with gearing changes.
A lot of reviews saying one of the fans came not even working :/
I'll give em a shot. Wouldn't happen to have a link to one of those adapters, would you?
No, you would need a sensored motor for that.
Thank you! Enjoy your babies.
Too bad I didn’t get some hardware while I was there because the wing mount bolts sheared when I thought they pulled out
Hopefully I’ll get the oil in the center diff changed tomorrow and source some overpriced metric hardware from ace. Still need to decide on fan situation. Thought about buying a crisper and fixing them, but for the cost of it I could just get 2 more fans that aren’t total garbage.
Think I’m going to use 5mm longer ones so I can unscrew them from the front if it happens again. I finagled the shock tower off and chucked the bolts left sticking out in a drill and unscrewed them.
are those "wear" marks into the metal or the gasket? it looks like the lsd plate were installed slightly off square previous install and forced down.. it doesn't look like wear marks to me.. but could be wrong
As said already, thicker diff fluid all around will change this thing completely. Don't be afraid to put 200k ot higher in the center. I started with 200k in the center, and the difference was crazy, I now run 500k in it. Atleast 100k in front and rear. Also, stock they come with very little fluid in them, so you should check it out if the box. Also had very little grease in the housings. Definitely start with fluid and punch settings. I promise you won't be underwhelmed anymore. Be careful with pinions, 12 is safe, 15 for bashing will cause some heat issues with alot of hard throttle for long periods of time.
