Will I get crucified if I buy a steel rovan or km gear ? not like it's a clone of anything

Go for it. I'd be curious to see their wear characteristics.

I'm still completely amazed that you're killing spurs. I've been running the stock HPI 57t for over a gallon now on my OBR 34 and it shows no wear. I'm still running the stock transmission plate (modified for the TR HD carrier) and the stock plastic transmission shaft carrier.

Never said I bought it?
@AnubisBC @Seandonato73 well can't find jack poop ?‍♂️ all the braces are stock (orig HPI) , and the layshaft carrier is the stock like Anubis', top plate is madmax obv. So no idea wtf is going on. Nothing is bent or damaged. I think the hostile are just brittle trash from age or whatever. Also keep in mind, they aren't stripping right away , it's after 5 or so hours.

also the thing is, all the braces are all stock, there is nothing aftermarket so it should be just the stock mesh. gear plate is slightly twisted by the breaks but when i remove the plate the mesh doesn't change. im leaning with the gears just being poop

I remember fixing a weed eater one time for a gardener ,the clutch bell was completely in two pieces ,I had never seen one do that before ,
the problem was ecessive heat from the guy's old man using it ,when he uses it ,he was lugging it while cutting ,it over heated the bell an
wore the bell in two ,so if you are constantly lugging your buggy the shoes isnt getting full contact in which will create the heat ,might can
try a different tension spring!
 
@Z.hb71 If you can get a 17t pinion for your clutch bell, I will be glad to send you one of my stock 57t spurs to run with just to see if it is actually the Hostile plastics. My stock spurs are a couple years older than even the oldest Hostiles.

All this being said, I want to touch on your clutch ?... for one second. Are you running the FS Racing clutch along with the white coated spring it came with? If so, you aren't getting the promised engagement numbers.

I've been running it most of the season, and I got the feeling that it was far lighter than 8k. Seemed like I was getting clutch engagement at a far lower throttle than I expected: it was barely over idle.

Turns out I was right. The white spring on the FS clutch I bought was closer to a 6k spring. My DDM 8k springs showed up this afternoon and they are FAR stronger/thicker/more of a pain in the arse to install, and it takes a lot more throttle to engage the clutch. My case in point: clutch springs.webp


This could be part of the reason you aren't seeing any low end torque at the moment.

I still don't know why you are shredding spur gears, but heat could still actually be an issue running 19/55 if your engagement point is low due to a softer clutch spring.

I'll report my own results once I can get another run on the record. Still waiting for shock parts to arrive...
 
Z my spur and pinion have been on for about 9 months now with no wear, also been through 3 pistons and barrels plus a complete engine in that time. For price of a bearing kit from likes of RCModels or DDM I'd do a bearing replacement.
The bearings may feel tight when cold but once warm could have too much play or even a cracked race. Think a bearing set is about the same price as a hostile spur IIRC.

I'm not running an fs clutch anymore . Running a standard zen with a ddm 9500 spring.

This could be true. So your suggesting I go with another plastic gear but replace the old (possibly bad) bearings and see what happens?
