bummpy My df03 dreams are still alive. I have a big box of parts ready to add. I will post picks when I am done. Does anyone know where I can find the longer 7cell (I think) tub chassis. I saw it once but I cant find it now I want to buy it . Prolly will have to buy the c/f though I am having trouble finding the $80 one in stock now too. As a matter of interest here is a cool body kit I am buying.

anyone had problems with brushless power - causing a snapping/clicking noise under acceleration or from going reverse to forward? i'm not sure if its the slipper, diff or the actual gears. thanks! I have a slipper clutch as well...

If you still have the stock plastic rear diff halfs, that would be the first thing I would look at. After that, I have over time, running 6.5 brushless, seen the idler gears that go to the driveshaft strip out.

it has front one-way as well. I installed rear gpm steel universals, and aluminum hexes.
how loose would you run the slipper clutch? I have tightened the nut to where about 4 grooves showing in the screw.
it was running fine for the first 5 minutes and then the car seemed to slip while accelerating - but even more while going in reverse. Checked and tightened the rear diff i will have to check the idler like you recommended.
It almost seems like the teeth are skipping when I go from a quick reverse to foreward on carpet
The teeth are just too wide i think for it to skip, plus the drive train sounds just fine when off the ground and is smooth and no broken parts when i tightened the diffs.
- so either the slipper is not working as it should, or its something wrong with the slipper or i heard that sometimes the pin in the propeller joints for the shaft can also skip, but i still dont know whats causing the skips/snaps under acceleration - reverse/forward- hopefully its just the slipper working haha.

The top two shafts are Tamiya parts and are worn out. The bottom one is a Five Stars FS7038 hardened steel.

Take a very close look at the gears in your buggy. What you're describing is a worn out main or idler shaft gear which seems to be a problem with a DF03 and a high powered motor. I "borrowed" this picture from a thread on the TamiyaClub site (thanks TA-Mark):

i'll see what i find when i open up the bugggy...
I only wish i had loosened the slipper more- as i went from a stock straight to 4000kv brushless

thanks for the input! is there any place to buy these? i'm getting one anyways as it seems like a good investment. i'm having a hard time finding it online.

I do know of people running their DF03 with the 9T EzRun systems without any problems (I believe they're 4300kV.)

sorry to hear you are moving on. i still have mine but i think its just gonna be a shelf queen. or something to bring out to have guys guess what it is.
if i start racing 4wd, i think i'll head to a DB01, or the new caster buggy.

hi guys, finally got around to replacing the melted diff halves and the car runs great- had a couple of runs so far so here is hoping that it holds out. It runs much smoother than the b44 and xxx-4 over the grass bumps - very plush suspension with the trf dampers although it may just be the setup.
i had a problem with clicking from the front one way- and i opened it up to see that the gears were not greased and had worn out at certain places. I noticed that one of the 10mm x.02 shims is also missing so i'm hoping its a problem with not having the shim.
Since i did not build it(got it used) i need to know if in the one-way instructions they reccomend using one shim on each side? or is it both like in the manual for the front diff?
if so does anyone have a couple of extra 10mm shims lying around? would be happy to pay. Thanks!

Replaced my DF03s with HPI Cyber 10Bs. These Cybers are great and haven't looked back.

BTW rc champ in japan has the shafts. I got 2 from them recently.
Whats got me stuffed with my df03 is the drive cups. I cant think of a way of fixing them to be reliable. Does anyone know of a drive cup that lasts? I compared the hotbodies d4 cups but I believe they are just a little too different to fit.
edit Iam surprised you are running the stock mid shaft drive cups. I guess you cant run a alloy one up the front because of the one way.

and also tamiya is coming out with a 502x which is shaft driven, which PROBABLY means shaft is better than belt for offroad or maybe not.
#1005

It wont ballance right with lipo. I wish they would of done somthing interesting like the df03. Maybe shaft drive offset with a stickpack laying beside it. Df03 still has the best motor position I think. Thats what I find facinating about tamiya's all the gears and shafts and pulleys.Funky little machines.
