I just purchased a hyper 8 port and started in the break in process and have burned up two spur gears already. Is this normal? or is it just not seated right? Also if there is such a thing as a hd gear for the savage please let me know. Thanks
 
I know many people that is running a hyper 8 with stock gears and have yet to strip one yet, myself included.

Those that I have heard stripping spur gears, the majority was due to incorrect mesh between the spur gear and clutch bell.

Since you had to install the engine, I would suggest that your mesh is not quite right (just as WoodiE commented). That would be the first thing I would check.

Any time you fry a spur gear, the cause is most likely poor mesh or something that allowed the mesh to go.
 
POOR MESH IS MOSTLY THE CAUSE, but if u jump alot with the savage, try losening the slipper a bit, thats how i fried my spur, slipper to tight, and alowed no give(had upgraded axles)
 
To be more specific than "poor mesh", your engine is sitting too far away from the spur gear. The gears on the clutch bell are meshing too loose with the spur gear. When the engine give the power, the clutch teeth are killing the spur gear. Also, putting the engine too close to the spur gear can also give you problems (wear out your bearings).

Try this: put a piece of paper between the spur gear and the clutch bell. Push the engine put next to the spur gear and give it a few turns to crank the paper in and out. Then tighten it down in that spot. It works great for me.

I tried the paper trick and it works, but I tighten the mounting screws just enough so it can be wiggled a bit. Then I shove it foreward so that the front two bolts are up against the slots in the cassis. I wiggle the engine to the left so that the spur spins without binding and there is minimal free play between the spur and the bell. then tighten the piss outa the mounting bolts and go bash. Seems to me that the slots should be parrallel with the spur which should line up the clutch bell with it. Cockeyed alignment would wear out the spur too. The paper trick (if you're using normal printer weight paper) leaves a little bit more of a gap.

Hey Rob, you a hardware or software guy? Hardware Tech and network guy myself.

Whitt.
 
cool another computer guy! There are a lot of us around. I do hardware to the extent of changing components. I have sodered on a motherboard once, but that's about the extent of that. The majority of what I do is software. Computers are oposite of R/C. They don't break physically, they break on a non-physical level. It goes without saying that I don't work much on unix based OS's... I'd be out of a job or I'd be very board. hehe. :D

I'm sorry to hi-jack the thread but I think this guy got his info about spur-gear meshing. ;)
 
Thanks. Slinging h-ware and f'n with windows is all I do most of the time. It'd be nice to be uncle bill, then you wouldn't have to worry about goin broke strip'n spurs.

I saw a thread on this subject last night or so on another forum. Some company is gonna produce metal spurs. If I find that thread again I'll post a link here. The mind is the first thing to go, and EM radiation doesn't help a bit.

Update: Here's the link...

I just got an email from robinson racing about the steel spur and here's what I got:

We are making a steel spur, (about 60 days)

I should have also asked if they were gonna do a spread of teeth sizes, but I didn't.
