VooDoo,

Clarification please...

Is step 3 of the manual incorrect? The head of the screw is away from the spur gear in this step. That puts the head on the left side. I have run the Associated RC10GT diff in all of my nitro oval cars. If the diff bolt is a traditional thread, as in the GT, then you are correct, and the manual is wrong.

I am taking this on its maiden voyage in two weeks, and I don't want to melt the stock stuff.

Anyone here is welcome to chime in.

Personally now run the Spec-R gear diff... but I ran the ball diff fine for loads of runs at TITC with the screw on the left. Think I only rebuilt it once the whole week. Was using the alloy diff halves mind, but that was all.

just speaking from what we've experienced back here in the PI... although most of us switched to the alum diff halves already and just opted to run the head on the right side to be safe.

be warned though that the stock diff is crap... get the black TRF201 gears and the alum diff halves for your own peace of mind.

(local TAC race rules don't allow the SpecR gear diff)

After almost one year and often used i've changed the plastic inner gears, they were the original gears from the kid.
I never had any issues (so far) with those gears, so i changed them again with the white ones.
We run with a tamiya (brushed) GT Tuned motor at the belgian tamiya cup.
I guess it all depends on how the pilots drives his car, i'm not the kind of a agressive driver.

I've been looking at putting a silver can in my YR-F2. Someone reported that David June used a FDR of 3.75 on a silver can in a FF03. I know that kind of gearing works fine in a direct drive car because I've done it in my RWD, direct drive, IRS TC. Will I need to fan cool my silver can in my YR-F2 at a FDR of 3.75? Thanks, Don

Pretty vague question. Quick answer. need? no. want? yes.

Long answer, 3.75 is for top end speed with no care to make the 15 dollar motor last. We have no idea where you run, how long you run, the temps, etc etc etc etc. Gear at 3.75 and temp your car. Do you own homework. My homework says @3.75 motor wont last more than a few runs.

OK-you're right- I really didn't want to smoke it. I just haven't done that much with silver cans in a car with a gearbox. Thanks, Don

does anyone have a good setup for asphalt with spec r diff?

the car has loads of understeering

Hi,
which type of oil are you using?

The seller of my gear diff reccomended me a 800 oil but I got a lot of understeer. So I tryed a Mercury marine grease with bad results and now I'm waiting for 50000 and 100000 diff oils.

I'm running a Sport Tuned in my FF03, I'm a basher not a racer but sometimes I use it on a small nitro track, I need to know the ideal pinion/spur gear ratio to use.

^4.5-5.5 fdr. start higher and go down.

Anyone care to share their setups?

Hi all.

I'm looking at getting a Tamiya FF03 (not the pro version) and running a 15t motor.

This will mainly be used for carpark racing (bashing).

Besides the obvious bearings, is there anything else I should be considering? ie. pinion, gearing, etc. (I already have Radio / ESC sorted).

I'm no good at working out gear ratios, so if you have any suggestions on gearing, please let me know what tooth pinion/spur to use

Keep in mind, I'm not looking at spending much in upgrades at the moment, just want a basic car that the 15t isn't going to destroy

Cheers guys - I look forward to your thoughts.

Dave.

^I believe it comes with bearings.
Get aluminum spur gear mount, metal diff nut, aluminum diff joints/outdrives, maybe the reinforced internal gears and maybe the trf shocks

Universals too, some say dog bones work ok though.

Hi Dave, my son & I both run one & his is almost stock (we both have the alloy spur gear upgrade), but he runs dogbones, etc. whereas I have virtually every hop-up you can imagine & he has now out-qualified me several times (I taught him well ).

The other thing that we did on both cars was bearings on the steering & front suspension rocker arms.

We run 27x1 stock motors & the standard gear setup is fine. You may take advantage of the fact that the FF03 can use other brand spur gears & therefore you can use 48dp/ 64dp pinions, if you already have them, saving additional cost. Ratios are difficult things to recommend as there are other factors to consider; track layout, style of driving, temerature, etc. Because you're running a hotter motor, you may need to use a smaller pinion, especially if you are doing a lot of stop/ starting.

I hope this helps.
